Whales Have Rebounded in the Southern Ocean. Scientists Worry Commercial Fishing Could Threaten Their Comeback.

For the second year in a row, Antarctica’s industrial krill fishing fleet halted operations ahead of schedule after reaching its seasonal catch limit.  The vessels had been harvesting the tiny shrimp-like crustaceans from waters around the Antarctic Peninsula and the South Orkney Islands, located about 400 miles north of the…

AI mapped 39,619 grounded icebergs around Antarctica for the first time; 93% are under 1 square kilometre and form a “picket fence” that helps hold sea ice in place Antarctica

AI mapped 39,619 grounded icebergs around Antarctica for the first time; 93% are under 1 square kilometre and form a “picket fence” that helps hold sea ice in place

AntarcticaRepresentative image Around Antarctica, thousands of icebergs are not drifting through the Southern Ocean. They are resting on the seafloor, anchored in shallow coastal waters and quietly influencing the movement of sea ice. For the first time, scientists have used artificial intelligence and satellite radar imagery to map this hidden…

Antarctica Gained a Record 695 Billion Tons of Ice in Just Two Years Antarctica

Antarctica Gained a Record 695 Billion Tons of Ice in Just Two Years

A rare surge in Antarctic snowfall temporarily added hundreds of billions of tons of ice to East Antarctica, even as the continent’s long-term losses continued. Credit: Shutterstock A tropical warming event helped drive record snowfall and a temporary 695-billion-ton ice gain in East Antarctica without reversing long-term Antarctic ice loss.…

Meteorite Samples Unveil Traces of Ancient Magnetic Field That May Have Helped Build the Solar System Antarctica

Meteorite Samples Unveil Traces of Ancient Magnetic Field That May Have Helped Build the Solar System

After the Solar System formed around 4.6 billion years ago, it transformed from a spherical cloud of gas and dust into a flattened disk. The cloud’s collapse eventually brought forth the sun and the planets, giving the Solar System its defining shape. While gravity is often cited as the primary…
