Iceberg takes on global warming
Of course, satellite coverage is so recent that we have no reasonable historical baseline for how long it takes for an iceberg to reach Macquarie Island:
Australian Antarctic Division researchers working on Macquarie Island, about 930 miles southeast of Tasmania, first saw the iceberg last Thursday [November 5, 2009] about 5 miles off the northwest coast of the island.
The iceberg, about 160 feet high and 1,640 feet long, is probably part of one of several larger icebergs that broke off Antarctica's Ross Ice Shelf between 2000 and 2002, Australian Antarctic Division glaciologist Neal Young said.
....
In 2000, several massive icebergs broke off from Antarctica's Ross Ice Shelf and the Ronne Ice Shelf. The first iceberg was about 190 miles long and 23 miles wide. Those icebergs are now drifting away from Antarctica.
Was the tracking really so bad that it's not known when this iceberg launched?
