Juan Ugaz is a doctoral stundent at Universidade Federal do Parana, Brazil, studying zooplankton concentrations in subsurface chlorophyll maximum layers off southeastern Brazil.

Surface drifters provide the best direct observations of the surface circulation on a global scale. Uriel Zajaczkovski is using drifters to estimate horizontal diffusivities in the South Atlantic, and their relation to the general circulation.

Jose Luiz Azevedo, a graduate student at FURG, Brazil and SACC Fellow, is visiting Dr. Doron Nof at Florida State University to carry out research related to his PhD thesis.
