Regional Ocean Modeling System output for glacier geoengineering impact assessment in Greenland fjords

This dataset contains time series output from Regional Ocean Modeling System (ROMS) simulations investigating the impact of fjord sill depth on circulation and biogeochemistry in a Greenland fjord system. The data includes three scenarios with different sill depths (250m baseline, 200m, and 100m) and provides fjord-averaged temperature, dissolved inorganic nitrogen (DIN) fluxes at the fjord mouth, cumulative DIN export, and mean DIN concentrations at the fjord outlet. Temperature differences between the baseline and modified sill scenarios are also included. These results demonstrate how fjord sill depth controls water mass exchange, heat transport, and nutrient cycling in glacial fjord systems. Data is provided as a MATLAB structure with metadata describing variables and scenarios.
