Iceberg B-15J Calves Iceberg Named B-15S Figure 1. MODIS image of B-15J AND B-15S dated 02 February 2007 (Please click on the pictures to view the larger image) February 02, 2007, Washington, DC-- The National Ice Center (NIC) was informed by the Antarctic Meteorological Research Center that iceberg B-15J (Figure 1) has calved a new iceberg that meets criteria for naming and tracking by the NIC. The new iceberg will be named B-15S. This iceberg marks the 18th calving event of icebergs belonging to the B-15 series. B-15S is located at 76 03' 11" South, 168 08' 35" East, near Franklin Island in the Central Ross Sea. Iceberg B-15S measures 10 nautical miles on its longest axis and 2 nautical miles on its widest axis.Iceberg names are derived from the Antarctic quadrant in which they were originally sighted. The quadrants are divided counter-clockwise in the following manner:
A = 0-90W (Bellinghausen/Weddell Sea)
B = 90W-180 (Amundsen/Eastern Ross Sea)
C = 180-90E (Western Ross Sea/Wilkesland)
D = 90E-0 (Amery/Eastern Weddell Sea)When first sighted, an iceberg's point of origin is documented by the NIC. The letter of the quadrant, along with a sequential number, is assigned to the iceberg. For example, A-53 is sequentially the 53rd iceberg tracked by the NIC in Antarctica between 0-90W (Quadrant A).
