MITgcm Model Outputs for the ocean in Pine Island Bay between 2011 and 2021

These are MITgcm ocean model outputs under Pine Island Glacier Ice Shelf. The simulations were designed to investigate the relative role of ocean conditions and ice shelf geometric changes between 2011 and 2021. Each set of runs contains one run for each year. BOTH-2011 to BOTH-2021 contain annual runs using the ocean and geometry from the corresponding year, OCEAN-2011 to OCEAN-2021 contain annual runs using the annual ocean conditions and 2012 ice shelf geometry and GEOM-2011 to GEOM-2021 contain annual runs using the 2012 ocean conditions and the annual ice shelf geometry. The ice shelf geometries used are derived from CryoSat-2 Digital Elevation Models (Lowery et al., 2025) and converted to ice shelf draft by assuming the ice is in hydrostatic equilibrium. The ocean boundary conditions are from observations from two moorings in Pine Island Bay. The output data contain fields of potential temperature, salinity, velocity and 2d variables from the boundary layer such as freshwater flux, thermal driving and sub-ice shelf velocity.
