    The effects of 12500 E calcium heparin given once daily were contrasted with those seen under daily treatment with 12500 E of a semisynthetic heparin analogue (SSHA) and evaluated using iodine-125-labelled fibrinogen. The study included 80 patients, who were randomly assigned to the two treatment groups on a 1:1 basis. The findings revealed here led to the conclusion that both drugs, administered once daily by the subcutaneous route, were effective in preventing the occurrence of thrombosis during radiation treatment of gynaecological tumours.

    The future of atomic energy in Bulgaria is discussed in terms of the challenge to make correct political and economical decisions. The building of a second nuclear power plant at Belene should be considered taking into account the time needed for project realisation and the adherence to standards. The political aspects are connected closely to the financial crediting and to marketing research for electricity export. It is stressed that the development of atomic energy is closely related to the national stability and economical independence.

    The Geological Survey is conducting a programe of research in laboratory analysis of tritium and in several field projects designed to test the value of tritium in hydrologie research. Laboratory studies have been undertaken to improve the gas-phase counting technique and to develop a simple instrumentation adapted to programme requirements of long-range hydrologie research. Investigation of various gas-counting mixtures indicates that hydrogen-ether and hydrogen-ethylene mixtures are superior. Electrolytic enrichment has been investigated with the objective of improving reproducibility and evaluating separation factors under several conditions. A system that provides 75% tritium recovery on a routine basis has been developed. The principal field projects consist in: (1) A tritium study in the Coastal Plain of New Jersey indicating that layering of water of different ages occurs beneath the water table; (2) Studies in two different geologic terranes for determination of the fate of tritium fallout in the 1958 thermonuclear bomb tests; (3) Use of tritium to determine ground-water recharge to Tertiary sandstones underlying the semi-arid High Plains of New Mexico; (4) A study of tritium content of the ground water of the Snake River Plain in Idaho to develop information on the age of and rates and direction of movement of water; and (5) Use of manufactured tritium as a tracer for determination of the capacity of an underground reservoir near Carlsbad, New Mexico. (author) [French] Le Service geologique poursuit un programme de recherches qui comprend l'analyse du tritium au laboratoire et plusieurs projets executes sur le terrain et destines a verifier quelle est l'utilite du tritium dans la recherche hydrologique.

    The paper examines the most significant technical and economical indications which are emerging from design, construction and operation of the first full size nuclear power plants and which may be most helpful in shaping future additions to nuclear capacity, with particular regard to the stituation existing in Italy. The present status of manufacturers' technology and its continuous development in the course of existing projects have shown a positive trend toward reduction of both fuel-cycle and plant-component costs. This is further favoured by the increasing tendency toward bigger plant sizes and by the fact that power forecasting analyses of the electrical network suggest the opportunity of installing units of higher capacity for nuclear than for conventional plants on the basis of predicted changes in energy production expenses due to the addition of such new units. Concerning the design, construction and testing experience of existing types of stations, the paper reviews the main factors to take into account in future planning also in the light of construction and testing schedules. A certain emphasis is given to the problem of containment, because of the rewards on plant location which can be made possible by the development of very safe containers with little or no economic penalty, also taking advantage of the specific Italian situation on certain aspects of this problem. Concerning the operation experience of proven station types, the paper discusses their ability to meet network requirements and their availability, also in connection with the increasing role of nuclear capacity which is being planned in the country. Finally, the paper stresses the importance of the problem of data collection and interpretation from the three power stations now starting operation in Italy in assisting the planning of next installations. Hint is given to longer-range fuel-cycle planning on the basis of the existing framework. (author) [French] L'auteur expose les principaux enseignements qui ont ete fournis, aux points de vue technique et economique, par l'etude, la construction et l'exploitation des premieres centrales nucleaires, et qui peuvent etre particulierement utiles pour l'implantation de nouvelles centrales de ce genre dans l'avenir, notamment eu egard aux conditions qui regnent en Italie. La technologie actuelle des reacteurs et les progres qu'elle continue de faire revelent une tendance marquee vers la reduction du cout, non seulement des cycles de combustible, mais aussi des elements de la centrale. Cette evolution se trouve d'ailleurs favorisee par la tendance croissante a construire des centrales plus grandes et par le fait que l'etude du developpement du reseau electrique semble indiquer que, sur le plan economique, il y a plus d' avantage ainstaller des centrales nucleaires plus puissantes que d'augmenter la puissance des centrales classiques. Se fondant sur l'experience acquise concernant l'etu de, la construction et l'essai des divers types de centrales existantes, l'auteur donne un apercu des principaux facteurs dont il convient de tenir compte lors de l'etablissement des programmes futurs. Il insiste sur le probleme de l'isolement, vu les incidences favorables que peut avoir sur le choix du site de la centrale la mise au point d'ecrans de protection tres surs, qui puissent etre construits sans augmentation sensible du prix de revient, en tirant notamment parti, pour resoudre certains aspects de ce probleme, des conditions particulieres qui se trouvent reunies en Italie. Quant a l'experience du fonctionnement de certaines centrales d'un modele eprouve, l'auteur examine dans quelle mesure ces installations peuvent etre construites sans difficulte et satisfaire la demande du reseau; il se refere ici egalement au role croissant qu'il est prevu d'attribuer a l'energie d'origine nucleaire en Italie. Enfin, l'auteur souligne a quel point le rassemblement et l'interpretation des donnees relatives aux trois centrales, qui doivent incessamment entrer en service en Italie, aideraient a etablir les plans des installations futures. Il suggere la possibilite de prevoir des maintenant des cycles de combustible pour une plus longue periode. (author) [Spanish] En la memoria se examinan las principales consideraciones de caracter tecnico y eco nomico relativas al diseno, construccion y explotacion de las primeras centrales nucleoelectricas a plena escala, y que mas pueden ayudar a preparar los planes futuros de expansion nuclear, con especial referencia a las condiciones que reinan en Italia. El estado actual de la tecnologia de los reactores y su evolucion continua en la ejecucion de los proyectos hasta ahora realizados, muestra una neta tendencia hacia la reduccion de los costos del ciclo de combustible y de los elementos componentes de las centrales. Contribuye a esta evolucion la tendencia cada vez mas acusada a construir centrales de mayores dimensiones, y el hecho de que las previsiones acerca de las condiciones futuras de la red electrica sugieren la conveniencia de instalar centrales nucleares de mayor capacidad que las centrales clasicas, en razon de la disminucion que experimentaran los gastos de produccion gracias a la puesta en servicio de esas nuevas unidades. En lo que se refiere a la experiencia adquirida en e l diseno, construccion y pruebas de las centrales en funcionamiento, la memoria estudia los principales factores que han de tenerse en cuenta en la preparacion de planes para el futuro, tambien desde e l punto de vista de los programas de construccion y de pruebas. El autor insiste en el problema del confinamiento, en razon de la favorable influencia que sobre la elecion del emplazamiento de las centrales puede ejercer el perfeccionamiento de blindajes muy seguros, que podrian construirse sin aumento sensible del costo, teniendo en cuenta la especial situacion de Italia en lo que se refiere a ciertos aspectos del problema. En cuanto a la experiencia adquirida en la explotacion de centrales de tipo bien conocido, la memoria estudia en que medida estas instalaciones pueden construirse sin dificultades y satisfacer la demanda de la red; tambien en este aspecto se refiere al creciente papel que cabe atribuir en Italia a la energia nucleoelectrica. Por ultimo, la memoria re calca hasta que punto el acopio y la interpretacion de los datos relativos a las tres centrales nucleares que ahora comienzan a funcionar en Italia facilitarian el proyecto de instalaciones futuras. Alude a la posibilidad de establecer desde ya ciclos de combustible mas extensos.

    To assess the biological safety of foods which are of interest to the Atomic Energy Commission's irradiated food program, studies have been sponsored by the Commission's Division of Biology and Medicine since 1961. Wholesomeness, microbiological and biochemical studies have been undertaken with a view to complementing data derived from developmental, economic and technological research studies sponsored by the Commission's Division of Isotopes Development. When these aspects appear feasible for specific low-dose irradiated foods, studies are initiated to provide relevant data required by the United States Food and Drug Administration before final judgements can be made on petitions for unlimited human consumption. Toxicity studies on several species of animals which are fed diets containing up to 35 Degree-Sign (dry solids basis) of the irradiated food in question have been included in this program. Investigations of two years duration on animals (rats, dogs and chickens) provide data concerning food consumption, growth rate, enzyme systems, haematology, gross pathology and histopathology. Shorter-term studies of a confirmatory nature on two animal species (rat and dog) are employed in certain cases when the irradiated food in question is sufficiently related to foods which have previously undergone long-term toxicity studies. Results to date of chronic toxicity studies on soft-shell clams and subacute toxicity studies on strawberries, apples, pears, sweet cherries, apricots, plums and onions are discussed. Microbiological studies have been concentrated primarily on potentially pathogenic organisms. Studies have been in progress to evaluate carefully the conditions governing radiation and heat resistance, sporulation, outgrowth and toxin production of Clostridium botulinum Type E. The natural incidence of Type E organisms in certain marine products and ocean environments is being investigated. Findings in the microbiological studies are discussed. Studies to date have indicated that the general outlook for wholesomeness of irradiated foods is favourable. Toxicity evaluations are currently being initiated on bananas, mangoes and papayas. Research efforts on Clostridium botulinum, Types E and F, Salmonellae and other potentially pathogenic organisms will continue. (author) [French] Afin de determiner le degre de securite biologique des produits alimentaires qui presentent un interet pour le programme de la Commission de l'energie atomique relatif aux produits alimentaires irradies, la Division de biologie et medecine de la Commission a organise des recherches depuis 1961. Des etudes ont ete entreprises sur la comestibilite, la microbiologie et la biochimie en vue de completer les donnees fournies par les travaux dans les domaines des realisations, de l'economie et de la technique organises par la Division des isotopes de la Commission. Lorsque les resultats obtenus semblent applicables a des produits alimentaires particuliers irradies a faible dose, des etudes sont entreprises pour fournir les donnees pertinentes requises par le service de controle des produits alimentaires et pharmaceutiques des Etats-Unis avant que des decisions definitives soient prises concernant les demandes visant a autoriser la consommation illimitee d'un produit par le public. Ce programme comprenait des etudes de toxicite sur plusieurs especes d'animaux soumis a des regimes alimentaires comprenant jusqu'a 35% (en matiere solide seche) du produit alimentaire irradie considere. Des recherches d'une duree de deux ans sur des animaux (rats, chiens et poulets) fournissent des donnees sur la consommation alimentaire, la croissance, les enzymes, l'hematologie, la pathologie generale et l'histo- pathologie. Des etudes a court terme, aux fins de confirmation, sur deux especes animales (rats et chiens) sont faites dans certains cas lorsque le produit alimentaire irradie considere a suffisamment de points communs avec des produits qui ont precedemment fait l'objet d'etudes de toxicite a long terme. Les donnees fournies jusqu'a ce jour par les etudes de toxicite chronique sur une variete de palourdes et par les etudes de toxicite subaiguee sur les fraises, les pommes, les poires, les cerises, les abricots, les prunes et les oignons font l'objet d'un examen critique. Les etudes microbiologiques ont porte principalement sur les organismes potentiellement pathogenes. L'auteur a poursuivi des etudes pour proceder a une evaluation minutieuse des conditions qui regissent la resistance aux rayonnements et a la chaleur, la sporulation, le developpement et la production de toxines de Clostridium botulinum E. L'auteur fait actuellement des recherches sur l'incidence naturelle d'organismes du type E dans certains produits marins et dans le milieu marin. Les constatations faites au cours des etudes microbiologiques font l'objet d'un examen critique. Les etudes effectuees jusqu'a present ont indique que les perspectives d'ensemble concernant la comestibilite des produits alimentaires irradies sont favorables. On entreprend actuellement des evaluations de toxicite sur les bananes, les mangues et les papayes. Les recherches se poursuivront sur Clostridium botulinum E et F, Salmonellae et autres organismes pathogenes.

Se han emprendido investigaciones sobre comestibilidad y estudios microbiologicos y bioquimicos para complementar los datos proporcionados por las investigaciones experimentales, economicas y tecnologicas patrocinadas por la Division de Aplicaciones de los Isotopos de la misma Comision. Cuando se considera que esas cuestiones ofrecen perspectivas favorables en el caso de alimentos especificos sometidos a bajas dosis de, radiaciones, se emprenden encuestas para obtener la informacion que exige la Food and Drug Administration de los Estados Unidos antes de pronunciarse definitivamente sobre las peticiones de autorizacion para la venta al publico sin restricciones. Este programa comprende estudios sobre toxicidad en varias especies de animales a los que se administran dietas que contienen, hasta el 35% (sustancia solida seca) de alimentos irradiados. Se efectuan en animales (ratas, perros y pollos) investigaciones de dos anos de duracion que proporcionan datos sobre consumo de alimentos, ritmo de crecimiento, sistemas enzimaticos, hematologia, patologia e histopatologia. En algunos casos, se realizan estiidios mas cortos, con fines de comprobacion, en dos especies animales (ratas y perros), cuando el alimento irradiado tiene suficientes analogias con alimentos cuya toxicidad ha sido ya detenidamente estudiada. En la memoria se exponen los resultados de estudios sobre toxicidad cronica realizados hasta la fecha con almejas de valvas delgadas, y sobre toxicidad subaguda realizados con fresas, manzanas, peras, cerezas, albaricoques, ciruelas y cebollas. Los estudios microbiologicos versan principalmente sobre organismos potencialmente patogenos. Se estan estudiando minuciosamente las condiciones determinantes de la resistencia a las radiaciones y al calor, de la formacion de esporas, de la excrecencia y de la produccion de toxinas en el Clostridium botulinum, Tipo E. Se esta investigando la presencia, en condiciones naturales, de microorganismos del tipo E en ciertos productos y medios marinos. En la memoria se exponen las conclusiones de estos estudios microbiologicos.

    2018-01-01

    Retrieving the subsurface and deeper ocean (SDO) dynamic parameters from satellite observations is crucial for effectively understanding ocean interior anomalies and dynamic processes, but it is challenging to accurately estimate the subsurface thermal structure over the global scale from sea surface parameters. This study proposes a new approach based on Random Forest (RF) machine learning to retrieve subsurface temperature anomaly (STA) in the global ocean from multisource satellite observations including sea surface height anomaly (SSHA), sea surface temperature anomaly (SSTA), sea surface salinity anomaly (SSSA), and sea surface wind anomaly (SSWA) via in situ Argo data for RF training and testing. RF machine-learning approach can accurately retrieve the STA in the global ocean from satellite observations of sea surface parameters (SSHA, SSTA, SSSA, SSWA). The Argo STA data were used to validate the accuracy and reliability of the results from the RF model. The results indicated that SSHA, SSTA, SSSA, and SSWA together are useful parameters for detecting SDO thermal information and obtaining accurate STA estimations. The proposed method also outperformed support vector regression (SVR) in global STA estimation. It will be a useful technique for studying SDO thermal variability and its role in global climate system from global-scale satellite observations.

    The link between equatorial Atlantic Ocean variability and the coastal region of Angola-Namibia is investigated at interannual time scales from 1998 to 2012. An index of equatorial Kelvin wave activity is defined based on Prediction and Research Moored Array in the Tropical Atlantic (PIRATA). Along the equator, results show a significant correlation between interannual PIRATA monthly dynamic height anomalies, altimetric monthly Sea Surface Height Anomalies (SSHA), and SSHA calculated with an Ocean Linear Model. This allows us to interpret PIRATA records in terms of equatorial Kelvin waves. Estimated phase speed of eastward propagations from PIRATA equatorial mooring remains in agreement with the linear theory, emphasizing the dominance of the second baroclinic mode. Systematic analysis of all strong interannual equatorial SSHA shows that they precede by 1-2 months extreme interannual Sea Surface Temperature Anomalies along the African coast, which confirms the hypothesis that major warm and cold events in the Angola-Benguela current system are remotely forced by ocean atmosphere interactions in the equatorial Atlantic. Equatorial wave dynamics is at the origin of their developments. Wind anomalies in the Western Equatorial Atlantic force equatorial downwelling and upwelling Kelvin waves that propagate eastward along the equator and then poleward along the African coast triggering extreme warm and cold events, respectively. A proxy index based on linear ocean dynamics appears to be significantly more correlated with coastal variability than an index based on wind variability. Results show a seasonal phasing, with significantly higher correlations between our equatorial index and coastal SSTA in October-April season.

  7. Investigating the Potential Impact of the Surface Water and Ocean Topography (SWOT) Altimeter on Ocean Mesoscale Prediction

    NASA's Surface Water and Ocean Topography (SWOT) satellite, scheduled for launch in 2020, will provide sea surface height anomaly (SSHA) observations with a wider swath width and higher spatial resolution than current satellite altimeters. It is expected that this will help to further constrain ocean models in terms of the mesoscale circulation. In this work, this expectation is investigated by way of twin data assimilation experiments using the Navy Coastal Ocean Model Four Dimensional Variational (NCOM-4DVAR) data assimilation system using a weak constraint formulation. Here, a nature run is created from which SWOT observations are sampled, as well as along-track SSHA observations from simulated Jason-2 tracks. The simulated SWOT data has appropriate spatial coverage, resolution, and noise characteristics based on an observation-simulator program provided by the SWOT science team. The experiment is run for a three-month period during which the analysis is updated every 24 hours and each analysis is used to initialize a 96 hour forecast. The forecasts in each experiment are compared to the available nature run to determine the impact of the assimilated data. It is demonstrated here that the SWOT observations help to constrain the model mesoscale in a more consistent manner than traditional altimeter observations. The findings of this study suggest that data from SWOT may have a substantial impact on improving the ocean model analysis and forecast of mesoscale features and surface ocean transport.

  8. Variability of Suitable Habitat of Western Winter-Spring Cohort for Neon Flying Squid in the Northwest Pacific under Anomalous Environments.

    Full Text Available We developed a habitat suitability index (HSI model to evaluate the variability of suitable habitat for neon flying squid (Ommastrephes bartramii under anomalous environments in the Northwest Pacific Ocean. Commercial fisheries data from the Chinese squid-jigging vessels on the traditional fishing ground bounded by 35°-45°N and 150°-175°E from July to November during 1998-2009 were used for analyses, as well as the environmental variables including sea surface temperature (SST, chlorophyll-a (Chl-a concentration, sea surface height anomaly (SSHA and sea surface salinity (SSS. Two empirical HSI models (arithmetic mean model, AMM; geometric mean model, GMM were established according to the frequency distribution of fishing efforts. The AMM model was found to perform better than the GMM model. The AMM-based HSI model was further validated by the fishery and environmental data in 2010. The predicted HSI values in 1998 (high catch, 2008 (average catch and 2009 (low catch indicated that the squid habitat quality was strongly associated with the ENSO-induced variability in the oceanic conditions on the fishing ground. The La Niña events in 1998 tended to yield warm SST and favorable range of Chl-a concentration and SSHA, resulting in high-quality habitats for O. bartramii. While the fishing ground in the El Niño year of 2009 experienced anomalous cool waters and unfavorable range of Chl-a concentration and SSHA, leading to relatively low-quality squid habitats. Our findings suggest that the La Niña event in 1998 tended to result in more favorable habitats for O. bartramii in the Northwest Pacific with the gravity centers of fishing efforts falling within the defined suitable habitat and yielding high squid catch; whereas the El Niño event in 2009 yielded less favorable habitat areas with the fishing effort distribution mismatching the suitable habitat and a dramatic decline of the catch of O. bartramii. This study might provide some potentially

  9. Observation of baroclinic eddies southeast of Okinawa Island

    2008-01-01

    In the region southeast of Okinawa, during May to July 2001, a cyclonic and an anticyclonic eddy were observed from combined measurements of hydrocasts, an upward-looking moored acoustic Doppler current profiler (MADCP), pressure-recording inverted echo sounders (PIESs), satellite altimetry, and a coastal tide gauge. The hydrographic data showed that the lowest/highest temperature (T) and salinity (S) anomalies from a 13-year mean for the same season were respectively -3.0/+2.5℃ and -0.20/+0.15 psu at 380/500 dbar for the cyclonic/anticyclonic eddies. From the PIES data, using a gravest empirical mode method, we estimated time-varying surface dynamic height (D) anomaly referred to 2000 dbar changing from -20 to 30 cm, and time-varying T and S anomalies at 500 dbar ranging through about ±2 ℃ and ±0.2 psu, respectively. The passage of the eddies caused variations of both satellite-measured sea surface height anomaly (SSHA) and tide-gauge-measured sea level anomaly to change from about –20 to 30 cm, consistent with the D anomaly from the PIESs. Bottom pressure sensors measured no variation related to these eddy activities, which indicated that the two eddies were dominated by baro-clinicity. Time series of SSHA map confirmed that the two eddies, originating from the North Pacific Subtropical Countercurrent region near 20°―30°N and 150°―160°E, traveled about 3000 km for about 18 months with mean westward propagation speed of about 6 cm/s, before arriving at the region southeast of Okinawa Island.

    Using remote sensing of sea surface temperature (SST), sea surface height anomaly (SSHA) and chlorophyll-a (Chl-a) together with catch data, we investigated the detection and persistence of important pelagic habitat hotspots for skipjack tuna in the Gulf of Bone-Flores Sea, Indonesia. We analyzed the data for the period between the northwest and southeast monsoon 2007-2011. A pelagic hotspot index was constructed from a model of multi-spectrum satellite-based oceanographic data in relation to skipjack fishing performance. Results showed that skipjack catch per unit efforts (CPUEs) increased significantly in areas of highest pelagic hotspot indices. The distribution and dynamics of habitat hotspots were detected by the synoptic measurements of SST, SSHA and Chl-a ranging from 29.5° to 31.5°C, from 2.5 to 12.5 cm and from 0.15 to 0.35 mg m-3, respectively. Total area of hotspots consistently peaked in May. Validation of skipjack CPUE predicted by our model against observed data from 2012 was highly significant. The key pelagic habitat corresponded with the Chl-a front, which could be related to the areas of relatively high prey abundance (enhanced feeding opportunity) for skipjack. We found that the area and persistence of the potential skipjack habitat hotspots for the 5 years were clearly identified by the 0.2 mg m-3 Chl-a isopleth, suggesting that the Chl-a front provides a key oceanographic indicator for global understanding on skipjack tuna habitat hotspots in the western tropical Pacific Ocean, especially within Coral Triangle tuna.

  11. An assessment of TropFlux and NCEP air-sea fluxes on ROMS simulations over the Bay of Bengal region

    This study presents an assessment of the TropFlux and the National Centers for Environmental Prediction (NCEP) reanalysis air-sea fluxes in simulating the surface and subsurface oceanic parameters over the Bay of Bengal (BoB) region during 2002-2014 using the Regional Ocean Modelling System (ROMS). The assessment has been made by comparing the simulated fields with in-situ and satellite observations. The simulated surface and subsurface temperatures in the TropFlux forced experiment (TropFlux-E) show better agreement with the Research Moored Array for African-Asian-Australian Monsoon Analysis (RAMA) and Argo observations than the NCEP forced experiment (NCEP-E). The BoB domain averaged sea surface temperature (SST) simulated in the NCEP-E is consistently cooler than the satellite SST, with a root mean square error (RMSE) of 0.79 °C. Moreover, NCEP-E shows a limitation in simulating the observed seasonal cycle of the SST due to substantial underestimation of the pre-monsoon SST peak. These limitations are mostly due to the lower values of the NCEP net heat flux. The seasonal and interannual variations of SST in the TropFlux-E are better comparable to the observations with correlations and skills more than 0.80 and 0.90 respectively. However, SST is overestimated during summer monsoon periods mainly due to higher net heat flux. The superiority of TropFlux forcing over the NCEP reanalysis can also be seen when simulating the interannual variabilities of the magnitude and vertical extent of Wyrtki jets at two equatorial RAMA buoy locations. The jet is weaker in the NCEP-E relative to the TropFlux-E and observations. The simulated sea surface height anomalies (SSHA) from both the experiments are able to capture the regions of positive and negative SSHA with respect to satellite-derived altimeter data with better performance in the TropFlux-E. The speed of the westward propagating Rossby wave along 18°N in the TropFlux-E is found to be about 4.7 cm/s, which is close to

  12. Satellite-observed variability of phytoplankton size classes associated with a cold eddy in the South China Sea.

    Ocean-color remote sensing has been used as a tool to detect phytoplankton size classes (PSCs). In this study, a three-component model of PSC was reparameterized using seven years of pigment measurements acquired in the South China Sea (SCS). The model was then used to infer PSC in a cyclonic eddy which was observed west of Luzon Island from SeaWiFS chlorophyll-a (chla) and sea-surface height anomaly (SSHA) products. Enhanced productivity and a shift in the PSC were observed, which were likely due to upwelling of nutrient-rich water into the euphotic zone. The supply of nutrients promoted the growth of larger cells (micro- and nanoplankton), and the PSC shifted to greater sizes. However, the picoplankton were still important and contributed ∼48% to total chla concentration. In addition, PSC time series revealed a lag period of about three weeks between maximum eddy intensity and maximum chlorophyll, which may have been related to phytoplankton growth rate and duration of eddy intensity.

Tal acumulacion por los organismos marinos que el hombre consume como alimento podrian influir en el aprovechamiento o abundancia de esos organismos. Como actividad cooperativa de la U.S. Atomic Energy Comission y del U.S. Bureau of Commercial Fisheries, se estan llevando a cabo en Beaufort (North Carolina) estudios de laboratorio sobre la acumulacion, por el plancton marino, los invertebrados benticos y diversas especies de peces marinos, de una serie de radionuclidos presentes en diferentes desechos, asi como sobre los efectos biologicos que en dichos organismos ejerce la acumulacion de radiactividad. Estas investigaciones contribuyen a facilitar datos esenciales para la elaboracion de metodos de evacuacion de desechos y para asegurar la navegacion sin riesgos por las aguas costeras de buques propulsados por energia nuclear. Son asimismo utiles para el establecimiento de programas de monitoraje destinados a descubrir y evaluar los riesgos derivados de la contaminacion accidental de las aguas interiores.

    We examine interannual variability of phytoplankton blooms in northwestern Arabian Sea and Gulf of Oman. Satellite data (SeaWIFS ocean color) shows two climatological blooms in this region, a wintertime bloom peaking in February and a summertime bloom peaking in September. A pronounced anti-correlation between the AVISO sea surface height anomaly (SSHA) and chlorophyll is found during the wintertime bloom. On a regional scale, interannual variability of the wintertime bloom is thus dominated by cyclonic eddies which vary in location from one year to another. These results were compared against the outputs from three different 3-D Earth System models. We show that two coarse (1°) models with the relatively complex biogeochemistry (TOPAZ) capture the annual cycle but neither eddies nor the interannual variability. An eddy-resolving model (GFDL CM2.6) with a simpler biogeochemistry (miniBLING) displays larger interannual variability, but overestimates the wintertime bloom and captures eddy-bloom coupling in the south but not in the north. The southern part of the domain is a region with a much sharper thermocline and nutricline relatively close to the surface, in which eddies modulate diffusive nutrient supply to the surface (a mechanism not previously emphasized in the literature). We suggest that for the model to simulate the observed wintertime blooms within cyclones, it will be necessary to represent this relatively unusual nutrient structure as well as the cyclonic eddies. This is a challenge in the Northern Arabian Sea as it requires capturing the details of the outflow from the Persian Gulf.

    Phytoplankton blooms in the Western North Pacific, triggered by two successive typhoons with different intensities and translation speeds under different pre-existing oceanic conditions, were observed and analyzed using remotely sensed chlorophyll-a (Chl-a), sea surface temperature (SST), and sea surface height anomaly (SSHA) data, as well as typhoon parameters and CTD (conductivity, temperature, and depth) profiles. Typhoon Sinlaku, with relatively weaker intensity and slower translation speed, induced a stronger phytoplankton bloom than Jangmi with stronger intensity and faster translation speed (Chl-a>0.18 mg·m‒3 versus Chl-aTaiwan Island. Translation speed may be one of the important mechanisms that affect phytoplankton blooms in the study area. Pre-existing cyclonic circulations provided a relatively unstable thermodynamic structure for Sinlaku, and therefore cold water with rich nutrients could be brought up easily. The mixed-layer deepening caused by Typhoon Sinlaku, which occurred first, could have triggered an unfavorable condition for the phytoplankton bloom induced by Typhoon Jangmi which followed afterwards. The sea surface temperature cooling by Jangmi was suppressed due to the presence of the thick upper-ocean mixed-layer, which prevented the deeper cold water from being entrained into the upper-ocean mixed layer, leading to a weaker phytoplankton augment. The present study suggests that both wind (including typhoon translation speed and intensity) and pre-existing conditions (e.g., mixed-layer depths, eddies, and nutrients) play important roles in the strong phytoplankton bloom, and are responsible for the stronger phytoplankton bloom after Sinlaku's passage than that after Jangmi's passage. A new typhoon-influencing parameter is introduced that combines the effects of the typhoon forcing (including the typhoon intensity and translation speed) and the oceanic pre-condition. This parameter shows that the forcing effect of Sinlaku was stronger than

    The impacts of major tropical storms events on coastal waters include sediment resuspension, intense water column mixing, and increased delivery of terrestrial materials into coastal waters. We examined satellite imagery acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) ocean color sensor aboard the Aqua spacecraft following two major hurricane events: Hurricane Katrina, which made landfall on 29 August 2005, and Hurricane Rita, which made landfall on 24 September. MODIS Aqua true color imagery revealed high turbidity levels in shelf waters immediately following the storms indicative of intense resuspension. However, imagery following the landfall of Katrina showed relatively rapid return of shelf water mass properties to pre-storm conditions. Indeed, MODIS Aqua-derived estimates of diffuse attenuation at 490 nm (K_490) and chlorophyll (chlor_a) from mid-August prior to the landfall of Hurricane Katrina were comparable to those observed in mid-September following the storm. Regions of elevated K_490 and chlor_a were evident in offshore waters and appeared to be associated with cyclonic circulation (cold-core eddies) identified on the basis of sea surface height anomaly (SSHA). Imagery acquired shortly after Hurricane Rita made landfall showed increased water column turbidity extending over a large area of the shelf off Louisiana and Texas, consistent with intense resuspension and sediment disturbance. An interannual comparison of satellite-derived estimates of K_490 for late September and early October revealed relatively lower levels in 2005, compared to the mean for the prior three years, in the vicinity of the Mississippi River birdfoot delta. In contrast, levels above the previous three year mean were observed off Texas and Louisiana 7-10 d after the passage of Rita. The lower values of K_490 near the delta could be attributed to relatively low river discharge during the preceding months of the 2005 season. The elevated levels off Texas and

    nucleares se emplearan en grandes cantidades: basta senalar que un reactor de 500 MW, moderado por agua ligera, necesitara de 50 a 75 toneladas de material enriquecido al 3% y que es probable que en 1980 funcionen en el mundo de 200 a 300 reactores de esta potencia. La experiencia ha permitido elaborar procedimientos y practicas especiales para el control comercial de grandes cantidades de materiales baratos, como el carbon o el mineral de hierro, y de pequenas cantidades de materiales caros, como los metales preciosos. Aunque sus precios son similares a los de estos ultimos, los materiales nucleares especiales son de distinta clase y se utilizaran en cantidades mucho mayores. De todas formas, aunque quiza sea necesario recurrir a tecnicas especiales o adaptar tecnicas antiguas, en la mayoria de los casos bastara utilizar convenientemente los procedimientos ya conocidos de control de las existencias para proteger en forma adecuada las inversiones nacionales o individuales en esos materiales tan caros. En la memoria se exponen algunos criterios para el control de los materiales. Se estudian especialmente las tecnicas de control de las existencias (desde el balance contable anual hasta el inventario ffsico efectuado a diario) que resultan mas apropiadas dado el valor especffico y la cantidad total de los materiales nucleares especiales. Se presenta una matriz de soluciones para la administracion y el control de esas existencias.

Consideraciones de orden tecnico indican que, en los grandes centros de exportacion o almacenamiento de granos, la irradiacion puede competir economicamente con los metodos quimicos. Una vez establecido que el almacenamiento en grandes cantidades y los sistemas automaticos de transporte son los procedimientos mas rapidos y economicos para hacer llegar el grano a los consumidores, se puede predecir con bastante seguridad que en un futuro no muy lejano la irradiacion constituira una de las etapas del proceso de distribucion del grano. En la memoria se informa sobre algunos de los problemas que plantea la infestacion y se expone la forma en que la distribucion esta organizada en diversos paises a fin de ilustrar las ventajas que encierra la irradiacion para el tratamiento de granos en una escala internacional.
