Marine Biogeochemistry

Biological Oceanography

Biological Oceanography is the study of marine organisms and their interactions with the surrounding environment. This ecological orientation makes interdisciplinary work a necessity. 

Research in the Department of Biological Oceanography at the GEOMAR focuses on biologically driven processes in the ocean and their impact on marine elemental cycling. In addition to improving our understanding of undisturbed systems, there is a growing need to examine and forecast the effects of natural and human-induced environmental changes on marine biological systems. For example, what is the impact of global warming on biological processes and what consequences are expected from CO2-induced ocean acidification? How do changes in dust deposition and iron flux into the ocean influence the ocean’s productivity and elemental turnover? These and similar questions are addressed by a combination of laboratory experiments under well-controlled conditions, field studies, including manipulative experiments in natural settings, and computer simulations of the coupled physical, chemical and biological processes.
