25. The impact of the use of high spatial resolution sea surface temperature data in a numerical weather prediction model / Impacto da utilização de dados de temperatura da superfície do mar de alta resolução espacial em um modelo de previsão numérica do tempo
Sea surface temperature (SST) is an important indicator of Earth´s climate. An accurate and global measurement of this parameter is of fundamental importance in applications related to climate studies, ocean-atmosphere interactions, marine ecosystem, etc. Special attention may be given to meteorological forecasts, where SST stands as an important boundary c

26. Interdecadal variability of precipitation in the Western Brazilian Amazon / Variabilidade interdecadal da precipitação na Amazonia Ocidental brasileira.
The present work focused on the interdecadal variability of precipitation in the Western Brazilian Amazon in order to help improve this knowledge and, in addition, to analyze, study and evaluate the low-frequency variability of the hydrological cycle in this region. To this end, we used data collected from conventional rain gauge stations 5, available at the

27. Ecologia e taxonomia da associaÃÃo de Copepoda Harpacticoida no talude da Bacia de Campos , RJ, Brasil
Taxonomy and ecology of Copepoda Harpacticoida from sediments of Campos Basin Slope are presented here (chapter 1), as well as the description of threee new species of Echinopsyllus (chapter 2) and a discussion concerning new insights for geographic and bathyme tric distribution of Ancorabolidae (chapter 3). A total of 44 stations were sampled along nine tra

28. Impact of atmospheric soundings over tropical Atlantic on the moisture budget of Amazonia / Impacto de sondagens atmosféricas sobre o Atlântico tropical no balanço de umidade da Amazônia
The Regional Physical-space Statistical Analysis System (RPSAS), operated by the (Brazilian) Center for Weather Forecasts and Climate Studies (CPTEC - Centro de Previsão de Tempo e Estudos Climáticos) was used in this work to evaluate the impact of assimilated geopotencial profiles from AIRS (Advanced Infrared Sounder) system on RPSAS s analyses and predic

29. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

30. Comportamento do peixe-boi (Trichechus manatus manatus) nos oceanÃrios de ItamaracÃ: manejo e condiÃÃes abiÃticas
The aim of this study was to observe and describe the behavior of marine manatees, kept in captivity for rehabilitation and further release on their natural environment. To define the behavior pattern of these animals, their affiliate courtship activities and agonistic conducts were observed, verifying the presence of associations among group members, during

31. Transporte de volume e condições hidrográficas no Canal de São Sebastião / Volume transport and hydrographic conditions in the São Sebastião Channel
Current data obtained using an "Acoustic Doppler Current Profiler " (ADCP) towed by a research boat and nearly synoptic hydrographic data were sampled in the São Sebastião Channel (SSC) during six cruises between 2001 and 2006. This study also uses ocean-surface wind fields for the South Brazil Bight (SBB) area derived from the QuikSCAT scatterometer. The

32. AVALIAÇÃO DA CAPACIDADE DE POLIMERIZAÇÃO E ELEVAÇÃO DE TEMPERATURA PRODUZIDA POR APARELHOS FOTOPOLIMERIZADORES / Curing efficiency and temperature increasement produced by photo-activation devices
Este estudo avaliou a capacidade de polimerização e a elevação de temperatura produzida por aparelhos fotopolimerizadores na polimerização das resinas compostas, FiltekZ250 (3M ESPE) e FiltekZ350 (3M ESPE). Paralelamente foi determinado o comprimento de onda e a potência dos aparelhos, utilizando-se um espectrômentro USB2000 (Ocean Optics) e um Power

33. DistribuiÃÃo dos copepoda harpacticoida da meiofauna em Ãrea de talude no litoral de Sergipe, Brasil
The study of the composition, abundance and diversity of Copepoda Harpacticoida in the slope of Sergipe, was conducted using samples obtained in April 2002 with three replicates during the Oceanographic Campaign NE2002-C1 (project FADURPE / CENPESPETROBRAS No 50.0003502.04.2). The studied stations were organized by: isobaths - 100m (stations 1, 2 and 3), 500

34. CaracterizaÃÃo GeoquÃmica e IsotÃpica de MÃrmores do Terreno Rio Capibaribe na Zona Transversal da ProvÃncia Borborema - Nordeste do Brasil
The isotopic composition (δ13C, 87Sr/86Sr e Pb-Pb) of marbles from two localities (Surubim and Caruaru) of the Caroalina-Surubim Complex (Transversal Zone, Borborema Province, NE Brazil) was used to estimate the age of sedimentation and metamorphism of the protolithic carbonate sequence. These occurrences are part of one sedimentary succession deposited

35. Contributions to South Atlantic paleoceanography in the last 25,000 years: evidence from calcareous nannofossils from northeastern brazilian slope / Nanofósseis calcários da margem continental nordeste do Brasil: uma contribuição à paleoceanografia do Atlântico Sul nos últimos 25.000 anos
This study focuses on changes in calcareous nannofossil assemblages as an evidence of paleoceanographic variability during the last 25,000 years in two deep sea piston cores from the northeastern Brazilian continental margin. To support reconstructing ancient marine environment others proxies have been applied along with the calcareous nannofossil analysis:

36. Influência do gelo marinho antártico no setor austral sudoeste do Atlântico Sul / The influence of antactic sea ice in the austral and southwest sector on the south atlantic
In this work the interaction between Antarctic sea-ice and the South Atlantic ocean (austral and southwestern sectors) is investigated. To accomplish this satellite-observed sea-ice concentration (SIC) and a coupled model from NCAR-CCSM3 (National Center for Atmospheric Research - Community Climate System Model version 3) were employed. Three 150-year simula
