MoreIceberg was detected using satellites.
The National Ice Center, Suitland, Maryland, reported that an iceberg, 233 square miles in area, splintered away from the Pine Island Glacier in the Amundsen Sea in Antarctica. Iceberg B-21 was discovered Nov. 15 using satellites in the Defense Meteorological Satellite Program, which are operated by the Commerce Department's National Oceanic and Atmospheric Administration (NOAA). The Optical Linescan Sensor instrument was used to image the iceberg. According to imagery, the iceberg split from the Pine Island Glacier sometime between Nov. 10 and 11. The iceberg is located in the vicinity of Latitude 74.76 degrees south; Longitude102 degrees east, and has moved northwest since splitting from the Pine Island Glacier. It measures 25.3 by 9.2 statute miles. 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, B-21 is the 21st iceberg the Ice Center has found in Antarctica in Quadrant B since it began monitoring in 1976. Visit: http://www.natice.noaa.gov/home.htm.
