record iceberg seen in Antarctic
America V, Antarctica, Nov. 17- The U.S.S. Glacier, the Navy's
most powerful icebreaker, has sighted an iceberg more than twice
the size of Connecticut."
berg was sighted by the Glacier early this week about 150 miles
west of Scott Island. The ship reported it was 60 miles wide and
208 miles long- or more than 12,000 square miles, as against
to the United States Navy sailing directions for Antarctica, the
largest berg hitherto reported was that seen Jan. 7, 1927, off
Clarence Island by the Norwegian whale catcher Obb I. The ship
said it was 130 feet high and roughly 100 miles long. Both these
gargantuan icebergs were of the tabular variety typical of
Antarctica. This type consists of a section of continental ice
sheet that has pushed out a great distance over the sea before
breaking off a situation that does not arise in the Arctic.
The tabular berg has a flat top and is of uniform height,
drawing roughly 700 feet of water."
was the "calving" that is, breaking off, of such an
immense wafer of ice at the Bay of Whales sometime between 1948
and 1955 that deprived the original Little America of its
harbor. Hence this camp, built early this year, had to be set up
on Kainan Bay, thrity-five miles to the east."
iceberg breaks off Antarctica
iceberg 124 miles long and more than 19 miles wide has broken
off Antarctica's Ross Ice Shelf. The
iceberg is the largest to break off Antarctica since a March
2002 berg that was 170 miles long and 25 miles wide.
- B-15A, C-18 and C-19
B-15A, which broke off in March 2000, sits at a right angle to
C-19, which broke away from the Ross Ice Shelf last last week.
C-18, which broke off earlier last week, is at the eastern end
of C-19. The U.S. McMurdo Station is on Ross Island.
Saturday the National Ice Center in Washington, D.C., confirmed
the size and position of the new berg and labeled it
"C-19" because it was the 19th iceberg to break off in
its part of Antarctica since tracking began.
