Seals With Sensors Help Solve the Mystery of Antarctica’s Giant Sea Ice Hole

io9

Scientists studying the vast, remote waters encircling Antarctica frequently enlist the help of elephant seals, sticking sensors on their heads that collect data on temperature and salinity. Now, these flippered field assistants, along with robotic floats that collect similar intel, have been conscripted to help solve…

A Quarter of West Antarctica’s Ice Is Now Unstable, Study Finds

io9

Stop me if you’ve heard this one before but the ice is screwed. New findings released on Thursday reveal that a quarter of the ice sheets in West Antarctica, the most vulnerable part of the continent, have destabilized. Ice loss has sped up fivefold across the region’s most imperiled glaciers in just 25 years.

Scientists Just Melted a Hole Through 3,500 Feet of Ice to Reach a Mysterious Antarctic Lake

io9

While you were baking cookies and binging Netflix shows over Christmas, a team of about 50 scientists, drillers, and support staff was attempting to punch through nearly 4,000 feet of ice to access an Antarctic subglacial lake for just the second time in human history. And folks, they did it.

Scientists Weighed the Earth Using Ghostly Particles From Space

io9

Scientists have to use some roundabout methods to weigh the Earth and measure what’s inside it—typically, they’ve used sound waves and the strength of gravity to make their calculations. But one team has weighed the Earth in a whole new way: by measuring mysterious cosmic particles that pass through it.
