Timo Spiegel

Timo Spiegel is a Postdoctoral Researcher at the GEOMAR Helmholtz Centre for Ocean Research Kiel and the University of Hamburg, working within Topic 6 and Department 2: Marine Biogeochemistry, specifically in the Research Unit (RU) Marine Geosystems. He is currently involved in the PrimePrevention research project (until September 1, 2026), following his prior work on the APOC project focused on anthropogenic influences on the particulate organic carbon cycle in the North Sea.

His research interests center on benthic material cycles, age-depth modeling, and spatial upscaling, with a strong foundation in sediment geochemistry and marine biogeochemical processes. His work integrates field data, geochemical analysis, and modeling to understand carbon, nutrient, and elemental cycling in marine sediments, particularly in shelf seas like the Skagerrak, North Sea, and Amazon shelf.

The trends in his recent publications reveal a strong focus on human impacts on marine carbon storage, including the effects of bottom trawling and sediment resuspension on CO₂ emissions, as well as exploring ocean-based climate solutions such as alkalinity enhancement through mineral addition. His work spans disciplines including marine geology, geochemistry, climate science, and environmental engineering, often published in high-impact journals like Nature Geoscience and Communications Earth & Environment.

He has collaborated extensively with researchers across Europe and has contributed to major scientific efforts, including cruise reports and multi-institutional databases like EURO-CARBON. His career path includes a PhD in Geosciences from Christian-Albrechts-University, Kiel (2024), and prior Bachelor’s and Master’s degrees in Geosciences from the same institution.

While no formal advisees or scientific awards are listed in the provided text, his active publication record and involvement in significant research projects indicate a strong trajectory in marine biogeochemistry. He is based at GEOMAR in Kiel, Germany.
