PIG Ice Shelf: First Contact

This past January NASA scientist Robert Bindschadler led an expedition to a previously untouched part of Antarctica that may be one of the best places to gauge how global warming is affecting the continent. Pine Island Glacier Ice Shelf (PIG for short) is believed to be among the most vulnerable spots ot melting on Earth, but it's also among the most remote. While satellite observations provide a wide-angle view of the action on the glacier, boots on the ground with high tech drills and sensors are needed to provide the close up shots to fill in the blanks.
