Models that predict sea-level rise are typically built around the assumption that ice is melting from the world's largest ice fields in Antarctica and Greenland at a consistent rate.
Two earthquakes measuring 7.0 and 5.9 on the Richter scale jolted Chile's Magallanes and Antarctica region, with no reported casualties or damages, but authorities issued a tsunami warning after the first temblor.
Chilean authorities announced that at least 58 people that were at two military bases in Antarctica or on a navy ship that went to the continent tested positive for the new coronavirus.
Researchers have spotted patches of penguin poop in new high-resolution satellite images of Antarctica. This discovery has revealed the presence of small emperor penguin colonies that were previously overlooked.
Scientists have discovered an active methane leak in the seabed of Antarctica. The southernmost continent contains as much as a quarter of Earth's marine methane and now this leak from the sea bed prompts major concern about the impact on the global climate crisis.
Recent pictures of Antarctica would confuse anyone with the South American Prairie Grassland as the snow land has turned green. However, this phenomenon is not because of some goniochromism effect.
An astounding set of images that shows Antarctica snow turning blood red is going viral. The said pictures are taken near a former British research station.
Gory images of blood-red ice in Antarctica shook the scientists at Ukraine's Vernadsky Research Base in Antarctica. Marine ecologist Andrey Zotov from the National Academy of Sciences of Ukraine, captured these images while conducting research at the Antarctic station.
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of 200 mm (7.9 in) along the coast and far less inland
It would not be correct to say ice melt has not taken place before in Antarctica, NASA said. Satellite images, often partially obscured by clouds, show periodic melt since it was first visible in Landsat imagery in January 1973.
Canada, Greenland, Finland, Antarctic are among the coldest places on Earth. While Drass and Leh in India experience bone-chilling winters with temperatures dropping to as low as -50 degrees Celcius, there are other countries that witness brutal winters. Have a look at top 10 coldest places on Earth.
Developed by the scientists of the BedMachine project, the latest topographical map of Antarctica is believed to reveal the mountains, valleys, and canyons hidden under Antarctica's ice with high precision.
The plane took off at 4:55 p.m. from the southern city of Punta Arenas, which is more than 3,000 kilometers (1,860 miles) from the capital of Santiago. Contact was lost at 6:13 p.m., a statement said.
The study, published in the journal Nature Communications, shows that sea levels rose up to three metres per century, largely driven by ice loss in the Antarctic ice sheet.
