Using current, hydrographic and satellite observations collected off Northeast Brazil around
the Fernando de Noronha Archipelago and Rocas Atoll during two oceanographic cruises …

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 …

Abstract The Rio Grande Rise (RGR) is a plateau located at 31° S in the Southwestern
Atlantic, rising from 5916 m up to 161 m below the sea level. The RGR is an important site …

Abstract Northwestward‐propagating North Brazil Current (NBC) Rings are often destroyed
upon reaching the Caribbean islands, carrying South Atlantic waters into the North Atlantic …

Western boundary currents influence the global ocean circulation and climate, whereas it
locally reaches out differently to the continental margins. This study investigates the …

The rising trend in sea surface temperature presents a threat to tropical coral reefs, causing
increased mass bleaching and mortality events. Brazilian reefs have been characterized as …

In Northeastern Brazil, successful release programmes have been implemented for the
conservation of West Indian manatees (Trichechus manatus) since the 1990s. Recently, the …

The role of symmetric instability in mixing momentum, buoyancy and poten-tial vorticity is
examined in several constituent currents of the Atlantic Meridional Overturning Circulation …

The South Equatorial Undercurrent (SEUC) is the northermost equatorial countercurrent of
the South Atlantic Ocean. Having been described in the late 1970s, this jet has been …

Ertel's potential vorticity theorem is essentially a clever combination of two conservation
principles. The result is a conserved scalar $ q $ that accurately reflects possible vorticity …
