    Full Text Available La conservación de la biodiversidad cuenta, entre sus principales mecanismos de intervención, con las áreas naturales protegidas. En el alto Golfo de California (AGC se ubica la Reser-va de la Biosfera del Alto Golfo de California y Delta del Río Colorado, en la que subsisten especies de alto valor económico, así como especies en peligro de extinción. Este último factor justificó el establecimiento de la reserva. El estudio analiza la efectividad de la Reserva del Alto Golfo como mecanismo de protección de los recursos naturales, en particular de las que están en riesgo de desaparecer, así como de comprobar si los pescadores han mejorado sus condiciones de vida tras la operación de esa área natural. La exploración se llevó a cabo mediante la aplicación de una encuesta a los pescadores. Se sugiere que es indispensable un gran esfuerzo, de autoridades y grupos organizados, para encontrar soluciones al manejo de la Reserva, a fin fijar un programa que permita la recuperación de las especies en peligro de extinción, elevar la calidad de vida de los pescadores y con ello garantizar un equilibrio entre la conservación y la sustentabilidad de la pesca y de los pescadores en el Alto Golfo de California.

    We investigated the growth of straminipilous organisms on the skin, muscles and liver of herbivorous pirapitinga (Piaractus brachypomus) and carnivorous piranha (Pygocentrus nattereri) in water of three different eutrophication levels. Sixteen straminipilous organism species were found growing on the investigated body parts of both species of fish used as baits. The higher number of species was found on the baits of carnivorous species (15) when compared with the ones from the herbivorous pirapitinga (10 species). The highest number of straminipilous organisms species developed on the skin of both species of fish. The highest number of species of straminipilous organisms was observed growing in the water of the BiaBa river (middle eutrophication), while the lowest number occurred in the baits of vessels with water from the Dojlidy pond (low eutrophication).

    Red-bellied piranhas (Pygocentrus nattereri) are widely caught with different intensities throughout the region of Solimões-Amazonas River by local fishermen. Thus, the management of this resource is performed in the absence of any information on its genetic stock. P. nattereri is a voracious predator and widely distributed in the Neotropical region, and it is found in other regions of American continent. However, information about genetic variability and structure of wild populations of red-bellied piranha is unavailable. Here, we describe the levels of genetic diversity and genetic structure of red-bellied piranha populations collected at different locations of Solimões-Amazonas River system. We collected 234 red-bellied piranhas and analyzed throughout eight microsatellite markers. We identified high genetic diversity within populations, although the populations of lakes ANA, ARA, and MAR have shown some decrease in their genetic variability, indicating overfishing at these communities. Was identified the existence of two biological populations when the analysis was taken altogether at the lakes of Solimões-Amazonas River system, with significant genetic differentiation between them. The red-bellied piranha populations presented limited gene flow between two groups of populations, which were explained by geographical distance between these lakes. However, high level of gene flow was observed between the lakes within of the biological populations. We have identified high divergence between the Catalão subpopulation and all other subpopulations. We suggest the creation of sustainable reserve for lakes near the city of Manaus to better manage and protect this species, whose populations suffer from both extractive and sport fishing.

    Biomass Burning observed during IAGOS - CARIBIC Since May 2005 the CARIBIC passenger aircraft (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container - Lufthansa, Airbus 340-600) measures ˜100 trace gases and aerosol components in the UTLS (9-12 km altitude) on 4-6 consecutive long-distance flights per month. Volatile Organic Compounds (VOCs) are measured with a Proton-Transfer-Reaction Mass Spectrometer (PTR-MS). Worldwide ~1.3 Tg/y of acetonitrile (CH3CN) is emitted into the atmosphere almost exclusively from biomass burning (BB) together with other VOCs (e.g. ketones, aldehydes, aromatics), CO, CO2, NOx and aerosol particles. Therefore, and due to its rather long tropospheric lifetime of ~6 months, acetonitrile constitutes a reliable BB tracer. Based on the signal of acetonitrile and CO we checked several algorithms to detect BB plumes in the IAGOS-CARIBIC data set. It turned out that the most intense BB plumes were sampled during summer over North America and during autumn over South America. The results will also be discussed with respect to biases due to flight statistics (i.e. destination, flight season, sampling of tropospheric and stratospheric air, etc.). Two flights that took place during the strong ENSO (El Niño/Southern Oscillation) event in July 2015 between Munich (MUC) and Los Angeles (LAX) will be discussed in more detail by taking into account other VOCs and aerosol particles. Here acetonitrile mixing ratios of up to ~1100 pptv were sampled over Greenland ~0.5 km above the tropopause. It is shown that the sampled air originated from Northern America / Canada where strong wildfires took place. During the flight from LAX to MUC the boundary layer air entered the upper troposphere by isentropic quasi-horizontal mixing and not by fast convective transport. The correlation of some VOCs (i.e. acetone, methanol and acetonitrile) with CO will be discussed and contrasted to findings from the literature. It is

    Full Text Available In the tropics, studies on the ecology of host-parasite interactions are incipient and generally related to taxonomic aspects. The main objective of the present work was to analyze ecological aspects and identify the metazoan fauna of ectoparasites that infest the piranha, Pygocentrus nattereri. In May 2002, field samples were collected in the rio Araguaia basin, State of Goiás (Brazil. A total of 252 individuals of P. nattereri were caught with fishhooks and 32.14% were infested with ectoparasite crustaceans. The recorded ectoparasites were branchiurans, Argulus sp. and Dolops carvalhoi and the isopods Braga patagonica, Anphira branchialis and Asotana sp. The prevalence and mean intensity of branchiurans (16.6% and 1.5, respectively and isopods (15.5% and 1.0, respectively were similar. Isopods were observed in the gills of the host; branchiurans were more frequent where the skin was thinner, and facilitated attachment and feeding. The ventral area, the base of the pectoral fin and the gular area were the most infested areas. The correlations between the standard length of the host and the variables intensity and prevalence of crustaceans parasitism, were significant only for branchiurans (rs = 0.2397, p = 0.0001; chi2 = 7.97; C = 0.19. These results suggest that both feeding sites and body size probably play an important role in the distribution and abundance of ectoparasites.Nos trópicos, os estudos sobre a ecologia de interações parasito-hospedeiro são incipientes, sendo a maioria de cunho taxonômico.

    Over 75 tsunamis have been documented in the Caribbean and Adjacent Regions over the past 500 years. While most have been generated by local earthquakes, distant generated tsunamis can also affect the region. For example, waves from the 1755 Lisbon earthquake and tsunami were observed in Cuba, Dominican Republic, British Virgin Islands, as well as Antigua, Martinique, Guadalupe and Barbados in the Lesser Antilles. Since 1500, at least 4484 people are reported to have perished in these killer waves. Although the tsunami generated by the 2010 Haiti earthquake claimed only a few lives, in the 1530 El Pilar, Venezuela; 1602 Port Royale, Jamaica; 1918 Puerto Rico; and 1946 Samaná, Dominican Republic tsunamis the death tolls ranged to over a thousand. Since then, there has been an explosive increase in residents, visitors, infrastructure, and economic activity along the coastlines, increasing the potential for human and economic loss. It has been estimated that on any day, upwards of more than 500,000 people could be in harm's way just along the beaches, with hundreds of thousands more working and living in the tsunamis hazard zones. Given the relative infrequency of tsunamis, exercises are a valuable tool to test communications, evaluate preparedness and raise awareness. Exercises in the Caribbean are conducted under the framework of the UNESCO IOC Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) and the US National Tsunami Hazard Mitigation Program. On March 23, 2011, 34 countries and territories participated in the first CARIBE WAVE/LANTEX regional tsunami exercise, while in the second exercise on March 20, 2013 a total of 45 countries and territories participated. 481 organizations (almost 200 more than in 2011) also registered to receive the bulletins issued by the Pacific Tsunami Warning Center (PTWC), West Coast and Alaska Tsunami Warning Center and/or the Puerto Rico

    2011-12-01

    In May 2010 the CARIBIC instrument container (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container; www.caribic-atmospheric.com) was upgraded to include a new high resolution air sampler, HIRES. This new sampler consists of 88 1L stainless steel sampling flasks, supplementing the existing 2 units with 14 2.5L glass flasks each, increasing the CARIBIC sampling capacity to 116 whole air samples collected using a single pumping unit having two metal bellow pumps in series. The CARIBIC project involves the monthly deployment of a fully automated instrument container equipped to make atmospheric measurements from aboard a commercial airliner, and has operated since 2005 onboard a Lufthansa Airbus 340-600. Measurements from the container include in-situ trace gas and aerosol analyses and the collection of aerosol and whole air samples for post-flight laboratory analysis. Measurements made from the sampling flasks include greenhouse gas (GHG) and nonmethane hydrocarbon (NMHC) analysis. The first deployment of HIRES for a CARIBIC flight was in June 2010, and it has been in routine monthly operation since, making a total of 1188 HIRES air samples collected as of July 2011 (from a total of 1566 CARIBIC air samples). The ability of CARIBIC to observe the atmosphere at aircraft cruising altitudes (9-12 km) provides the opportunity to regularly measure the composition of the upper troposphere/lowermost stratosphere (UT/LS), and increased sampling resolution has provided invaluable long-term observations of GHG and NMHC gradients across the tropopause which are unique to CARIBIC. Here we provide a detailed description of the collection system itself, and give first results from the inaugural year of HIRES, which include detailed observations of pollution plumes over eastern Asia, tropical convection over continental Africa, and trace gas gradients in the tropopause at high northern latitudes.

    The particle number size distribution is an important parameter to characterize the atmospheric aerosol and its influence on the Earth's climate. Here we describe a new optical particle size spectrometer (OPSS) for measurements of the accumulation mode particle number size distribution in the tropopause region on board a passenger aircraft (IAGOS-CARIBIC observatory: In-service Aircraft for a Global Observing System - Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrument Container). A modified KS93 particle sensor from RION Co., Ltd., together with a new airflow system and a dedicated data acquisition system, is the key component of the CARIBIC OPSS. The instrument records individual particle pulse signal curves in the particle size range 130-1110 nm diameter (for a particle refractive index of 1.47-i0.006) together with a time stamp and thus allows the post-flight choice of the time resolution and the size distribution bin width. The CARIBIC OPSS has a 50 % particle detection diameter of 152 nm and a maximum asymptotic counting efficiency of 98 %. The instrument's measurement performance shows no pressure dependency and no particle coincidence for free tropospheric conditions. The size response function of the CARIBIC OPSS was obtained by a polystyrene latex calibration in combination with model calculations. Particle number size distributions measured with the new OPSS in the lowermost stratosphere agreed within a factor of 2 in concentration with balloon-borne measurements over western North America. Since June 2010 the CARIBIC OPSS is deployed once per month in the IAGOS-CARIBIC observatory.

  20. Observations of the 2008 Kasatochi volcanic SO2 plume by CARIBIC aircraft DOAS and the GOME-2 satellite

    2010-05-01

    Full Text Available The 2008 Kasatochi volcanic eruption emitted ≈1.5–2.5 Tg SO2 into the upper troposphere and lower stratosphere. Parts of the main volcanic plume (gases and particles reached central Europe a week after the eruption and were detected there by the CARIBIC (Civil Aircraft for Regular investigation of the Atmosphere based on an Instrument Container flying observatory. The plume was also observed by the GOME-2 satellite instrument, only a few hours after the CARIBIC aircraft had crossed the plume, thus giving a unique opportunity to compare results. Trajectories and local wind speeds are investigated in detail using the GOME-2 and CARIBIC observations for better comparison of the results from these two observational systems. A comparison of the satellite spatial pattern with the local observations of the wind speed and the trajectory model TRAJKS showed a slight discrepancy, which has to be considered for satellite validation. Hence, it appears that detailed analyses of wind speeds are required. Emitted and secondary particles, partly measured and sampled by the CARIBIC in situ instruments, affected the DOAS SO2 measurements, of both CARIBIC and GOME-2. Overall GOME-2 and the CARIBIC SO2 measurements agree very well. The major uncertainties remain the actual wind speed needed to properly correct for the advection of the plume between the different overpass times and effects of aerosols on DOAS retrievals. The good agreement can be seen as validation for both GOME-2 and CARIBIC DOAS observations.

  8. CARIBIC observations of gaseous mercury in the upper troposphere and lower stratosphere

    2013-04-01

    Full Text Available A unique set of gaseous mercury measurements in the upper troposphere and lower stratosphere (UT/LS has been obtained during the monthly CARIBIC (www.caribic-atmospheric.com flights since May 2005. The passenger Airbus 340-600 of Lufthansa covered routes to the Far East, North America, India, and the southern hemisphere. The accompanying measurements of CO, O3, NOy, H2O, aerosols, halocarbons, hydrocarbons, greenhouse gases, and several other parameters as well as backward trajectories enable a detailed analysis of these measurements. Speciation tests have shown that the CARIBIC measurements represent a good approximation of total gaseous mercury (TGM concentrations. Above the tropopause TGM always decrease with increasing potential vorticity (PV and O3 which implies its conversion to particle bound mercury. The observation of the lowest TGM concentrations at the highest particle concentrations in the stratosphere provides further evidence for such conversion. We will show how a seasonally dependent conversion rate could be derived using concomitantly measured SF6 mixing ratios as a timer. Tropospheric mercury data suggest the existence of a decreasing trend in the northern hemisphere whose size is comparable with the trend derived from long-term measurements by ship cruises, at Cape Point (South Africa and Mace Head (Ireland.

    2011-06-01

    Full Text Available The Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container (CARIBIC project investigates physical and chemical processes in the Earth's atmosphere using a Lufthansa Airbus long-distance passenger aircraft. After the beginning of the explosive eruption of the Eyjafjallajökull volcano on Iceland on 14 April 2010, the first CARIBIC volcano-specific measurement flight was carried out over the Baltic Sea and Southern Sweden on 20 April. Two more flights followed: one over Ireland and the Irish Sea on 16 May and the other over the Norwegian Sea on 19 May 2010. During these three special mission flights the CARIBIC container proved its merits as a versatile and comprehensive flying laboratory. The elemental composition of particles collected over the Baltic Sea during the first flight (20 April indicated the presence of volcanic ash. Over Northern Ireland and the Irish Sea (16 May, the DOAS system detected SO2 and BrO co-located with volcanic ash particles that increased the aerosol optical depth. Over the Norwegian Sea (19 May, the optical particle counter detected a strong increase of particles larger than 400 nm diameter in a region where ash clouds were predicted by aerosol dispersion models. Aerosol particle samples collected over the Irish Sea and the Norwegian Sea showed large relative enhancements of the elements silicon, iron, titanium and calcium. Non-methane hydrocarbon concentrations in whole air samples collected on 16 May and 19 May 2010 showed a pattern of removal of several hydrocarbons that is typical for chlorine chemistry in the plumes. Comparisons of measured ash concentrations and simulations with the FLEXPART dispersion model demonstrate the difficulty of detailed volcanic ash dispersion modelling due to the large variability of the volcanic plume sources, extent and patchiness as well as the thin ash layers formed in the volcanic plumes.

    The CARIBIC project (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) involves the monthly deployment of an instrument container equipped to make atmospheric measurements from onboard a long-range commercial airliner. Since December 2004, flights for the second phase of CARIBIC have been aboard a Lufthansa Airbus A340-600 traveling between Frankfurt, Germany and destinations in Asia, North America and South America. The instrument package housed in the container is fully automated and during each flight carries out a variety of real-time trace gas and aerosol measurements, and also collects 28 air samples, which are analyzed upon return to the laboratory. Routine measurements made from the sampling flasks include greenhouse gases, nonmethane hydrocarbons (NMHCs), and halocarbons; results of air sample analysis form the basis for the data discussed here. While the majority of CARIBIC samples represent background free tropospheric air and air representative of the upper troposphere/lower stratosphere, the aircraft also, less frequently, encounters air parcels influenced by more recent emissions. Here we present a case study of a round-trip flight between Frankfurt and Toronto, Canada during September 2007. During this flight, different air masses of unique origin were encountered; a number of samples were influenced by transport from the Gulf of Mexico, while others had source regions in Central and Southeast Asia. Samples from the Gulf of Mexico exhibited enhancements in C3-C6 alkanes, as well as a number of halogenated compounds with oceanic sources, such as methyl iodide and bromoform, while Asian samples had enhanced levels of combustion products (CO, acetylene, benzene) and anthropogenic halocarbons (methlyene chloride, chloroform, perchloroethylene). Additionally, a number of samples also showed stratospheric influence, and these samples were characterized by relatively depleted levels of many of the compounds

    Full Text Available From the new approaches in social studies of science and technology concerned with the analysis of sites where science is developed and how it circulates, I am interested to observe the Caribbean as an island-center in the tropical agronomic knowledge development. For this, I study how the scientific steps were formulated to eradicate the plagues that currently affect more intensely coconut plantations in the Caribbean and Latin America, called Lethal Yellowing Disease of Coconut, which has destroyed the industry crops in many areas. The epidemic first appeared in the nineteenth century in the Caribbean Antilles, which forced local scientists to develop a database of global knowledge. In particular, I observe the process in Cuba from scientific discussions generated at the Royal Academy of Medical Sciences, Physical and Natural Sciences of Havana, as well as the entry of U.S. scientists in the new imperial context of early twentieth century, who expanded their field of study throughout the English and Spanish Caribbean through the exchange of ideas and experiences.

    Full Text Available Inter-comparison of results from two kinds of aerosol systems in the CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container passenger aircraft based observatory, operating during intercontinental flights at 9–12 km altitude, is presented. Aerosol from the lowermost stratosphere (LMS, the extra-tropical upper troposphere (UT and the tropical mid troposphere (MT were investigated. Aerosol particle volume concentration measured with an optical particle counter (OPC is compared with analytical results of the sum of masses of all major and several minor constituents from aerosol samples collected with an impactor. Analyses were undertaken with accelerator-based methods particle-induced X-ray emission (PIXE and particle elastic scattering analysis (PESA. Data from 48 flights during one year are used, leading to a total of 106 individual comparisons. The ratios of the particle volume from the OPC and the total mass from the analyses were in 84% within a relatively narrow interval. Data points outside this interval are connected with inlet-related effects in clouds, large variability in aerosol composition, particle size distribution effects and some cases of non-ideal sampling. Overall, the comparison of these two CARIBIC measurements based on vastly different methods show good agreement, implying that the chemical and size information can be combined in studies of the MT/UT/LMS aerosol.

    CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) is a long-term atmospheric measurement program based on the use of a comprehensive scientific instrument package aboard a commercial passenger aircraft. In addition to real-time measurements, whole air sampling is performed regularly at cruising altitudes in the tropical middle troposphere and the extra-tropical UT/LS region. Air samples are analyzed for greenhouse gases, NMHCs, halocarbons, and trace gas isotopic composition. The routinely performed greenhouse gas analysis comprises gas chromatography measurements of CO2, CH4, N2O and SF6. The air sampling procedure, the GC system and its performance are described. Comparisons with similar systems employed in other laboratories and a comparison with results from a CO2 in-situ analyzer that is also part of the CARIBIC instrumentation are shown. In addition, the time series of CO2, obtained from the collection of 684 samples at latitudes between 30° N and 56° N on 21 round trips out of Germany to different destinations in Asia between November 2005 and October 2008, is presented. A time shift in the seasonal cycle of about one month was observed between the upper troposphere and the tropopause region. For two sets of return flights from Germany to the Philippines the relationship between the four greenhouse gases is briefly discussed.

    An airfreight container equipped with automated analysers was deployed onboard of a passenger Boeing 767 ER of LTU International Airways during regular long-distance flights. From November 1997 to the decommissioning of the aircraft in May 2002, 86 flights were carried out on routes to Southern India, the Caribbean, and Southern Africa providing data on distribution of O3, CO, aerosols (nuclei > 4, 12, 18 nm) in the tropopause region from continuous measurements and of CO2, H2, CO, their isotopic composition, halocarbons, hydrocarbons, N2O, CH4, SF6, and elemental aerosol composition from analyses of samples. Based on this experience a totally new and more powerful CARIBIC system has been developed and put into operation, based on a sophisticated inlet system and a new container with a largely extended instrumentation. The inlet system is designed for sampling of small aerosol particles. In addition, it contains 3 separate probes to sample air for measurements of trace gases (heated and PFA coated), total and gaseous water (heated electropolished stainless steel). It also accommodates 3 telescopes of a mini differential optical absorption spectrometer (MAX-DOAS) and a camera for information about clouds. The current instrument package comprises analysers for total and gaseous H2O, O3, NO and NOy, CO, CO2, O2, Hg, and three condensation nuclei counters for particles larger than 4, 12, and 18 nm. A proton transfer mass spectrometer (PTR-MS) and an optical particle counter are installed to measure selected organic compounds and the particle size distributions, respectively. Samples of aerosol, of air (glass canisters) and of VOC and OVOC (adsorption tubes) are taken as well. This allows for a broad spectrum of laboratory analyses. The new CARIBIC system onboard a new passenger Lufthansa Airbus 340-600 has been in operation since December 2004 on a regular long-distance routes from Frankfurt to Santiago de Chile or Manila. The system is planned to flight monthly for a

    For 200 years, Pikes Peak has been a symbol of America's Western Frontier--a beacon that drew prospectors during the great 1859-60 Gold Rush to the 'Pikes Peak country,' the scenic destination for hundreds of thousands of visitors each year, and an enduring source of pride for cities in the region, the State of Colorado, and the Nation. November 2006 marks the 200th anniversary of the Zebulon M. Pike expedition's first sighting of what has become one of the world's most famous mountains--Pikes Peak. In the decades following that sighting, Pikes Peak became symbolic of America's Western Frontier, embodying the spirit of Native Americans, early explorers, trappers, and traders who traversed the vast uncharted wilderness of the Western Great Plains and the Southern Rocky Mountains.

Esto ha implicado el reconocimiento de derechos y estatutos especiales a diversas poblaciones y sus territorios, entre ellas a la población isleña-raizal del Archipiélago de San Andrés, Providencia y Santa Catalina. Este reconocimiento ha ocasionado que la población raizal reelabore y reinvente los discursos sobre su identidad, a la vez que ha recrudecido el conflicto entre algunos sectores de esta población y el Estado colombiano. Este artículo analiza los discursos y elementos que construyen la identidad isleña-raizal desde las propias representaciones de la población, con el fin de explorar los valores que conforman dicha identidad en la cotidianidad interculrural propia de la región Caribe.

    Based on a case-study of the nickel smelter in Norilsk (Siberia), the retrieval of trace gas fluxes using airborne remote sensing is discussed. A DOAS system onboard an Airbus 340 detected large amounts of SO2 and NO2 near Norilsk during a regular passenger flight within the CARIBIC project. The remote sensing data were combined with ECMWF wind data to estimate the SO2 output of the Norilsk industrial complex to be around 1 Mt per year, which is in agreement with independent estimates. This value is compared to results using data from satellite remote sensing (GOME, OMI). The validity of the assumptions underlying our estimate is discussed, including the adaptation of this method to other gases and sources like the NO2 emissions of large industries or cities.

    2009-10-01

    Full Text Available The CARIBIC project (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container is a long-term monitoring program making regular atmospheric measurements from an instrument container installed monthly aboard a passenger aircraft. Typical cruising altitudes of the aircraft allow for the study of the free troposphere and the extra-tropical upper troposphere as well as the lowermost stratosphere. CARIBIC measurements include a number of real time analyses as well as the collection of aerosol and whole air samples. These whole air samples are analyzed post-flight for a suite of trace gases, which includes non-methane hydrocarbons (NMHC.

    The NMHC measurement system and its analytical performance are described here. Precision was found to vary slightly by compound, and is less than 2% for the C2–C6 alkanes and ethyne, and between 1 and 6% for C7–C8 alkanes and aromatic compounds. Preliminary results from participation in a Global Atmospheric Watch (WMO VOC audit indicate accuracies within the precision of the system. Limits of detection are 1 pptv for most compounds, and up to 3 pptv for some aromatics. These are sufficiently low to measure mixing ratios typically observed in the upper troposphere and lowermost stratosphere for the longer-lived NMHC, however, in air samples from these regions many of the compounds with shorter lifetimes (<5 d were frequently below the detection limit. Observed NMHC concentrations span many orders of magnitude, dependent on atmospheric region and air mass history, with concentrations typically decreasing with shorter chemical lifetimes.

    Full Text Available A DOAS (Differential Optical Absorption Spectroscopy instrument was implemented and operated onboard a long-distance passenger aircraft within the framework of the CARIBIC project (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container. The instrument was designed to keep weight, size and power consumption low and to comply with civil aviation regulations. It records spectra of scattered light from three viewing directions (nadir, 10° above and below horizon using a miniaturized telescope system. The telescopes are integrated in the main pylon of the inlet system which is mounted at the belly of the aircraft. Fibre bundles transmit light from the telescopes to spectrograph-detector units inside the DOAS container instrument. The latter is part of the removable CARIBIC instrument container, which is installed monthly on the aircraft for a series of measurement flights.

    During 30 flight operations within three years, measurements of HCHO, HONO, NO2, BrO, O3 and the oxygen dimer O4 were conducted. All of these trace gases except BrO could be analysed with a 30 s time resolution. HONO was detected for the first time in a deep convective cloud over central Asia, while BrO, NO2 and O3 could be observed in tropopause fold regions. Biomass burning signatures over South America could be seen and measurements during ascent and descent provided information on boundary layer trace gas profiles (e.g. NO2 or HCHO.

    Full Text Available El Caribe mexicano atrae visitantes de regiones distintas en diferentes épocas del año. A los prestadores de servicios turísticos les resulta difícil conocer y separar las preferencias de actividades que realizan los visitantes de cada país. Arriban visitantes mexicanos y extranjeros, las preferencias de estos últimos en relación a la demanda de servicios son diferentes. Contrario a lo que se conocía, el estudio de mercado determinó que la demanda mexicana representa un mercado importante en marcadas épocas del año. Se calcula que cada año alrededor de dos millones de turistas nacionales arriban a la Riviera y Costa Maya en la región norte de Quintana Roo. Conocer las preferencias de consumo de los diferentes segmentos de turistas y la forma en que evalúan la posibilidad de demandar los servicios turísticos da la pauta para ofrecérselos en forma diferenciada y adecuada a cada segmento y en relación a cada una de las diversas actividades turísticas que realizan, entre ellas el ecoturismo de la cual poco se conoce en esta región del país.

    Full Text Available Durante su primer gobierno (1870-1877, el Presidente Antonio Guzmán Blanco desarrolló un programa que aspiraba a centralizar política y económicamente a Venezuela. Una de las disposiciones aprobadas fue el cierre de los puertos de Maracaibo y La Vela, para las operaciones de importación y exportación realizadas desde los Andes venezolanos y colombianos, a través del Caribe. Estas funciones fueron transferidas al distante Puerto Cabello. Gran parte del occidente del país fue afectado por esta medida que no consideraba la larga tradición histórica de centros económicos que por centurias habían liderado las actividades agroexportadoras de sus respectivosámbitos comerciales. La medida no sólo perjudicó los intereses de la región histórica del Lago y de Coro, favoreció a grupos económicos rivales establecidos en la región norcentral, asociados con el presidente de la república. En el caso particular del Zulia, el cierre del puerto de Maracaibo afectó a financistas, pequeños y grandes comerciantes, transportistas, navegantes, marineros, productores y diferentes colectivos del estado; otros sectores perjudicados fueron los comerciantes vinculados con esta actividad en Colombia y Curazao.

    Full Text Available Este estudio descriptivo, con enfoque cuantitativo y diseño transversal buscó revisar algunas de las habilidades de prelectura que tienen los estudiantes de transición (preescolar de estratos 1 y 2 de la región caribe colombiana como aspectos fundamentales de la preparación escolar temprana. Se utilizaron diversos instrumentos: IDEL, PLS 4, NEPSY II y BOHEM-3. Las habilidades evaluadas fueron: comprensión auditiva, conciencia fonológica, velocidad de nominación de letras, nombramiento rápido de categorías verbales y conceptos básicos de relación. Se encontró que en conceptos básicos de relación y comprensión auditiva, los resultados de los niños son buenos, ya que más del 70% de ellos están con un nivel acorde a su edad o por encima de esta; en las demás habilidades, las puntuaciones están en un gran porcentaje por debajo del nivel de edad. Esto da cuenta del impacto del contexto escolar, socioeconómico y socio demográfico en el logro académico.

This species has a wide distribution in tropical and subtropical zones of the Eastern Atlantic Ocean, but in the Western Atlantic there is only a doubtful record for Venezuela and Brazil. This species presents all typical features of the genus Palisada, being characterized by turf-like growth, the presence of arcuate and decumbent branches with erect branches disposed unilaterally. In the present paper we provide a detailed description of the vegetative and tetrasporangial structures. The geographical distribution of P. perforata in the Western Atlantic ocean was amplified with a new record in the Mexican Caribbean.

    The Loma Caribe peridotite body is mainly composed of serpentinized spinel harzburgites and lherzolites and minor orthopyroxene-bearing dunites and dunites. Modal proportions, mineral and whole-rock major and trace element compositions generally coincide with those of abyssal mantle rocks from mid-ocean ridges for the lherzolites, and refractory supra-subduction peridotites for the harzburgites and dunites. The clinopyroxene-bearing harzburgites have intermediate compositions that overlap with those of residual mantle from both these settings. Major elements in the peridotites were mostly undisturbed by serpentinization and/or seafloor weathering whereas light rare earth elements (LREE) and large ion lithophile elements (LILE) were enriched by syn- and/or post-melting interaction with fluids/melts. Major element variations indicate that protoliths of the Loma Caribe peridotites mostly melted at 1-2 GPa and 1250 °C-1500 °C, as normal mid-ocean ridge and supra-subduction zone mantle. The MREE/HREE fractionations in both whole rocks and clinopyroxene can be explained by initial low (5%-6%) fractional melting of a garnet lherzolite source followed by variable (5%-20%) melting in the spinel stability field. The lherzolites and clinopyroxene-bearing harzburgites are residues of increasing melting triggered by increasing addition of slab fluids to a spinel peridotite source, while melting of the harzburgite protoliths was likely the result of focused flux of slab hydrous melts. The dunites and orthopyroxene-bearing dunites are products of pyroxene dissolution in residual peridotites caused by reaction with two different subduction-related melts, probably the parental magmas of Early Cretaceous low-Ti island arc tholeiites (IAT) and boninites from Central Hispaniola, respectively. We conclude that the geochemical heterogeneity of the Loma Caribe peridotites records shifting conditions of melting during the development of subduction beneath the incipient Greater Antilles

    The Loma Caribe peridotite body is mainly composed of serpentinized spinel harzburgite and lherzolite and minor (Opx-bearing) dunite. Modal proportions, mineral and whole-rock major and trace element compositions generally coincide with those of abyssal mantle rocks from mid-ocean ridges for lherzolite and refractory supra-subduction peridotites for harzburgite and (Opx-) dunite. Cpx-bearing harzburgite has intermediate compositions that overlap those of residual mantle from both these settings. Major elements in peridotite were mostly undisturbed by serpentinization and/or seafloor weathering whereas LREE and LILE were enriched by syn- and/or post-melting interaction with fluids/melts. Major element variations support that protoliths of Loma Caribe peridotite mostly melted at 1-2 GPa and 1300-1500 °C, as normal mid-ocean ridge and supra-subduction zone mantle. MREE/HREE fractionations in whole-rocks and clinopyroxene can be explained by initial low (5-6%) fractional melting of a garnet lherzolite source followed by variable (5-20%) melting in the spinel stability field. Lherzolite and Cpx-harzburgite are residues of increasing melting triggered by increasing addition of fluids to a spinel peridotite source, while melting of the harzburgite protolith was likely promoted by focused flux of hydrous melts. Dunite and Opx-bearing dunite are products of pyroxene dissolution in residual peridotite caused by reaction with two different subduction-related melts, likely the parental magmas of Early Cretaceous low-Ti IAT and boninite from Central Hispaniola, respectively. We propose that the geochemical heterogeneity of Loma Caribe peridotite records shifting conditions of melting during the development of subduction beneath the incipient Greater Antilles paleo-island arc in the Early Cretaceous. The common presence in the Caribbean realm of oceanic mantle rocks related to subduction indicates that most peri-Caribbean ophiolitic bodies are not fragments of an oceanic

    Full Text Available La localidad de Sheshatshiu, en la península de Québec/Labrador, es uno de los asentamientos del pueblo Innu impulsados por el gobierno canadiense en los 1950s y 1960s. A pesar de la crisis alimentaria que la sedentarización forzada produjo, el caribú sigue constituyendo una parte importante de la dieta y la cultura Innu. El objetivo de este trabajo es mostrar una estrategia de modelización de la distribución de caribú en Sheshatshiu. La metodología seleccionada incluye tres pasos. El primer paso de modelización es el diseño de una base de datos con la información de distribución obtenida a partir de una encuesta en la que se relevaron 30 casas aleatoriamente y un subsiguiente muestreo "bola de nieve". Luego, se usa el programa UCINET para determinar clusterización, conectividad y centralidad. El tercer y último paso es determinar el alcance la distribución de caribú a partir del análisis de los procedimientos previos.The town of Sheshatshiu, located in the Quebec-Labrador peninsula, is one of the settlements created by the Canadian government in the 1950s and 1960s. In spite of the nutritional crisis that the forced sedentarization produced, caribou is still an important part of the Innu diet and culture. The goal of this paper is to show a modeling strategy of the caribou distribution in Sheshatshiu. The selected methodology includes three steps. The first modeling step is the design of a database to store the distribution information obtained from a random survey of 30 households and a subsequent snowball survey. The second step is to determine the clusterization, connectivity and centrality measures, using UCINET software. The third and last step is establishing the scope of caribou distribution using the previous procedures.

    Full Text Available Objetivo. Determinar la distribución y afinidades biogeográficas de los galateoideos de aguas colombianas con base en la literatura y muestras recolectadas durante expediciones realizadas entre 1999 y 2002. Materiales y métodos. Se recolectaron ejemplares en 100 estaciones entre 20 y 550 m de profundidad en el Caribe y Pacífico colombiano. El material recolectado, junto con la información geográfica existente en literatura para las especies conocidas para Colombia se emplearon para realizar mapas de distribución, los cuales se compararon con el “Mapa de ecorregiones marinas del mundo”. Resultados. Se obtuvo la información geográfica para 3247 ejemplares recolectados de 18 especies de los géneros Agononida, Anomoeomunida, Munida, Munidoposis y Pleuroncodes, y se complementó con la obtenida a partir de la literatura para las 40 especies de la superfamilia con presencia conocida en aguas colombianas. Se generaron cinco grupos principales de distribución: especies restringidas al Caribe, al Caribe y Atlántico occidental, Anfiatlánticas, restringidas al Pacífico oriental y Anfiamericanas. Se encontró que el 53 % de las especies recolectadas en el Caribe se presentan también en la provincia Atlántico Norte Cálido-Templado, y para el Océano Pacífico la mayor afinidad se da con la provincia Pacífico Oriental Tropical. Conclusiones. Los galateoideos en aguas colombianas presentan ámbitos geográficos y batimétricos amplios, presentándose simpatría entre algunas especies. Las de aguas someras presentan mayores restricciones que aquellas de distribución en aguas profundas. Los mecanismos de distribución de las especies corresponden con el ciclo de vida de cada una y las corrientes predominantes en las provincias.

    Nitrogen oxide (NO and NOy) measurements were performed onboard an in-service aircraft within the framework of CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container). A total of 330 flights were completed from May 2005 through April 2013 between Frankfurt/Germany and destination airports in Canada, the USA, Brazil, Venezuela, Chile, Argentina, Colombia, South Africa, China, South Korea, Japan, India, Thailand, and the Philippines. Different regions show differing NO and NOy mixing ratios. In the mid-latitudes, observed NOy and NO generally shows clear seasonal cycles in the upper troposphere with a maximum in summer and a minimum in winter. Mean NOy mixing ratios vary between 1.36 nmol/mol in summer and 0.27 nmol/mol in winter. Mean NO mixing ratios range between 0.05 nmol/mol and 0.22 nmol/mol. Regions south of 40°N show no consistent seasonal dependence. Based on CO observations, low, median and high CO air masses were defined. According to this classification, more data was obtained in high CO air masses in the regions south of 40°N compared to the midlatitudes. This indicates that boundary layer emissions are more important in these regions. In general, NOy mixing ratios are highest when measured in high CO air masses. This dataset is one of the most comprehensive NO and NOy dataset available today for the upper troposphere and is therefore highly suitable for the validation of atmosphere-chemistry-models.

Ello ha posibilitado el rescate y análisis de un creciente e importante corpus de obras que continuamente se actualiza con nuevas puestas en escena y enfoques. Una línea de investigación valiosa al respecto ha sido la de intentar sistematizar, desde múltiples métodos y teorías, todo el repertorio encontrado. Los estudios de Costa Palamides y Elina Miranda, por mencionar algunos de los más conocidos, son valiosos aportes a este propósito. En este marco se inserta el presente trabajo que, partiendo de estudios anteriores y del rastreo de nuevas producciones dramáticas, aspira contribuir a la actualización y sistematización del corpus caribeño existente, así como revelar nuevas tendencias. Nos enfocamos especialmente en las obras de las Antillas hispanas, puestas en relación con las producidas en otras áreas del Caribe.

    The research project CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container, phase II) is designed to conduct regular, long-term and detailed observations of the free troposphere and UT/LS regions where passenger aircraft happen to cruise. A fully-automated measurement container (1.5 tons) was equipped onboard an Airbus 340-600 operated by Lufthansa Airlines during regular passenger flights to conduct real time trace gas and aerosol measurements and to collect aerosol and air samples on a near monthly basis. During May 2005 - March 2008, CARIBIC observations have been performed along the flight tracks of Frankfurt-Guangzhou-Manila. Data have been collected in the upper troposphere during a total of 81 flights over the region between South China and the Philippines. Carbon monoxide was used an indicator to identify the pollution events and to access the regional impacts of fossil fuel burning and biomass/biofuel burning on upper tropospheric air. Five regions, i.e. Northeast Asia, South China, Indochina Peninsula, India and Indonesia/Philippines, are identified as the major source regions to be related to the observed pollution events. The characteristics of the events from these regions are investigated. The contributions of different source categories are also estimated.

Ésto se realizó mediante un análisis de similitud de áreas, y bajo un enfoque panbiogeográfico. Se encontró que las áreas más afines actualmente con la flora del “El Ceibal” son los bosques húmedos y secos centroamericanos, bosque húmedo de Urabá-Magdalena y los valles interandinos de Colombia. En cuanto a la panbiogeografía, se obtuvieron cuatro trazos generalizados, que coinciden en la conexión con las áreas centroamericanas, la Serranía del Perijá, Guajira, la costa Caribe venezolana y los valles interandinos de Colombia. También se evidencia la relación, no muy fuertemente respaldada, del bosque seco del Caribe colombiano con áreas del centro y sur de Suramérica. Los trazos coinciden con los obtenidos por numerosos trabajos, especialmente sobre la biota mesoamericana. Estas
    relaciones evidencian el carácter caribeño de la flora de la Hacienda “El Ceibal” y su complejidad biogeográfica.

Average SO2 and BrO mixing ratios of ≈40 ppb and ≈5 ppt respectively are retrieved inside the plume. The BrO to SO2 ratio retrieved from the CARIBIC observation is ≈1.3×10−4. Both SO2 and BrO observations agree well with simultaneous satellite (GOME-2 observations. SO2 column densities retrieved from satellite observations are often used as an indicator for volcanic ash. As the CARIBIC O4 column densities changed rapidly during the plume observation, we conclude that the aerosol and the SO2 plume are collocated. For SO2 some additional information on the local distribution can be derived from a comparison of forward and back scan GOME-2 data. More details on the local plume size and position are retrieved by combining CARIBIC and GOME-2 data.

    Full Text Available This paper analyses and quantifies the relative level of risk in a geographical area that is vulnerable to natural phenomena and with a high proportion of its population in a situation of residential poverty. We deduce that the hazard in the area, composed of nine Central American and Caribbean countries, is significantly higher than the world average. The first aspect is covered in the sections Population at risk and Natural phenomena, which analyse the "study area". The second aspect is covered by Poverty in the "study area", various analyses of the physical situation in the target area, inhabited by almost 160 million people. Contrasted information is used as a basis for the concepts underpinning the extraordinary presence and seriousness of the socio-natural phenomena in this area. The interrelationship between th degree of vulnerability and poverty leads to the conclusion that these are the primary causes of disaster-related destruction, which in a 33 year period (1972 to 2005 has left an annual average of 20,000 human lives lost, 250,000 directly affected and approximately ten billion dollars in material damage.El trabajo pretende el estudio y cuantificación del riesgo relativo en una geografía física propensa a los fenómenos naturales y con una alta proporción de población en situación de pobreza habitacional, del que se deduce que el riesgo en la zona conformada por nueve países –de Centroamérica y el Caribe- es extraordinariamente superior a la media mundial. Del primer aspecto se ocupan los apartados relativos a delimitar el 'Área de Estudio': fenómenos naturales y población bajo riesgo. El segundo aspecto se aborda estudiando la situación material objetiva en la que se alojan y viven casi 160 millones de habitantes: Pobreza en el 'Área de Estudio'.

    More than 450 air samples that were collected in the upper troposphere - lower stratosphere (UTLS) region by the CARIBIC aircraft (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) have been analyzed for molecular hydrogen (H2) mixing ratios (χ(H2)) and H2 isotopic composition (deuterium content, δD). More than 120 of the analyzed samples contained air from the lowermost stratosphere (LMS). These show that χ(H2) does not vary appreciably with O3-derived height above the thermal tropopause (TP), whereas δD does increase with height. The isotope enrichment is caused by H2 production and destruction processes that enrich the stratospheric H2 reservoir in deuterium (D); the exact shapes of the profiles are mainly determined by mixing of stratospheric with tropospheric air. Tight negative correlations are found between δD and the mixing ratios of methane (χ(CH4)) and nitrous oxide (χ(N2O)), as a result of the relatively long lifetimes of these three species. The correlations are described by δD[‰]=-0.35 · χ(CH4)[ppb]+768 and δD[‰]=-1.90· χ(N2O)[ppb]+745. These correlations are similar to previously published results and likely hold globally for the LMS. Samples that were collected from the Indian subcontinent up to 40° N before, during and after the summer monsoon season show no significant seasonal change in χ(H2), but δD is up to 12.3‰ lower in the July, August and September monsoon samples. This δD decrease is correlated with the χ(CH4) increase in these samples. The significant correlation with χ(CH4) and the absence of a perceptible χ(H2) increase that accompanies the δD decrease indicates that microbial production of very D-depleted H2 in the wet season may contribute to this phenomenon. Some of the samples have very high χ(H2) and very low δD values, which indicates a pollution effect. Aircraft engine exhaust plumes are a suspected cause, since the effect mostly occurs in samples

    The CARIBIC project (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container, www.caribic-atmospheric.com) involves the monthly deployment of an instrument container equipped to make atmospheric measurements from onboard a long-range commercial airliner. Since December 2004, flights for the second phase of CARIBIC have been aboard a Lufthansa Airbus A340-600 traveling between Frankfurt, Germany and destinations in Asia, North America and South America. The instrument package housed in the container (1.5 ton) is fully automated and during each monthly set of flights carries out a variety of real-time trace gas and aerosol measurements, and also collects 28 air samples, which are analyzed upon return to the laboratory. Routine measurements made from the sampling flasks include non-methane hydrocarbon (NMHC) analysis, and these measurements provide the basis for the data presented here. Between April and September of 2008, the container was deployed monthly on two sequential roundtrip flights between Frankfurt and Chennai, India. To achieve greater resolution, air samples were collected only on the first of the roundtrip flights, with 14 samples collected on the flight to Chennai and 14 collected on the return. These flights provided the opportunity to study the composition of the upper troposphere in this region during the Asian summer monsoon period (typically June-September), which is characterized by anticyclonic circulation in the upper troposphere coupled with deep convection. Samples collected during the monsoon period exhibit elevated levels of NMHCs relative to samples collected outside of the monsoon period, with enhancements in ethyne and benzene being more substantial than enhancements in the alkanes. Enhanced mixing ratios are observed between 15N and 40N, and correspond to enhancements in other trace gases, namely methane and CO. Ethyne in particular is strongly correlated with both methane and CO in this region

    Full Text Available La captura acompañante, es decir, individuos que sin ser objetivo de las pesquerías son capturados por las artes de pesca, se ha convertido en un tema de preocupación mundial debido al impacto que su extracción significa para los ecosistemas. En el mar Caribe de Colombia opera una flota de pesca de arrastre dirigida al camarón que registra elevados niveles de captura acompañante. Las evaluaciones de las capturas de esta flota se han concentrado en las especies de peces principalmente y de invertebrados en menor grado, pero en la actualidad no existe un estudio que evalúe la composición taxonómica y brinde indicios sobre el efecto que tienen la pesca de arrastre en las comunidades de macroalgas, a pesar de que estas comunidades juegan un rol importante en la estructura y complejidad de los ecosistemas. Este estudio evaluó la composición taxonómica y biomasa de macroalgas registrada en muestreos a bordo de las flotas de arrastre de camarón en las zonas de pesca ubicadas al norte y sur del mar Caribe colombiano durante los meses de agosto, septiembre y octubre de 2004. Se obtuvo un total de 15 taxa de macroalgas en las dos zonas de pesca. El género más frecuente fue Sargassum, lo cual puede deberse a que su estrategia de vida pelágica y bentónica lo hace más vulnerable a la acción de las redes en los fondos. Las abundancias de algas fueron muy similares
    en ambas sitios de estudio. La biomasa de macroalgas registradas en cada lance fue mucho menor que la registrada de camarones y descartes. La evidencia que presenta este estudio sobre la existencia de macroalgas en la captura acompañante de la flota de arrastre de camarón y la acción prolongada de esta pesquería en el mar Caribe de Colombia, indican que es urgente implementar modificaciones en las redes para disminuir su efecto abrasivo sobre los fondos.

    El caracol Pala, Strombus gigas (Strombidae, es de gran importancia ecológica y socioeconómica en el área caribeña colombiana. Sin embargo, es una especie catalogada como “vulnerable” y existe muy poca información referente a las especies bacterianas asociadas al caracol que puedan ser importantes para el desarrollo, manejo productivo y de seguridad acuícola de estos gastrópodos. En este trabajo, nosotros empleamos un estudio microbiológico y molecular de la región intergénica entre los genes 16S y 23S rDNA, análisis del gen rDNA 16S y secuenciación, para analizar las bacterias asociadas al caracol Pala (S. gigas. La composición de bacterias cultivables asociadas fue evaluada por su capacidad para crecer en agar marino y en medios de cultivos selectivos. De un total de 28 muestras analizadas encontramos que el número de bacterias cultivadas en condiciones aerobias fue de alrededor 106 ufc mL-1 donde las bacterias pertenecientes a la familia Vibrionacea fueron las más abundantes, cerca de >105 ufc mL-1 . El análisis molecular de la región intergénica entre los genes 16S y 23S rDNA de las diferentes muestras, reveló una gran complejidad bacteriana asociada a S. gigas. Las secuencias de los amplificados del gen rDNA 16S identificó Pseudoalteromonas sp., Halomonas sp., Psycrobacter sp., Cobetia sp., Pseudomonas sp. y Vibrios sp. Nuestros resultados podrían sugerir un rol importante de estas bacterias como componentes de la comunidad asociada al S. gigas. Esta información puede complementar los estudios que se están implementando en los procesos para la conservación y repoblamiento de las poblaciones de S. gigas en Colombia.

    Full Text Available Las migraciones caribeñas han sido ampliamente documentadas, especialmente desde visiones económicas y demográficas que enfatizan los aspectos negativos que estas causan en individuos y sociedades. Sin embargo, desde las ciencias humanas se ha difundido el concepto de culturas migratorias para analizarlas . El eje central es que, más allá de un fenómeno de tipo económico, ligado a superpoblación y desempleo , la movilidad caribeña puede entenderse como una tradición cultural que se ha convertido en un modo de vida legitimado por generaciones de migrantes, permitiendo la viabilidad de estas sociedades. Este concepto supone la movilidad constante a manera de migraciones temporales utilizadas como estrategias económicas básicas, así como mecanismos socioculturales que facilitan y perpetúan esta práctica. Este seria el caso de los habitantes de Providencia y Santa Catalina en el territorio de habla inglesa en el Caribe colombiano, quienes poseen una larga historia de migraciones que continúan hasta hoy y que constituyen una forma de vida. Este documento resulta de investigaciones realizadas tanto en las islas como con migrantes en Bogotá, entre 2004 y 2011, en las cuales se abordaron diversos temas, incluyendo el papel de las migraciones en la vida de estos isleños, las memorias y las percepciones sobre las mismas.

Estas delimitaciones disciplinarias se han convertido en un obstáculo para el conocimiento e interpretación de las dinámicas que siguieron al impulso inicial de la colonización del litoral caribeño y la bien conocida fundación de los centros militares y administrativos.

    Jarrett, R. D.; Vandas, S.J.

    2006-01-01

    In the early evening of July 31, 1976, a large stationary thunderstorm released as much as 7.5 inches of rainfall in about an hour (about 12 inches in a few hours) in the upper reaches of the Big Thompson River drainage. This large amount of rainfall in such a short period of time produced a flash flood that caught residents and tourists by surprise. The immense volume of water that churned down the narrow Big Thompson Canyon scoured the river channel and destroyed everything in its path, including 418 homes, 52 businesses, numerous bridges, paved and unpaved roads, power and telephone lines, and many other structures. The tragedy claimed the lives of 144 people. Scores of other people narrowly escaped with their lives. The Big Thompson flood ranks among the deadliest of Colorado's recorded floods. It is one of several destructive floods in the United States that has shown the necessity of conducting research to determine the causes and effects of floods. The U.S. Geological Survey (USGS) conducts research and operates a Nationwide streamgage network to help understand and predict the magnitude and likelihood of large streamflow events such as the Big Thompson Flood. Such research and streamgage information are part of an ongoing USGS effort to reduce flood hazards and to increase public awareness.

    Analytical details for 13C and 18O isotope analyses of atmospheric CO2 in large air samples are given. The large air samples of nominally 300 L were collected during the passenger aircraft-based atmospheric chemistry research project CARIBIC and analyzed for a large number of trace gases and isotopic composition. In the laboratory, an ultra-pure and high efficiency extraction system and high-quality isotope ratio mass spectrometry were used. Because direct comparison with other laboratories was practically impossible, the extraction and measurement procedures were tested in considerable detail. Extracted CO2 was measured twice vs. two different working reference CO2 gases of different isotopic composition. The two data sets agree well and their distributions can be used to evaluate analytical errors due to isotope measurement, ion corrections, internal calibration consistency, etc. The calibration itself is based on NBS-19 and also verified using isotope analyses on pure CO2 gases (NIST Reference Materials (RMs) and NARCIS CO2 gases). The major problem encountered could be attributed to CO2-water exchange in the air sampling cylinders. This exchange decreased over the years. To exclude artefacts due to such isotopic exchange, the data were filtered to reject negative delta18O(CO2) values. Examples of the results are given. PMID:19219897

    Full Text Available Tropospheric sections of flights with the CARIBIC (Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrumented Container observatory from May 2005 until June 2013, are investigated for the occurrence of plumes with elevated Hg concentrations. Additional information on CO, CO2, CH4, NOy, O3, hydrocarbons, halocarbons, acetone and acetonitrile enable us to attribute the plumes to biomass burning, urban/industrial sources or a mixture of both. Altogether, 98 pollution plumes with elevated Hg concentrations and CO mixing ratios were encountered, and the Hg/CO emission ratios for 49 of them could be calculated. Most of the plumes were found over East Asia, in the African equatorial region, over South America and over Pakistan and India. The plumes encountered over equatorial Africa and over South America originate predominantly from biomass burning, as evidenced by the low Hg/CO emission ratios and elevated mixing ratios of acetonitrile, CH3Cl and particle concentrations. The backward trajectories point to the regions around the Rift Valley and the Amazon Basin, with its outskirts, as the source areas. The plumes encountered over East Asia and over Pakistan and India are predominantly of urban/industrial origin, sometimes mixed with products of biomass/biofuel burning. Backward trajectories point mostly to source areas in China and northern India. The Hg/CO2 and Hg/CH4 emission ratios for several plumes are also presented and discussed.

    Swimming is beneficial for persons with haemophilia (PWH) providing good maintenance of the cardiovascular and musculoskeletal system and improving many psychological characteristics. In the Desafío del Caribe Project, young PWH from Venezuela and Mexico took part in an open water competition in the Gulf of Mexico under a multidisciplinary team supervision. Eight severe haemophilia A, two moderate haemophilia A, one severe haemophilia B and two moderate haemophilia B subjects were included. Haematological, musculoskeletal and psychological evaluations were carried out before and during training for the competition. Training program included physical exercise routines and swimming practices that alternated between pools and open water. Swimmers had coverage with factor concentrates before pool and open water trainings. In physiatric evaluations, the Hemophilia Joint Health Score (HJHS) was used. The objective of the psychology area was to analyse self-esteem, precompetition anxiety, coping mechanisms and relaxation levels. The need of factor prophylaxis before intense trainings was confirmed. In the musculoskeletal system a decrease of elbow pain as well as an increase of muscle strength in the ankles were observed. In the psychological area significant differences between the first and second test in self-esteem levels, cognitive anxiety and group cohesion were found. PWH must be provided with orientation and encouragement to practice swimming regularly. High competition exercise must be supervised by a multidisciplinary team which must evaluate the pros and cons of the activity to make relevant recommendations. PMID:25359594

    Full Text Available The ash cloud of the Eyjafjallajökull1 volcano on Iceland caused closure of large parts of European airspace in April and May 2010. For the validation and improvement of the European volcanic ash forecast models several research flights were performed. Also the CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container flying laboratory, which routinely measures at cruise altitude (≈11 km performed three dedicated measurements flights through sections of the ash plume. Although the focus of these flights was on the detection and quantification of the volcanic ash, we report here on sulphur dioxide (SO2 and bromine monoxide (BrO measurements with the CARIBIC DOAS (Differential Optical Absorption Spectroscopy instrument during the second of these special flights on 16 May 2010. As the BrO and the SO2 observations coincide, we assume the BrO to have been formed inside the volcanic plume. Both SO2 and BrO observations agree well with simultaneous satellite (GOME-2 observations. SO2 column densities retrieved from satellite observations are often used as an indicator for volcanic ash. For SO2 some additional information on the local distribution can be derived from a~comparison of forward and back scan GOME-2 data. More details on the local plume size and position are retrieved by combining CARIBIC and GOME-2 data. 1Also referred to as: Eyjafjalla (e.g. Schumann et al., 2010, Eyjafjöll or Eyjafjoll (e.g. Ansmann et al., 2010.

    2015-03-01

    Full Text Available En tiempos de crisis capitalista e inestabilidad global, el nuevo regionalismo alternativo surge tanto como un puente y como un escudo entre los países en desarrollo y la incertidumbre global. Desde la Cumbre de las Américas de 2004, América del Sur ha ido desarrollando una nueva identidad regional, que no encaja en los conceptos actuales de regionalismo en América del norte, Europa o Asia. Este neo regionalismo que representa ALBA, la Unión de Naciones Suramericanas (UNASUR y la CELAC, refleja las heterogéneas configuraciones económicas, sociales y políticas de las fuerzas sociales y de orden político, que son únicas a nuestro continente. En tal sentido, se requiere una recta ordenación jurídica y la creación de un sistema integral de resolución de controversias que responda a nuestra realidad, sin la injerencia de agentes externos, pues tenemos las capacidades, las fortalezas y los juristas para construir una fuerte y poderosa neo institucionalidad de justicia que en caso de diferencias, permita entregar a este sistema de integración suramericano y sus integrantes una adecuada y eficaz seguridad jurídica, indispensable para seguir avanzando. Como parte integral del mismo se propone la creación de una Sala de Arbitraje y Mediación en materia de inversiones con carácter de permanencia e identidad suramericana y caribeña, para dar respuesta adjetiva y procesal a otras normas de relación internacional aceptadas por los países miembros, para así evitar demandas exageradas ante el CIADI, como el caso Exxon Mobil versus PDVSA.

    2014-03-01

    A laser spectrometer for automated monthly measurements of methane (CH4) mixing ratios aboard the CARIBIC passenger aircraft is presented. The instrument is based on a commercial Fast Greenhouse Gas Analyser (FGGA, Los Gatos Res.), which was adapted to meet the requirements imposed by unattended airborne operation. It was characterised in the laboratory with respect to instrument stability, precision, cross sensitivity to H2O, and accuracy. For airborne operation, a calibration strategy is described that utilises CH4 measurements obtained from flask samples taken during the same flights. The precision of airborne measurements is 2 ppb for 10 s averages. The accuracy at aircraft cruising altitude is 3.85 ppb. During aircraft ascent and descent, where no flask samples were obtained, instrumental drifts can be less accurately determined and the uncertainty is estimated to be 12.4 ppb. A linear humidity bias correction was applied to the CH4 measurements, which was most important in the lower troposphere. On average, the correction bias was around 6.5 ppb at an altitude of 2 km, and negligible at cruising flight level. Observations from 103 long-distance flights are presented that span a large part of the northern hemispheric upper troposphere and lowermost stratosphere (UT/LMS), with occasional crossing of the tropics on flights to southern Africa.

    Full Text Available Se caracterizaron 28 aislamientos de microorganismos solubilizadores de fosfatos (MSF encontrados en
    rizósferas de Avicennia germinans y Rhizophora mangle en dos manglares del Caribe colombiano, uno ubicado en la
    isla de San Andrés y otro en cercanías al municipio de Barú. De estos aislamientos se eligieron 17, con el fin
    medir su eficiencia fosfatosolubilizadora in vitro. Los aislamientos más eficientes fueron HSF9 (283,1 mg*L-1
    correspondiente al hongo filamentoso Aspergillus niger, y dos especies bacterianas aún no determinadas, denominadas BR4 y SA4(3 (190 y 226 mg*L-1*24h-1 respectivamente. Mediante caracteres fisiológicos se determinó que los aislamientos bacterianos B1 y B2, corresponden a los géneros Aeromicrobium y Aquaspirillum respectivamente, y que HSF2, SR2(1 y BL1 corresponden a la levadura Debaryomyces cf. hansenii. Se encontró una relación linear inversa entre el pH y el fosfato solubilizado in vitro (r2=0,7. Los valores medidos de actividad solubilizadora indican un excedente de fosfatos para al menos ocho aislamentos según datos de crecimiento (incremento de biomasa para hongos filamentosos y número de células*mL-1*24h-1 para bacterias y levaduras. Esto eventualmente puede ser aprovechado por plántulas de mangle, lo que sugiere que la presencia de MSF es un mecanismo presente en el ecosistema para suplir deficiencias edáficas de fosfatos.

Respecto a este análisis se pueden afirmar, por lo menos, dos rasgos relevantes: el primero es la importancia otorgada a las nuevas diásporas y su efecto en la actualidad; el segundo es la necesidad de ampliar el archivo literario mediante la integración de la música, la fotografía y el performance al proceso tradicional de hermenéutica. Así, al plantearse formas más incluyentes de interpretación, la crítica busca superar lugares comunes ya desgastados por el excesivo uso y sintonizarse con las inquietudes de creadoras y creadores jóvenes respecto a las realidades de la migración y su influjo en el actual redimensionamiento político del cuerpo. En esa medida, April Shemak, Donnete Francis y Rosamond King y otras escritoras problematizan la idea de un Caribe de puro contacto y difusión.

    Butler, David L.; von Guerard, Paul B.

    1996-01-01

    Salinity, or the dissolved-solids concentration, is the measure of salts such as sodium chloride, calcium bicarbonate, and calcium sulfate that are dissolved in water. About one-half of the salinity in the Colorado River Basin is from natural sources (U.S. Department of the Interior, 1995), such as thermal springs in the Glenwood-Dotsero area, located about 90 miles upstream from Grand Junction (fig. 1). Effects of human activities, such as irrigation, reservoir evaporation, and transbasin diversions, have increased the levels of salinity in the Colorado River. High salinity can affect industrial and municipal water users by causing increased water-treatment costs, increased deterioration of plumbing and appliances, increased soap needs, and undesirable taste of drinking water. High salinity also can cause lower crop yields by reducing water and nutrient uptake by plants and can increase agricultural production costs because of higher leaching and drainage requirements. Agricultural losses might occur when salinity reaches about 700?850 milligrams per liter (U.S Department of the Interior, 1994). Figure 1. Irrigated area in the Grand Valley and locations of sampling sites for the 1994?95 salinity study of the Colorado River. The Colorado River is the major source of irrigation water to the Grand Valley (fig. 1) and also is one source of water for the Clifton Water District, which supplies domestic water to part of the eastern Grand Valley. During spring and early summer in 1994, the Colorado River in the Grand Valley had lower than average streamflow. There was concern by water users about the effect of this low streamflow on salinity in the river. In 1994, the U.S. Geological Survey (USGS), in cooperation with the Colorado River Water Conservation District, began a study to evaluate salinity in the Colorado River. This fact sheet describes results of that study. The specific objectives of the fact sheet are to (1) compare salinity in the Colorado River among

  9. Gunnison, Colorado subpile study report. Revision 1

    International Nuclear Information System (INIS)

    To protect human health and the environment, the Uranium Mill Tailings Remedial Action (UMTRA) Project will remediate the uranium mill tailings site at Gunnison Colorado. There are explicit requirements (i.e., 40 CFR Part 192) for the surface remediation of radiologically contaminated soils on UMTRA sites. The removal of subpile sediment to the depth required by 40 CFR Part 192 will leave in place deeper foundation sediment that is contaminated with hazardous constituents other than radium-226 and thorium-230. The Department of Energy and the Colorado Department of Health have questioned whether this contaminated soil could potentially act as a continuing source of ground water contamination even after surface remediation based on 40 CFR Part 192 is complete. To evaluate the subpile sediments as a potential source of ground water contamination, the Gunnison Subpile study was initiated. This report summarizes the results and findings of this study

    Full Text Available La producción de frijol en Centroamérica es llevada a cabo mayormente en laderas de suelos marginales, limitada por diversos factores bióticos y abióticos. Más de 350,000 t de este grano se producen en cerca de 0,5 millones de hectáreas, con rendimientos promedios de 678 kg/ha. La mayoría de los productores de frijol utilizan bajos insumos y muy pocas fincas están mecanizadas. El autoconsumo es alto; sin embargo, una alta proporción de este grano es comprado por intermediarios. En Honduras, el frijol es el sétimo cultivo en valor económico y es el de mayor rentabilidad entre el maíz, arroz y sorgo. Las dos clases comerciales más importantes en Centroamérica son el frijol rojo y negro pequeños (raza Mesoamérica. El mejoramiento de estos tipos de frijol se ha enfocado en el desarrollo de resistencia a enfermedades (mosaico común, mosaico dorado, antracnosis, mancha angular, roya, mustia hilachosa y bacteriosis común e insectos (principalmente picudo de la vaina; y tolerancia a baja fertilidad, sequía y calor. Programas adecuados de hibridación, evaluación y selección son usados para el desarrollo de cultivares con resistencia múltiple, alto rendimiento, buena adaptación y aceptación comercial. La ampliación de la base genética se obtiene usando fuentes de germoplasma Andino y Mesoamericano en la etapa de hibridación. La selección simultánea por varios caracteres y pruebas multilocalidades son utilizadas. Los viveros y ensayos de adaptación y rendimiento de líneas avanzadas son distribuídos a países de Centroamérica, México, y El Caribe.

    Full Text Available Introducción: La tasa global de fecundidad en Colombia ha disminuido y el uso de los métodos anticonceptivos (MAC ha aumentado; sin embargo el inicio temprano de las relaciones sexuales cuando aún no se tienen los conocimientos necesarios que faciliten la sexualidad segura, induce al uso ineficaz con pérdida del potencial anticonceptivo. Materiales y Métodos: Estudio descriptivo de corte trasversal realizado con 64 adolescentes de un barrio de la ciudad de Santa Marta, Colombia, utilizando para ello un instrumento compuesto por tres dominios relacionados con conocimientos,  creencias y prácticas  sobre MAC.  Resultados: La edad media de los adolescentes fue de 16 años. El 65,6% conoce los MAC aunque únicamente 54,7% dice usarlos. El 71,9% piensan que las personas que usan los MAC son responsables e informadas. El 48,8% piensan que usar anticonceptivos tiene unos efectos secundarios como gordura y esterilidad. El método preferido es el preservativo y la decisión de utilizarlo la toma el hombre, y el inicio de las relaciones sexuales ocurre hoy a una edad muy temprana, hecho atribuido a la influencia cultural. Discusión: Los resultados de este estudio guardan relación con investigaciones realizados a nivel nacional e internacional, demuestran que el desconocimiento y las actitudes negativas sobre anticonceptivos son obstáculo para su uso. Conclusiones: Todos los participantes sustentaron conocimientos en anticonceptivos, existiendo vacíos en ese conocimiento y/o creencias sobre efectos secundarios que inciden negativamente en su uso: se les atribuye ocasionar aumento de peso esterilidad. El método más utilizado por los adolescentes es el preservativo. Cómo citar este artículo: Lapeira P, Acosta D, Vásquez M.

    The CARIBIC project (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) involves the monthly deployment of an instrument container equipped to make atmospheric measurements from aboard a commercial airliner, and has operated since 2005 from aboard a Lufthansa Airbus 340-600 . Measurements from the container include in-situ trace gas and aerosol analyses and the collection of aerosol and whole air samples for post-flight laboratory analysis. Measurements made from the sampling flasks include greenhouse gas (GHG), halocarbon and nonmethane hydrocarbon (NMHC) analysis. CARIBIC flights originate in Frankfurt, Germany with routes to India, East Asia, South America, North America and Africa, and typical aircraft cruising altitudes of 10-12km allow for the monitoring of the upper troposphere/lower stratosphere (UT/LS) along these routes. Data collected during the aircraft’s departure from and return to Frankfurt provide a 4 year time series of near-monthly measurements of the composition of the UT/LS above Europe. Here we present a discussion of the composition of short-lived trace gases in the whole air samples collected above Europe during CARIBIC flights. Over 150 air samples were collected between May 2005 and July 2009, or about 4 samples per month. Of the whole air samples collected, about 45% showed influence by stratospheric air (i.e. very low values of GHG, NMHC and halocarbons, elevated O3, high potential vorticity). The remaining samples were representative of the upper troposphere; back trajectories for these samples indicate that a little over half were collected in air masses that had been in the boundary layer within the previous 8 days. The predominant source regions for these samples were the Gulf of Mexico and continental North America. Owing to their wide range of chemical lifetimes and the varying composition of emissions, short-lived trace gases transported to the UT/LS can be useful indicators of source

    Technology and engineering have helped make mining safer and cleaner for both humans and the environment. Inevitably, mineral development entails costs as well as benefits. Developing a mine is an environmental, engineering, and planning challenge that must conform to many Federal, State, and local regulations. Community collaboration, creative design, and best management practices of sustainability and biodiversity can be positive indicators for the mining industry. A better understanding of aesthetics, culture, economics, geology, climate, vegetation and wildlife, topography, historical significance, and regional land planning is important in resolving land-use issues and managing mineral resources wisely. Ultimately, the consuming public makes choices about product use (including water, food, highways, housing, and thousands of other items) that influence operations of the mineral industry. Land planners, resource managers, earth scientists, designers, and public groups have a responsibility to consider sound scientific information, society's needs, and community appeals in making smart decisions concerning resource use and how complex landscapes should change. An effort to provide comprehensive geosciences data for land management agencies in central Colorado was undertaken in 2003 by scientists of the U.S. Geological Survey and the Colorado Geological Survey. This effort, the Central Colorado Assessment Project, addressed a variety of land-use issues: an understanding of the availability of industrial and metallic rocks and minerals, the geochemical and environmental effects of historic mining activity on surface water and groundwater, and the geologic controls on the availability and quality of groundwater. The USDA Forest Service and other land management agencies have the opportunity to contribute to the sustainable management of natural aggregate and other mineral resources through the identification and selective development of mineral resources and the

  12. Cancer incidence study in Mesa County, Colorado

    International Nuclear Information System (INIS)

    In November of 1982 the Colorado Department of Health completed an epidemiologic investigation of leukemia, multiple myeloma, and cancers of the lung, stomach, pancreas and colon in Mesa County, Colorado for the years 1970 to 1979. This investigation was performed in response to a concern that the presence of uranium mill tailings in some Mesa County homes presents a potential cancer hazard. The results of the investigation show that the incidence of multiple myeloma, colon, stomach and pancreatic cancer are not above expected rates. The incidence of leukemia is not above expected rates for the entire study period, 1970 to 1979. The incidence of lung cancer appears elevated when compared to the The Third National Cancer Survey data for Colorado but lower than expected when compared to Surveillance, Epidemiology and End Results data. To further examine the leukemia and lung cancer incidence findings, a case/control study was conducted. The controls consisted of colon, stomach and pancreatic cancer cases. The results of the leukemia case/control analysis show no association with the radiation exposure variables: occupational radiation exposure; uranium mining exposure; having ever lived in a type A home (uranium tailings home); and radiation therapy. The lung cancer case/control analysis shows a significant association with only the radiation exposure variable, uranium mining history, indicating cases were more likely to have been uranium miners than were controls. As with leukemia, the study found no association between lung cancer and living in a uranium mill tailings home. The relatively low radiation exposures typical of type A homes and the small number of persons exposed make it very difficult to establish, by epidemiologic methods, that a risk exists

    Glen Canyon Dam has greatly altered the Colorado River in Grand Canyon. The Little Colorado River (LCR) provides a small refuge of seasonally warm and turbid water that is thought to be more suitable than the Colorado River for endangered humpback chub Gila cypha. However, the LCR has low productivity and contains nonnative fishes and parasites, which pose a threat to humpback chub. The Colorado River hosts a different suite of nonnative fishes and is cold and clear but more productive. We compared condition factor (K), abdominal fat index (AFI), and presence and number of two introduced pathogenic parasites (Lernaea cyprinacea and Bothriocephalus acheilognathi) between juvenile (parasitism and poorer body condition in humpback chub from the LCR challenge the paradigm that warmer LCR waters are more suitable for humpback chub than the colder Colorado River and indicate the need to consider the importance and benefits of all available habitats, as well as biotic and abiotic factors, when managing endangered species and their environment.

    Colorado has undergone substantial changes in forests due to urbanization, wildfires, insect-caused tree mortality, and other human and environmental factors. The U.S. Geological Survey Rocky Mountain Geographic Science Center evaluated and developed a methodology for applying remotely-sensed imagery for assessing conifer health in Colorado. Two classes were identified for the purposes of this study: healthy and unhealthy (for example, an area the size of a 30- x 30-m pixel with 20 percent or greater visibly dead trees was defined as ?unhealthy?). Medium-resolution Landsat 5 Thematic Mapper imagery were collected. The normalized, reflectance-converted, cloud-filled Landsat scenes were merged to form a statewide image mosaic, and a Normalized Difference Vegetation Index (NDVI) and Renormalized Difference Infrared Index (RDII) were derived. A supervised maximum likelihood classification was done using the Landsat multispectral bands, the NDVI, the RDII, and 30-m U.S. Geological Survey National Elevation Dataset (NED). The classification was constrained to pixels identified in the updated landcover dataset as coniferous or mixed coniferous/deciduous vegetation. The statewide results were merged with a separate health assessment of Grand County, Colo., produced in late 2008. Sampling and validation was done by collecting field data and high-resolution imagery. The 86 percent overall classification accuracy attained in this study suggests that the data and methods used successfully characterized conifer conditions within Colorado. Although forest conditions for Lodgepole Pine (Pinus contorta) are easily characterized, classification uncertainty exists between healthy/unhealthy Ponderosa Pine (Pinus ponderosa), Pi?on (Pinus edulis), and Juniper (Juniperus sp.) vegetation. Some underestimation of conifer mortality in Summit County is likely, where recent (2008) cloud-free imagery was unavailable. These classification uncertainties are primarily due to the spatial and

    The Upper Colorado River Basin in Colorado and Utah is 1 of 60 study units selected for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment program, which began full implementation in 1991. Understanding the environmental setting of the Upper Colorado River Basin study unit is important in evaluating water-quality issues in the basin. Natural and human factors that affect water quality in the basin are presented, including an overview of the physiography, climatic conditions, general geology and soils, ecoregions, population, land use, water management and use, hydrologic characteristics, and to the extent possible aquatic biology. These factors have substantial implications on water-quality conditions in the basin. For example, high concentrations of dissolved solids and selenium are present in the natural background water conditions of surface and ground water in parts ofthe basin. In addition, mining, urban, and agricultural land and water uses result in the presence of certain constituents in the surface and ground water of the basin that can detrimentally affect water quality. The environmental setting of the study unit provides a framework of the basin characteristics, which is important in the design of integrated studies of surface water, ground water, and biology.

    The US Department of Energy is developing an estimate of the hydropower development potential in this country. Hydropower Evaluation Software (HES) is a computer model that was developed by the Idaho National Engineering Laboratory for this purpose. HES measures the potential hydropower resources available in the United States, using uniform criteria for measurement. The software was developed and tested using hydropower information and data provided by the Southwestern Power Administration. It is a dBASE, menu-driven software application. HES allows the personal computer user to assign environmental attributes to potential hydropower sites, calculate development suitability factors for each site based on the environmental attributes present, and generate reports based on these suitability factors. This report details the resource assessment results for the State of Colorado.

    As part of its effort to more accurately describe the nations geothrmal resource potential, the US Department of Energy/Division of Geothermal Energy contracted with the Colorado Geological survey to appraise the hydrothermal (hot water) geothermal resources of Colorado. Part of this effort required that the amount of energy that could possibly be contained in the various hydrothermal systems in Colorado be estimated. The findings of that assessment are presented. To make these estimates the geothermometer reservoir temperatures estimated by Barrett and Pearl (1978) were used. In addition, the possible reservoir size and extent were estimated and used. This assessment shows that the total energy content of the thermal systems in Colorado could range from 4.872 x 10{sup 15} BTU's to 13.2386 x 10{sup 15} BTU's.

MATERIAL Y MÉTODOS: Se construyó una base de datos sobre componentes de los sistemas de salud tradicionales en nueve países de América Latina y el Caribe, mediante la creación de una red de individuos e instituciones de distintos países que estuvieran interesados en participar como informantes especializados con diferentes perfiles. La información para este estudio de tipo cualitativo se levantó, sistematizó y analizó entre marzo y diciembre de 1998. RESULTADOS: Se exponen los resultados obtenidos del tema de regulación de la medicina tradicional dividiendo a los países en tres grupos: a los que cuentan con algún tipo de desarrollo en materia de legislación; b los que están trabajando en el proceso de legislación, y c los que no tienen legislación y el proceso de regulación es incipiente. CONCLUSIONES: Se muestra que el proceso legislativo de la medicina tradicional es variado en la región y se encuentra en diferentes etapas. Esta variedad de estadios nos muestra la complejidad de regular una práctica terapéutica de prestadores con bajos niveles de entrenamiento formal, con prácticas variadas y que sustentan su ejercicio en usos y costumbres que en las mayoría de las ocasiones son difíciles de ubicar dentro de los estándares de los sistemas de salud oficiales. El estudio se considera importante para el diseño e implementación de políticas que permitan adecuar la oferta de servicios de medicina tradicional con las necesidades de las poblaciones que más hacen uso de ella.

Se identificó un total de representantes de 27 especies asociadas a los céspedes algales, agrupadas en 13 familias y 19 géneros. Para el Caribe colombiano se registró por primera vez Hippolyte pleuracanthus. Con base en el análisis de clasificación (UPGMA, se determinó que la estructura de las poblaciones de decápodos está relacionada con las características del sustrato rocoso y la composición algal, indicando que las diferencias en las poblaciones son consecuencia de una escala espacial, además del efecto antropogénico. Los resultados indicaron que las especies de crustáceos decápodos asociados a céspedes macroalgales, no se distribuyen de forma similar en la ecorregión de estudio, siendo Epialtus bituberculatus (65,7% la especie con mayor porcentaje de abundancia, seguida de Pachygrapsus transversus (6,2%, Eurypanopeus abbreviatus (3,8%, Acanthonyx petiverii (3,6% y Panopeus sp1.

    2008-01-01

    Full Text Available La ponencia examina el arte de la improvisación vocal (o soneo de Ismael Rivera (Maelo, reconocido como “ el Sonero Mayor ” de la música “tropical”. Analiza cómo mucha de la riqueza del soneo de Maelo, más que en la retahíla de palabras que improvisa, se encuentra en el swing de su manera de hilvanar esas improvisaciones, desarrollando modulaciones rítmicas a l a manera del bailador en diálogo con el tambor repicador en la memoria caribeña de sus primeras músicas emergiendo de su herencia cultural africana. Estas primeras músicas partían de una realidad, en medida considerable, “despalabrada”, terrible carimbo de la esclavitud. El análisis del soneo de Maelo es muy importante para comprender la salsa, un movimiento musical liderado por la diáspora caribeña en Nueva York que alcanzó una enorme difusión internacional. Su trayectoria como cantante se ubica en los añ os de transición entre la música afrocaribeña tradicional y las nuevas sonoridades que asume esa música en la expresión salsera. Fue, de hecho, en Nueva York a donde emigró en 1967 y como parte del boom salsero que se iniciaba entonces, que su soneo alca nzó su máximo desarrollo artístico, pero incorporando siempre la memoria ancestral y el hondo sentido comunal de sus inicios sobre todo con el Combo de Cortijo en los barrios populares del Puerto Rico de los años cincuenta. La manera como Maelo “apalabró” su swing le imprimió una gran riqueza libertaria al soneo salsero convirtiéndolo en uno de los nuevos elementos centrales de dicha sonoridad diaspórica.

    Full Text Available Este trabajo describe el papel de las mujeres en los procesos de construcción de territorios y de regionalización en la costa Caribe colombiana. En primer lugar, se presenta la participación de las mujeres en los procesos adaptativos de los primeros habitantes, a través de su contribución a la creación de las culturas más importantes que surgieron en la región, tales como la Tairona y la Sinú. También, se consideran las acciones de resistencia de las mujeres indígenas que se opusieron a la invasión española, la participación de las mujeres en las luchas libertarias de africanos, indígenas, mestizos, zambos y criollos contra el colonialismo, y en la consolidación de la República, junto a su contribución en la construcción de los tejidos sociales que consolidaron la vida social de los pueblos y ciudades nacientes, lo que convirtió a las mujeres en integradoras de los grupos familiares, en la fuerza socializadora de las nuevas generaciones y en las garantes del funcionamiento de la estructura familiar. La segunda argumentación que se trabaja en el artículo es la referida a la participación de las mujeres en el proceso de regionalización del Caribe colombiano, en la que se establece y concluye que a pesar de que ésta se ha dado, no se ha garantizado el reconocimiento de sus intereses prácticos y estratégicos que permitan cambios en su posición social, económica y política, porque si bien hubo expresión de esos intereses en algunos de los foros realizados para concertar la visión y demandas de la región, el movimiento social no ha tenido acceso a la toma de decisiones, lo que no ha impedido si embargo, que en las últimas décadas éste se haya fortalecido.

    New 1:24,000-scale geologic mapping in the Colorado National Monument Quadrangle and adjacent areas, in support of the USGS Western Colorado I-70 Corridor Cooperative Geologic Mapping Project, provides new interpretations of and data for the stratigraphy, structure, geologic hazards in the area from the Colorado River in Grand Valley onto the Uncompahgre Plateau. The plateau drops abruptly along northwest-trending structures toward the northeast 800 m to the Redlands area and the Colorado River in Grand Valley. In addition to common alluvial and colluvial deposits, surficial deposits include Holocene and late Pleistocene charcoal-bearing valley-fill deposits, late to middle Pleistocene river-gravel terrace deposits, Holocene to middle Pleistocene younger, intermediate, and old fan-alluvium deposits, late to middle Pleistocene local gravel deposits, Holocene to late Pleistocene rock-fall deposits, Holocene to middle Pleistocene young and old landslide deposits, Holocene to late Pleistocene sheetwash deposits and eolian deposits, and Holocene Cienga-type deposits. Only the lowest part of the Upper Cretaceous Mancos Shale is exposed in the map area near the Colorado River. The Upper and Lower? Cretaceous Dakota Formation and the Lower Cretaceous Burro Canyon Formation form resistant dipslopes in the Grand Valley and a prominent ridge on the plateau. Less resistant strata of the Upper Jurassic Morrison Formation consisting of the Brushy Basin, Salt Wash, and Tidwell Members form slopes on the plateau and low areas below the mountain front of the plateau. The Middle Jurassic Wanakah Formation nomenclature replaces the previously used Summerville Formation. Because an upper part of the Middle Jurassic Entrada Formation is not obviously correlated with strata found elsewhere, it is therefore not formally named; however, the lower rounded cliff former Slickrock Member is clearly present. The Lower Jurassic silica-cemented Kayenta Formation forms the cap rock for the Lower

    2013-12-30

    The Colorado Better Buildings project intended to bring new and existing energy efficiency model programs to market with regional collaboration and funding partnerships. The goals for Boulder County and its program partners were to advance energy efficiency investments, stimulate economic growth in Colorado and advance the state’s energy independence. Collectively, three counties set out to complete 9,025 energy efficiency upgrades in 2.5 years and they succeeded in doing so. Energy efficiency upgrades have been completed in more than 11,000 homes and businesses in these communities. Boulder County and its partners received a $25 million BetterBuildings grant from the U.S. Department of Energy under the American Recovery and Reinvestment Act in the summer of 2010. This was also known as the Energy Efficiency and Conservation Block Grants program. With this funding, Boulder County, the City and County of Denver, and Garfield County set out to design programs for the residential and commercial sectors to overcome key barriers in the energy upgrade process. Since January 2011, these communities have paired homeowners and business owners with an Energy Advisor – an expert to help move from assessment to upgrade with minimal hassle. Pairing this step-by-step assistance with financing incentives has effectively addressed many key barriers, resulting in energy efficiency improvements and happy customers. An expert energy advisor guides the building owner through every step of the process, coordinating the energy assessment, interpreting results for a customized action plan, providing a list of contractors, and finding and applying for all available rebates and low-interest loans. In addition to the expert advising and financial incentives, the programs also included elements of social marketing, technical assistance, workforce development and contractor trainings, project monitoring and verification, and a cloud-based customer data system to coordinate among field

    Full Text Available The Colorado River bridge is located in a 95 m deep canyon, with a 122 m span. To choose the type of bridge, it has been endeavoured to use the largest possible number of national building materials which, together with the difficulty of reaching the site, meant that a series of classical solutions had to be rejected. That of an arch bridge was adopted, with a reversed support on prestressed cables, on which the road passes. The system is based on the hanging bridge principle, but with the rolling track resting on the cables, instead of hanging from them. There is a first cover, made up of prefabricated components, on the cables, which strengthens the bridge's stability. This cover supports three portal-columns, the pillars of the final roadway. The cables were prestressed from the heads of the two sloping pillars. The two side spans were designed with prefabricated T girders.El puente Río Colorado está situado en un cañón de 95 m de profundidad, salvando una luz de 122 m. Para la elección del tipo de puente se ha procurado emplear el mayor número posible de materiales de construcción nacionales, lo que, unido a la dificultad de acceso a la obra, hizo que se rechazaran una serie de soluciones clásicas. Se adoptó la de un puente-arco con un soporte invertido sobre cables pretensados, encima del cual descansa la calzada. El sistema está basado en los principios del puente colgante, pero apoyando el camino de rodadura en los cables, en lugar de colgarlo de ellos. Sobre los cables existe una primera cubierta, integrada por elementos prefabricados, que refuerza la estabilidad del puente. Esta cubierta soporta tres pórticos-columna, pilares de la calzada definitiva. El pretensado de los cables se realizó desde las cabezas de dos pilares inclinados.

  7. Approaches to local climate action in Colorado

    2011-12-01

    Though climate change is a global problem, the impacts are felt on the local scale; it follows that the solutions must come at the local level. Fortunately, many cities and municipalities are implementing climate mitigation (or climate action) policies and programs. However, they face many procedural and institutional barriers to their efforts, such of lack of expertise or data, limited human and financial resources, and lack of community engagement (Krause 2011). To address the first obstacle, thirteen in-depth case studies were done of successful model practices ("best practices") of climate action programs carried out by various cities, counties, and organizations in Colorado, and one outside Colorado, and developed into "how-to guides" for other municipalities to use. Research was conducted by reading documents (e.g. annual reports, community guides, city websites), email correspondence with program managers and city officials, and via phone interviews. The information gathered was then compiled into a series of reports containing a narrative description of the initiative; an overview of the plan elements (target audience and goals); implementation strategies and any indicators of success to date (e.g. GHG emissions reductions, cost savings); and the adoption or approval process, as well as community engagement efforts and marketing or messaging strategies. The types of programs covered were energy action plans, energy efficiency programs, renewable energy programs, and transportation and land use programs. Between the thirteen case studies, there was a range of approaches to implementing local climate action programs, examined along two dimensions: focus on climate change (whether it was direct/explicit or indirect/implicit) and extent of government authority. This benchmarking exercise affirmed the conventional wisdom propounded by Pitt (2010), that peer pressure (that is, the presence of neighboring jurisdictions with climate initiatives), the level of

Su reconocimiento como área socio-cultural, como espacio de transculturación y de sincretismo, depende de una teleología conciliadora de la diferencia. Cuestionando esta narrativa hegemónica, el presente ensayo ofrece una relectura de Fernando Ortiz, Edouard Glissant y Manuel Zapata Olivella a partir de lo que denomino el desafío a la pretensión unitaria de la identidad por vía negativa. Reflexiono sobre el potencial crítico del antagonismo y la violencia en la construcción de imaginarios históricos alternativos desde y sobre la región. As a site of intense relationality and encounter, the Caribbean has been constituted as a singular phenomenon. Its affirmation as a socio-cultural area, as the space of transculturación and syncretism, is determined by a conciliatory teleology regarding difference. To question this hegemonic cultural discourse, this essay offers a re-reading of Fernando Ortiz, Edouard Glissant and Manuel Zapata Olivella from what I will term a negative approach to and challenge of the unitary claim of identity. Through their work, I reflect on the critical potential of antagonism and violence in the construction of an alternative historical imaginary from and about the region.

    Full Text Available Los autores de este artículo ofrecen una explicación del origen del turismo de cruceros en Cozumel a partir de la reconstrucción de la historia económica moderna de esa isla mexicana. Se necesitó más de centuria y media para que el pueblo fundado en aquella ínsula, San Miguel de Cozumel (1848, se transformara en una ciudad cosmopolita, en el destino más importante de turismo de cruceros en el país. Cozumel comenzó como una anodina propiedad nacional, casi abandonada. Sus colonos del siglo XIX vieron pasar de lado el progreso, o mejor dicho de largo, porque los buques mercantes y de pasajeros nunca se detuvieron en la isla, a menos que los obligara un huracán, una avería mecánica o la necesidad de agua dulce. Durante la época virreinal y hasta inicios del siglo XX Cozumel sólo interesaba a la cartografía marítima, sus 45 kilómetros de extensión fueron una buena referencia para las embarcaciones que transitaban por esa ruta del mar Caribe. Pero esa misma condición la convirtió en un exitoso puerto de cruceros.

    Cater, Fred W.

    1953-01-01

    The Gypsum Gap quadrangle is one eighteen 7 1/2-minute quadrangles covering the principal carnotite-producing area of southwestern Colorado. The geology of these quadrangles was mapped by the U.S. Geological Survey for the Atomic Energy Commission as part of a comparative study of carnotite deposits. The rocks exposed in the eighteen quadrangles consist of crystalline rocks of pre-Cambrian age and sedimentary rocks that range in age from late Paleozoic to Quaternary. Over much of the area the sedimentary rocks are flat lying, but in places the rocks are disrupted by high-angle faults, and northwest-trending folds. Conspicuous among the folds are large anticlines having cores of intrusive salt and gypsum. Most of the carnotite deposits are confined to the Salt Wash sandstone member of the Jurassic Morrison formation. Within this sandstone, most of the deposits are spottily distributed through a arcuate zone known as the "Uravan Mineral Belt". Individual deposits range in size from irregular masses containing only a few tons of ore to large, tabular masses containing many thousands of tons. The core consists largely of sandstone selectively impregnated and in part replaced by uranium and vanadium minerals.

    The Davis Mesa quadrangle is one of eighteen 7 1/2-minute quadrangles covering the principal carnotite-producing area of southwestern Colorado. The geology of these quadrangles was mapped by the U.S. Geological Survey for the Atomic Energy Commission as part of a comprehensive study of carnotite deposits. The rocks exposed in the eighteen quadrangles consist of crystalline rocks of pre-Cambrian age and sedimentary rocks that range in age from late Paleozoic to Quaternary. Over much of the area the sedimentary rocks are flat lying, but in places the rocks are disrupted by hih-angle faults, and northwest-trending folds. Conspicuous among the folds are large anticlines having cores of intrusive salt and gypsum. Most of the carnotite deposits are confined to the Salt Wash sandstone member of Jurassic Morrison formation. Within this sandstone, most of the deposits are spottily distributed through an arcuate zone known as "Uruvan Mineral Belt". Individual deposits range in size from irregular masses containing only a few tons of ore to large, tabular masses containing many thousands of tons. The ore consists largely of sandstone selectively impregnated and in part replaced by uranium and vanadium minerals. Most of the deposits appear to be related to certain sedimentary structures in sandstones of favorable composition.

  7. Dendroclimatic reconstructions for the southern Colorado plateau

    1995-09-01

    A geographical network of climate sensitive tree-ring chronologies consisting of 25 archaeological sequences and two bristlecone pine series provides the basis for high resolution reconstructions of low and high frequency climatic variability on the southern Colorado Plateau over the last 1,500 years. Qualitative and quantitative dendroclimatic analyses of these data produce annual retrodictions of yearly and seasonal precipitation and summer Palmer Drought Severity Indices for each station and reconstructions of regional scale patterns in climatic variability. These reconstructions provide detailed information on climatic fluctuations that affected biotic and human populations as well as long-term baseline data for evaluating present-day climate and estimating future climatic trends. When integrated with other measures of past environmental variability, these reconstructions specify periods of favorable and unfavorable environmental conditions that would have affected past human populations of the region. The severest degradation, which occurred between A.D. 1250 and 1450, probably was causally related to numerous cultural changes that occurred at the end of the l3th century including the Anasazi abandonment of the Four Comers area. Projecting environmental patterns that characterized the last two millennia into the future indicates potential hazards to long term uranium mill waste disposal and containment and the potential and limitations of environmental restoration.

    This report is a summary of environmental information gathered during a review of the documents pertaining to Project Rulison and interviews with personnel who worked on the project. Project Rulison was part of Operation Plowshare (a program designed to explore peaceful uses for nuclear devices). The project consisted of detonating a 43-kiloton nuclear device on September 10, 1969, in western Colorado to stimulate natural gas production. Following the detonation, a reentry well was drilled and several gas production tests were conducted. The reentry well was shut-in after the last gas production test and was held in standby condition until the general cleanup was undertaken in 1972. A final cleanup was conducted after the emplacement and testing wells were plugged in 1976. However, some surface radiologic contamination resulted from decontamination of the drilling equipment and fallout from the gas flaring during drilling operations. With the exception of the drilling effluent pond, all surface contamination at the Rulison Site was removed during the cleanup operations. All mudpits and other excavations were backfilled, and both upper and lower drilling pads were leveled and dressed. This report provides information regarding known or suspected areas of contamination, previous cleanup activities, analytical results, a review of the regulatory status, the site`s physical environment, and future recommendations for Project Ruhson. Based on this research, several potential areas of contamination have been identified. These include the drilling effluent pond and mudpits used during drilling operations. In addition, contamination could migrate in the gas horizon.

  11. Salinization of the Upper Colorado River - Fingerprinting Geologic Salt Sources

    Science.gov (United States)

    Tuttle, Michele L.W.; Grauch, Richard I.

    2009-01-01

    Salt in the upper Colorado River is of concern for a number of political and socioeconomic reasons. Salinity limits in the 1974 U.S. agreement with Mexico require the United States to deliver Colorado River water of a particular quality to the border. Irrigation of crops, protection of wildlife habitat, and treatment for municipal water along the course of the river also place restrictions on the river's salt content. Most of the salt in the upper Colorado River at Cisco, Utah, comes from interactions of water with rock formations, their derived soil, and alluvium. Half of the salt comes from the Mancos Shale and the Eagle Valley Evaporite. Anthropogenic activities in the river basin (for example, mining, farming, petroleum exploration, and urban development) can greatly accelerate the release of constituents from these geologic materials, thus increasing the salt load of nearby streams and rivers. Evaporative concentration further concentrates these salts in several watersheds where agricultural land is extensively irrigated. Sulfur and oxygen isotopes of sulfate show the greatest promise for fingerprinting the geologic sources of salts to the upper Colorado River and its major tributaries and estimating the relative contribution from each geologic formation. Knowing the salt source, its contribution, and whether the salt is released during natural weathering or during anthropogenic activities, such as irrigation and urban development, will facilitate efforts to lower the salt content of the upper Colorado River.

  7. Is the Profile of the Colorado River in the Colorado Plateau in Equilibrium With Bedrock?

    Science.gov (United States)

    Mackley, R. D.; Pederson, J. L.

    2003-12-01

    The Colorado River sets the pace for the erosion of the Colorado Plateau and part of the Rocky Mountains, and the evolution of its long-profile may hold the key to resolving debate over the region's late Cenozoic erosional and tectonic history. Significant reach (10 km) and canyon-scale (100 km) gradient variations occur along the modern profile of this mixed bedrock-alluvial river, and there are multiple hypotheses for the controls on its gradient: 1) knickzones related to active tectonics in western Grand Canyon, 2) coarse bed material from tributary side-canyons, and 3) bedrock resistance as a direct control with respect to channel substrate or an indirect control in terms of hillslope processes in tributary catchments and the production and comminution of bed material. The goal of this study is to test for a spatial relation between hydraulic driving forces and bedrock resisting forces at reach and canyon-scales within and between Glen and Grand canyons. The river encounters diverse rock types that vary in hardness and fracture density. Field and GIS results aimed at testing the bedrock resistance hypothesis for Glen and Grand canyons indicate a spatial relation between rock-mass strength (RMS) and channel gradient. Reach-scale gradients vary as much as a factor of 20 through Grand Canyon, with steep reaches having significantly higher compressive strengths and wide fracture spacings. Glen Canyon, on the other hand, has dramatically lower channel gradient, weaker RMS properties, and reaches with steep gradients that do not correlate to either debris fans or changes in bedrock type but do coincide with geologic structures. The presence of a bedrock or debris-fan frequency correlation to the majority of gradient variations argues against tectonic origins of knickzones and suggests a relation between bedrock resistance and the profile of the Colorado River exists. However, when these results are combined with the distribution of tributary debris fans and their

    2005-01-01

    The publication of The Colorado Plateau: Cultural, Biological, and Physical Research in 2004 marked a timely summation of current research in the Four Corners states. This new volume, derived from the seventh Biennial Conference on the Colorado Plateau in 2003, complements the previous book by focusing on the integration of science into resource management issues. The 32 chapters range in content from measuring human impacts on cultural resources, through grazing and the wildland-urban interface issues, to parameters of climate change on the Plateau. The book also introduces economic perspectives by considering shifting patterns and regional disparities in the Colorado Plateau economy. A series of chapters on mountain lions explores the human-wildland interface. These chapters deal with the entire spectrum of challenges associated with managing this large mammal species in Arizona and on the Colorado Plateau, conveying a wealth of timely information of interest to wildlife managers and enthusiasts. Another provocative set of chapters on biophysical resources explores the management of forest restoration, from the micro scale all the way up to large-scale GIS analyses of ponderosa pine ecosystems on the Colorado Plateau. Given recent concerns for forest health in the wake of fires, severe drought, and bark-beetle infestation, these chapters will prove enlightening for forest service, park service, and land management professionals at both the federal and state level, as well as general readers interested in how forest management practices will ultimately affect their recreation activities. With broad coverage that touches on topics as diverse as movement patterns of rattlesnakes, calculating watersheds, and rescuing looted rockshelters, this volume stands as a compendium of cutting-edge research on the Colorado Plateau that offers a wealth of insights for many scholars.

Four cluster analysis methods were applied to a test data set and their capability of separating the data points into scientifically reasonable clusters was assessed. The best method was applied to seasonal data subsets for summer and winter resulting in five cluster or air mass types: stratosphere, tropopause, free troposphere, high clouds, and boundary layer influenced. Other source clusters, like aircraft emissions could not be resolved in the present data set with the used methods. While the cluster separation works satisfactory well for the summer data, in winter interpretation is more difficult, which is attributed to either different vertical transport pathways or different chemical lifetimes in the two seasons. The geographical distribution of the clusters together with histograms for nucleation and Aitken mode particles within each cluster are presented. Aitken mode particle number concentrations show a clear vertical gradient with the lowest values in the lowermost stratosphere (750–2820 particles/cm3 STP, minimum of the two 25%- and maximum of the two 75%-percentiles of both seasons and the highest values for the boundary-layer-influenced air (4290–22 760 particles/cm3 STP. Nucleation mode particles are also highest in the boundary-layer-influenced air (1260–29 500 particles/cm3 STP, but are lowest in the free troposphere (0–450 particles/cm3 STP. The given submicrometer particle number concentrations represent the

    Full Text Available Este texto explora los modos en que las violencias relacionadas con la orientación sexual o la identidad de género interactúan y se construyen mutuamente con las violencias de los conflictos armados. Se argumenta que tales violencias hacen parte de la redefinición del contrato social en procesos de transición política que va a la par de una redefinición del contrato sexual de la nación. Para ello se explora la historia de vida de una joven costeña y como desde diferentes aspectos de su vida ha experimentado las interacciones entre las violencias sociopolíticas que vive el país y la región y las violencias relacionadas con el género y la orientación sexual. La historia problematiza clasificaciones categóricas de las violencias y demandan derechos por separado y las categorías fijas de sujetos definidas desde una condición de vulnerabilidad. Permite además ilustrar como en las transiciones entre los conflictos unas formas de violencia se transmutan y recomponen manteniendo para algunos sectores sociales el ser objeto permanente de violencia. Lo anterior en las contradicciones generadas en un contexto de apertura económica y de promoción de la región Caribe como polo de turismo nacional e internacional que permite ciertos cambios pero impide otros.

    Full Text Available Soon after the Cuban Revolution it was found out that its own survival depended mostly on the dissemination of its message in the Caribbean area, and specially on the need to export its revolutionary experience to those territories which, as it was the case with the Dominican Republic, wished to get free from the last dictators in America, the most famous among the latter being Rafael Leónidas Trujillo Molina. Spain's external position was peculiar in this regard. Within the general framework of its Latin American policy, aiming at the maintenance of diplomatic links in the area, Madrid endeavoured to keep good relationships both with Trujillo 's Dominican Republic and with revolutionary Cuba.

    La Revolución Cubana no tardó en descubrir que una de las claves fundamentales para su propia supervivencia, que estaba ligada, asimismo, a su ideario de insurrección continental era la expansión de su mensaje en la propia zona del Caribe y, en concreto, la necesidad de exportar sus prácticas insurgentes hacia aquellos territorios que, como la República Dominicana, estaban deseando liberarse del yugo de los últimos dictadores de América, entre los que alcanzaba la cúspide de la impopularidad Rafael Leónidas Trujillo Molina. La posición exterior de España, en tales circunstancias, no dejaba de ser peculiar. En el contexto general de su política hacia América Latina que ansiaba mantener los vínculos diplomáticos, al margen de contingencias más o menos coyunturales, Madrid hizo todo lo posible por entenderse tanto con la República Dominicana del dictador Trujillo como con la Cuba revolucionaria del rebelde Castro.

En las islas de Providencia y Santa Catalina, el paso del huracán Beta en octubre de 2005 dejó impactos severos, principalmente en este sector, lo que demandó investigaciones para contribuir a la gestión del riesgo. El objetivo de la presente investigación fue estimar la vulnerabilidad socio­económica de los agricultores de las islas de Providencia y Santa Catalina, frente a huracanes. La metodología se basó en establecer indicadores que se ajustaron a partir de protocolos y trabajos internacionales, mediante la realización de una encuesta mixta (cualitativa y cuantitativa, con 66 preguntas, aplicada al 56% del total de agricultores durante el año 2008. Los principales resultados obtenidos demostraron que, en términos generales, nueve de las diez microcuencas de las islas tienen un nivel medio de vulnerabilidad y muy alto en la de San Felipe. Los indicadores socio­económicos con un alto y muy alto grado de vulnerabilidad, fueron la falta de organización comunitaria, la falta de estímulos financieros y los bajos ingresos económicos. Con estos resultados, se logró proponer lineamientos para acciones correctivas y de prevención frente al riesgo social construido.

    Full Text Available Large volcanic eruptions impact significantly on climate and lead to ozone depletion due to injection of particles and gases into the stratosphere where their residence times are long. In this the composition of volcanic aerosol is an important but inadequately studied factor. Samples of volcanically influenced aerosol have been collected following the Kasatochi (Alaska, Sarychev (Russia and also during the Eyjafjallajökull (Iceland eruptions in the period 2008–2010. Sampling was conducted by the CARIBIC platform during regular flights at an altitude of 10–12 km as well as during dedicated flights through the volcanic clouds from the eruption of Eyjafjallajökull in spring 2010. Elemental concentrations of the collected aerosol were obtained by accelerator-based analysis. Aerosol from the Eyjafjallajökull volcanic clouds was identified by high concentrations of sulfur and elements pointing to crustal origin, and confirmed by trajectory analysis. Signatures of volcanic influence were also used to detect volcanic aerosol in stratospheric samples collected following the Sarychev and Kasatochi eruptions. In total it was possible to identify 17 relevant samples collected between 1 and more than 100 days following the eruptions studied. The volcanic aerosol mainly consisted of ash, sulfate and included a carbonaceous component. Samples collected in the volcanic cloud from Eyjafjallajökull were dominated by the ash and sulfate component (~45% each while samples collected in the tropopause region and LMS mainly consisted of sulfate (50–77% and carbon (21–43%. These fractions were increasing/decreasing with the age of the aerosol. Because of the long observation period, it was possible to analyze the evolution of the relationship between the ash and sulfate components of the volcanic aerosol. From this analysis the residence time (1/e of sulfur dioxide in the studied volcanic cloud was estimated to be 45 days.

    Full Text Available El buceo es un uso alternativo y no consuntivo de la biodiversidad marina que, debidamente practicado, tiene bajo impacto ambiental, estimula la conservación de los arrecifes y es una opción económica para habitantes de áreas arrecifales o con potencial para el buceo. El archipiélago de San Andrés, Providencia y Santa Catalina, declarado por UNESCO Reserva Mundial de la Biosfera Seafl ower, con 65.000 km2 de Áreas Marinas Protegidas y un extenso complejo arrecifal coralino, tiene condiciones para convertirse en un sitio de buceo de nivel mundial. Sin embargo, es poco conocido. Esta investigación analiza el potencial económico del buceo en esta región y lo compara con el de sitios muy reconocidos como Bonaire y Gran Caimán. Mediante análisis de la disponibilidad a pagar de buzos visitantes, se intenta valorar el buceo y se caracteriza el tipo de buzos que vienen al archipiélago. Se encontró disposición a pagar cifras superiores a las que se paga actualmente en otras partes del Caribe. Con un potencial estimado en $241 millones de dólares de ingresos anuales, el buceo es una interesante alternativa de desarrollo económico sostenible para estas islas que, a pesar de recibir 360.000 turistas al año, aún presentan un 66.9% de pobreza y altos niveles de desempleo.

    Full Text Available Desde hace por lo menos una década, se ha insistido mucho en la orientación mundial del turismo como una opción de desarrollo. Visto a través de estudios de mercadotecnia, este sector económico, sea cual sea su versión, ha proliferado y sentado sus reales en los rincones más remotos del planeta. Del lado de las ciencias sociales existen investigaciones antropológicas abo - cadas a diversos temas; uno de ellos refiere una extensión del paradigma de la otredad al estudiar los procesos de reconocimiento del otro en contextos turísticos. Una línea de trabajo más a tono en México, guiada por la noción de patrimonio, coloca al centro la explotación de los recursos culturales y naturales como fuente de atractivos para visitantes. A partir de estas dos perspectivas se presenta el caso del turismo gay en Cancún, ubicado en la demandante región del Caribe mexi - cano, cuyo despegue e intentos de consolidación como segmento turístico enfrentan diversos di - lemas de orden social y político. En ese entorno se analizan las prácticas de consumo en donde las identidades colectivas se debaten frente a modelos hegemónicos expuestos en los espacios socia - les de interacción creados por el mercado y apropiados como escenarios de contienda simbólica.

    Full Text Available En las últimas décadas el Caribe colombiano ha experimentado un crecimiento económico importante y una intensificación de las interacciones con otras regiones del país y con el Estado central. En este contexto, el turismo aparece como una actividad que acentúa y acelera los cambios e intercambios sociales y económicos creando conflictos alrededor del control de los recursos. Sin embargo diversos individuos y colectivos crean al menos tantos espacios de acción como conflictos se perfilan. A partir del trabajo etnográfico realizado en una isla del Caribe colombiano, el presente artículo quiere mostrar cómo las tácticas de acceso y las estrategias locales de gestión del agua constituyen una entrada privilegiada para analizar las complejas redes sociales y los cambios económicos y políticos por los que atraviesa actualmente la región. Inspirada en los trabajos de Michel de Certeau (1990 quisiera afirmar que las poblaciones locales no sufren pasivamente las transformaciones que tienen lugar a gran escala y que parece sobrepasarlas sino que, en sus prácticas cotidianas, producen nuevas posibilidades de acción y alternativas creativas para asegurar su propio acceso a los recursos.

    Surface ozone (O3) can pose several health risks to humans, such as an increased number of and intensity of asthma attacks. Considering this, it is important that ozone levels are monitored. While municipal air quality monitors are present in cities like Boulder, Colorado, these monitors often only consider regional analysis, neglecting the variability of compounds, such as ozone or carbon monoxide, over smaller distances. Small-scale (approximately 1 kilometer) spatial variability in ozone is important because humans experience these small scales on a daily basis. Using low-cost, next-generation air quality monitors ("pods") developed at the University of Colorado-Boulder, we assessed small-scale spatial variability of surface ozone in Boulder, Colorado. This was done by placing clusters of 4-5 pods within approximately 1 kilometer of each other at specific sites in the city of Boulder. We collected data at two sites: one on the University of Colorado-Boulder campus (i.e., an urban site) and one outside of the city (i.e., a rural site). Pods were left in their positions for one to two weeks allowing for observation of ozone trends. As expected the typical diurnal trend was observed; however, further analysis revealed differences between these daily trends. Data collected by the pods allows for better understanding of small-scale spatial variability of surface ozone and how this may be driven by nearby sources.

  10. Colorado Plateau magmatism and uplift by warming of heterogeneous lithosphere.

    2009-06-18

    The forces that drove rock uplift of the low-relief, high-elevation, tectonically stable Colorado Plateau are the subject of long-standing debate. While the adjacent Basin and Range province and Rio Grande rift province underwent Cenozoic shortening followed by extension, the plateau experienced approximately 2 km of rock uplift without significant internal deformation. Here we propose that warming of the thicker, more iron-depleted Colorado Plateau lithosphere over 35-40 Myr following mid-Cenozoic removal of the Farallon plate from beneath North America is the primary mechanism driving rock uplift. In our model, conductive re-equilibration not only explains the rock uplift of the plateau, but also provides a robust geodynamic interpretation of observed contrasts between the Colorado Plateau margins and the plateau interior. In particular, the model matches the encroachment of Cenozoic magmatism from the margins towards the plateau interior at rates of 3-6 km Myr(-1) and is consistent with lower seismic velocities and more negative Bouguer gravity at the margins than in the plateau interior. We suggest that warming of heterogeneous lithosphere is a powerful mechanism for driving epeirogenic rock uplift of the Colorado Plateau and may be of general importance in plate-interior settings.

    2006-01-01

    Updated proxy reconstructions of water year (October-September) streamflow for four key gauges in the Upper Colorado River Basin were generated using an expanded tree ring network and longer calibration records than in previous efforts. Reconstructed gauges include the Green River at Green River, Utah; Colorado near Cisco, Utah; San Juan near Bluff, Utah; and Colorado at Lees Ferry, Arizona. The reconstructions explain 72-81% of the variance in the gauge records, and results are robust across several reconstruction approaches. Time series plots as well as results of cross-spectral analysis indicate strong spatial coherence in runoff variations across the subbasins. The Lees Ferry reconstruction suggests a higher long-term mean than previous reconstructions but strongly supports earlier findings that Colorado River allocations were based on one of the wettest periods in the past 5 centuries and that droughts more severe than any 20th to 21st century event occurred in the past.

    Wakeling, Brian F.; Sisk, Thomas D.

    2010-01-01

    Roughly centered on the Four Corners region of the southwestern United States, the Colorado Plateau covers some 130,000 square miles of sparsely vegetated plateaus, mesas, canyons, arches, and cliffs in Arizona, Utah, Colorado, and New Mexico. With elevations ranging from 3,000 to 14,000 feet, the natural systems found within the plateau are dramatically varied, from desert to alpine conditions. This book focuses on the integration of science and resource management issues in this unique and highly varied environment. Broken into three subsections, this volume addresses conservation biology, biophysical resources, and inventory and monitoring concerns. The chapters range in content, addressing conservation issues–past, present, and future–on the Colorado Plateau, measurement of human impacts on resources, grazing and wildland-urban interfaces, and tools and methods for monitoring habitats and species. An informative read for people interested in the conservation and natural history of the region, the book will also serve as a valuable reference for those people engaged in the management of cultural and biological resources of the Colorado Plateau, as well as scientists interested in methods and tools for land and resource management throughout the West.

    The Colorado River Basin Water Supply & Demand Study (Study), part of the Basin Study Program under the Department of the Interior's WaterSMART Program, is being conducted by the Bureau of Reclamation and agencies representing the seven Colorado River Basin States. The purpose of the Study is to assess future water supply and demand imbalances in the Colorado River Basin over the next 50 years and develop and evaluate options and strategies to resolve those imbalances. The Study is being conducted over the period from January 2010 to September 2012 and contains four major phases: Water Supply Assessment, Water Demand Assessment, System Reliability Analysis, and Development and Evaluation of Opportunities for balancing supply and demand. To address the considerable amount of uncertainty in projecting the future state of the Colorado River system, the Study has adopted a scenario planning approach that has resulted in four water supply scenarios and up to six water demand scenarios. The water supply scenarios consider hydrologic futures derived from the observed historical and paleo-reconstructed records as well as downscaled global climate model (GCM) projections. The water demand scenarios contain differing projections of parameters such as population growth, water use efficiency, irrigated acreage, and water use for energy that result in varying projections of future demand. Demand for outdoor municipal uses as well as agricultural uses were adjusted based on changing rates of evapotranspiration derived from downscaled GCM projections. Water supply and demand scenarios are combined through Reclamation's long-term planning model to project the effects of future supply and demand imbalances on Colorado River Basin resources. These projections lend to an assessment of the effectiveness of a broad range of options and strategies to address future imbalances.

    Construction and operation of Glen Canyon Dam has dramatically impacted the flow of the Colorado River through Glen, Marble, and Grand Canyons. Extremes in both streamflow and water temperature have been suppressed by controlled releases from the dam. Trapping of sediment in Lake Powell, the reservoir formed by Glen Canyon Dam, has also dramatically reduced the supply of suspended sediment entering the system. These changes have altered the riverine ecosystem and the habitat of native species, including fish such as the endangered humpback chub (Gila cypha). Most native fish are adapted to seasonally warm water, and the continuous relatively cold water released by the dam is one of the factors that is believed to limit humpback chub growth and survival. While average mainstem temperatures in the Colorado River are well documented, there is limited understanding of temperatures in the nearshore environments that fish typically occupy. Four nearshore geomorphic unit types were studied between the confluence of the Colorado and Little Colorado Rivers and Lava Canyon in the summer and fall of 2010, for study periods of 10 to 27 days. Five to seven sites were studied during each interval. Persistent thermal gradients greater than the 0.2 °C accuracy of the instruments were not observed in any of the sampled shoreline environments. Temperature gradients between the shoreline and mainstem on the order of 4 °C, believed to be important to the habitat-seeking behavior of native or nonnative fishes, were not detected.

Con el fin de caracterizarlas en época climática seca, en función del efecto en los cambios en estas variables y la profundidad, sobre su estructura, se midieron éstas variables estructurales en 15 estaciones de la plataforma continental de la Alta y Media Guajira situadas en uno de los tres siguientes intervalos de profundidad: somero (0-2 m, medio (2-4 m y profundo (>4 m. Mediante cuadrantes de 50 x 50 cm se determinó la cobertura de T. testudinum; en subcuadrantes de 20 x 20 cm se determinó la densidad de vástagos y en subcuadrantes de 20 x 10 cm se tomaron muestras para biomasa foliar, peso de epífitos, pastoreo y área foliar. Además, entre marzo y abril del 2006 se realizaron mediciones de producción y crecimiento foliar en Puerto Warreo (bahía Portete y el Cabo de la Vela. Los resultados obtenidos demostraron que la profundidad afectó el comportamiento de las praderas, observándose un mayor desarrollo en las praderas someras, reflejado en el incremento en la densidad foliar, densidad de vástagos, biomasa foliar, biomasa total, área foliar e índice de área foliar. Otros factores ambientales que también explicaron este comportamiento fueron la intensidad de la luz, el sustrato y la ubicación geográfica ya que las praderas con protección de bahía o ensenada, con alto contenido de
    materia orgánica y con mayor proporción de sedimentos finos fueron más exuberantes. La producción primaria,

    Full Text Available Este artículo contribuye a analizar el sistema de movilidad a través de enclaves estratégicos como son los lugares turísticos, espejos de la globalización. Los lugares turísticos no existen sino a través de los flujos de personas: movimientos variados y complejos entre migraciones y turismo. En el contexto del control de las fronteras Norte-Sur, los lugares turísticos emergentes, situados en los márgenes de las regiones más ricas, representan quizás una oportunidad para bordear las fronteras regionales. A través del análisis de la movilidad en el espacio caribeño, las viejas categorías utilizadas para describir los tipos de desplazamientos muestran sus límites de cara a la complejidad de los flujos y de las crecientes interacciones. Seguirá un microanálisis a la escala de la isla de la Martinica que permite abrir una reflexión sobre los aspectos sociales de esta movilidad e interrogarse sobre las cuestiones en juego en torno a las fronteras, nuevas y antiguas, políticas y socioespaciales.This paper contributes to the analysis of the mobilities’ system throughout strategic sites which are the tourist places, a mirror of globalisation. The tourist places only exist through human flows: varied and complex flows between migrations and tourism. In the context of North-South borders’ control the emerging tourist places located at the margins of the richest regions sometimes represent an opportunity in order to bypass the regional borders. Across the analysis of mobilities in the Caribbean area, the old categories used in order to describe the type of movement show their limits in face of the complex flows of growing interactions. Therefore a microanalysis of the Martinique Island allows us to start pondering over the social aspects of the afore-mentioned mobilities and the stakes and interests as regard the old and new political and socio-spatial borders.

    en San Andrés isla, Caribe colombiano. Las tasas de descomposición de Rhizophora mangle (mangle rojo,
    Laguncularia racemosa (mangle blanco y Avicennia germinans (mangle negro fueron medidas en bolsas tipo
    malla. Algunas bolsas fueron dispuestas bajo el suelo, otras sumergidas en el agua, y otras sobre la superficie
    del suelo. Dos humedales del estudio fueron de borde y uno de tipo interno. Algunos factores fisico-químicos que influyen sobre la descomposición de la materia orgánica vegetal fueron evaluados. El modelo de regresión que mejor de ajustó al comportamiento de descomposición fue el simple de raíz cuadrada. La interacción del tiempo con factores bióticos y abióticos determinó la perdida de biomasa foliar. Las mayores tasas de degradación se obtuvieron en humedales de borde; microambientes acuáticos y edáficos húmedos; sobre la especie A. germinans; y en los lugares con macrofauna consumidora asociada. En las etapas tempranas de descomposición
    se presentó la mayor velocidad de degradación. En general, el menor porcentaje medio de biomasa remanente después de seis semanas de incubación lo presentó A. germinans (35%, respecto a R. mangle (44% y L. racemosa (51%. La pedogénesis en San Andrés isla es autóctona, y reconocer el aporte de la necromasa

    RESUMEN Objetivo Mostrar, a través de un diagnóstico en América Latina y el Caribe, el panorama legislativo y curricular sobre sexualidad y prevención contra el virus de inmunodeficiencia humana (VIH) en el ámbito escolar, contrastándolo con los comportamientos sexuales reportados en encuestas demográficas y de salud. Métodos En mayo de 2008 se realizó, con el apoyo del Fondo de Población de las Naciones Unidas (UNFPA), una encuesta a informantes clave en 34 países de la Región. El cuestionario autoaplicado solicitó información sustantiva de agentes de las diferentes partes interesadas, como ministerios de educación y de salud, sobre los programas de prevención contra el VIH/Sida que se están aplicando en las escuelas. Resultados Respondieron a la encuesta 27 países que representan 95,5% de la población objetivo (6 a 18 años de edad). La mayoría de los países informó tener al menos un libro de texto o un capítulo específico para enseñar los temas de educación sobre sexualidad y prevención del VIH. En la escuela secundaria se cubren la mayor parte de los temas pertinentes relevantes para la educación sobre sexualidad, pero no todos. Por ejemplo, el problema de la discriminación por orientación o preferencia sexual no se incluye en los programas escolares. Conclusiones El material educativo sobre sexualidad debe ser revisado y actualizado periódicamente de modo que refleje los avances en los temas y en la forma de tratar los contenidos. En cada país el currículo debe abordar el tema del respeto a la diversidad sobre orientación, preferencia e identidad sexuales, y en particular el manejo apropiado de la educación para prevenir infecciones de transmisión sexual (ITS) en hombres que tienen sexo con hombres. Los esfuerzos de evaluación de la efectividad de los programas deben contemplar desenlaces tales como marcadores biológicos (incidencia y prevalencia de ITS y embarazo) y no únicamente indicadores de conocimiento y

    Spanning parts of the seven states, of Arizona, California, Colorado, New Mexico, Nevada, Utah, and Wyoming, the Colorado River is one of the most critical sources of water in the western United States. Colorado River allocations exceed the long-term supply and since the 1950s, there have been a number of years when the annual water use in the Colorado River Basin exceeded the yield. The Basin is entering its second decade of drought conditions which brings challenges that will only be compounded if projections of climate change are realized. It was against this backdrop that the Colorado River Basin Water Supply and Demand Study was conducted. The Study's objectives are to define current and future imbalances in the Basin over the next 50 years and to develop and analyze adaptation and mitigation strategies to resolve those imbalances. Long-term planning in the Basin involves the integration of uncertainty with respect to a changing climate and other uncertainties such as future demand and how policies may be modified to adapt to changing reliability. The Study adopted a scenario planning approach to address this uncertainty in which thousands of scenarios were developed to encompass a wide range of plausible future water supply and demand conditions. Using Reclamation's long-term planning model, the Colorado River Simulation System, the reliability of the system to meet Basin resource needs under these future conditions was projected both with and without additional future adaptation strategies in place. System reliability metrics were developed in order to define system vulnerabilities, the conditions that lead to those vulnerabilities, and sign posts to indicate if the system is approaching a vulnerable state. Options and strategies that reduce these vulnerabilities and improve system reliability were explored through the development of portfolios. Four portfolios, each with different management strategies, were analyzed to assess their effectiveness at

Para ello, durante los últimos cinco años, se han realizado intensas prospecciones de campo en aquellas áreas donde previamente se había documentado la presencia de una especie de Cneorum (identificada inicialmente como C. trimerum y como C. tricoccon posteriormente en Sierra Maestra, Cuba. Además, se ha revisado material de herbario y bibliografía diversa. La presencia de antiguos asentamientos de cafeteros franceses en las localidades donde se colectó esta especie, junto con el hecho de presentar propiedades medicinales (en hojas y frutos, hace posible que fuera introducida intencionadamente en Cuba desde el sur de Francia por los propios colonos a mediados del siglo XIX. Concluimos que esta especie no se encuentra ya en Cuba, y creemos que nunca llegó a establecerse y naturalizarse en la isla. Además, debido a un sutil parecido en las hojas, y a identificaciones realizadas a partir de materiales de herbarios, se ha estado confundiendo, hasta muy recientemente, C. tricoccon con Schoepfia stenophylla Urb. (Olacaceae, un endemismo amenazado y sobre el que ya hay actualmente un plan de conservación in situ. Dicha confusión de especies ha contribuido a mantener y transmitir diferentes errores a lo largo de la historia taxonómica sobre la supuesta presencia de Cneorum en Cuba, y por tanto, de una aparente conexión de las floras mediterráneas y caribeñas en relación a Cneoraceae.

    The geology of the wide shelves surrounding the South Atlantic is closely linked to the kinematics and history of the opening of the ocean. However, several wide sedimentary basins, which developed along the margins show peculiarities that are not yet understood in the context of the evolution of the South Atlantic. The Colorado Basin, a wide sedimentary basin on the broad shelf of Argentina, extends in EW direction. The basin's evolution oblique or orthogonal to the continent-ocean boundary indicates that it is not a product of simple progressive extension and crustal thinning. In addition a basement high, paralleling the continental margin and separating the Colorado Basin from the deep-sea basin is a common interpretation. These findings are hardly in accordance with the idea that the Colorado Basin is an extensional basin that developed in conjunction with the early E-W opening phase of the South Atlantic in the Late Jurassic/Early Cretaceous. The composition, type, and structure of the basement, key points for the evaluation of the basins evolution, are widely speculative. In this context multichannel seismic reflection data from the Argentine Shelf and a 665-km-long onshore-offshore refraction profile, running across the Colorado Basin onto the coast are discussed in combination with gravity data. The stratigraphy for the sedimentary successions was adopted from the literature and the reflection seismic marker horizons formed besides the interval velocities the input for the starting model for refraction seismic traveltime modelling. The modelling strategy was an iterative procedure between refraction seismic traveltime and gravity modelling. The preparation of the density models was coarsely orientated on published velocity-density relations. The modelling results are in favour of a continuation of the main onshore geological features beneath the sedimentary infill of the Colorado Basin. We interpret the basement along the line from west to east as offshore

    Full Text Available Colorado's voucher law was declared unconstitutional by the Colorado Supreme Court on June 28, 2004. Voucher supporters have begun drafting revised legislation designed to address the legal problem. This article calls into question the key financial claim of revenue neutrality'a claim that was central to the promotion and passage of the departing voucher law. The author concludes that the voucher law was not revenue neutral, even though it attempts to exclude from eligibility those children already enrolled in private schools. In fact, this law, as well as any revised law with similar eligibility provisions, would actually cost taxpayers an additional $10 million per year once fully implemented because the eligibility provision provides little more than a short-term damper on the law's long-term fiscal impact.

    Breeding densities and migration periods of Common Snipe in Colorado were investigated in 1974-75. Sites studied were near Fort Collins and in North Park, both in north central Colorado; in the Yampa Valley in northwestern Colorado; and in the San Luis Valley in south central Colorado....Estimated densities of breeding snipe based on censuses conducted during May 1974 and 1975 were, by region: 1.3-1.7 snipe/ha near Fort Collins; 0.6 snipe/ha in North Park; 0.5-0.7 snipe/ha in the Yampa Valley; and 0.5 snipe/ha in the San Luis Valley. Overall mean densities were 06 and 0.7 snipe/ha in 1974 and 1975 respectively. On individual study sites, densities of snipe ranged from 0.2 to 2.1 snipe/ha. Areas with shallow, stable, discontinuous water levels, sparse, short vegetation, and soft organic soils had the highest densities.....Twenty-eight nests were located having a mean clutch size of 3.9 eggs. Estimated onset of incubation ranged from 2 May through 4 July. Most nests were initiated in May.....Spring migration extended from late March through early May. Highest densities of snipe were recorded in all regions during l&23 April. Fall migration was underway by early September and was completed by mid-October with highest densities occurring about the third week in September. High numbers of snipe noted in early August may have been early migrants or locally produced juveniles concentrating on favorable feeding areas.

    In 1923, America paid close attention, via special radio broadcasts, newspaper headlines, and cover stories in popular magazines, as a government party descended the Colorado to survey Grand Canyon. Fifty years after John Wesley Powell's journey, the canyon still had an aura of mystery and extreme danger. At one point, the party was thought lost in a flood. Something important besides adventure was going on. Led by Claude Birdseye and including colorful characters such as early river-runner E...

    The historical distribution of Gunnison Sage-Grouse (Centrocercus minimus) in Colorado is described based on published literature, observations, museum specimens, and the known distribution of sagebrush (Artemisia spp.). Historically, Gunnison Sage-Grouse were widely but patchily distributed in up to 22 counties in south-central and southwestern Colorado. The historical distribution of this species was south of the Colorado-Eagle river drainages primarily west of the Continental Divide. Potential contact areas with Greater Sage-Grouse (C. urophasianus) were along the Colorado-Eagle river system in Mesa, Garfield, and Eagle counties, west of the Continental Divide. Gunnison Sage-Grouse historically occupied habitats that were naturally highly fragmented by forested mountains and plateaus/mesas, intermountain basins without robust species of sagebrush, and river systems. This species adapted to use areas with more deciduous shrubs (i.e., Quercus spp., Amelanchier spp., Prunus spp.) in conjunction with sagebrush. Most areas historically occupied were small, linear, and patchily distributed within the overall landscape matrix. The exception was the large intermountain basin in Gunnison, Hinsdale, and Saguache counties. The documented distribution east of the Continental Divide within the large expanse of the San Luis Valley (Alamosa, Conejos, Costilla, and Rio Grande counties) was minimal and mostly on the eastern, northern, and southern fringes. Many formerly occupied habitat patches were vacant by the mid 1940s with extirpations continuing to the late 1990s. Counties from which populations were recently extirpated include Archuleta and Pitkin (1960s), and Eagle, Garfield, Montezuma, and Ouray (1990s).

    In the Rocky Mountains of Colorado, major highways are often constructed in stream valleys. In the event of a vehicular accident involving hazardous materials, the close proximity of highways to the streams increases the risk of contamination entering the streams. Recent population growth has contributed to increased traffic volume along Colorado highways and has resulted in increased movement of hazardous materials, particularly along Interstate 70. Gore Creek and its major tributary, Black Gore Creek, are vulnerable to such contamination from vehicular accidents along Interstate 70. Gore Creek, major tributary of the Eagle River, drains approximately 102 square miles, some of which has recently undergone significant urban development. The headwaters of Gore Creek originate in the Gore Range in the eastern part of the Gore Creek watershed. Gore Creek flows west to the Eagle River. Beginning at the watershed boundary on Vail Pass, southeast of Vail Ski Resort, Interstate 70 parallels Black Gore Creek and then closely follows Gore Creek the entire length of the watershed. Interstate 70 crosses Gore Creek and tributaries 20 times in the watershed. In the event of a vehicular accident involving a contaminant spill into Gore Creek or Black Gore Creek, a stepwise procedure has been developed for water-resource managers to estimate traveltimes of the leading edge and peak concentration of a conservative contaminant. An example calculating estimated traveltimes for a hypothetical contaminant release in Black Gore Creek is provided. Traveltime measurements were made during May and September along Black Gore Creek and Gore Creek from just downstream from the Black Lakes to the confluence with the Eagle River to account for seasonal variability in stream discharge. Fluorometric dye injection of rhodamine WT and downstream dye detection by fluorometry were used to measure traveltime characteristics of Gore Creek and Black Gore Creek. During the May traveltime measurements

  9. Cost effectiveness of the 1993 Model Energy Code in Colorado

    1995-06-01

    This report documents an analysis of the cost effectiveness of the Council of American Building Officials` 1993 Model Energy Code (MEC) building thermal-envelope requirements for single-family homes in Colorado. The goal of this analysis was to compare the cost effectiveness of the 1993 MEC to current construction practice in Colorado based on an objective methodology that determined the total life-cycle cost associated with complying with the 1993 MEC. This analysis was performed for the range of Colorado climates. The costs and benefits of complying with the 1993 NIEC were estimated from the consumer`s perspective. The time when the homeowner realizes net cash savings (net positive cash flow) for homes built in accordance with the 1993 MEC was estimated to vary from 0.9 year in Steamboat Springs to 2.4 years in Denver. Compliance with the 1993 MEC was estimated to increase first costs by $1190 to $2274, resulting in an incremental down payment increase of $119 to $227 (at 10% down). The net present value of all costs and benefits to the home buyer, accounting for the mortgage and taxes, varied from a savings of $1772 in Springfield to a savings of $6614 in Steamboat Springs. The ratio of benefits to costs ranged from 2.3 in Denver to 3.8 in Steamboat Springs.

  10. Geothermal resource assessment of western San Luis Valley, Colorado

    1983-01-01

    The Colorado Geological Survey initiated and carried out a fully integrated assessment program of the geothermal resource potential of the western San Luis Valley during 1979 and 1980. The San Luis Valley is a large intermontane basin located in southcentral Colorado. While thermal springs and wells are found throughout the Valley, the only thermal waters found along the western part of the Valley are found at Shaw Warm Springs which is a relatively unused spring located approximately 6 miles (9.66 km) north of Del Norte, Colorado. The waters at Shaws Warm Spring have a temperature of 86 F (30 C), a discharge of 40 gallons per minute and contain approximately 408 mg/l of total dissolved solids. The assessment program carried out din the western San Luis Valley consisted of: soil mercury geochemical surveys; geothermal gradient drilling; and dipole-dipole electrical resistivity traverses, Schlumberger soundings, Audio-magnetotelluric surveys, telluric surveys, and time-domain electro-magnetic soundings and seismic surveys. Shaw Warm Springs appears to be the only source of thermal waters along the western side of the Valley. From the various investigations conducted the springs appear to be fault controlled and is very limited in extent. Based on best evidence presently available estimates are presented on the size and extent of Shaw Warm Springs thermal system. It is estimated that this could have an areal extent of 0.63 sq. miles (1.62 sq. km) and contain 0.0148 Q's of heat energy.

    Since the advent of plate tectonics, it has been speculated that the northern extension of the East Pacific Rise, specifically its mantle source, has been over-ridden by the North American Plate in the last 30 Myrs. Consequently, it has also been postulated that the opening of the Gulf of California, the extension in the Basin and Range province, and the uplift of the Colorado Plateau are the resulting continental expressions of the over-ridden mantle source of the East Pacific Rise. However, only qualitative models based solely on surface observations and heuristic, simplified conceptions of mantle convection have been used in support or against this hypothesis. We introduce a quantitative model of mantle convection that reconstructs the detailed motion of a warm mantle upwelling over the last 30 Myrs and its relative advance towards the interior of the southwestern USA. The onset and evolution of the crustal uplift in the central Basin and Range province and the Colorado Plateau is determined by tracking the topographic swell due to this mantle upwelling through time. We show that (1) the extension and magmatism in the central Basin and Range province between 25 and 10 Ma coincides with the reconstructed past position of this focused upwelling, and (2) the southwestern portion of the Colorado Plateau experienced significant uplift between 10 Ma and 5 Ma that progressed towards the northeastern portion of the plateau. These uplift estimates are consistent with a young, ca. 6 Ma, Grand Canyon model and the recent commencement of mafic magmatism.

    On June 1, 2014 (UTC) a magnitude 3.2 earthquake occurred east of the town of Greeley, Colorado. The earthquake was widely felt, with reports from Boulder and Golden, over 60 miles away from the epicenter. The location of the earthquake in a region long considered aseismic but now the locus of active oil and gas production prompted the question of whether this was a natural or induced earthquake. Several classic induced seismicity cases hail from Colorado, including the Rocky Mountain Arsenal earthquakes in the 1960s and the Paradox Valley earthquakes in western Colorado. In both cases the earthquakes were linked to wastewater injection. The Greeley earthquake epicenter was close to a Class II well that had been injecting waste fluid into the deepest sedimentary formation of the Denver Basin at rates as high as 350,000 barrels/month for less than a year. The closest seismometers to the June 1 event were more than 100 km away, necessitating deployment of a local seismic network for detailed study. IRIS provided six seismometers to the University of Colorado which were deployed starting within 3 days of the mainshock. Telemetry at one site allowed for real time monitoring of the ongoing seismic sequence. Local media interest was extremely high with speculation that the earthquake was linked to the oil and gas industry. The timetable of media demand for information provided some challenges given the time needed for data collection and analysis. We adopted a policy of open data and open communication with all interested parties, and made proactive attempts to provide information to industry and regulators. After 3 weeks of data collection and analysis, the proximity and timing of the mainshock and aftershocks to the C4A injection well, along with a sharp increase in seismicity culminating in an M 2.6 aftershock, led to a decision by the Colorado Oil and Gas Corporation Commission (COGCC) to recommend a temporary halt to injection at the C4A injection well. This was the

    International Nuclear Information System (INIS)

    As required by the Romer-Twining Agreement of 1990, the US Department of Energy (DOE) has prepared this annual economic impact study for the state of Colorado. This report assesses the economic impacts related to the DOE Uranium Mill Tailings Remedial Action (UMTRA) Project in Colorado during the state fiscal year (FY) between 1 July 1994 and 30 June 1995. To estimate net economic benefit, employment, salaries and wages, and other related economic benefits are discussed, quantified, and then compared to the state's 10 percent share of the remedial action costs. Actual data obtained from sites currently undergoing remedial action were used as the basis for analyses. If data were not available, estimates were used to derive economic indicators. This study describes the types of employment associated with the UMTRA Project and estimates of the numbers of people employed by UMTRA Project subcontractors in Colorado during state FY 1995. Employment totals are reported in estimated average annual jobs; however, the actual number of workers at the site fluctuates depending on weather and on the status of remedial action activities. In addition, the actual number of people employed on the Project during the year may be higher than the average annual employment reported due to the temporary nature of some of the jobs

    New 1:24,000-scale geologic mapping along the Interstate-70 urban corridor in western Colorado, in support of the USGS Central Region State/USGS Cooperative Geologic Mapping Project, is contributing to a more complete understanding of the stratigraphy, structure, tectonic evolution, and hazard potential of this rapidly developing region. The 1:24,000-scale Frisco quadrangle is near the headwaters of the Blue River and straddles features of the Blue River graben (Kellogg, K.S., 1999, Neogene basins of the northern Rio Grande rift?partitioning and asymmetry inherited from Laramide and older uplifts: Tectonophysics, v. 305, p. 141-152.), part of the northernmost reaches of the Rio Grande rift, a major late Oligocene to recent zone of extension that extends from Colorado to Mexico. The Williams Range thrust fault, the western structural margin of the Colorado Front Range, cuts the northeastern corner of the quadrangle. The oldest rocks in the quadrangle underlie the Tenmile Range and include biotite-sillimanite schist and gneiss, amphibolite, and migmatite that are intruded by granite inferred to be part of the 1,667-1,750 Ma Routt Plutonic Suite (Tweto, Ogden, 1987, Rock units of the Precambrian- basement in Colorado: U.S. Geological Survey Professional Paper 1321-A, 54 p.). The oldest sedimentary unit is the Pennsylvanian Maroon Formation, a sequence of red sandstone, conglomerate, and interbedded shale. The thickest sequence of sedimentary rocks is Cretaceous in age and includes at least 500 m of the Upper Cretaceous Pierre Shale. The sedimentary rocks are intruded by sills and dikes of dacite porphyry sills of Swan Mountain, dated at 44 Ma (Marvin, R.F., Mehnert, H.H., Naeser, C.W., and Zartman, R.E., 1989, U.S. Geological Survey radiometric ages, compilation ?C??Part five?Colorado, Montana, Utah, and Wyoming: Isochron/West, no. 53, p. 14-19.

    The Argentine margin presents a strong segmentation with considerable strike-slip movements along the fracture zones. We focus on the volcanic segment (between the Salado and Colorado transfer zones), which is characterized by seaward dipping reflectors (SDR) all along the ocean-continent transition [e.g. Franke et al., 2006; Gladczenko et al., 1997; Hinz et al., 1999]. The segment is structured by E-W trending basins, which differs from the South African margin basins and cannot be explained by classical models of rifting. Thus the study of the relationship between the basins and the Argentine margin itself will allow the understanding of their contemporary development. Moreover the comparison of the conjugate margins suggests a particular evolution of rifting and break-up. We firstly focus on the Colorado Basin, which is thought to be the conjugate of the well studied Orange Basin [Hirsch et al., 2009] at the South African margin [e.g. Franke et al., 2006]. This work presents results of a combined approach using seismic interpretation and structural, isostatic and thermal modelling highlighting the structure of the crust. The seismic interpretation shows two rift-related discordances: one intra syn-rift and the break-up unconformity. The overlying sediments of the sag phase are less deformed (no sedimentary wedges) and accumulated before the generation of oceanic crust. The axis of the Colorado Basin trends E-W in the western part, where the deepest pre-rift series are preserved. In contrast, the basin axis turns to a NW-SE direction in its eastern part, where mainly post-rift sediments accumulated. The most distal part reaches the margin slope and opens into the oceanic basin. The general basin direction is almost orthogonal to the present-day margin trend. The most frequent hypothesis explaining this geometry is that the Colorado Basin is an aborted rift resulting from a previous RRR triple junction [e.g. Franke et al., 2002]. The structural interpretation

  5. Diagnosing Possible Anthropogenic Contributions to Colorado Floods in September 2013.

    Science.gov (United States)

    Pall, P.; Patricola, C. M.; Wehner, M. F.; Stone, D. A.

    2015-12-01

    Unusually heavy rainfall occurred over the Colorado Front Range during the second week of September 2013, with record or near-record totals recorded in several locations. It was associated predominantly with a stationary large-scale weather pattern (akin to the North American Monsoon, which occurs earlier in the year) that drove a strong plume of deep moisture inland from the Gulf of Mexico and eastern tropical Pacific towards the Front Range foothills. The resulting floods across the South Platte River basin impacted several thousands of people and many homes, roads, and businesses. A recent study using observational-based re-analysis to drive the regional WRF model finds that, given very little change in the large-scale weather pattern, there is an increase in atmospheric water vapour over northeast Colorado under anthropogenic climate warming, with a positive dynamical feedback drawing in moisture from further afield. This leads to a substantial increase in the magnitude and odds of heavy rainfall occurring over northeast Colorado during the rainy week of September 2013. Here we develop this work by including a hydrological modelling component in order to investigate any anthropogenic influence on the actual flood magnitude and occurrence across the South Platte basin during that time. We use WRF precipitation output from the aforementioned study - in both anthropogenic and non-anthropogenic configurations for September 2013 - to drive the recently developed high-resolution WRF-Hydro model over the basin and generate river runoff. Thus by comparing changes in runoff under the anthropogenic / non-anthropogenic driving conditions we assess any influence on the magnitude and odds of flood occurrence. Integral to this, we test the sensitivity of our results to hydrological parameters, such as infiltration, base flow, and land use/cover.

  6. Opportunities to protect instream flows in Colorado and Wyoming

    Science.gov (United States)

    Trembly, Terrence L.

    1987-01-01

    This document combines the efforts of several individuals, agencies, and organizations toward a common objective: the identification, description, and preliminary evaluation of promising opportunities for protecting instream uses of water under existing laws in Colorado and Wyoming. This report is intended for the use of State and Federal planning and management personnel who need an overview of potential opportunities for preserving instream flows. It is not intended to replace or challenge the advice of agency counsel, nor it is written to provide legal advice. Instead, it is designed as a guide for the person trying to find his or her way among sometimes bewildering State statues and administrative practices. This report is not, and should not be taken as, official policy or prediction of future actions by any agency. It is simply a summary of some potential opportunities for protecting instream uses. Toward these objectives, the U.S. Fish and Wildlife Service, through its Water Resources Analysis Project, contracted in 1977 with Richard Dewsnup and Dallin Jensen to identify available strategies under State and Federal laws, interstate compacts, and water quality laws. A second firm, Enviro Control, Inc., was contracted to evaluate the most promising strategies. Two of the resulting documents were Instream Flow Strategies for Colorado and Instream Flow Strategies for Wyoming, which have been revised, updated, and combined in this report. Discussion of instream flow programs ad opportunities for each State--Colorado and Wyoming-- are written so that each report can be read independently, with minimal cross referencing from one State report to another.

    This dataset represents an update to U.S. Geological Survey Data Series 597. Locations and attributes of wind turbines in Colorado, 2009 (available at http://pubs.usgs.gov/ds/597/). This updated Colorado wind turbine Data Series provides geospatial data for all 1,204 wind turbines established within the State of Colorado as of September 2011, an increase of 297 wind turbines from 2009. Attributes specific to each turbine include: turbine location, manufacturer and model, rotor diameter, hub height, rotor height, potential megawatt output, land ownership, county, and development status of the wind turbine. Wind energy facility data for each turbine include: facility name, facility power capacity, number of turbines associated with each facility to date, facility developer, facility ownership, and year the facility went online. The locations of turbines are derived from 1-meter true-color aerial photographs produced by the National Agriculture Imagery Program (NAIP); the photographs have a positional accuracy of about ±5 meters. Locations of turbines constructed during or prior to August 2009 are based on August 2009 NAIP imagery and turbine locations constructed after August 2009 were based on September 2011 NAIP imagery. The location of turbines under construction during September 2011 likely will be less accurate than the location of existing turbines. This data series contributes to an Online Interactive Energy Atlas developed by the U.S. Geological Survey (http://my.usgs.gov/eerma/). The Energy Atlas synthesizes data on existing and potential energy development in Colorado and New Mexico and includes additional natural resource data layers. This information may be used by decisionmakers to evaluate and compare the potential benefits and tradeoffs associated with different energy development strategies or scenarios. Interactive maps, downloadable data layers, comprehensive metadata, and decision-support tools also are included in the Energy Atlas. The format of

  10. Environmental Assessment Expanded Ponnequin Wind Energy Project Weld County, Colorado

    Energy Technology Data Exchange (ETDEWEB)

    N/A

    1999-03-02

    The U.S.Department of Energy (DOE) has considered a proposal from the State of Colorado, Office of Energy Conservation (OEC), for funding construction of the Expanded Ponnequin Wind Project in Weld County, Colorado. OEC plans to enter into a contracting arrangement with Public Service Company of Colorado (PSCO) for the completion of these activities. PSCo, along with its subcontractors and business partners, are jointly developing the Expanded Ponnequin Wind Project. DOE completed an environmental assessment of the original proposed project in August 1997. Since then, the geographic scope and the design of the project changed, necessitating additional review of the project under the National Environmental Policy Act. The project now calls for the possible construction of up to 48 wind turbines on State and private lands. PSCo and its partners have initiated construction of the project on private land in Weld County, Colorado. A substation, access road and some wind turbines have been installed. However, to date, DOE has not provided any funding for these activities. DOE, through its Commercialization Ventures Program, has solicited applications for financial assistance from state energy offices, in a teaming arrangement with private-sector organizations, for projects that will accelerate the commercialization of emerging renewable energy technologies. The Commercialization Ventures Program was established by the Renewable Energy and Energy Efficiency Technology Competitiveness Act of 1989 (P.L. 101-218) as amended by the Energy Policy Act of 1992 (P.L. 102-486). The Program seeks to assist entry into the marketplace of newly emerging renewable energy technologies, or of innovative applications of existing technologies. In short, an emerging renewable energy technology is one which has already proven viable but which has had little or no operational experience. The Program is managed by the Department of Energy, Office of Energy Efficiency and Renewable Energy. The

  12. Solar energy system economic evaluation for Colt Pueblo, Pueblo, Colorado

    Science.gov (United States)

    1980-01-01

    The Solar Energy System is not economically beneficial under the assumed economic conditions at Pueblo, Colorado; Yosemite, California; Albuquerque, New Mexico; Fort Worth, Texas; and Washington, D.C. Economic benefits from this system depend on decreasing the initial investment and the continued increase in the cost of conventional energy. Decreasing the cost depends on favorable tax treatment and continuing development of solar energy technology. Fuel cost would have to increase drastically while the cost of the system would have to remain constant or decrease for the system to become economically feasible.

  14. An experiment to control nonnative fish in the Colorado River, Grand Canyon, Arizona

    Science.gov (United States)

    Coggins,, Lewis G., Jr.; Yard, Michael D.

    2011-01-01

    The humpback chub (Gila cypha) is an endangered native fish found only in the Colorado River Basin. In Grand Canyon, most humpback chub are found in the Little Colorado River and its confluence with the Colorado River. For decades, however, nonnative rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta), which prey on and compete with native fish, have dominated the Grand Canyon fish community. Between 2003 and 2006, scientists with the U.S. Geological Survey and Arizona Game and Fish Department experimentally removed 23,266 nonnative fish from a 9.4-mile-long reach of the Colorado River near where it joins the Little Colorado River. During the experiment, rainbow trout were reduced by as much as 90% and native fish abundance apparently increased in the reach. Concurrent environmental changes and a decrease in rainbow trout throughout the river make it difficult to determine if the apparent increase in native fish was the result of the experiment.

  15. The temporal and spatial relationship between NDVI and climatological parameters in Colorado

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    This paper describes the spatial and temporal relationship between AVHRR/NDVI (Normalized Difference Vegetation Index) and climatological parameters (temperature and precipitation), which, in some sense, is influenced by topographical factors and land-cover types in Colorado. The correlation coefficients and partial correlation coefficients have been computed pixel by pixel over Colorado in order to analyze the relationship. The temporal variation and correlation of AVHRR/NDVI, temperature and precipitation were analyzed with a sampling method. The study reveals that there exists a close correspondence between monthly NDVI and temperature, which has strong impact from temperature on the changes of NDVI in Colorado. The spatial changes of NDVI are not influenced obviously by the precipitation since these two variables are different from each other in time series in Colorado. The study clearly revealed the spatial variation and its distribution patterns of relationship between NDVI and climatic parameters (temperature and precipitation) in Colorado.

Para ello, se enfatizará en cómo estas propuestas estéticas, basadas en lo abyecto y grotesco, y que se sirven de procedimientos narrativos tanto literarios como audiovisuales, configuran una representación de un Caribe “otro” que se resiste al discurso exotista de lo caribeño y que a la vez legitima el discurso fundacional de violencia y bestialidad. ABSTRACT: The monstrosity and dystopia of Caribbean bodies, behaviors and spaces will be analyzed in relation to the literature of Dominican writers Rita Indiana Hernández and Frank Baez, as well as the recent Cuban film directed by Alexander Brugués. The emphasis will be on how these aesthetic objects -mainly of abject and grotesque nature, and configured by both audiovisual and narrative strategies- represent an "other" Caribbean which resists the exotic cliché while at the same time legitimizing the foundational discourse of violence and brutality.

  18. Annual monitoring report for the Gunnison, Colorado, wetlands mitigation plan

    Energy Technology Data Exchange (ETDEWEB)

    1995-10-01

    The US Department of Energy (DOE) administers the Uranium Mill Tailings Remedial Action (UMTRA) Project to clean up uranium mill tailings and other surface contamination at 24 abandoned uranium mill sites in 10 states. One of these abandoned mill sites is near the town of Gunnison, Colorado; surface remediation and the environmental impacts of remedial action are described in the Gunnison environmental assessment (EA) (DOE, 1992). Remedial action resulted in the elimination of 4.3 acres (ac) 1.7 hectares (ha) of wetlands and mitigation of this loss of wetlands is being accomplished through the enhance of 18.4 ac (7.5 ha) of riparian plant communities in six spring feed areas on Bureau of Land Management (BLM) land. The description of the impacted and mitigation wetlands is provided in the Mitigation and Monitoring Plan for Impacted Wetlands at the Gunnison UMTRA Project Site, Gunnison, Colorado (DOE, 1994), which is attached to the US Army corps of Engineers (USACE) Section 404 Permit. As part of the wetlands mitigation plan, the six mitigation wetlands were fenced in the fall of 1993 to exclude livestock grazing. Baseline of grazed conditions of the wetlands vegetation was determined during the summer of 1993 (DOE, 1994). A 5-year monitoring program of these six sites has been implemented to document the response of vegetation and wildlife to the exclusion of livestock. This annual monitoring report provides the results of the first year of the 5-year monitoring period.

  19. The rural utility response to Colorado's electricity mandates

    International Nuclear Information System (INIS)

    When Colorado voters passed Amendment 37 in 2004, it became the first state to pass a renewable portfolio standard at the ballet box, suggesting broad appeal to harness and pay for renewable energy. While large urban utilities are prepared to make this transition, smaller cities and rural areas, for various financial and scale issues are severely disadvantaged in trying to incorporate more renewable energy sources into their electricity mix. This was evident by the state's support for Amendment 37, which was passed due to strong support in the Denver metro area-representing nearly half of the state's population. Support for the bill was poor in the rest of the state. Nevertheless, in 2007, the state expanded up Amendment 37 by forcing the utilities in rural communities to diversify their electricity mix. This study surveyed the managers at the state's various rural electric cooperatives and municipal utilities in an effort to gage their attitudes concerning: carbon legislation, conservation and efficiency programs, and their plans for making the transition away from fossil fuel generation. - Highlights: → Communities served by rural utilities opposed Colorado's state-wide RPS, but were forced to adhere anyway. → Most rural utilities are very concerned about the economic impacts of trying to diversify their energy portfolios. → Many of these unregulated utilities were already pushing DSM programs to promote conservation and improve efficiency.

    The Colorado wind-turbine data series provides geospatial data for all wind turbines established within the State as of August 2009. Attributes specific to each turbine include: turbine location, manufacturer and model, rotor diameter, hub height, rotor height, potential megawatt output, land ownership, and county. Wind energy facility data for each turbine include: facility name, facility power capacity, number of turbines associated with each facility to date, facility developer, facility ownership, year the facility went online, and development status of wind facility. Turbine locations were derived from August 2009 1-meter true-color aerial photographs produced by the National Agriculture Imagery Program; the photographs have a positional accuracy of about + or - 5 meters. The location of turbines under construction during August 2009 likely will be less accurate than the location of existing turbines. This data series contributes to an Online Interactive Energy Atlas currently (2011) in development by the U.S. Geological Survey. The Energy Atlas will synthesize data on existing and potential energy development in Colorado and New Mexico and will include additional natural resource data layers. This information may be used by decisionmakers to evaluate and compare the potential benefits and tradeoffs associated with different energy development strategies or scenarios. Interactive maps, downloadable data layers, comprehensive metadata, and decision-support tools will be included in the Energy Atlas. The format of the Energy Atlas will facilitate the integration of information about energy with key terrestrial and aquatic resources for evaluating resource values and minimizing risks from energy development.

All dollar amounts used in the study are in year-of-expenditure dollars. The total funding requirement for the State of Colorado for the UMTRA Project is estimated to be $66.8 million, or 10 percent of the remedial action costs for the UMTRA Project in Colorado. The UMTRA Project will generate $487.5 million in gross labor income in Colorado between 1983 and 1996. This includes $54.4 million in state and local tax revenues and $41.2 million in federal individual income tax revenues. The net economic benefit of the UMTRA Project to Colorado is $355.1 million. For every dollar the State of Colorado invests in the UMTRA Project, it will realize $5.32 in gross labor income. The employment impact to the Western Slope region is significant. The UMTRA Project will create a total employment impact of 13,749 fulltime equivalents (FTES) spread over. a period of 13 years in seven site areas. Nearly 100 percent of the labor will be drawn from the local communities. The State of Colorado's Western Slope is anticipated to be minimally impacted by the phaseout of the UMTRA Project. Unlike industries that shut down operations without warning, the UMTRA Project workers, local government, and businesses know the schedule for completion and can consider and prepare for the impact of UMTRA Project conclusion. Further, because the majority of the work force is local, there has not been a significant investment in each community's infrastructure. Any small increases in the infrastructure will not be abandoned at the end of the UMTRA Project due to a marked increase in migration out of the local community

    May and June 2012 were unusually hot and dry in Colorado, which was suffering from a strong drought. A major consequence of this climatic regime was one of the most destructive forest fire seasons in state history, with hundreds of thousands of acres of forest and grassland consumed by flames, hundreds of homes burned, and several lives lost. Many of these fires occurred within range of the newly installed Colorado Lightning Mapping Array (COLMA), which provides high-resolution observations of discharges over a large portion of the state. The COLMA was installed in advance of the Deep Convective Clouds and Chemistry (DC3) project. High-altitude lightning was observed to occur sporadically in the smoke plumes over three major fires that occurred during early summer: Hewlett Gulch, High Park, and Waldo Canyon. Additionally, the Colorado State University CHILL (CSU-CHILL) and Pawnee radars observed the Hewlett Gulch plume electrify with detailed polarimetric and dual-Doppler measurements, and also provided these same measurements for the High Park plume when it was not producing lightning. Meanwhile, local Next Generation Radars (NEXRADs) provided observations of the electrified High Park and Waldo Canyon plumes. All of these plumes also were observed by geostationary meteorological satellites. These observations provide an unprecedented dataset with which to study smoke plume and pyrocumulus electrification. The polarimetric data - low reflectivity, high differential reflectivity, low correlation coefficient, and noisy differential phase - were consistent with the smoke plumes and associated pyrocumulus being filled primarily with irregularly shaped ash particles. Lightning was not observed in the plumes until they reached over 10 km above mean sea level, which was an uncommon occurrence requiring explosive fire growth combined with increased meteorological instability and reduced wind shear. Plume updraft intensification and echo-top growth led the occurrence of

    Teleseismic traveltime data are inverted for mantle Vp and Vs variations beneath a 1400 km long line of broadband seismometers extending from eastern New Mexico to western Utah. The model spans 600 km beneath the moho with resolution of ???50 km. Inversions show a sharp, large-magnitude velocity contrast across the Colorado Plateau-Great Basin transition extending ???200 km below the crust. Also imaged is a fast anomaly 300 to 600 km beneath the NW portion of the array. Very slow velocities beneath the Great Basin imply partial melting and/or anomalously wet mantle. We propose that the sharp contrast in mantle velocities across the western edge of the Plateau corresponds to differential lithospheric modification, during and following Farallon subduction, across a boundary defining the western extent of unmodified Proterozoic mantle lithosphere. The deep fast anomaly corresponds to thickened Farallon plate or detached continental lithosphere at transition zone depths. Copyright 2008 by the American Geophysical Union.

  10. 1996 monitoring report for the Gunnison, Colorado, wetlands mitigation plan

    1996-12-01

    The US Department of Energy (DOE) administers the Uranium Mill Tailings Remedial Action (UMTRA) Project to clean up uranium mill tailings and other surface contamination at 24 abandoned uranium mill sites in 10 states. One of these abandoned mill sites was near the town of Gunnison, Colorado. Surface remediation was completed at the Gunnison site in December 1995. Remedial action resulted in the elimination of 4.3 acres of wetlands and mitigation of this loss is through the enhancement of 17.8 acres of riparian plant communities in six spring-fed areas on US Bureau of Land Management mitigation sites. A five-year monitoring program was then implemented to document the response of vegetation and wildlife to the exclusion of livestock. This report provides the results of the third year of the monitoring program.

  11. Increasing influence of air temperature on upper Colorado River streamflow

    This empirical study examines the influence of precipitation, temperature, and antecedent soil moisture on upper Colorado River basin (UCRB) water year streamflow over the past century. While cool season precipitation explains most of the variability in annual flows, temperature appears to be highly influential under certain conditions, with the role of antecedent fall soil moisture less clear. In both wet and dry years, when flow is substantially different than expected given precipitation, these factors can modulate the dominant precipitation influence on streamflow. Different combinations of temperature, precipitation, and soil moisture can result in flow deficits of similar magnitude, but recent droughts have been amplified by warmer temperatures that exacerbate the effects of relatively modest precipitation deficits. Since 1988, a marked increase in the frequency of warm years with lower flows than expected, given precipitation, suggests continued warming temperatures will be an increasingly important influence in reducing future UCRB water supplies.

  12. Paleomagnetism of clastic dikes along the Front Range, Colorado

    Dulin, S. A.; Elmore, R. D.

    2011-12-01

    Numerous clastic dikes occur within the Proterozoic basement along nearly 75km of the Front Range of Colorado. These dikes are composed predominately of well-rounded, non-metamorphosed quartz and are red in color due to the abundance of authigenic hematite. The Cambrian Sawatch sandstone is assumed by most studies to be the source of dike sediments due to its similar composition. Despite over a century of study, the origins, age, and emplacement mechanisms of these dikes remain enigmatic. A preliminary paleomagnetic study of the clastic dikes using standard demagnetization techniques indicates the presence of a complex multicomponent magnetization with at least three components. An easterly and moderately steep component residing in hematite was resolved from several dikes and corresponds to an early Cambrian pole position when compared to the apparent polar wander path of North America. An east-southeasterly and shallow magnetization, also residing in hematite, yields a pole of early Paleozoic age. The third component is northwesterly and steep down and is Mesozoic or Cenozoic in age. These results are similar to a previous paleomagnetic study (Kost, MS thesis, Univ. Colorado) in 1984 of different dikes which found poorly defined early and late Paleozoic, as well as Mesozoic-Cenozoic components. Many researchers suggest emplacement occurred during faulting that was associated with either the Ancestral Rockies uplift of the late Paleozoic or the Laramide orogeny of the late Mesozoic/early Cenozoic. The presence of magnetizations of Cambrian age, with subsequent younger remagnetizations, indicates that the emplacement of many of the dikes preceded both of these tectonic events.

    Butane hash oil (BHO), also known as "amber," "dab," "glass," "honey," "shatter," or "wax," is a potent marijuana concentrate, containing up to 90 % tetrahydrocannabinol (THC). BHO is easily manufactured using highly volatile butane as a solvent. Our objective was to characterize hydrocarbon burns associated with BHO manufacture in Colorado. This was a cross-sectional study utilizing the National Burn Repository to capture all hydrocarbon burns reported to the local burn center from January 1st, 2008, through August 31st, 2014. We abstracted demographic and clinical variables from medical records for patients admitted for hydrocarbon burns associated with butane hash oil extraction. Twenty-nine cases of BHO burns were admitted to the local burn center during the study period. Zero cases presented prior to medical liberalization, 19 (61.3 %) during medical liberalization (Oct 2009-Dec 2013), and 12 (38.7 %) in 2014 since legalization. The majority of cases were Caucasian (72.4 %) males (89.7 %). Median age was 26 (range 15-58). The median total-body-surface-area (TBSA) burn size was 10 % (TBSA range 1-90 %). Median length of hospital admission was 10 days. Six required intubation for airway protection (21 %). Nineteen required skin grafting, eight wound care only, one required surgical fracture repair, and one required surgical debridement. Hydrocarbon burns associated with hash oil production have increased since the liberalization of marijuana policy in Colorado. A combination of public health messaging, standardization of manufacturing processes, and worker safety regulations are needed to decrease the risks associated with BHO production. PMID:26289652

  14. The Colorado Plateau and its Role in the Laramide Orogeny

    Science.gov (United States)

    Bump, A. P.

    2001-12-01

    The Colorado Plateau is a relatively undeformed region bordered on the south and west by the highly extended Basin and Range province and on the north and east by the towering Laramide uplifts of the Rocky Mountains. Tectonically, the Plateau is a part of the Laramide orogen and contains basement-cored uplifts similar in style to those of the Rocky Mountains but with lower structural and topographic relief. Together, these observations have led some workers to hypothesize that the Plateau is anomalously strong and behaved as a rigid microplate during the Laramide orogeny. Evidence for a fundamental difference between the Plateau and the Rocky Mountains is largely circumstantial however, and is not supported by structural, topographic, geophysical or crustal assemblage data. The gradation in deformational intensity is better explained as the product of northeastward-increasing tectonic force, which is a predictable result of coupling between the North American crust and the flat, northeastward-subducting Farallon slab. Assuming that coupling-related stress and crustal strength are approximately constant, net force (and hence deformational intensity) grow with distance over which the coupling is active resulting in low tectonic force/minor deformation in the hinterland and high force/intense deformation in the foreland just before the subducting slab loses contact with the overriding plate. Minimal deformation of the Colorado Plateau is thus a logical result of its location in the hinterland of the Laramide orogen. Interpreted northeastward translation and clockwise rotation of the Plateau are consistent with a normal along-strike "bow and arrow" orogenic shortening profile and require no special explanation.

  15. On edge melting under the Colorado Plateau margin

    Asthenosphere beneath the relatively thin lithosphere of the Basin and Range province appears to be juxtaposed in step-like fashion against the Colorado Plateau's thick lithospheric keel. Primary to near-primary basalts are found above this edge, in the San Francisco-Morman Mountain volcanic fields, north central Arizona, western USA. We show that at least two distinct peridotite-dominated mantle end-members contributed to the origin of the basalts. One has paired Nd and Hf isotopic characteristics that cluster near the mantle array and trace element patterns as expected for melts generated in the asthenosphere, possibly in the presence of garnet. The second has isotopic compositions displaced above the ɛHf - ɛNd mantle array which, together with its particular trace element characteristics, indicate contributions from hydrogenous sediments and/or melt (carbonatite or silicate)-related metasomatism. Melt equilibration temperatures obtained from Si- and Mg-thermobarometry are mostly 1340-1425°C and account for the effects of water (assumed to be 2 wt.%) and estimated CO2 (variable). Melt equilibration depths cluster at the inferred location of the lithosphere-asthenosphere boundary at ˜70-75 km beneath the southwestern margin of the Colorado Plateau but scatter to somewhat greater values (˜100 km). Melt generation may have initiated in or below the garnet-spinel facies transition zone by edge-driven convection and continued as mantle and/or melts upwelled, assimilating and sometimes equilibrating with shallower contaminated mantle, until melts were finally extracted.

    This report explores the correlation between energy efficiency and the business success of home builders by examining a data set of builders and homes in the Colorado Springs, Colorado, market between 2006 and 2014. During this time, the Great Recession of 2007 to 2009 occurred, and new-home sales plummeted both nationally and in Colorado Springs. What is evident from an analysis of builders and homes in Colorado Springs is that builders who had Home Energy Rating System (HERS) ratings performed on some or all of their homes during the Recession remained in business during this challenging economic period. Many builders who did not have HERS ratings performed on their homes at that time went out of business or left the area. From the analysis presented in this report, it is evident that a correlation exists between energy efficiency and the business success of home builders, although the reasons for this correlation remain largely anecdotal and not yet clearly understood.

    Coe, B.A.; Zimmerman, J.

    1981-01-01

    The potential of four prospective geothermal development sites in Colorado was analyzed and hypothetical plans prepared for their development. Several broad areas were investigated for each site. The first area of investigation was the site itself: its geographic, population, economic, energy demand characteristics and the attitudes of its residents relative to geothermal development potential. Secondly, the resource potential was described, to the extent it was known, along with information concerning any exploration or development that has been conducted. The third item investigated was the process required for development. There are financial, institutional, environmental, technological and economic criteria for development that must be known in order to realistically gauge the possible development. Using that information, the next concern, the geothermal energy potential, was then addressed. Planned, proposed and potential development are all described, along with a possible schedule for that development. An assessment of the development opportunities and constraints are included. Technical methodologies are described in the Appendix. (MHR)

  20. Costs and Savings Associated With Community Water Fluoridation Programs in Colorado

    2005-11-01

    Full Text Available Introduction Local, state, and national health policy makers require information on the economic burden of oral disease and the cost-effectiveness of oral health programs to set policies and allocate resources. In this study, we estimate the cost savings associated with community water fluoridation programs (CWFPs in Colorado and potential cost savings if Colorado communities without fluoridation programs or naturally high fluoride levels were to implement CWFPs. Methods We developed an economic model to compare the costs associated with CWFPs with treatment savings achieved through averted tooth decay. Treatment savings included those associated with direct medical costs and indirect nonmedical costs (i.e., patient time spent on dental visit. We estimated program costs and treatment savings for each water system in Colorado in 2003 dollars. We obtained parameter estimates from published studies, national surveys, and other sources. We calculated net costs for Colorado water systems with existing CWFPs and potential net costs for systems without CWFPs. The analysis includes data for 172 public water systems in Colorado that serve populations of 1000 individuals or more. We used second-order Monte Carlo simulations to evaluate the inherent uncertainty of the model assumptions on the results and report the 95% credible range from the simulation model. Results We estimated that Colorado CWFPs were associated with annual savings of $148.9 million (credible range, $115.1 million to $187.2 million in 2003, or an average of $60.78 per person (credible range, $46.97 to $76.41. We estimated that Colorado would save an additional $46.6 million (credible range, $36.0 to $58.6 million annually if CWFPs were implemented in the 52 water systems without such programs and for which fluoridation is recommended. Conclusion Colorado realizes significant annual savings from CWFPs; additional savings and reductions in morbidity could be achieved if fluoridation

    2011-01-01

    A 2010 Colorado River symposium, held in Flagstaff, Arizona, involved 70 participants who engaged in intense debate about the origin and evolution of the Colorado River system. This symposium, built upon two previous decadal scientific meetings, focused on forging scientific consensus, where possible, while articulating continued controversies regarding the Cenozoic evolution of the Colorado River System and the landscapes of the Colorado Plateau-Rocky Mountain region that it drains. New developments involved hypotheses that Neogene mantle flow is driving plateau tilting and differential uplift and new and controversial hypotheses for the pre-6 Ma presence and evolution of ancestral rivers that may be important in the history and birth of the present Colorado River. There is a consensus that plateau tilt and uplift models must be tested with multidisciplinary studies involving differential incision studies and additional geochronology and thermochronology to determine the relative importance of tectonic and geomorphic forces that shape the spectacular landscapes of the Colorado Plateau, Arizona and region. In addition to the scientific goals, the meeting participants emphasized the iconic status of Grand Canyon for geosciences and the importance of good communication between the research community, the geoscience education/interpretation community, the public, and the media. Building on a century-long tradition, this region still provides a globally important natural laboratory for studies of the interactions of erosion and tectonism in shaping the landscape of elevated plateaus.

  9. A Dreissena Risk Assessment for the Colorado River Ecosystem

    Science.gov (United States)

    Kennedy, Theodore A.

    2007-01-01

    Executive Summary Nonnative zebra and quagga mussels (Dreissena polymorpha and Dreissena bugensis, respectively; see photo above) were accidentally introduced to the Great Lakes in the 1980s and subsequently spread to watersheds of the Eastern United States (Strayer and others, 1999). The introduction of Dreissena mussels has been economically costly and has had large and far-reaching ecological impacts on these systems. Quagga mussels were found in Lakes Mead and Havasu in January 2007. Given the likelihood that quagga mussels and, eventually, zebra mussels will be introduced to Lake Powell and the Colorado River at Lees Ferry, it is important to assess the risks that introduction of Dreissena mussels pose to the Colorado River ecosystem (here defined as the segment of river from just below Glen Canyon Dam to Diamond Creek; hereafter CRE). In this report, I assess three different types of risks associated with Dreissena and the CRE: (1) the risk that Dreissena will establish at high densities in the CRE, (2) the risk of ecological impacts should Dreissena establish at high densities in the CRE or in Lake Powell, and (3) the risk that Dreissena will be introduced to tributaries of the CRE. The risk of Dreissena establishing within the CRE is low, except for the Lees Ferry tailwater reach where the risk appears high. Dreissena are unlikely to establish at high densities within the CRE or its tributaries because of high suspended sediment, high ratios of suspended inorganic:organic material, and high water velocities, all of which interfere with the ability of Dreissena to effectively filter feed. The rapids of Grand Canyon may represent a large source of mortality to larval Dreissena, which would limit their ability to disperse and colonize downstream reaches of the CRE. In contrast, conditions within the Lees Ferry tailwater generally appear suitable for Dreissena establishment, with the exception of high average water velocity. If Dreissena establish within the

    Allen's big-eared bat (Idionycteris phyllotis) inhabits much of the southwestern USA, but has not been documented in Colorado. We recorded echolocation calls consistent with I. phyllotis near La Sal Creek, Montrose County, Colorado. Based on characteristics of echolocation calls and flight behavior, we conclude that the echolocation calls described here were emitted by I. phyllotis and that they represent the first documentation of this species in Colorado.

  11. Alteration and vein mineralization, Schwartzwalder uranium deposit, Front Range, Colorado

    Science.gov (United States)

    Wallace, Alan R.

    1983-01-01

    The Schwartzwalder uranium deposit, in the Front Range west of Denver, Colorado, is the largest vein-type uranium deposit in the United States. The deposit is situated in a steeply dipping fault system that cuts Proterozoic metamorphic rocks. The host rocks represent a submarine volcanic system with associated chert and iron- and sulfide-rich pelitic rocks. Where faulted, the more competent garnetiferous and quartzitic units behaved brittlely and created a deep, narrow conduit. The ores formed 70-72 m.y. ago beneath 3 km of Phanerozoic sedimentary rocks. Mineralization included two episodes of alteration and three stages of vein-mineralization. Early carbonate-sericite alteration pseudomorphically replaced mafic minerals, whereas the ensuing hematite-adularia episode replaced only the earlier alteration assemblage. Early vein mineralization produced a minor sulfide-adularia-carbonate assemblage. Later vein mineralization generated the uranium ores in two successive stages. Carbonates, sulfides, and adularia filled the remaining voids. Clastic dikes composed of fault gouge and, locally, ore were injected into new and existing fractures. Geologic and chemical evidence suggest that virtually all components of the deposit were derived from major hornblende gneiss units and related rocks. The initial fluids were evolved connate/metamorphic water that infiltrated and resided along the extensive fault zones. Complex fault movements in the frontal zone of the eastern Front Range caused the fluids to migrate to the most permeable segments of the fault zones. Heat was supplied by increased crustal heat flow related to igneous activity in the nearby Colorado mineral belt. Temperatures decreased from 225?C to 125?C during later mineralization, and the pressure episodically dropped from 1000 bars. The CO2 fugacity was initially near 100 bars, and uranium was carried as a dicarbonate complex. Sudden decreases in confining pressure during fault movement caused evolution of CO2

    of a population are difficult to detect locally. Contemporary issues in the conservation of native species demand regional and continental perspectives (Samson and Knopf 1982). Thus, management activities at specific sites are often viewed as short-sighted by planners and conservation critics. This paper illustrates how these contemporary theories can influence a local conservation perspective. That perspective is developed around historical processes that have led to cosmopolitism of the local avifauna on the Colorado Division of Wildlife's South Platte Wildlife Management Area (SPWMA) near Crook, Colorado.

  13. Colorado Yule Marble; building stone of the Lincoln Memorial

    Science.gov (United States)

    McGee, Elaine S.

    1999-01-01

    The Colorado Yule marble, quarried in Marble, Colo., is a very pure white marble, and it has been widely acclaimed for its quality and purity. This marble has been used for many prominent buildings; one of the most notable is the Lincoln Memorial in Washington, D.C., built nearly 80 years ago. Although most of the marble in the memorial appears to be in very good condition, some of the stones have developed pronounced surficial roughness and show a significant loss of carved details and rounded edges compared with adjacent stones. Because adjacent blocks of marble receive nearly identical exposure to weathering agents that cause deterioration of the marble, it seems very likely that this pronounced difference in durability of adjacent stones arises from some inherent characteristic of the marble. The Colorado Yule marble is a nearly pure calcite marble with minor inclusions of mica, quartz, and feldspar. Compositions of the calcite and the inclusion phases in the marble are typical for those phases. The calcite grains that compose the marble are irregularly shaped and range from 100 to 600 micrometers in diameter. The texture of the marble is even, with a slight preferred directional elongation that is visible when the marble is cut in certain directions. Physical tests of the marble show that its strength is comparable to that of other marbles typically used in buildings. Variations in the durability of the marble, like those seen at the Lincoln Memorial, are not related to variations in calcite composition or to the presence of inclusions in the marble. Most likely, the variations arise from differences in the calcite grain boundaries and the degree to which the grains interlock with one another. Weak grain boundaries that permit water or solutions to penetrate into the marble and dissolve the calcite grains at their edges cause the marble to disaggregate or ?sugar.? Subtle differences in texture that occur in the marble from various parts of the quarry probably

    The mountainous areas of Colorado are used for tourism and recreation, and they provide water storage and supply for municipalities, industries, and agriculture. Recent studies suggest that water supply and tourist industries such as skiing are at risk from climate change. In this study, a distributed-parameter watershed model, the Precipitation-Runoff Modeling System (PRMS), is used to identify the potential effects of future climate on hydrologic conditions for two Colorado basins, the East River at Almont and the Yampa River at Steamboat Springs, and at the subbasin scale for two ski areas within those basins. Climate-change input files for PRMS were generated by modifying daily PRMS precipitation and temperature inputs with mean monthly climate-change fields of precipitation and temperature derived from five general circulation model (GCM) simulations using one current and three future carbon emission scenarios. All GCM simulations of mean daily minimum and maximum air temperature for the East and Yampa River basins indicate a relatively steady increase of up to several degrees Celsius from baseline conditions by 2094. GCM simulations of precipitation in the two basins indicate little change or trend in precipitation, but there is a large range associated with these projections. PRMS projections of basin mean daily streamflow vary by scenario but indicate a central tendency toward slight decreases, with a large range associated with these projections. Decreases in water content or changes in the spatial extent of snowpack in the East and Yampa River basins are important because of potential adverse effects on water supply and recreational activities. PRMS projections of each future scenario indicate a central tendency for decreases in basin mean snow-covered area and snowpack water equivalent, with the range in the projected decreases increasing with time. However, when examined on a monthly basis, the projected decreases are most dramatic during fall and

  19. Seismicity of the Paradox Basin and the Colorado Plateau interior

    International Nuclear Information System (INIS)

    National Waste Terminal Storage Program site qualification criteria require that a nuclear waste repository be located so that ground motion associated with the maximum credible and maximum probable earthquakes or other earthquake-associated effects will not have an unacceptable adverse impact on system performance. To determine whether a potential repository site located in the Paradox salt formation in the Paradox Basin of southeastern Utah satisfies these criteria, seismological studies were undertaken by Woodward-Clyde Consultants (WCC) in March 1978. These studies included: (1) analysis of historical seismicity; (2) analysis of contemporary seismicity and tectonics of both the Paradox Basin and surrounding Colorado Plateau, including an extensive program of microearthquake monitoring; (3) evaluation of the Paradox Basin crustal structure; (4) evaluation of mining-induced seismicity; and (5) characterization of design-related earthquake-induced ground motions pertinent to a potential repository site through studies of attentation and subsurface ground motions. A detailed discussion of the results of the seismological studies performed through December 1980 is contained in WCC (1982). The purpose of this topical report is to update and summarize the studies on the local, regional, and mining-induced seismicity conducted through December 1982. The limitations of any interpretations are also discussed and additional information that remains to be acquired is identified. 56 references, 45 figures, 4 tables

    The Pine Mountain quadrangle is one of eighteen 7 1/2-minute quadrangles covering the principal carnotite-producing area of southwestern Colorado. The geology of these quadrangles was mapped by the U.S. Geological Survey for the Atomic Energy Commission as part of a comprehensive study of carnotite deposits. The rocks exposed in the eighteen quadrangles consist of crystalline rocks of pre-Cambrian age and sedimentary rocks that range in age from Paleozoic to Quaternary. Over mush of the area the sedimentary rocks are flat lying, but in places the rocks are disrupted by high-angle faults, and northwest-trending folds. Conspicuous among the folds are large anticlines having cores of intrusive salt and gypsum. Most of the carnotite deposits are confines to the Salt Wash sandstone member of the Jurassic Morrison formation. Within this sandstone, most of the deposits are spottily distributed through an arcuate zone known as the "Uravan Mineral Belt". Individual deposits range in sizer from irregular masses containing only a few ton of ore to large, tabular masses containing many thousands of tons. The ore consists largely of sandstone selectively impregnated and in part replaced by uranium and vanadium minerals. Most of the deposits appear to be related to certain sedimentary structures in sandstones of favorable composition.

    With the help of faculty from all eight colleges, twenty-seven departments, and numerous other entities on and off the Colorado State University campus, this education and outreach initiative is based on the premises that climate change is everybody's business and that everyone has something to offer in meeting its challenges. Beginning in 2007, CC@CSU has organized some 120 talks to audiences totaling some 6,000, helping inform the student body and community and catalyzing relationships among faculty and researchers across campus. It has offered communication coaching to scientists (and others) who want to translate their expertise for the public. And it has developed a multidisciplinary website (http://changingclimates.colostate.edu) with over 450 annotated entries, all college-level content, primer-level clarity, on topics that include climate science and ecology, economics and emotions, ethics and policy, communication and activism, paleoclimate and human history, and much more. This presentation will address the basic questions of why, who, how, what, for whom, and so what, concluding with some of the key lessons learned about communicating across disciplinary boundaries on this important subject.

  11. Analysis of Renewable Energy Deployment in Colorado by 2030

    This paper reports that, currently, most utilities in the state of Colorado are subject to the 20% renewable portfolio standard (RPS) passed by voters in 2004 and expanded by the state legislature in 2007. However, because of bonuses and exemptions written into the law, the true required renewable energy penetration is only 12.3%, making the law less then adequate for addressing climate change. The study aims to assess the real renewable energy and carbon impacts of the current RPS and investigates the benefits of increasing the RPS to true 20% and 30% values. A user input-driven predictive Excel model was developed to find the proper technology spread, electrical outputs, and carbon reduction for each RPS. It was found that while all the RPS variants are technically feasible based on available renewable resources, only the 30% RPS meets the carbon reductions that are thought necessary to avoid the worst impacts of climate change. The report then comments on the results and what RPS percentage will be the most acceptable avenue.

  12. An ecosystem approach to combat desertification on the Colorado Plateau.

    2004-12-01

    Desertification of shrub and grassland into pinyon-juniper woodland is occurring over much of the Colorado Plateau in the southwestern United States. As trees invade, they out-compete shrubs and grasses, increasing erosion rates and reducing infiltration of moisture into the soil. This has caused habitat problems for wildlife, and reduced forage for livestock. These impacts also affect the human communities that rely on ranching and tourism related to hunting. Past land use and management practices including heavy livestock grazing, fire suppression and introduction of exotic annual plants are believed to have led to current conditions. The Montrose office of the Bureau of Land Management has implemented an ecosystem-based program to reverse the desertification process on public land. The program is centered on detailed landscape objectives describing the desired vegetation mosaic on 360,000 ha of public land. The objectives outline proportions of plant seral stages and arrays of patch sizes for each planning unit. These objectives are based on priority management issues and the need to replicate a natural vegetation mosaic. Where the existing mosaic does not meet objectives, mechanical vegetation treatments and prescribed fire are used to create early and mid-seral patches on the ground. This restored vegetation pattern and type should be sustained over time through a natural fire regime and improved livestock management. Because many uncertainties exist, an adaptive management process is being used that allows mosaic objectives to be changed or processes modified where monitoring or scientific research indicate a need.

    The U.S. Bureau of Land Management leases Federal lands and minerals for coal mining near Durango, Colorado. This report addresses the hydrologic suitability of those lands for coal leasing; the report describes the general hydrology of the Durango area and, more specifically, the hydrology of the Stollsteimer Creek study area 32 miles east of the Durango and the Hay Gulch study area, 12 miles southwest of Durango. The most productive aquifers in the Durango study area are Quaternary alluvium and the tertiary Animas Formation. Water wells completed in alluvium typically yield 5 to 20 gallons/min; wells completed is the Animas Formation yield as much as 50 gallons/min. Water quality in these aquifers is variable, but it generally is suitable for domestic use. The coal-bearing Cretaceous Fruitland and Menefee Formations are mined by surface methods at the Chimney Rock Mine in the Stollsteimer Creek study area and by underground methods at the National King Coal Mine in the Hay Gulch study area. Effects of surface mining in the Stollsteimer Creek area are: (1) Dewatering of an alluvial aquifer; and (2) Local degradation of alluvium water quality by spoil-pile effluent. Effects of underground mining in the Hay Gulch area are: (1) Introduction of water with greater dissolved-solids concentrations into the upper Hay Gulch alluvium from mine runoff; (2) Subsidence fracturing which could dewater streams and the alluvial aquifer.

    A color vegetation map at the scale of 1:12,000 of the area surrounding the Rocky Flats, Rockwell International Plant near Boulder, Colorado, provides a permanent record of baseline data which can be used to monitor changes in both vegetation and environment and thus to contribute to future land management and land-use policies. Sixteen mapping units based on species composition were identified, and characterized by two 10-m/sup 2/ vegetation stands each. These were grouped into prairie, pasture, and valley side on the basis of their species composition. Both the mapping units and these major groups were later confirmed by agglomerative clustering analysis of the 32 vegetation stands on the basis of species composition. A modified Bray and Curtis ordination was used to determine the environmental factor complexes controlling the distribution of vegetation at Rocky flats. Recommendations are made for future policies of environmental management and predictions of the response to environmental change of the present vegetation at the Rocky Flats site.

    The Uranium Mill Tailings Remedial Action (UMTRA) Project is administered by the U.S. Department of Energy (DOE); its purpose is to cleanup uranium mill tailings and other contaminated material at 24 UMTRA Project sites in 10 states. This report summarizes the wildlife mitigation and monitoring program under way at the Gunnison UMTRA Project, Gunnison, Colorado. Remedial action at the Gunnison site was completed in December 1995 and is described in detail in the Gunnison completion report. The impacts of this activity were analyzed in the Gunnison environmental assessment (EA). These impacts included two important game species: the pronghorn antelope (Antilocapra americans) and sage grouse (Wentrocerus urophasianus). Haul truck traffic was predicted to limit antelope access to water sources north of the Tenderfoot Mountain haul road and that truck traffic along this and other haul roads could result in antelope road kills. Clearing land at the disposal cell, haul road and borrow site activities, and the associated human activities also were predicted to negatively impact (directly and indirectly) sage grouse breeding, nesting, loafing, and wintering habitat. As a result, an extensive mitigation and monitoring plan began in 1992. Most of the monitoring studies are complete and the results of these studies, written by different authors, appear in numerous reports. This report will: (1) Analyze existing impacts and compare them to predicted impacts. (2) Summarize mitigation measures. (3) Summarize all existing monitoring data in one report. (4) Analyze the effectiveness of the mitigation measures.

    Full Text Available Esta investigación se llevó a cabo para determinar la distribución espacial de la densidad (captura por unidad de área - CPUA y de la estructura de tallas de Eucinostomus argenteus y su relación con las variables ambientales en la zona norte del Caribe colombiano. Los datos fueron se tomaron durante un crucero de investigación realizado en la época seca (Febrero de 2006 entre Puerto Estrella ( La Guajira y Santa Marta (Magdalena. Las muestras biológicas se colectaron con una red de arrastre (en estratos de profundidad This research was carried out to determine the spatial distribution of density (catch per unit area - CPUA and size structure of Eucinostomus argenteus and their relationship with environmental variables in the north zone of the Colombian Caribbean sea. The data comes from a survey of fisheries research during the dry season (February of 2006 between Puerto Estrella ( La Guajira and Santa Marta ( Magdalena . Biological samples were taken with a bottom trawl net (< 50 m and 50- 100 m stratum of depth following a systematic design survey. The mature fishes with higher sizes were mainly located in the sector between Manaure and Punta Gallinas, where the continental shelf is very wide and the local oceanography is modulated by the seasonal upwelling. The juvenile fishes were found toward the south of the study area between Boca Camarones and the Rio Buritaca, close to the coast. In this sector the continental shelf is very narrow with high biological productivity for the presence of rivers, mangroves and sea grasses, which serve as feeding grounds and nursery habitat for E. argenteus. In general, our results suggest that environmental conditions were important determinants of spatial distribution of abundance and sizes of E. argenteus in the north zone of the Colombian Caribbean Sea, with temperature and depth as variables that better predict the spatial distribution of this specie.

    Full Text Available OBJECTIVE: To identify country-level correlates of geographical variations in cervical cancer (CC mortality in Latin America and the Caribbean (LAC. MATERIALS AND METHODS: CC mortality rates for LAC countries (n=26 were examined in relation to country-specific socio-economic indicators (n=58 and Human Papilloma Virus (HPV prevalence using linear regression models. RESULTS: High mortality at ages OBJETIVO: Identificar variables a nivel de país que expliquen las variaciones geográficas en la mortalidad por cáncer cervicouterino (CaCu en América Latina y el Caribe (AL. MATERIALES Y MÉTODOS: Se examinaron las tasas de mortalidad por CaCu de cada país (n=26 mediante modelos de regresión lineal en relación con indicadores socioeconómicos (n=58 y prevalencia del virus del papiloma humano (VPH. RESULTADOS: Alta mortalidad en menores de cinco años, bajo gasto total en salud per-cápita y baja proporción de población con acceso a saneamiento básico son los mejores predictores de mortalidad por CaCu (R² =77%. En los países (n=10 con estimaciones de prevalencia de VPH, estos indicadores socioeconómicos y la prevalencia de VPH de alto riesgo explicaron el 98% de la variabilidad de CaCu en AL. CONCLUSIÓN: Las mejoras en el nivel socioeconómico en AL están asociadas con reducciones en la mortalidad por CaCu, a pesar de la ausencia de programas organizados de tamizaje e inmunización contra VPH.
