Oct. 15, NOAA issued a press release calling attention to an iceberg
larger than the state of Delaware that had broken off the Ronne Ice Shelf,
the second largest ice shelf in Antarctica, and is now adrift in the
southern Weddell Sea. The new iceberg was identified with data from an
instrument on a satellite in the Defense Meteorological Satellite Program,
operated by NOAA. The last known iceberg of this magnitude to calve off a
Southern Hemisphere Ice Shelf was in the Ross Sea in October 1987.
Scientists at University College London believe that such breaking off, or
calving, of icebergs is an important mechanism in the disintegration of
ice shelves and a possible indicator of global warming.
