O, C and Sr isotopic data for plankton and benthic foraminifera from DSDP Legs 26, 32, 36, and 71 sediments
A detailed d18O and d13C stratigraphy has been generated from analysis of well-preserved Albian - Early Maastrichtian foraminifera from Deep Sea Drilling Project (DSDP) Sites 511 and 327 (Falkland Plateau; ~58°S - 62°S paleolatitude) in the southern South Atlantic, and Cenomanian and Coniacian - San...

A detailed d18O and d13C stratigraphy has been generated from analysis of well-preserved Albian - Early Maastrichtian foraminifera from Deep Sea Drilling Project (DSDP) Sites 511 and 327 (Falkland Plateau; ~58°S - 62°S paleolatitude) in the southern South Atlantic, and Cenomanian and Coniacian - Santonian foraminifera from DSDP Site 258 (Naturaliste Plateau; ~58°S paleolatitude) in the southern Indian Ocean. These results, when combined with previously published Maastrichtian stable isotope data from Ocean Drilling Program (ODP) Site 690 (Weddell Sea, ~65°S paleolatitude), provide new insight into the climatic and oceanographic history of the southern high latitudes during Middle-Late Cretaceous time. The planktonic foraminifer d18O curves reveal a gradual warming of surface waters from the Albian through the Cenomanian followed by extremely warm surface waters from the Turonian through the early Campanian.
