Relaciones entre el inicio y el término de la estación lluviosa en Centroamérica y los océanos Pacífico y Atlántico tropical/ Relationships between the Start and End Date of the rainy season in Central America and the Tropical Atlantic and Pacific Oceans

Alfaro, Eric; Cid, Luis; Enfield, David
1998-01-01

Resumen en español En los últimos años diversos estudios han mostrado que las anomalías en los campos de temperaturas de los océanos Pacífico y Atlántico Tropical están relacionadas con variaciones, tanto en la intensidad como en la duración de la estación lluviosa sobre Centroamérica. En este trabajo se usaron, como variables independientes, distintos índices oceanográficos y atmosféricos, principalmente de las distribuciones de la temperatura superficial del mar (TSM) en los (mas) océanos Pacífico y Atlántico Tropical, para explicar las variaciones en las fechas de inicio (IELL) y término (TELL) de estación lluviosa sobre la región centroamericana. El índice del Atlántico Norte (ATN) y los índices IOS-Niño3 mostraron las mayores correlaciones con el IELL y el TELL, respectivamente Resumen en inglés In recent years, several studies had shown that anomalies in the sea surface temperature of the Tropical Atlantic and Pacific Oceans are related to variations in the intensity and timing of the rainy season in Central America. In order to study anomalous behavior of the rainy season over Central America, Tropical Atlantic and Pacific Oceans indices are used to produce correlation series with the starting and ending date (IELL and TELL) of the rainy season. The North Atlantic (ATN) and SOI-Niño3 indices, shown the main correlations with the IELL and the TELL respectively

Análisis y edad de la sección calcárea de la Formación Las Chilcas (Chile) y sus implicancias para la correlación con unidades de Argentina/ Analysis and age of the calcareous section of Las Chilcas Formation (Chile) and its implications for correlation with Argentine units

Tunik, Maísa A.; Álvarez, Patricia, P.
2008-09-01

Resumen en español La Formación Las Chilcas es una unidad volcaniclástica que posee depósitos calcáreos en la vertiente oriental de la Cordillera de la Costa y en la depresión central de Chile. Diferentes reconstrucciones paleogeográficas la han relacionado con las Formaciones Algarrobo y Quiriquina producto de la ingresión marina maastrichtiana del Pacífico y alternativamente con la ingresión marina maastrichtiana procedente del Atlántico. Esta impresión ha sido registrada en el (mas) sector andino con los depósitos de la Formación Saldeño, unos kilómetros al este del Paso de Piúquenes cerca de los 33°30´ latitud sur. Estudios paleoambientales y paleontológicos indican que los sedimentos de la Formación Las Chilcas se desarrollaron en un ambiente marino somero con influencias mareales durante el Cretácico temprano. Los resultados de este trabajo permiten desvincular definitivamente a estos sedimentos calcáreos de los sedimentos de la Formación Saldeño y de los de la Formación Quiriquina y sus equivalentes temporales. De esta manera, queda descartada una posible comunicación entre los océanos Atlántico y Pacífico a la latitud de 33°30´ latitud sur durante el Cretácico tardío. Estos datos muestran claramente un levantamiento de los Andes para el Cretácico tardío a estas latitudes. Resumen en inglés The calcareous beds of Las Chilcas Formation outcrop along the eastern flank of the Coastal Range and in the central valley of Chile. Different paleogeographic reconstructions have related this unit to the Late Cretaceous Algarrobo and Quiriquina Formations as part of the Maastrichtian marine ingression from the Pacific or alternatively with the Atlantic ingression. It has also been compared with calcareous rocks located a few kilometers east of the Piúquenes Pass, known (mas) in Argentina as Saldeño Formation. Paleoenvironmental and paleontological analyses carried out in Las Chilcas Formation showed that it was developed in a tidal carbonatic system during the Early Cretaceous. These results definitively desvinculate the sediments from Las Chilcas Formation from the Quiriquina Formation or other Maastrichtian deposits from the Atlantic and Pacific ingressions. Based on the present data, it is ruled out a seaway between the Pacific and the Atlantic oceans at the 33°30´ south latitude during the Late Cretaceous. These new data clearly indicate that a tectonic uplift of the Andes separates both ingressions during the Late Cretaceous at these latitudes.

Facies del subfondo del canal Beagle, Tierra del Fuego/ Sub-bottom facies of the Beagle Channel, Tierra del Fuego

Bujalesky, Gustavo; Aliotta, Salvador; Isla, Federico
2004-03-01

Resumen en español El canal Beagle conecta los océanos Pacífico y Atlántico en el extremo meridional de Sudamérica y se ubica en el ambiente subantártico. Conforma una cuenca de unos 300 m de profundidad máxima y está separada del océano Atlántico por un umbral de 30 m de profundidad. El canal es un valle tectónico que fue completamente cubierto por el hielo glacial durante la última glaciación. Posteriormente, el canal fue ocupado por un lago glacial desde los 12.000 a los 8.00 (mas) 0 años A.P., cuando fue invadido por el mar que alcanzó un nivel máximo entre los 6.000 y 5.000 años A.P. Con el objetivo de analizar las facies sedimentarias superficiales y del subfondo del canal se realizó un relevamiento geofísico con sonar de barrido lateral y un perfilador de 3,5 kHz. Sobre un basamento constituido por rocas metamórficas del Mesozoico, se identificaron depósitos de till y secuencias granodecrecientes que representan distintos estadios del retroceso glaciar, evidenciando hacia la sección superior facies lacustres y por encima depósitos de la transgresión marina del Holoceno. Además, se han identificado paleocauces y secuencias fluviales cubiertas por sedimentos marinos transgresivos. Resumen en inglés The Beagle Channel connects the Pacific and Atlantic oceans in the southernmost part of South America, and has a subantarctic environment. It is a deep basin (300 m depth) separated from the Atlantic Ocean by a shallow sill (30 m depth). The Beagle Channel is a tectonic valley that was completely covered by ice during the Last Glaciation. Later, it was occupied by a glacial lake from 12,000 to 8,000 years B.P. and then flooded by the sea, reaching a maximum sea level betw (mas) een 6,000 and 5,000 years B.P. A geophysical survey (side scan sonar and 3.5 kHz profiler) was carried out in the channel to analyze the sea-bed and sub-bottom sedimentary facies. Metamorphic Mesozoic basement rocks are overlain by glacial deposits (till) and fining upwards sequences. These sequences represent different stages of the glacial retreat, showing in their upper parts proglacial lacustrine facies. Holocene marine deposits overlie the glacigenic deposits. Palaeovalleys and submerged fluvial sequences transgressed by marine deposits were also observed.

Pensar una Patagonia con dos océanos: el proyecto de desarrollo de Ezequiel Ramos Mexía/ Thinking Patagonia with two oceans: the development project of Ezequiel Ramos Mexía

Bandieri, Susana
2009-12-01

Resumen en español Las posibilidades productivas de la región, con escasas condiciones para las prácticas agrícolas pero adecuadas para la ganadería extensiva, predominantemente lanar, hicieron finalmente que la inserción patagónica se pensara dentro del mismo modelo de crecimiento "hacia afuera" delineado para el conjunto nacional sobre fines del siglo XIX y comienzos de XX. El único intento superador producido en ese período, aunque frustrado, lo constituyó el proyecto de desarro (mas) llo patagónico elaborado por el Ministro de Obras Públicas del presidente Figueroa Alcorta, Ezequiel Ramos Mexía, concretado en la "Ley de Fomento de los Territorios Nacionales" nº 5.559 del año 1908. El ministro, hijo y nieto de estancieros bonaerenses, tenía una concepción amplia en materia de desarrollo económico y, en ese sentido, la Patagonia aparecía como el territorio adecuado para generar algunos cambios en un país que por entonces sólo se pensaba en términos agrícolas y pastoriles. Resumen en inglés Productive possibilities in Patagonia region, from the point of view of natural resources, were based up on the cattle range (mainly sheep) as well as a lightly agriculture. Because of that, economic growing was planned as "growing for outside", as it was carried out and considered for the national development in the end of 19th century and also the beginning of the 20th one. Nevertheless, there was an exception: that was the frustrated project of patagonian development t (mas) hought and written by Ezequiel Ramos Mexía, Ministry of Public Works of President Figueroa Alcorta. It was set up in the promotion law of National Territories N° 5.559 of 1908. The ministry, son and grandson of great land owners of the pampean region, province of Buenos Aires, had a wide angle of thinking about economic development affairs. In this respect, Patagonia looks to him as a suitable territory to improve out a process of development which can go further than a country based on the simple production of agrarian commodities, as it was in general, the policy followed in those times.

Foraminíferos de la Formación Irigoyen, Neogeno, Tierra del Fuego, Argentina: su significado paleobiogeográfico/ Foraminifers from the Irigoyen Formation, Neogene, Tierra del Fuego, Argentina: their paleobiogeographic significance

Malumián, Norberto; Scarpa, Romina
2005-06-01

Resumen en español En la Formación Irigoyen (Mioceno superior-Plioceno, cuenca transtensiva del río Irigoyen, costa atlántica de Tierra del Fuego) se reconocen dos agrupamientos de foraminíferos bentónicos de aguas someras de fuerte carácter austral. El agrupamiento inferior, dominado por Angulogerina angulosa fueguina (Malumián), es en general similar a los foraminíferos de la Formación Carmen Silva, contiene " Trochoelphidiella " sp., previamente descrita para el Oligo-Mioceno de (mas) la Antártida. El agrupamiento superior está dominado por Nonion hancocki Cushman y McCulloch, una especie previamente conocida sólo en las actuales costas peruanas, y contiene frecuente Cribrorotalia meridionalis (Cushman y Kellett), especie que en la actualidad se distribuye abundantemente desde el canal de Beagle y por la costa pacífica hasta el Perú; ambas especies le otorgan un carácter pacífico al agrupamiento. Este carácter pacífico, junto con coincidentes características morfoestructurales, sugieren una directa conexión entre los océanos Atlántico y Pacífico por medio de un paleocanal plioceno, aquí denominado "paleocanal de Hoces" similar al canal de Beagle. El paleocanal de Hoces ocupó el lugar de las actuales depresiones vinculadas a la falla Magallanes-Fagnano, desde el seno del Almirantazgo, por el lago Fagnano y hasta la cuenca trastensiva de Irigoyen. Resumen en inglés Two shallow-water assemblages of benthic foraminifers of strong austral character are recognized in the Irigoyen Formation (Upper Miocene-Pliocene, Río Irigoyen transtensive Basin, Atlantic coast of the Tierra del Fuego Island). The lower assemblage, dominated by Angulogerina angulosa fueguina (Malumián), is in general similar to the assemblage known from the Carmen Silva Formation; it contains " Trochoelphidiella " sp., previously described from the Antarctic Oligo-Mio (mas) cene. The upper assemblage is dominated by Nonion hancocki Cushman and McCulloch, a species previously known only from the modern Peruvian coast, and contains frequent Cribrorotalia meridionalis (Cushman and Kellett), which is abundant from the Beagle channel up to the Peruvian coast as a living species, giving both species a Pacific aspect to the assemblage. This Pacific aspect, together with coincident morphoestructural features, suggest a direct shallow connection between the Atlantic and Pacific Oceans by means of a Pliocene paleochannel, here called the "paleocanal de Hoces", similar to the modern Beagle channel. The Hoces paleochannel was running on the areas occupied now by depressions such as the Seno Almirantazgo, the Fagnano Lake and the Irigoyen Basin, related to the Magallanes-Fagnano fault.

La época del imperialismo y sus implicaciones en la salud pública/ Imperialist times and its implications for public health

Estrada M, John H
2008-07-01

Resumen en español Este artículo estudia el denominado gran siglo XIX o largo siglo XIX, que comprende todo este siglo más las décadas que antecedieron y acompañaron a la primera guerra mundial y que se corresponde con la consolidación del imperialismo. Desde la perspectiva de la salud pública, es importante por haberse producido la transición de la higiene a la salud pública y que ya en 1880 caracteriza el advenimiento de la teoría bacteriológica y su influencia en las medidas de (mas) sanidad estatal imperantes. La medicina antes de 1900 se caracterizaba por: 1) predominio de lo militar y de lo imperial; 2) principios de prevención importados y concentrados en prácticas sanitarias; 3) la medicina colonial no estaba separada de la medicina imperial; 4) interés en las colonias como fuerzas productivas o de inestabilidad política; 5) el interés pasó de las medidas de sanidad general a la búsqueda de agentes específicos para las enfermedades y a medidas para su control; y 6) la medicina tropical se vuelve una especialidad de posgrado. El fenómeno del imperialismo norteamericano comparte las principales características con el imperialismo europeo, pero se diferencia en las medidas sanitarias, pues los americanos temían la introducción de enfermedades prevalentes en los trópicos, ya fuera por México, el Atlántico o el Pacífico, para lo cual diseñaron e implantaron rigurosas medidas de inspección y control en los países donde tenían intereses comerciales y en los puertos de embarque de pasajeros y mercancías hacia su territorio. El surgimiento de la medicina estatal en nuestra subregión es una consecuencia de la instauración de modos de producción capitalista, ya que las relaciones sociales y económicas de los individuos con el Estado fueron duramente afectadas y transformadas por los procesos de incipiente industrialización y consolidación de dicho modelo de producción. Ello implicó la consolidación de un cuerpo burocrático y un aumento de la intervención en la vida de los ciudadanos por la vía de las políticas sociales. En Colombia, la introducción de las prácticas de higiene y luego de la bacteriología tienen un discurrir particular, lo cual se pone de relieve a lo largo del siglo XIX, cuando la burguesía en el poder respondió más a fenómenos episódicos, como las epidemias de viruela, cólera o fiebre amarilla que recorrieron con mayor o menor severidad el país, desde los litorales Atlántico y Pacífico hasta el interior, con el riesgo de diezmar las poblaciones obreras y afectar el incipiente intercambio comercial del país. Resumen en inglés This articles studies the period called by historians as the Big or Long XIX century. Besides the XIX century by itself, it encompasses the decades that preceded it and the decades of the First World War. All of them belong to the consolidation of imperialism. From the perspective of public health, the Big XIX Century is important because of the transition from hygiene to public health, and the beginning of the bacteriologic theory in 1880, influencing sanitary control me (mas) asures of the State. Before 1900, medicine was characterized by: 1) predominance of military and of imperial approaches, 2) prevention principles were imported and concentrated in sanitary practices; 3) colonial medicine was not separated from imperial medicine; 4) interest focused on colonies as productive forces or as sources of political instability; 5) the main concern went from general sanitary measurements to the search for specific disease agents and their control measurements; and 6) tropical medicine becomes a postgraduate specialty. North- American imperialism shares the main characteristics of European imperialism, but the difference was centered in the sanitary measurements because Americans feared the introduction of prevalent diseases from the tropics to their territory either through Mexico or through the ports in the Atlantic or the Pacific oceans. In order to avoid this, Americans designed and implemented rigorous inspection and control measurements in the countries where they had commercial interests and in the ports where passengers and merchandise were headed to the United States. The appearance of state medicine in Latin American is a logical consequence of the implementation of the capitalistic mode of production, provided social and economic relationships between the people and the State were hardly affected and transformed by the incipient industrialization and consolidation of such a production model. This implied the consolidation of a bureaucratic mass and an increased intervention in everyday lives of the citizens via the social policies. In Colombia, the beginning of hygiene practices and, later on, of bacteriology developed in very distinctive ways. This can be observed along the XIX century, a period in which the bourgeoisie responded mainly to episodic events such as smallpox, cholera or yellow fever epidemics, which affected the whole country with different degrees of severity from both Atlantic and Pacific coasts towards the inner part of the country, threatening to reduce the population of workers and affecting the incipient commercial exchange of the country.

Durante la temporada estival 2004- (mas) 2005, se encontró un predominio de grupos con alto grado de endemismo en el Océano Austral, representados por Myctophiidae, Nototheniidae, Channichthyidae y Bathydraconidae, que en conjunto constituyeron más del 62% de las especies ícticas del sector, frente a un 38% de especies cosmopolitas. El aporte por familia mostró un predominio de Myctophiidae, Channichthyidae, Gempylidae y Nototheniidae, con el 98% de las capturas, frente al 2% correspondiente a peces cosmopolitas Resumen en inglés The catch composition of Channichthyidae family in mesopelagic water over the slope of South Georgia Island, Antarctica, is analized. Three species from this family were detected in the sector, represent 12% of total ichthyic diversity and 37% of total ichthyic cathes. Champsocephalus gunnari and Chaenocephalus aceratus made up 95% of Channichthyidae cathes, and Pseudochaenichthys georgianus made up the other 5%. In the summer of 2004-2005, groups that are highly endemic (mas) to the southern oceans predominated. These were Myctophiidae, Nototheniidae, Channichthyidae and Bathydraconidae. Together these families represented more than 62% of the ichthyic diversity in the sector, the 38% were cosmopolitan fish. The contribution of each family showed that Myctophiidae, Channichthyidae, Gempylidae and Nototheniidae, predominated, making up 98% of the ichthyic catches, with the remaining 2% being cosmopolitan fish

Análisis de cadenas de Markov y series de Fourier en una secuencia hemipelágica del Jurásico superior de la Península Antártica

Kietzmann, Diego A.; Cuitiño, José I.; Medina, Rubén A.; Scaso, Roberto A.
2009-07-01

Resumen en español La Formación Ameghino (Kimmeridgiano-Berriasiano), Cuenca Larsen, Península Antártica, está compuesta por una asociación de microfacies de pelitas con radiolarios (P1), pelitas negras (P2), pelitas bioturbadas y peloidales (P3), tobas (T) y areniscas (A) excelentemente preservadas. Este conjunto de microfacies revela sedimentación pelágica/ hemipelágica en un ambiente deficiente en oxígeno, periódicamente interrumpida por caídas de cenizas del arco volcánico a (mas) ntártico. Análisis basados en cadenas de Markov indican la recurrencia de las microfacies y sus relaciones cíclicas. Se interpreta que la alternancia de pelitas con radiolarios y pelitas negras (P1-P2) responde a variaciones en la productividad/dilución, mientras que las microfacies de tobas y areniscas corresponden a depósitos de evento que modificaron las condiciones ambientales y diagenéticas evitando la disolución de los esqueletos de radiolarios en la masa de agua y en el fondo, y generando de este modo una memoria markoviana con ciclos T-P1-P2. Por otra parte, el análisis por transformadas de Fourier indica para los ciclos P1-P2 una duración del orden de 1000 años, en el rango de variaciones sub-Milankovitch. Resumen en inglés The Upper Jurassic strata of the Larsen Basin, in the northeastern tip of the Antarctic Peninsula (Fig. 1), consist of thin, well-bedded, radiolarian-rich shales, fallout tuffs and volcaniclastic sandstones, grouped in a stratigraphic unit known as Ameghino Formation (or Nordenskjöld Formation for British authors - see Whitham and Doyle, 1989). The Ameghino Formation succession records a fine-grained and high-rate continuous suspensive sedimentation in a quiet hemipelagi (mas) c environment, with little reworking at the bottom. A 1.3 m-thick representative section for the Upper Member of the Ameghino Formation was sampled bed by bed and studied under petrographic microscopy for microfacies determination. Cyclicity was defined by means of Markov chain analysis and Fourier series (Blackman- Tukey and wavelet methods). Microfacies: The succession is composed of a microfacies association of radiolarianrich shales (P1), black shales (P2), bioturbated and peloidal shales (P3), tuffs (T) and sandstones (A) superbly preserved (Figs. 2 and 3). Sedimentation took place in an oxygen-depleted environment, periodically interrupted by rapid, event-sedimentation mostly caused by large explosive eruptions at the volcanic arc of the Antarctic Peninsula. The P1 and P2 microfacies are interpreted as the result of the deposition from pelagic suspensions during cycles of varying biological productivity or terrigenous dilution. The microfacies P3 represents similar conditions of sedimentation but higher oxygenation levels at the bottoms. On the other hand, microfacies T and A correspond to fallout deposits and distal turbiditic flows respectively. Microfacies T is associated with siliciclastic explosive volcanic eruptions and microfacies A with reworking of primary pyroclastic deposits. Markov chain and Fourier series analysis: Markov chain analysis reveal cyclic relations between some microfacies with single step transition dependence (Figs. 4 and 5). Transition diagram shows statistically significant transitions from microfacies T and A to P1, between P1 and P2, and also a cycle T-P1-P2 (Fig. 6). Spectra from the Fourier series analysis on 37 pairs P1-P2 (Fig. 7 a) indicate a periodicity of 1140 years (Blackman-Tukey method, 95% confidence, Fig. 7b), and periodicities of 740 and 1160 years (wavelet method, Fig. 7c). Ages were derived from sedimentation rates calculated by Scasso (2001) for the Longing Member due to poor age determinations in the upper Member. A periodicity of about 1000 years may be associated with the Hallstatt cycle of solar activity that influence the intensity of solar radiation reaching the Earth and cause surface temperature variations within the sub-Milankovitch frequency band. A similar frequency was calculated by Scasso (2001) for large volcanic eruptions from the tuff record in the Longing Member. Therefore, P1- P2 transitions are associated to climatic cycles that influence productivity at the surface of the oceans. The accumulation of microfacies T and A are related to events of siliciclastic sedimentation that modified environmental and early-diagenetic conditions avoiding dissolution of radiolarian skeletons in the water body and at the bottom and caused the T and A transitions to P1. P2-T transition might indicate that P2 environmental conditions lasted longer than P1 conditions in spite of the similar thickness observed for both microfacies.
