Figure 12. Deep-water patterns and flow in the South Atlantic during the present (A, B) and the LGM (C). A. Present salinity distributions (from Sverdrup et al., 1942). B. Distribution of d13C values in dissolved inorganic carbon (from Kroopnick, 1980). C. Distribution of d 13C values in dissolved inorganic carbon 20 k.y. ago, inferred from d13C values in benthic foraminifers of that age (from Berger and Wefer, 1996a; after Duplessy et al., 1988, and Sarnthein et al., 1994). </font>

Figure 12. Deep-water patterns and flow in the South Atlantic during the present (A, B) and the LGM (C). A. Present salinity distributions (from Sverdrup et al., 1942). B. Distribution of δ¹³C values in dissolved inorganic carbon (from Kroopnick, 1980). C. Distribution of δ¹³C values in dissolved inorganic carbon 20 k.y. ago, inferred from δ¹³C values in benthic foraminifers of that age (from Berger and Wefer, 1996a; after Duplessy et al., 1988, and Sarnthein et al., 1994).
