researchers are investigating one of the largest glaciers. It takes up a
massive chunk of Antarctica and in places could be a kilometres thick. Using aircraft
and high tech gear they surveyed 150,000 square kilometres of Totten Glacier.
Scientists have been
checking out how fast this glacier is melting. They discovered some of the water from the sea
may be tunneling underneath the glacier speeding up its melting. Donít panic
yet! It will only add a few millimetres to the sea level over the next few
decades. However there is enough ice in this monster glacier to raise the sea level
by at least three metres. Itís so big it would take many centuries to melt.
