NATIONAL ICE CENTER REPORTS
Three massive icebergs have calved from the Ronne Ice Shelf in the Weddell Sea, the National Ice Center in Suitland, Md., reports. The center is a tri-agency activity with representation from the U.S. Navy, NOAA, and the U.S. Coast Guard
The dimensions and locations of the icebergs are:
Iceberg A-43 was detected using the Defense Meteorological Satellite Program's Optical Linescan Sensor (DMSP OLS) infrared imagery on May 5. It is known to have calved from the Ronne Ice Shelf sometime during the afternoon or evening of May 4, as satellite imagery indicates that the ice shelf was still intact on the morning of May 4. Iceberg A-44 calved in the afternoon or evening of May 6, at or near the time that A-43 broke in half.
The National Ice Center provides worldwide operational sea ice analyses and forecasts tailored to meet the requirements of U.S. national interests. The center tracks icebergs using remotely sensed data provided in-part by satellites operated by NOAA and the Department of Defense.
Iceberg names are derived from the Antarctic quadrant in which they were originally sighted. The quadrants are divided counter-clockwise in the following manner:
When an iceberg is first sighted, the National
Ice Center documents its point of origin. The letter of the quadrant,
along with a sequential number, is assigned to the iceberg. For
example, A-44 is the 44th iceberg the ice center has found in
Antarctica Quadrant A.
