Abstract:
The output of a 40-year coupled ice-ocean run of Smith Glacier, the adjoining Dotson and Crosson ice shelves, and the nearby continental shelf, with ocean boundary conditions forced with a climatology downscaled from a regional model of the Amundsen Sea.
Funding was provided by the NERC Standard Grant NE/M003590/1 - Is ice loss from West Antarctica driven by ocean forcing or ice and ocean feedbacks?

| Lineage: | The output was generated using the Massachusetts Institute of Technology general circulation model (www.MITgcm.org) version c67r, with changes as described in Goldberg et al (2018). Boundary conditions were downscaled from Kimura et al. for the year 2007. Bathymetry and initial ice geometry from BedMachine v1 (https://nsidc.org/data/NSIDC-0756/versions/1), and ice velocities calibrated with MEaSUREs v2 (https://nsidc.org/data/NSIDC-0484/versions/2). Methodology can be found in Goldberg, D.N., Gourmelen, N., Kimura, S., Millan, R., and Snow, K. (2019). How accurately should we model ice shelf melt rates?
