Walter Geibert

Dr. Walter Geibert is a Researcher in the Marine Geochemistry department at the Alfred Wegener Institute, specializing in naturally occurring radionuclides, nutrient cycles, and paleoceanography. He holds key roles such as Head of the Radiochemistry/Inorganic Chemistry Lab and Deputy Section Head. His research focuses on ocean biogeochemical processes, including trace metal dynamics, sediment geochemistry, and climate-driven changes in marine systems.

• Education: Not explicitly stated in the provided text.
• Roles: Radiation Safety Officer, Ombudsperson for PhD students, and Member of the GEOTRACES Scientific Steering Committee.

Research interests span radionuclide distributions in oceans, nutrient fluxes, paleoceanographic reconstructions, and development of new proxies for oceanographic studies. He has led numerous expeditions, including PS144 and MOSAiC, contributing to Arctic and Antarctic oceanography.

Publications highlight studies on sediment dynamics, carbon burial, and isotopic tracers, with a focus on polar regions and the Southern Ocean. His work integrates lab-based analyses with field data to understand long-term environmental changes.
