1. The variability of the subantarctic front and the Southern Hemisphere atmospheric jet
Abstract The latitudinal variations of the Subantarctic Front (SAF) and Southern Hemisphere atmospheric jet were investigated for the period of 1993-2016. Zonal wind velocity, sea surface height and temperature data were used to identify these features over the South Atlantic, South Pacific and Indian Oceans individually. During this period, the atmospheric

2. Salinity and stable oxygen isotope relationship in the Southwestern Atlantic: constraints to paleoclimate reconstructions
Abstract: Stable isotopes have been widely used in the literature both to discuss current ocean circulation processes, as well as to reconstitute paleoceanographic parameters. The distribution of oxygen and deuterium stable isotopes in seawater (δ18Osw and δDsw) at the Western Tropical South Atlantic border was investigated to better understand the main fr

3. Modelos Acoplados do IPCC (CMIP3-CMIP5) e o Gradiente Meridional de Anomalias de Temperatura da Superfície do Mar (TSM) no Oceano Atlântico Tropical
Resumo Este estudo investigou a sensibilidade de modelos acoplados oceano-atmosfera do CMIP3 e do CMIP5 para o período de 1979-1999 em simular a magnitude do gradiente meridional de anomalias de Temperaturas da Superfície do Mar (TSM) no Atlântico Tropical. Nos resultados são apresentadas análises comparativas para este gradiente meridional de anomalias

4. Pessoas, manatins e o ambiente aquático na América moderna: confluência e divergência nas interações históricas entre humanos e animais
RESUMO Com uma distribuição geográfica histórica alargada em zonas costeiras, ambientes de transição e fluviais do Oceano Atlântico tropical, o manatim (manati das Índias Ocidentais, peixe-boi ou iguaragua do Brasil colonial) era bastante valorizado. As fontes documentais e iconográficas dos séculos XVI e XVII mostram-nos que era usado como aliment

5. On the occurrence and ecology of Glaucus atlanticus Forster, 1777 (Mollusca: Nudibranchia) along the Southwestern Atlantic coast
Abstract: Unlike the majority of the nudibranchs, Glaucidae lives adrift at the sea surface within Tropical and Subtropical ocean basins, feeding on cnidarians or using them to attach their egg strings as a reproductive strategy. The latitudinal distribution of Glaucus atlanticus throughout the Brazilian Province is influenced by the Brazil current and, in i

6. Large-Scale Spatial and Temporal Variability of Larval Fish Assemblages in the Tropical Atlantic Ocean
Abstract This study investigated the large-scale spatial and temporal variability of larval fish assemblages in the west tropical Atlantic Ocean. The sampling was performed during four expeditions. Identification resulted in 100 taxa (64 families, 19 orders and 17 suborders). During the four periods, 80% of the total larvae taken represented eight characteri

7. Vertical distribution and structure of copepod (Arthropoda: Copepoda) assemblages in two different seasons down to 1,200 m in the tropical Southwestern Atlantic
ABSTRACT The vertical distribution of copepod assemblages, ascertained from the surface down to 1,200 m, was investigated during two sampling periods (rainy and dry seasons), at four depths, in the oligotrophic waters of the southwestern Atlantic Ocean. Total density, diversity, and richness differed among sampling depths. Copepod density decreased with dept

8. Molecular evidence of two cryptic species of Stramonita (Mollusca, Muricidae) in the southeastern Atlantic coast of Brazil
Abstract Snails of the genus Stramonita are commonly found in the rocky intertidal habitat of the western Atlantic Ocean coast. They belong to a monophyletic taxon that occurs along the tropical and warm-temperate Atlantic and eastern Pacific rocky shores. This genus comprises different valid species and members of the S. haemastoma complex. In the present s

9. Zoogeography of Elasmobranchs in the Colombian Pacific Ocean and Caribbean Sea
ABSTRACT In order to investigate zoogeographical patterns of the marine elasmobranch species of Colombia, species richness of the Pacific and Caribbean and their subareas (Coastal Pacific, Oceanic Pacific, Coastal Caribbean, Oceanic Caribbean) was analyzed. The areas shared 10 families, 10 genera and 16 species of sharks, and eight families, three genera and

10. The first occurrence of the Order Mormonilloida (Copepoda) in the Tropical Southwest Atlantic Ocean
Esta nota é o primeiro registro da ocorrência de Mormonilla phasma(Copepoda) no Sudoeste do Oceano Atlântico Tropical. Indivíduos fêmeas foram encontrados em águas superficiais na quebra da plataforma do estado do Rio Grande do Norte (Nordeste do Brasil) e entre 60 e 100 m de profundidade, na camada epipelágica ao largo do Arquipélago de São Pedro e

11. Vanadium-binding protein in marine plankton from tropical south atlantic ocean
Nós investigamos o papel do plâncton no ciclo do vanádio (V) em Cabo Frio, Rio de Janeiro, Brasil, uma região com alta concentração de V nas partículas atmosféricas, devido ao aerossol marinho. As concentrações de V no plâncton variaram de 0,08-20,9 µg g-1 (zooplâncton), 0,1-28,4 µg g-1 (fitoplâncton > 64 µm) e < 0,0005-49,0 µg g¹ (pequeno

12. Impactos de El Niño y La Niña en las lluvias del Perú (1965-2007)
The impacts of El Niño (EN) and La Niña (LN) in rainfall in Peru are evaluated using monthly data (1965-2007) of 155 stations distributed over the three hydrographic drainages of Peru: 85 in the Pacific (VP), 21 in the Lake Titicaca (VT) and 49 in the Amazon (VA). To classify El Niño and La Niña is used the Index Troup Southern Oscillation (SOI) based on
