The model used in this study is a regional coupled sea ice-ocean model based on the Massachusetts Institute of Technology general circulation model (MITgcm). This Arctic ocean/seaice model was applied to study the flow of water from the Chukchi Sea into the Arctic Ocean. This is motivated by the recently discovered Chukchi Slope Current. The model reproduces the observed flow across the shelf, through Barrow Canyon, and the westward-flowing Chukchi Slope Current. Mass, heat, and salt fluxes are diagnosed, pathways and the seasonal cycle are identified. Source code modifications, forcing fields, input files, and various scripts are provided to run the MITgcm and produce model fields used in publication Leng, H., M. A. Spall, R. S. Pickart, P.
