Tell me more about a
trip to Antarctica!
Iceberg - B15A
Huge tabular icebergs
such as this one are only found in Antarctica, they
were once part of a floating ice-shelf before they broke away
from the edge. The ice-shelf would have been fed by glaciers
from the land.
They can take many years to break
up and melt once they are adrift. The larger ones are routinely
tracked by satellite as they can be significant shipping hazards.
