Investigations of sediment cores GL-1248 and GeoB16202-2 to reveal changes in upper ocean stratification in the western equatorial Atlantic ...
Surface ocean circulation in the western equatorial Atlantic is mainly wind-driven and plays a major role for the transport of warm waters to the North Atlantic. Past changes in the strength and direction of the trade winds are well documented, but the response of the western equatorial Atlantic cir...

Surface ocean circulation in the western equatorial Atlantic is mainly wind-driven and plays a major role for the transport of warm waters to the North Atlantic. Past changes in the strength and direction of the trade winds are well documented, but the response of the western equatorial Atlantic circulation and water column structure to these changes is unclear. Here, we used the difference between the stable isotopic oxygen composition of two species of planktonic foraminifera (Globigerinoides ruber white and Neogloboquadrina dutertrei) from two sediment cores collected off northeastern Brazil to investigate millennial- and orbital-scale changes in upper ocean stratification since the Last Interglacial.
