Air bubbles within a deep ice core drilled in Antarctica could reveal why Earth suddenly began to experience longer ice ages ...

That meant the eruption likely took place in the Northern Hemisphere. The Greenland ice cores included ash layers and ...

Scientists Baffled After Recovering 1.7-Mile-Long Ice Samples Dating Back 1.2 Million Years, Call It a ‘Time Machine’ ...

An international team of Earth and environmental scientists has found evidence that the Ronne Ice Shelf in the West Antarctic ...

By analyzing sulfur and volcanic ash entrained in ice cores, researchers pinpointed a caldera in the remote Kuril Islands as ...

Ice cores can show how temperatures have fluctuated ... The deeper the cores go, the more history they contain — and the icy layers could also solve some of the biggest questions about mysteriou ...

Using ice core samples, researchers linked a natural disaster with a trove of nearly 5,000-year-old artifacts discovered at ...

Scientists in the Antarctic have successfully extracted the world's oldest ice—drilling down 1.7 miles for ice samples a ...

However, that sample was collected closer to the surface, thanks to natural processes that push up layers of older blue ice. The new ice core represents the longest continuous record of Earth’s ...

Researchers recently solved that puzzle by sampling ice cores in Greenland, peering back in time through the cores’ layers to examine sulfur isotopes, grains of ash and tiny volcanic glass ...

The team had to work to prevent drill failures and ensure that the electromechanical core drill was progressing through the ice layers. Each meter of ice can contain as many as 13,000 years of ...
