Abstract

Ice shelf melting driven by a warm ocean has a critical impact on ice sheet mass balance in Antarctica and the rates of sea level rise. The Southern Ocean high-resolution (SOhi) model is a 1/24 degrees simulation developed to study ocean processes on the margin of Antarctica, containing sea ice, oceanic tides, and all ice shelves. Here, we provide melt rates from the Southern Ocean high-resolution (SOhi) simulation used in the evaluation of the model against two satellite-derived estimates. The dataset is provided as 6-hour averages in units of kg/m2/s, covering the period between March 1, 2007 and December 31, 2007. The outputs provide a comprehensive, detailed mapping of ice shelf melt rates around Antarctica, capturing areas of higher melt near grounding lines and ice fronts, and areas of freezing versus high meltwater production. Discrepancies between model and satellite estimates provide guidelines for model improvements, requirements for additional observations of ice shelf cavities, and the assembly of calibration/validation datasets to constrain the models.
