The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

Scientists have drawn up the most accurate map of Antarctica, offering background to the continent’s response to climate ...

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

Antarctica is one of the most extreme and isolated places on Earth. Nearly the entire continent is buried beneath a massive ice sheet, locking away huge amounts of the planet’s fresh water. Because of ...

A 23-million-year record hidden beneath Antarctica’s ice may reshape forecasts of how rising temperatures affect global ...

Landscapes left behind by ancient rivers and buried beneath the Antarctic ice may affect the rate of ice loss, researchers report in Nature Geoscience. The team used radio echo sounding, a technique ...

Nearly 90 percent of Antarctica is buried under ice that averages about 1.3 miles or 2.2 kilometers thick. In some areas, the ice stacks up to nearly 3 miles or 4.8 kilometers deep. For years, ...

Deep beneath Antarctica’s ice, scientists have uncovered a geological archive that could reshape predictions of future sea-level rise.

Scientists have uncovered a new threat hiding under the floating edges of Antarctica: fast moving, stormlike swirls of water that attack the ice from below. These secretive currents, spinning in the ...

Turkish scientists say research shows risks in Antarctic region from diseases carried by migratory birds to plastic waste ...

(via PBS Terra) If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - ...
