Ice core samples show West Antarctic ice sheet survived the last interglacial event. Story by Bob Yirka • 1w. A n international team of Earth and environmental scientists has found evidence that ...

The ice core sample contained two distinct layers, with the top layer dating to around 2.95 million years old. Beneath this layer, the team found the ice dated back to between 4.3 and 5.1 million ...

The sample extended so deep that it reached the bedrock beneath the Antarctic Ice Sheet. The core, nearly as long as 25 soccer fields end to end or six and a half times taller than the Empire ...

The fourth Antarctic campaign of the Beyond EPICA-Oldest Ice project has achieved a historic milestone this week, by successfully drilling a 2800-metre-long ice core, consisting of ice from the ...

This work makes krypton-81 dating feasible for small ice core samples. The USTC team is now working with glaciologists both in China and abroad to systematically apply the method to basal ice from ...

The team, with members from 12 European scientific institutions, drilled and retrieved a 9,186-foot-long (2,800-meter) ice core from the Antarctic ice sheet. The sample extended so deep that ...

At an extremely remote Antarctic outpost, scientists have unearthed a pristine sample of our planet's history. It's an ice core 2,800 meters, or some 1.7 miles, long.

What an ancient ice core from Antarctica can tell us about our climate’s past and future ... He wasn't involved in this project and says this new sample is more than just a history lesson.

Incredible. Natty Ice. An international team of scientists have drilled nearly two miles down into the Antarctic bedrock, extracting an ice core sample that's estimated to be at least 1.2 million ...

At 1.2-million-years-old, a newly uncovered Antarctic ice core represents the oldest known ice on the planet. The 1.7 mile-long ice core was recovered from over 9,000 feet (2,800 meters) deep ...
