  BAS research links ocean tides when Antarctica icebergs calve

  

  A new study has revealed that ocean tides can directly influence when large Antarctic icebergs break off from the ice shelves surrounding the continent, a process known as calving. The research marks a major step toward accurately forecasting ice loss from the Antarctic Ice Sheet and improving projections of global sea level rise.

  Huge iceberg size of Greater London, breaks off from Brunt Ice Shelf, location of BAS Halley Research Station

  

  A huge iceberg, some 1550 km², almost the size of Greater London, has broken off the 150m thick Brunt Ice Shelf. It calved after cracks that have been developing naturally over the last few years extended across the entire ice shelf, causing the new iceberg to break free. This occurred on Sunday 22 January between 19.00 and 20.00 UTC during a spring tide.
