Reorganization of deep ocean circulation accompanying a Late Cretaceous extinction event
Article Abstract:
Radio isotopic data of ocean temperature and salinity predicts the biotic and environmental changes in the Late Cretaceous oceans of the Southern hemisphere. During biotic changes in the Late Cretaceous age, the ocean waters at the bottom cooled and became less saline, and the reorganization in the ocean circulation induced climatic changes. Inoceramid extinction is related to the palaeoceanographic change in the Late Cretaceous, and changes in the bottom-water source from low to high latitudes.

Warm tropical ocean surface and global anoxia during the mid-Cretaceous period
Article Abstract:
It has been possible to demonstrate that the thermal structure of surface waters in the western tropical Atlantic Ocean experienced significant variability around 100 Myr ago, with maximum sea surface temperatures between 3 deg C and 5 deg C warmer than at present. Stable isotope records from multiple species of well-preserve foraminifera indicate that greenhouse forcing was responsible for warmer temperatures.
