Palaeoceanography of Cretaceous to Cenozoic Oceans

Torsten Bickert, Jochen Kuss, Robert Speijer (EUROPROX, RCOM)


Objectives
Over the course of the Cretaceous to the Cenozoic, the earth system changed from a non-glacial into a glacial state. This began with the formation of a permanent ice sheet on the Antarctic continent, resulting from the thermal insulation of the Southern Ocean from the subtropics, and ended in the Late Tertiary by the onset of ice growth in the northern hemisphere. This climatic development, however, was not gradual, instead it occurred in step-like stages. The changing boundary conditions, particularly the horizontal and vertical tectonic changes (opening or closing of oceanic gateways, mountain building episodes) had significant impacts on ocean circulation and climate evolution.

The aim of the course is to present and discuss recent paleoceanographic studies of the Cretaceous to Cenozoic world oceans, and to convey actual methods being used to reconstruct ocean circulation and productivity of shallow marine as well as of pelagic realms.
