Research Profile
The biogeochemical cycling of nitrogen compounds and related elements is a major focus of my work. Since almost two decades I have been leading a group of students and PostDocs supported by various projects funded by the German Science Foundation, European Union, the Ministry of Science and Technology plus the basic institutional funding. Several projects in the past focused on nitrogen fixation activity in the Baltic Sea, the South China Sea off Vietnam and the Atlantic Ocean under the present situation and under ocean acidification scenarios. Research in the Baltic Sea concentrated on budgets of nitrogen for the entire Sea, and on nitrogen cycling in coastal and estuarine waters. We often use stable isotope signatures in environmental samples to better understand sources of nitrogen compounds or nitrogen turnover processes. Furthermore, we use labelled isotope compounds to measure rates like nitrogen fixation or nitrification. For more information please visit our website of the group “Marine N-cycle”.
Special exhibition opening on July 25, 2025, at the International Maritime Museum Hamburg
Outstanding achievements by renowned women in marine research have long remained hidden. A special exhibition opening on July 25, 2025, at the International Maritime Museum Hamburg will offer exciting insights into the creativity of these female scientists until the end of the year. Motto: "Breaking the Surface. Women in Marine Research."

The 2022 Björn Carlson Baltic Sea Prize is awarded to Professor Maren Voss of the Leibniz Institute for Baltic Sea Research in Warnemünde, Germany.
Professor Maren Voss is being awarded the prize for her groundbreaking research on the importance of marine nitrogen, particularly in the Baltic Sea. Professor Voss realised early on that nitrogen plays a vital role in Baltic eutrophication and has used advanced isotope analyses to map the transformation processes and sources of nitrogen in the Sea. Her research has increased the focus on nitrogen in efforts to counteract Baltic Sea eutrophication.
