ABSTRACT. Potential energy released from the capsize of ice-shelf fragments (icebergs) is the
immediate driver of the brief explosive phase of ice-shelf disintegration along the Antarctic Peninsula
(e.g. the Larsen A, Larsen B and Wilkins ice shelves). The majority of this energy powers the rapidly
expanding plume of ice-shelf fragments that expands outward into the open ocean; a smaller fraction of
this energy goes into surface gravity waves and other dynamic interactions between ice and water that
can sustain the continued fragmentation and break-up of the original ice shelf. As an initial approach to
