The Santos Basin (SB) is the main petroliferous basin in Brazilian continental margin and one of most studied marine areas Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially deep sea, establish baseline essential ocean variables different ecosystems for future monitoring programs. energy company Petrobras planned executed 24 oceanographic cruises over a period 2 years assess benthic (SANSED cruise) pelagic...
This study describes the hydrography and water masses of Santos Basin Continental Shelf (SBCS) during two hydrographic campaigns (SANAGU, SANSED) in 2019. Coastal Water (CW) is dominant mass southern portion SBCS, with relatively low salinity values (S<35.5 g kg–1), satellite data show that local precipitation river discharge could not account for observed cruises region domain. The explained by transport from south influenced Subtropical (STSW), which was La Plata River discharge. In...
This work describes the circulation over continental slope and São Paulo Plateau in Santos Basin during SANSED winter 2019 survey. The cruise consisted of four legs period between June, 11 August, 03 2019. observed is dominated by Atlantic southwestern boundary current regime remotely-generated anticyclones cyclones. former composed Brazil Current, Intermediate Western Boundary Current their mesoscale meanders; latter are 300km vortical rings with origin eastern side South Basin.

Aspectos interessantes do relevo submarino e da sedimentação na baía Ilha Grande foram investigados com base em sísmica de alta resolução (perfilador 7,0kHz sonar varredura lateral 100 kHz), amostras sedimentos. O fundo marinho região centro-leste canal central pode ser caracterizado por oito padrões sedimentares superficiais (ecofácies), que refletem variações textura, no teor biodetritos caráter acústico dos A disposição contatos entre as ecofácies sugere existam dominados agentes maior...
Modelos paramétricos de velocidade correntes são utilizados na literatura oceanográfica para estudos teóricos envolvendo propriedades instabilidade, ou como condições contorno e iniciais implementações regionais modelos numéricos. Estes, no entanto, foram desenvolvidos sua maioria a Corrente do Golfo (Niiler & Robinson, 1967; Luther Bane, 1985; Robinson et al., 1988; Arango 1992; Xue Mellor, 1993; Gangopadhyay 1997). O sistema formado pela Brasil (CB) Contorno Intermediária (CCI) apresenta...
The Brazil Current (BC) is a western boundary current, with an average vertical extension of 500 m, which occupies the southwestern margin Atlantic Ocean. Recently, South Bight - SBB (23º S 28º S) has been intensively explored by oil and gas industries, brought high demand in operational oceanography ocean state monitoring. In this study we present new technique based on dynamic modes oscillation, to extrapolate velocity profiles SBB, potential applications data acquired Vessel Mounted...
The South Brazil Bight is a section of the Brazilian margin mainly dominated by poleward Current flow, their meanderings and eddies. We evaluated mean mesoscale for region, an anticyclonic feature was highlighted over São Paulo Plateau. Around that feature, cyclonic eddies were also accentuated. combination these structures dominate forming eddy corridor. Using detection dataset, we reveal signal on plateau directly related to presence anticyclones. cyclones in region present both local...
<title>Abstract</title> A regional climatology of the subtropical area along South Brazil Bight is created in order to establish seasonal average hydrographic conditions over continental shelf and slope. multiscale objective analysis with a potential vorticity constraint used historical temperature salinity profiles from different databases. Relative World Ocean Atlas 2018, interpolation produced improved results, which were evaluated by comparing surface fields satellite data, also sea...
Com base em sísmica de alta resolução (perfilador 7,0kHz e sonar varredura lateral 100kHz), amostras sedimentos, foram investigados aspectos interessantes do fundo marinho na baía da Ilha Grande. Podem-se evidenciar efeitos combinados ondas correntes agindo sobre o marinho, a partir dos índices ripple (RI) paralelismo (PI2) estruturas sedimentares (formas fundo) observadas nos registros sonar. Estruturas estas associadas padrões (ecofácies). Tais são predominantemente "mega ripples"...
O vento é uma importante variável de estudo. Isso porque utilizado para muitas finalidades, além de, em casos extremos, provocar desastres naturais. Pelo ponto vista energético, ele um ente na geração energia eólica e, portanto, sua correta estimativa torna-se essencial. Ainda sobre essa temática, a do perfil vertical importante, já que os aerogeradores não se encontram superfície, mas níveis mais altos. Dessa forma, o objetivo deste trabalho foi estudar perfis offshore utilizando as...
