SUMMARY:Marine Ice in Larsen Ice Shelf - Paul Holland (British Antarctic S
 urvey)

DESCRIPTION:    It is argued that Larsen Ice Shelf contains marine ice for
 med by oceanic freezing and other mechanisms. Missing basal returns in air
 borne radar soundings and observations of a smooth and healed surface coin
 cide downstream of regions where an ocean model predicts freezing. Visible
  imagery suggests that marine ice currently stabilizes Larsen C Ice Shelf 
 and implicates failure of marine flow bands in the 2002 Larsen B Ice Shelf
  collapse. Ocean modeling indicates that any regime change towards the inc
 ursion of warmer Modified Weddell Deep Water into the Larsen C cavity coul
 d curtail basal freezing and its stabilizing influence.
