These South Pole Seismometers Will Detect Vibrations 1.5 Miles Under the Ice - Eos The instruments will freeze into Antarctica’s ice sheet, where they will collect detailed, global-scale seismic data.

Right now, two seismometers are slowly freezing into the Antarctic Ice Sheet, housed in boreholes that extend a mile and a half below the surface.

We’ve wrapped up drilling at Crary Ice Rise with 228m of sediment core. This is an unprecedented record of the history of the West Antarctic Ice Sheet stretching back millions of years. Initial observations indicate the core includes periods of environmental change during past times of warming.

What climate change means for Greenland’s traditional Inuit lifestyle and the world Dog sled culture in northern Greenland is at risk as climate change is causing the ice and snow to melt.

Climate change "is affecting us deeply," Sara Olsvig, chair of the Inuit Circumpolar Council, said, and is amplified in the Arctic, which is "warming three to four times faster than the global average." https://to.pbs.org/4kFSlox

Antarctica sits above Earth’s strongest “gravity hole.” Now we know how it got that way. Slow rock movements deep under the Earth’s surface over tens of millions of years led to today’s Antarctic gravity hole.

A new study highlights that the timing of changes in the #Antarctic gravity low overlaps with major changes in Antarctica's climate. Future research could reveal how the shifting gravity might have encouraged the growth of the frozen continent's climate-defining ice sheets @ufresearch.bsky.social
