Figure F4. A. Oceanographic setting of the Leg 181 drill sites, showing position of the major ocean water masses, fronts, and current systems. B. Profile connecting all Leg 181 drill sites, showing their locations with respect to bathymetry and water mass. SAF = Subantarctic Front, STF = Subtropical Front, STD = Subtropical Divergence, DWBC = Deep Western Boundary Current, ACC = Antarctic Circumpolar Current, AAIW = Antarctic Intermediate Water, ECC = Equatorial Counter Current, SAMW= Subantarctic Mode Water, CDW = Circumpolar Deep Water.
