Multidisciplinary Observations across an Eddy Dipole in the Interaction Zone between Subtropical and Subantarctic Waters in the Southwest Atlantic

Seawater properties in two intense rings in the South Atlantic are considered. One ring separated from the Brazil Current and the other from the Malvinas Current. The analysis is based on the CTD casts and SADCP measurements from the onboard velocity profiler. The optical properties, chemical parameters, methane concentration, and biological properties such as primary production, plankton, and fish were also analyzed. Analysis of strong differences between the eddies is supplemented by observations of whales and birds in the region.

Automated summary

This study examines the seawater properties of two intense rings in the South Atlantic, which are separated from the Brazil Current and the Malvinas Current. The analysis includes optical properties, chemical parameters, methane concentration, and biological properties such as primary production, plankton, and fish. Observations of whales and birds in the region supplement the analysis of strong differences between the eddies.
