The image shows, at the lower center, a thousand - square -
mile iceberg that
calved off the huge Larsen Ice Shelf sometime in January or February.
Or the news from Antarctica this past May, when a crack in an ice shelf grew 11
miles in six days, then kept going; the break now has just three
miles to go — by the time you read this, it may already have met the open water, where it will drop into the sea one of the biggest
icebergs ever, a process known poetically as «
calving.»
While «
calving» of
icebergs is a typical phenomenon, scientists monitoring the rift said a break would leave the 21,000 - square
mile Larsen C at its most retreated position.
