Prof. Jack Middelburg

is Professor for Geochemistry at the Department of Earth Sciences of University of Utrecht and Research Institute Director. His research interest is centered on the interface between environmental sciences, biogeochemistry and geosciences. As U Bremen Excellence Chair at MARUM–Center for Marine Environmental Sciences of the university he explores topics related to the marine carbon cycle, both experimentally and theoretically. One special focus: How is carbon transported through the water column, from the light-flooded zone down to the deep sea and ultimately in the ocean floor–the habitat of the deep biosphere?
