Research / Forschung

Within the Research Unit Paleoceanography, research interests focus on the „chemical paleoceanography“:

• Foraminiferal (isotope)geochemistry: Development and application of the Mg/Ca-paleothermometry, light stable isotopes, trace elements.

• Reconstructions of late Quaternary sea surface, subsurface, and intermediate water temperatures and salinities, thermocline change, terrigenous flux, marine productivity, and (sub)surface hydrography in different ocean environments.

• Reconstructions of northern high latitude sedimentological processes, sea-ice, oceanography, and climate during the late Pleistocene.

• Ocean gateway dynamics and development of oceanic warmpools: Opening history of the Southern Gateway (Australia-Tasman-Antarctica), Pliocene closure of the Panamanian Isthmus, restriction of the Indonesian Gateway.

• Research areas: Arctic Ocean, N Atlantic, Iceland, Caribbean Sea, Gulf of Mexico, Southern Ocean (SE-Australian sector), equatorial W Pacific, SE, E, and NW Pacific, Okhotsk Sea, Bering Sea.

DN has teaching commitment at Kiel University. DN is proponent of 32 DFG and BMBF research projects since 1997, head of the stable isotope and Mg/Ca-labs, and supervised various Ph.D., M.Sc. and B.Sc. theses. DN participated, partly led, and mostly applied for 25 land and ship-expeditions.
