The Oceans Biological Carbon


The Ocean's Biological Carbon Pump as Part of the Global Carbon Cycle

Susanne Neuer is an Associate Professor in the School of Life Sciences at Arizona State University. She received a Bachelors degree in Biology from the University of Kiel, Germany, a MS in Oceanography from the University of Washington, and a Ph.D. from the College of Ocean and Atmospheric Sciences at Oregon State University. She completed postdoctoral training in marine biogeosciences at the University of Bremen in Germany before coming to Arizona State University in 2000. Her research bridges biogeochemistry and plankton ecology, particularly focusing on the biological carbon pump, its relationship to plankton community composition and surface productivity. Most of this e-Lecture was completed while a Fellow at the Hanse Wissenschaftskolleg (Advanced Research Institute) in Delmenhorst, Germany, in 2013.

Morten Iversen is head of the Helmholtz Young Investigator Group “SeaPump - Seasonal and regional food web interactions with the biological pump” at the Alfred Wegener Institute for Polar and Marine Research, the Marum - Center for Marine Environmental Sciences, and the University of Bremen. He received a Bachelor’s degree in Environmental Biology from Roskilde University, Denmark, a Master’s degree in Biological Oceanography from the University of Kiel, Germany and University of Southern Denmark, and a Ph.D. from the University of Bremen, Max Planck Institute for Marine Microbiology, and the Alfred Wegener Institute for Polar and Marine Research, Germany. Through a unique combination of method and technology development, field studies, laboratory experiments, and modelling, Morten’s research aims to understand how vertical carbon fluxes are regulated in the ocean. This research links small-scale biological processes, e.g. microbial degradation and zooplankton flux-feeding, with large-scale transport processes at high spatial and temporal resolution using hydro-acoustics, in situ camera systems and gels in sediment traps to determine settling particle sources, and their degradation and preservation in the water column. With this novel approach he hopes to gain new mechanistic understanding of the physical, chemical, and biological processes regulating the ocean’s biological carbon pump from the sunlit surface layer to the dark, deep ocean.

Bremen, Germany

Gerhard Fischer is a research scientist and lecturer in the Marine Geology Department and the MARUM at Bremen University, Germany. He received his diploma in Geology at the Technical University in Darmstadt and then moved to the Geosciences Department at Kiel University in 1984. He completed his Ph.D. thesis at the University of Bremen in 1989 in the field of stable carbon isotope geochemistry. Later he was working in a collaborative research project with particle fluxes and stable isotopes in the Atlantic Ocean. At present he is involved in studies of the biological pump in the coastal upwelling of Mauritania within the DFG research center “The Ocean in the Earth System” at MARUM. He offers lectures, exercises and field trips for graduate and undergraduate students in the field of general, marine and historical geology.
