Global simulations of ocean-sea ice-biogeochemistry model FESOM2.1-REcoM3 with eddy-permitting grid resolution and terrigenous inputs in the Arctic Ocean

nuArctic aims at increasing our understanding of the remineralization of nutrients and carbon in the Arctic Ocean and its feedbacks with the Earth System, i.e. the capacity of the Arctic Ocean to be productive and to act as a carbon sink into the future. To do so, the project is proposing modeling advances to increase the robustness of model projections. This project includes global model simulations with the global multi-resolution Finite Volume Sea Ice-Ocean Model (FESOM version 2.1) coupled to the Regulated Ecosystem Model (REcoM version 3, Gürses et al. 2024). For this project, model simulations include a representation of terrigenous inputs from both rivers and coastal erosion and were run from 1970-2100 on a model grid with eddy-permitting (4.5 km) resolution at pan-Arctic scale. The ocean-only model simulations were forced at the ocean surface with 3-hourly atmospheric output from the AWI Climate Model (Semmler et al. 2020). The project includes model experiments under four “Shared Socioeconomic Pathways” emission scenarios, a control run and sensitivity experiments. This work lead to the publication of Oziel et al. 2025 ("Climate change and terrigenous inputs decrease the efficiency of the future Arctic Ocean’s biological carbon pump » in 2025 in Nature Climate Change) which comprises a detailed description of the methods, model experiments and setups but also a publication of the source code and post-processing scripts (Oziel, 2024).
