ABSTRACT
Subantarctic Mode Water (SAMW), an intermediate water mass formed on the equator ward side of the Antarctic Circumpolar Current (ACC) plays an important role in ventilating the thermocline, as well as in supplying nutrients to the Southern Hemisphere and the North Atlantic Ocean. SAMW is studied using the HYbrid Coordinate Ocean Model (HYCOM) set up for the Indian Ocean including Antarctica. HYCOM output compares favorably with Argo float measurements, and HYCOM is able to simulate well an event of SAMW formation taking place in the Drake Passage, September 2003. Drift tracks from Argo floats are compared to synthetic float drift tracks simulated by HYCOM, and they are found to be in good agreement.
