Article

The Deep Western Boundary Current (DWBC) is the main component of the deep limb of the Atlantic Meridional Overturning Circulation (AMOC). Off northeast Brazil, the DWBC breaks up into southwestward‐propagating anticyclones. In this study, we investigate the breakup mechanism with hydrographic observations, eddy‐resolving numerical model outputs, a...

In the easternmost portion of the Gulf of Guinea, Bioko Island marks the beginning of an island chain that stretches NE–SW to the Equator, where Sao Tom ́e Island sits in the path of the Equatorial Undercurrent (EUC). In this study, we explore the meso-to-large-scale effects of local flow-topography interactions that escalate from the EUC encounter...

Satellite altimeters provide quasi‐global measurements of sea surface height, and from those the vertically integrated geostrophic velocity can be directly estimated, but not its vertical structure. This study discusses whether the mesoscale (30–400 km) dynamics of three regions in the South Atlantic can be described by the surface quasi‐geostrophi...
Article
South of the Vitória-Trindade Ridge, a seamount chain off East Brazil, the Brazil Current (BC) meanders cyclonically within Tubarão Bight, occasionally forming the Vitória Eddy. It was recently found that the Intermediate Western Boundary Current (IWBC), which flows equatorward below the BC, cyclonically recirculate within Tubarão Bight. We present...

At 20.5S, the Brazil Current and the Intermediate Western Boundary Current interact with a quasi-zonal seamount chain, the Vitória-Trindade Ridge (VTR). While the mesoscale variability generated due to these western boundary currents crossing of the VTR has been recently studied, the submesoscale dynamics associated with such features have never be...

At age 101, Walter Munk passed away in 2019. His groundbreaking discoveries will still guide and amaze oceanography students for years to come. Here, we perceive patterns in rotating tank with Munk’s circulation theory aided by a Lagrangian particles tracking algorithm and numerical modeling. From information captured by video, we track the traject...
Chapter
This chapter presents an overview of the water masses and oceanic circulation of the Brazilian Continental Margin (BCM) and the adjacent abyssal plain. Six major water masses compose the stratification over 5000 m of water column in the Southwestern Atlantic: the Tropical Water (the surface water TW, 0–150 m), the South Atlantic Central Water (the...
Article
Full-text available
An intensification of the vertical shear is observed below the surface mixed layer at 21° S due to the mutually opposing flows of the Brazil Current (BC) and the Intermediate Western Boundary Current (IWBC). The propensity to develop turbulence and mixing due to vertical shear over intense stabilizing density gradients is an important characteristi...
Article
The Intermediate Western Boundary Current (IWBC) transports Antarctic Intermediate Water across the Vitória-Trindade Ridge (VTR), a seamount chain at ~20° S off Brazil. Recent studies suggest that the IWBC develops a strong cyclonic recirculation in Tubarão Bight, upstream of the VTR, with weak time dependency. We herein use new quasi-synoptic obse...

Temperature and salinity data were recorded at the slope and outer shelf of the South Brazil Bight, from November 2014 to February 2015 using an Underwater Autonomous Vehicle, specifically, a glider. During the mission, the slope was crossed 10 times, reaching depths of up to 970 m and with a sampling rate of one record per second. The density prof...
Article
Living (stained) benthic foraminifera from deep-sea stations in the Campos Basin, southeastern Brazilian continental margin, were investigated to understand their distribution patterns and ecology, as well as the oceanographic processes that control foraminiferal distribution. Sediments were collected from 1050 m to 1950 m of water depth during the...
