Moritz Mathis

Dr. Moritz Mathis is a Researcher at the Helmholtz-Zentrum Hereon, Institute of Coastal Systems in Geesthacht, Germany. His work focuses on global and regional ocean modeling, marine carbon cycling, and Earth system science.

• Key Projects: CLICCS (Climate, Climatic Change and Society), APOC (Anthropogenic impacts on particulate organic carbon cycling in the North Sea), RACE (Regional Atlantic Circulation and Global Change), ECODRIVE (Ecosystem Change in the North Sea).

He specializes in coastal biogeochemistry, particularly the carbon cycle in shelf and marginal seas, ocean-atmosphere CO₂ fluxes, and exchange processes between shelf seas and the open ocean. His research integrates high-resolution modeling (e.g., ICON-Coast) with temperature-dependent remineralization, sediment resuspension, and tidal current dynamics to improve climate projections.

Recent Publication: A 2022 study introducing ICON-Coast, a global ocean-biogeochemistry model with telescoping high resolution in coastal zones. This work addresses uncertainties in coastal carbon dynamics by incorporating shelf-specific processes like sediment resuspension and variable sinking particle speeds.

Collaborations: Works with Max-Planck-Institute for Meteorology (Hamburg), Max-Planck-Institute for Biogeochemistry (Jena), and University of Hamburg's Institute of Oceanography.
