13. Verificación de los pronosticos del modelo BRAMS centrado en la region subtropical de Sudamerica
The aim of this work is to verify the forecasts generated in the Department of Atmospheric Sciences and Ocean, University of Buenos Aires with the Brazilian model Regional Atmospheric Modeling System (BRAMS). Since year 2006, every day two different forecasts that extend for 72 hours have been performed using two nested grids with an horizontal resolution of

14. Impacto da TSM de alta resolução em simulações de previsão numérica do tempo na região da confluência Brasil-Malvinas / The impact of high resolution SST in numerical weather prediction simulations in Brazil-Malvinas confluence region
Este estudo investiga os processos de interação oceano-atmosfera afetos à temperatura da superfície do mar (TSM), como condição de contorno em um modelo de previsão numérica do tempo (PNT), na circulação atmosférica. Para tal, foi utilizado o banco de dados de TSM de alta resolução (0,05°) Operational Sea Surface Temperature and Sea Ice Analysi

15. Observação do transporte de sedimentos em suspensão ao longo do Canal Norte do rio Amazonas durante condições de baixa descarga (outubro 2008) / Observation of suspended sediment transport along North Channel of Amazon river during low discharge (October 2008)
The Amazon river, located in northernBrazil, discharges between 80,000 and 250,000 m3s-1 of water onto the adjacent shelf, creating a plume of brackish water that extends hundreds of kilometers away from the river mouth. This river also carries a large amount of fine sediments to the ocean where fluid mud has been found in the topset and upper foreset layers

17. Potenciais influências de anomalias positivas e negativas na camada de gelo marinho no mar de Ross na circulação atmosférica do Hemisfério Sul / Potential influences on the southern hemisphere atmospheric circulation of negative and positive sea ice extension anomalies in the ross sea
This study have used the CPTEC/INPE AGCM to explore the role of sea ice extent in the Ross Sea as a forcing of the asymmetric atmospheric circulation in the southern hemisphere during the austral winter (July-September), on a seasonal scale. The impacts have been assessed from the standpoint of positive and negative observed anomalies in ice extent in the Ro

18. Survey and study of graphite occurrences in the Aracoiába-Baturité graphite bearing District, CE / Levantamento e estudo das ocorrências de grafita do Distrito Grafitífero Aracoiába-Baturité, CE
The Aracoiába-Baturité Graphite-bearing District has graphitic gneiss deposits (disseminated ore) and vein (solid ore) with different genetic origins and their own physical characteristics and geological environments. The graphite gneiss ore is of sedimentary, syngenetic origin, with 1.5% to 8% C content, which is distributed along two long parallel belts,

19. Characterization of novel extracellular protease produced by marine bacterial isolate from the Indian Ocean
Out of the vast pool of enzymes, proteolytic enzymes from microorganisms are the most widely used in different industries such as detergent, food, peptide production etc. Several marine microorganisms are known to produce proteases with commercially desirable characteristics. We have isolated nine different cultures from marine samples of the Indian Ocean. A

20. A finite element model for the ocean circulation driven by wind and atmospheric heat flux
A finite element model for solving ocean circulation forced by winds and atmospheric heat fluxes is presented. It is vertically integrated 1 1/2 layer model which solves the motion and continuity hydrodynamic equations coupled with the advection-diffusion transport equation for temperature. A space-time Petrov-Galerkin formulation is used to minimize the und

21. Contribuição do aninhamento do modelo Eta no modelo de circulação geral atmosférico e acoplado oceano-atmosfera do CPTEC na previsão do clima de verão sobre a América do Sul e Atlântico Tropical / Contribution of nesting regional eta model in atmospheric and coupled ocean-atmosphere general circulation model in seasonal forecast over South America and Tropical Atlantic
This work aims to verify the advantage of nesting Eta model in global coupled ocean-atmosphere model (CGCM) in climate forecast over South America and Tropical Atlantic. Three ensembles hindcasts of ten summer (December, January and February) between 1997 and 2006. The hindcasts consist of two global models from CPTEC, one atmospheric (AGCM;T062L28) and anot

22. Eventos extremos de precipitação no leste da Amazônia. / Extreme events of rainfall in Eastern Amazon.
The aim of this study was to characterize the extreme events of rainfall in Eastern Amazon, to analyze on ocean-atmosphere conditions in global scale associated with intense occurrence periods of these events, to contribute for temporal variation comprehension of rainfall extreme events, as well as of determinant phenomena to its occurrence and to make furth

23. Relation between the Antarctic Sea ice concentration and low temperatures in South America / Relação entre a concentração de gelo marinho Antártico e a temperatura mínima na América do Sul
The Antarctic Sea Ice Concentration (ASIC) is thought to be an important element in the analysis of the world climate. However, few studies have investigated its relation to other climatic elements. Thus, the aim of this study was to verify the relation between the ASIC and low temperatures in South America through two approaches. The first, regional, invest

24. MesozooplÃncton da Bacia do Pina, Recife, Pernambuco
This study aimed to describe the structure of the mesozooplankton community from the Pina Basin, Recife, PE-Brazil. Different time scales were used: tidal, seasonal and on a spatial gradient: from the interior of the estuary, subject to continental influence, and until the connection to the ocean, with more marine influence. The zooplankton was analyzed in t
