Figure F6. CCD estimate based on Sites 1218, 1219, and 1220 over CAE-3. Sites 1218 and 1220 were at the equator at 40 Ma, while Site 1219 was at ~2°S. The lack of CaCO3 at Site 1220 is in contradiction with the large changes that occur at both Sites 1218 and 1219. The Site 1220 data indicate either sediment bypassing at Site 1220 or somewhat higher CaCO3 production away from the equator. MAR = mass accumulation rate.
