Antarctic Bottom Water Jets Flowing from the Vema Channel

Properties of the abyssal current Antarctic Bottom Water (AABW) from Vema Channel are studied based on temperature, salinity, and velocity profiler (CTD/LADCP) data. Previous studies over a period almost 30 years revealed that very intense AABW exists in Channel. Later, it was found this consists two branches. One branch spreads bottom channel; other is elevated western wall channel. The deepest decays after passes approximately 100 km while upper one continues further to North Atlantic source waters Canary Cabo Verde basins Atlantic. Data analysis suggested jet splits into two. these descends down canyon at 24°30′ S, (the third one) remains continental slope, indications its existence also 24°00′ S. This research analyzes pathway can be traced up latitude 24° Velocity measurements 2022 allowed us confirm branch.
