Cold-water corals

Cold-water corals (CWC) occur in all oceans, within all climate zones and down to abyssal water depths. In contrast to their tropical, shallow-water counterparts that host symbiotic zooxanthellae (algae), CWCs do not depend on light. Framework-forming CWCs present biodiversity hotspots with an enhanced biodiversity compared to the adjacent seafloor. Locally these ecosystems form large 3-dimensional structures, so-called CWC mounds, that reach several kilometres in diameter and can reach hundreds of meter in height. Often they occur in clusters, referred to as mound provinces.

My main research interest is the evaluation of the CWC ecosystems as carbonate factory and their role in the global carbonate/carbon cycle. Furthermore, I am interested in the environmental controls and sedimentology of mound aggradation.
