Abstract
The properties of Antarctic Bottom Water flows in the Southwest Atlantic were studied on the basis of hydrographic measurements and numerical modeling of the oceanic circulation. The CTD and LADCP profiles in the region of the Vema Channel and Santos Plateau were measured onboard the R/V “Akademik Sergey Vavilov”. Hydrographic observations at several locations over the Santos Plateau were carried out for the first time. The numerical simulation was performed using the Institute of Numerical Mathematics Ocean Model (INMOM). The observations of velocities were used for verification of the numerical model. The simulated three-dimensional velocity fields with high spatial resolution in the lower layer allow us to study the bottom currents over the entire length of the Vema Channel.
