Figure 2. Variations of marine organic carbon (MOC) and opal weight percentage, as well as of biogenic barium in parts per million (ppm) in Angola margin sediments over the last 300,000 yr. For stratigraphic purposes, the oxygen isotopes of Globigerinoides ruber (pink) are shown. Locations of Cores GeoB 1008-3, GeoB 1016-3, and T78-33 used in the study are also shown (modified from Schneider et al., 1997).
