East Antarctica’s tectonic plate probably broke off of the supercontinent about 80 million years ago, with today’s ice sheet forming 34 million years ago. Today, the researchers write, the flat ...

The planet’s oldest ice was drilled from within the Antarctic ice sheet, and could provide new insights into the evolution of ...

Ancient river landscapes buried beneath the East Antarctic Ice Sheet have been uncovered by radar, revealing vast, flat surfaces formed over 80 million years ago before Antarctica froze. These hidden ...

Visiting a glacier — Guliya ice cap is located in western China as part of the Tibetan Plateau. It is some 22,000 feet above sea level and can reach below 40 degrees Fahrenheit at its coldest ...

Apr. 20, 2023 — The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The ...

The ice was extracted from the deep ocean in East Antarctica earlier this year and is thought to be around 1.2 million years ...

Osterberg said ice core samples showed ice ages 1 million years ago occurred every 40,000 years. Then about 800,000 years ago, ice ages jumped to occur every 100,000 years.

USGS research geologist Natalie Kehrwald pulls out an ice core extratced from a glacier on Denali in Alaska, stored in a -40 degree freezer at the National Ice Core Facility at the U.S. Geological ...

Scientists are hoping to find it. But even the scientists hunting for old ice aren't sure how long the very oldest ice might have stuck around, says John Higgins, a geochemist at Princeton University.

These ice shelves protect the ice sheets and help slow the flow of ice off the continent. Our results suggest a 3.8 metre sea level rise during the first thousand years of a 2˚C warmer ocean.

An international research team has successfully drilled and retrieved a 9,186-foot-long (2,800-meter-long) ice core from Antarctica that dates back 1.2 million years. The sample extended so deep ...

Known as the British-Irish ice sheet, the frozen mass began its relentless march about 33,000 years ago. Around 10,000 years later, the land was covered in ice half a mile thick.
