Abstract

Presents planktic and benthic foraminiferal isotopic data from two almost biostratigraphically complete sections at ODP Site 738 in the antarctic Indian Ocean and at Nye Klov in Denmark. These data suggest that planktic carbonate δ 13 C values in high latitudes may not have decreased dramatically at the K/T boundary; thus, surface-water productivity may not have been reduced as much as in low and middle latitude. These data suggest that the environmental effects of the K/T boundary may have been less severe in the high-latitude oceans than in tropical and subtropical regions. -from Authors
