Disappearing Arctic Sea Ice - Melting Polar Ice Cap
What Scientists Are Seeing Over Antarctica
NASA's Operation IceBridge has launched its Antarctic 2012 campaign,
flying high-priority missions measuring polar ice from a base of
operations at the tip of Patagonia on the Strait of Magellan. They have
even made a return visit to the Pine Island Glacier, the site of last
year's discovery of a massive rift in the ice.
Sea ice doesn't
always hold the allure of a massive ice sheet, or a crevassed blue
glacier spilling between mountains, but it comes in array of shapes and
sizes and has its own ephemeral beauty. Operation IceBridge studies sea
ice at both poles, and also runs across interesting formations on route
to other targets. Operation IceBridge returned to the Pine Island
Glacier twice in 2012, and NASA glaciologist Kelly Brunt discusses the
implications of the glacier's impending calving event.
Operation
IceBridge has now returned to the Pine Island Glacier, not once, but
twice in 2012. And the year-old giant crack in the glacier, poised to
create an iceberg the size of New York City? Well it's still there, and
that iceberg has yet to break free. But the rift has grown longer, much
wider, and spawned a secondary crack. Before we talk about when that
mighty berg will be born, let's take a look at the IceBridge missions
themselves. IceBridge's first return to the region was a high altitude
flight over the entire region, including the Thwaites, Smith, and Kohler
glaciers. After this campaign is over, scientists will be able to
compare this broad survey with previous years' measurements in order to
better document the rapid and widespread changes in the region over
time.
