Bereich

The Cluster of Excellence is a joint project of the Universities of Bremen and Oldenburg and a consortium of five partner institutions: Alfred Wegener Institute Helmholtz Center for Polar and Marine Research, Max Planck Institute for Marine Microbiology, Leibniz Centre for Tropical Marine Research, Constructor University and the Hanse-Wissenschaftskolleg - Institute for Advanced Study.
Funded by the German Excellence Strategy, the cluster quantifies exchange processes at the ocean floor and investigates their role in the Earth system. The cluster's research portfolio consists of projects that (i) decipher the processes that control the transport of biogenic particles to the ocean floor under changing climate conditions, (ii) balance the transfer of carbon and other elements between the ocean floor and seawater, (iii) investigate how ecosystems on the ocean floor react to environmental changes and (iv) develop scenarios for a “warmer world” from climate archives on the ocean floor with the help of climate models.
Further information about the Cluster of Excellence can be found at https://theoceanfloor.de.
Along these central research topics, the Cluster offers a structured training for doctoral students in an interdisciplinary framework of marine biogeochemistry, marine geosciences, marine (micro)biology and (paleo)climatology.

Aufgabengebiet

The cluster offers a versatile qualification program in which doctoral researchers can strengthen their professional competence and develop their personal skills. The program offers rich opportunities for interdisciplinary exchange and collaboration across different disciplines of marine sciences, including research stays at partner institutions. Further details on the training program can be found at https://www.marum.de/en/The-Ocean-Floor/ECR-support.html.
