Chileans receive mistaken tsunami warning following Antarctic quake

This picture released by Chile’s Air Force shows the Eduardo Frei Antarctic base at the Fildes Peninsula, west of King George Island, in May 2020 A 7.1-magnitude earthquake that struck Saturday off the coast of Antarctica triggered a tsunami warning but panic ensued when a message to abandon coastal areas was sent to a large […]

Study shows how network of marine protected areas could help safeguard Antarctic penguins

New research led by BirdLife International, the University of East Anglia (UEA) and British Antarctic Survey highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins. The findings, published today in the journal Frontiers in Marine Science, show that if all […]

Gravity Data Reveal Unexpected Antarctic Ice Variations

As more coastal communities face the looming threat of rising sea levels, it’s more important than ever to accurately predict changes in one of the greatest potential sources of sea level rise—the melting of Antarctica’s massive ice sheet. Recently, scientists analyzed nearly 2 decades’ worth of data from sensitive NASA satellites documenting mass […]

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers — ScienceDaily

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research. Atmospheric rivers are long, narrow jets of air that […]

The world’s largest iceberg is on a collision course with an Antarctic penguin refuge

The world’s largest iceberg may be on a collision course with a wildlife haven in the South Atlantic Ocean, researchers at the British Antarctic Society (BAS) reported. If the gargantuan berg becomes grounded near South Georgia island (a British overseas territory and one of the South Sandwich Islands), it could crush animals and block off […]

Antarctic ozone hole is one of the largest and deepest in recent years

The 2020 ozone hole is also one of the deepest. Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole has reached its maximum depth with a peak of around 100 DU on 2 October. Credit: contains modified Copernicus Sentinel data (2020), processed by DLR/BIRA/ESA Measurements from the Copernicus Sentinel-5P satellite show that […]
