Ralf Prien

Ralf Prien is a Researcher in the Marine Chemistry Department at the Leibniz-Institute for Baltic Sea Research (IOW) in Warnemünde, Germany. His work focuses on developing and deploying oceanographic in situ sensors, particularly for chemical parameters such as nitrate, methane, and dissolved oxygen. He has led projects like the Gotland Deep Environmental Sampling Station (GODESS), which uses profiling moorings to study biogeochemical dynamics in the Baltic Sea. Prien has organized international workshops, including OceanSensors08, and is a member of professional societies like AGU and IEEE. His expertise includes sensor technology, marine observations, and ocean circulation modeling.

Education: Dr. rer. nat. in Applied Physics (1999), Christian-Albrechts-University Kiel; Dipl.-Phys. (1991), same institution. Administrative roles include Head of the Staff Council (2017–2021) and Member of the Scientific Council (2012–2015). His research spans sensor development, hydrothermal vent exploration, and understanding anoxia in semi-enclosed seas.

Key contributions include advancements in optical sensors for nitrate and H₂S, and SPR-based methane sensors. He has collaborated on major projects like the Lau Basin hydrothermal studies and Baltic Sea inflow dynamics. Over 100 peer-reviewed articles and patents reflect his technical and theoretical contributions to marine science and instrumentation.
