Fig. 12. Deep-water stratification and flow in the South Atlantic at present (top) and Last Glacial Maximum (LGM,
bottom). Recent Oi3C values of dissolved inorganic carbon are from Kroopnick (1985); LGM Ol3C -values are from
the benthic foraminifers Cibicidoides wuellerstorfi (Bickert 1992). AAIW=Antarctic Intermediate Water,
CDW=Central Deep Water, NADW=North Atlantic Deep Water, AABW=Antarctic Bottom, NCW=Northern Component Water, USCW=Upper Southern Component Water, LSCW=Lower Southern Component Water.
