SUMMARY:Some aspects of iceberg mechanics - Wadhams \, P\, Wagner \, T (DA
 MTP\, University of Cambridge)

DESCRIPTION:We review the factors governing the stability\, dynamics and d
 ecay of icebergs and describe areas where current models are inadequate. T
 hese include questions such as draft changes in capsizing icebergs\; icebe
 rg trajectory modelling\; the melt rate of the ice underside and ways of r
 educing it\; and wave-induced flexure and its role in the break-up of tabu
 lar icebergs. In July 2012 the authors worked on a very large (42 sq km) t
 abular iceberg in Baffin Bay\, which had calved from the Petermann Glacier
  in NW Greenland. We measured incoming swell spectrum and the iceberg resp
 onse\; also the role of buoyancy forces due to erosion of a waterline wave
  cut and the creation of an underwater ram. The iceberg broke up while we 
 were on it\, allowing an instrumental measurement of the calving event. Th
 e experiments were included in the BBC-2 film "Operation Iceberg" shown on
  Nov 1 and repeated on Nov 18.\n\n
