Iceberg larger that island of Guam drifts away from Antarctic glacier
Washington: Scientists have observed an iceberg bigger than the island of Guam, which is slowly moving away from an Antarctic glacier.
NASA scientist Kelly Brunt said that it is more a wonder than a worry and is not a threat to shipping or sea-level rise, CBS News reported.
Brunt said that the iceberg, named B-31, is about 255 square miles, roughly six times as big as Manhattan and as much as 1,600 feet thick.
It broke off from the critical Pine Island Glacier last fall and researchers have been watching it move away ever since.
She said that it is completely natural for icebergs to split off from glacier s in Antarctica, however this calving does shrink the Pine Island Glacier beyond its 30-year normal.
