Канал Вима является главным путем распространения Антарктической донной воды из Аргентинской котловины в Бразильскую котловину и далее на север. Канал характеризуется высокими скоростями распространения донного потока. В потоке наблюдаются высокие скорости течений до 60 см/с, хотя обычно скорости находятся в пределах 25—40 см/с. Перенос Антарктической донной воды через канал Вима меняется в пределах от 1.6 до 4.0 (±0.2) Св. За счет придонного экмановского трения ядро холодной и менее соленой воды (θ = −0.120°C) обычно прижато к восточному склону канала. Мы использовали численную модель Института вычислительной математики РАН для моделирования потока донных вод в канале Вима. Это σ-модель на основе полной системы уравнений гидродинамики с приближениями гидростатики и Буссинеска. которая лучше моделирует придонные потоки чем z-модели. Численное моделирование подтверждает измерения в океане и показывает пространственную структуру поля скорости в канале.</p></abstract><trans-abstract xml:lang="en"><p>We present a review of our long-term research of the bottom water flow in the Vema Channel in the South Atlantic. The Vema Channel is the main conduit for Antarctic Bottom Water between the Argentine and Brazil basins and further to the north. This channel is characterized by strong bottom flow. The bottom velocities are usually in the range 25—40 cm/s. The maximum measured velocities were as high as 60 cm/s. The total transport of Antarctic Bottom Water through the channel ranges from 1.6 to 4.0 (±0.2) Sv. The core of the coldest (θ = −0.120°C) and low salinity (34.665 psu) water is usually displaced to the eastern wall due to the Ekman friction. We used the numerical model for ocean circulations developed at the Institute of Numerical Mathematics to simulate the bottom flow in the Vema Channel. This is a σ-model based on the full system of thermo-hydrodynamic equations with the hydrostatic and Boussinesq approximations, which describes bottom currents more adequately than the z-models. Numerical simulations confirm the field measurements and reveal significant variability in the intensity and spatial structure of the velocity field in the channel.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Канал Вима</kwd><kwd>абиссальный поток</kwd><kwd>Антарктическая донная вода</kwd><kwd>поле скоростей</kwd><kwd>профили температуры</kwd><kwd>солености и скорости (CTD</kwd><kwd>LADCP)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Vema Channel</kwd><kwd>abyssal flow</kwd><kwd>Antarctic Bottom Water</kwd><kwd>velocity field</kwd><kwd>CTD and LADCP profiles</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by State Task № 0149-2018-0003 and by the Russian Foundation for Basic Research (grant no 17-08-00085).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wüst G.
