Probing the Antarctic

The great ice-covered continent has been a mystery to scientists in many places, simply because the ice shelf may extend many kilometers into the oceans and there's no practical way to study the waters and land underneath it. Many expeditions with the latest tools have nibbled at the edges, but Nature herself can sometimes lend a hand. Calving evens affecting large chunks of the ice shelf are worrisome to climatologist, but they offer many opportunities for marine biologists and others who want to study the newly-opened areas. This kind of opportunity is being seized now, as the British Antarctic Survey is out to see what the massive iceberg A68 has exposed.  Good luck, chaps!
