NEW ICEBERG IN THE ROSS SEA, NATIONAL ICE CENTER REPORTS
Iceberg B-20 was detected on September 27 using the Defense Meteorological Satellite Program's Optical Linescan Sensor infrared imagery. It is known to have broken away from the Ross Ice Shelf sometime between September 20 and 26. The exact date of splintering is currently unknown due to the extensive cloud cover that persisted over the southern Ross Sea. B-20 is located in the vicinity
of Latitude 77 degrees, 00 minutes south; Longitude 170 degrees,
42 minutes east, and has moved northwest since breaking away
from the Ross Ice Shelf. B-20 measures 30 by 11.5 statute miles.
A = 0 to 90 degrees West longitude
(Bellinghausen/Weddell Sea) 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-20 is the 20th iceberg the ice center has found in Antarctica in Quadrant B since it began monitoring in 1976. The National Ice Center, a tri-agency operational activity with representation from the U.S. Navy, NOAA, and the U.S. Coast Guard, 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. Relevant Web Sites
