NERC EDS UK Polar Data Centre. https://doi.org/10.5285/b692f76f-eac8-466a-a008-32e9ba3e7b44 This dataset provides model output for 20th and 21st-century ice-ocean simulations in the Amundsen Sea. The simulations are performed with the MITgcm model at 1/10 degree resolution, including components for the ocean, sea ice, and ice shelf thermodynamics. Atmospheric forcing is provided by the CESM1 climate model for the historical period (1920-2005) and four future scenarios (2006-2100), using 5-10 ensemble members each. The open ocean boundaries are forced by either the corresponding CESM1 simulation or a present-day climatology. The simulations were completed in 2022 by Kaitlin Naughten at the British Antarctic Survey (Polar Oceans team).

Resolution is 1/10 degrees in the horizontal, with 50 levels in the vertical. Bathymetry and ice shelf topography were generated using BedMachine version 2. Atmospheric forcing is given by the CESM1 Large Ensemble (1920-2005 historical, 2006-2100 RCP 8.5, first 10 members), the CESM1 Medium Ensemble (2006-2080 RCP 4.5, first 10 members), the CESM1 Low Warming 2C Ensemble (2006-2100, first 10 members), and the CESM1 Low Warming 1.5C Ensemble (2006-2100, first 5 members). Lateral boundary conditions were derived from the corresponding CESM1 ensembles, except for the ''Fixed BC'' experiments which used the World Ocean Atlas 2018 for temperature and salinity, and the Biogeochemical Southern Ocean State Estimate iteration 122 for all other variables. Ice shelf buttressing diagnostic simulations were performed using the Ua ice flow model on the same domain. Data collection: The raw MITgcm output was converted to NetCDF using the xmitgcm python package, and then processed into timeseries, Hovmollers, and trends using the mitgcm_python library (https://github.com/knaughten/mitgcm_python). Data quality: Values which are identically zero or masked represent the land and ice shelf mask. asNeeded completed
