  • Roundup: Calving, ‘Record grooves’ and Story Maps

    Calved Greenland Iceberg  “Iceberg calving is ultimately related to the mechanical failure of ice. However, predicting mass loss from calving events remains challenging because calving takes on diferent forms under different conditions. For example, large tabular icebergs sporadically detach from freely foating ice tongues with many years of quiescence between major calving events” Read more…
