We consider measurements of currents north of the Vema Channel with the goal to find continuations of the bottom water flow after Antarctic Bottom Water leaves the Vema Channel and discharges to the Brazil Basin. We found two smaller channels of the continuation of this flow, one of which is directed to the east and the other to the north. The flow of the coldest water and the magnitudes of its velocity are important for the sedimentation processes, which occur in this region. We analyze the hydrology of the bottom water needed to compare the conditions of environment and the structure of sediments.

Acoustically stratified seismic images are widely used in studies of sedimentation mechanisms producing thick sedimentary aprons on continental rises. However, insuffcient vertical resolution of seismic records commonly restricts a more detailed interpretation of individual reflectors within accumulations to reconstruct specifc short‐term sedimentological events. (Reflectors correspond to boundaries between sedimentary layers with different acoustic properties and are imaged in seismic records as continuous lines.) Very high resolution (VHR) seismic profiling conducted during Cruise 33 of the Russian research vessel Akademik Ioffe (2011) provided correlation of acoustic reflectors, distanced from one another by less than 50 centimeters, with thin sedimentary layers recovered by gravity cores.
