Objective Mapping the bathymetry in the ROMANCHE and CHAIN fracture zones to identify the places where Antarctic Bottom Water flows from the west basin towards the east basin of the Atlantic (depths of 4,100 m). Taking hydrological and geochemical measurements in the passage areas to characterize the Deep Water and Bottom Water during their progression from West to East and highlight any mixing processes.
