      NEW ICEBERG BREAKS OFF OF LARSEN ICE SHELF

      Feb. 4, 2005 — A new iceberg, about twice the size of Dallas, Texas,
      has formed in the frigid waters around Antarctica, according to the
      National Ice Center in Suitland, Md. This latest development comes
      just three weeks after the world's largest iceberg, which measured
      the size of Long Island, N.Y., came close to crashing into a mammoth
      glacier, called the Drygalski Ice Tongue. (Click satellite image for

      Using satellite imagery from the Canadian Space Agency, the NIC
      discovered the new iceberg, named A-53, when it broke off from the
      Larsen Ice Shelf on January 31. It measures 35 nautical miles on its
      longest axis and 16 nautical miles on its widest axis.

      The Larsen Ice Shelf is a large sheet of glacial ice and snow,
      extending along the eastern portion of the Palmer Peninsula, within
      the westernmost section of the Weddell Sea. A-53 is centered near
      67.2S 60.5W.

      "Some icebergs of similar size that have broken off from the Larsen
      Ice Shelf have remained in the area for a while, while others have
      journeyed north," said Sean Helfrich, a NOAA meteorologist at the
      National Ice Center. "A-53 likely will not leave the Weddell Sea
      this year, and may even break off into additional icebergs sometime
      this year."

      Iceberg names are derived from the Antarctic quadrant where they are
      first sighted. When they are first spotted, the NIC documents an
      iceberg's point of origin. The iceberg is assigned the letter of the
      quadrant, along with the sequential number. For example, A-53 is
      sequentially the 53rd iceberg the NIC has tracked in Antarctica
      between 0-90 W (in the Bellinghausen/Weddell Sea) in Quadrant A.

      Located in Suitland, Md., the National Ice Center is a tri-agency
      operational center, represented by NOAA, which is part of the U.S.
      Department of Commerce, the U.S. Navy and the U.S. Coast Guard. The
      NIC mission is to provide worldwide operational ice analyses for the
      armed forces of the United States and allied nations, U.S.
      government agencies and the private sector.

      NOAA is dedicated to enhancing economic security and national safety
      through the prediction and research of weather and climate-related
      events and providing environmental stewardship of the nation's
      coastal and marine resources. NOAA is part of the U.S. Department of
      Commerce.
