21 hours ago · The effective pressure under the Antarctic ice sheet describes how easily the ice flows atop the layer of water separating the ice from the bedrock. The new maps combine the bed topography, ice ...

Jan 11, 2025 · Air bubbles within a deep ice core drilled in Antarctica could reveal why Earth suddenly began to experience longer ice ages nearly 1 million years ago.

Jan 9, 2025 · An international team of scientists announced Thursday they’ve successfully drilled one of the oldest ice cores yet, penetrating nearly 2 miles (2.8 kilometers) to Antarctic bedrock to reach ice they say is at least 1.2 million years old.

Jan 9, 2025 · 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...

Jan 10, 2025 · In the quest to find the world’s oldest ice, scientists have successfully drilled a 2,800-meter (9,186-foot) long ice core, reaching where the Antarctic ice sheet meets bedrock. The...

Jan 9, 2025 · Scientists drill nearly 2 miles down to pull 1.2 million-year-old ice core from Antarctic . Analysis of the ancient ice is expected to show how Earth’s atmosphere and climate have evolved.

Jan 12, 2025 · Scientists have successfully extracted what is likely the world's oldest ice, dating back 1.2 million years, from deep within Antarctica. Working in extreme conditions of -35 degree C, the team...

Jan 14, 2025 · A colossal ice core sample drilled in Antarctica may contain the oldest, unbroken timeline of Earth's climate, stretching back more than a million years. Laid horizontally, the entire ice core's 2,800-meter (9,186-foot) length could extend across San Francisco's Golden Gate Bridge, and then some.

Dec 6, 2024 · An international team of polar researchers has discovered microbiota—a community of microorganisms—living beneath the permanently frozen ice cover of Antarctica’s Lake Enigma.

Jan 30, 2025 · An international team of Earth and environmental scientists has found evidence that the Ronne Ice Shelf in the West Antarctic did not melt during the last interglacial event, suggesting it could ...
