Based on this drill core, the team determined the CO2 content. The boundary between the earth ages lies in the third core segment approximately between the 95 and 100 centimeter mark.

A global temperature rise between the era of the Paleocene and the Eocene approximately 56 million years ago is often used as the best natural example for the current man-made climate change. Nevertheless, its triggering mechanism is still debated. An international team of scientists led by the University of Southampton (UK) and the GEOMAR Helmholtz Centre for Ocean Research, Kiel, has now published new results in the magazine Nature, identifying strong volcanism during the opening of the North Atlantic as a key driver for the temperature increase. From MARUM, Prof. Dr. Heiko Pälike had played a key role in the investigations.
