February 17, 2006, Washington D.C.-- The National Ice
Center (NIC) discovered that
iceberg B-15A (Figure 1) has calved one iceberg that meets criteria
for naming and
tracking by the NIC. The new iceberg will be named B-15Q. This iceberg
marks the
15th occurrence that a portion of B-15 has calved. B-15Q is currently
located at
68???’S 157?48’E, and measures 14 nautical miles x 03 nautical
miles.
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).
Any further calving of original berg will be suffixed sequentially
with letters, i.e. A-53 calves in two, bergs will be identified A-53A
and A-53B.
The National Ice Center is a tri-agency operational center represented
by the United States Navy (Department of Defense), the National Oceanic
and Atmospheric Administration (Department of Commerce), and the United
States Coast Guard (Department of Homeland Security). The National
Ice Center 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.
