Wood, M., A. Khazendar, I. Fenty, K. Mankoff, A.T. Nguyen, K. Schulz, J.K. Willis, and H. Zhang, 2024: Decadal evolution of ice-ocean interactions at a large East Greenland glacier resolved at fjord scale with downscaled ocean models and observations. Geophys. Res. Lett., 51, no. 7, e2023GL107983, doi:10.1029/2023GL107983.

In recent decades, the Greenland ice sheet has been losing mass through glacier retreat and ice flow acceleration. This mass loss is linked with variations in submarine melt, yet existing ocean models are either coarse global simulations focused on decadal-scale variability or fine-scale simulations for process-based investigations. Here, we unite these scales with a framework to downscale from a global state estimate (15 km) into a regional model (3 km) that resolves circulation on the continental shelf. We further downscale into a fjord-scale model (500 m) that resolves circulation inside fjords and quantifies melt. We demonstrate this approach in Scoresby Sund, East Greenland, and find that interannual variations in submarine melt at Daugaard-Jensen glacier induced by ocean temperature variability are consistent with the decadal changes in glacier ice dynamics. This study provides a framework by which coarse-resolution models can be refined to quantify glacier submarine melt for future ice sheet projections.
