Iceberg calving

    Eigencalving
    Eigencalving
    • simple formula for first-order kinematic contribution to iceberg calving
    • Volume loss through calving at ice front is proportional to the determinant of the strain rate tensor, i.e. the product of its eigenvalues.
    • Eigencalving yields multiple stable ice fronts for a number of ice shelves including Larsen A and B and the Ross Ice Shelf.
