Polar exploration
During the new Antarctic surveys, "we'll survey some glaciers that, as far as we can tell, no one has surveyed with a laser and a radar previously, to map surface elevation and ice thickness," said Joe MacGregor, IceBridge's deputy project scientist and a glaciologist at NASA's Goddard Space Flight Center, as reported by NASA Earth Observatory. "That meets the definition of Antarctic exploration," he added.
Ice and penguins
West Antarctica, where the current survey took place, is made up of several ice-covered islands. According to NASA, you could think of it as Hawaii, but with penguins.
Losing ground
Using data gathered by the IceBridge mission, NASA researchers found that the West Antarctic Ice Sheet may be in a state of irreversible decline. The collapse of this ice sheet would directly contributing to rising sea levels.
Frozen life
It is so cold on the southernmost continent that no plants except moss and algae call it home.

Floating cubes
Icebergs, which come in all shapes and sizes, are chunks of ice that have broken off (or calved) glaciers, ice sheets or bigger icebergs. Most of the icebergs on Earth hang out either in the chilly waters surrounding Antarctica or in the North Atlantic Ocean, according to the National Snow and Ice Data Center (NSIDC).
Icy discoveries
"For nine years, NASA’s Operation IceBridge has been flying over Antarctica to measure changes in land and sea ice at the bottom of the world," NASA said in a summary of the project. More icy findings to come as scientists analyze the data and conduct more research flights.
