World’s largest fish breeding grounds found under the Antarctic ice | Science

The most extensive and densely populated breeding colony of fish anywhere lurks deep underneath the ice of the Weddell Sea, scientists aboard an Antarctic research cruise have discovered. The 240 square kilometers of regularly spaced icefish nests, east of the Antarctic Peninsula, has astonished marine ecologists. “We had no idea that it would be just … Read more

What Antarctica’s ‘Doomsday’ Glacier Could Mean For The World

The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier hemorrhages more and more ice.   Adding 65cm to global sea levels would be coastline-changing amounts. For context, … Read more

Shockingly Abundant Life Found Thriving in Darkness Under an Antarctic Ice Shelf

Deep under the ice of Antarctica’s Ekström Ice Shelf there is nothing but complete darkness. Well, complete darkness and a thriving ecosystem that’s existed for thousands of years, according to a new paper by researchers from the UK and Germany.   “This discovery of so much life living in these extreme conditions is a complete … Read more

Ice shelf holding back keystone Antarctic glacier within years of failure | Science

An alarming crackup has begun at the foot of Antarctica’s vulnerable Thwaites Glacier, whose meltwater is already responsible for about 4% of global sea-level rise. An ice sheet the size of Florida, Thwaites ends its slide into the ocean as a floating ledge of ice 45 kilometers wide. But now this ice shelf, riven by … Read more

Bounteous harvest in Antarctic greenhouse may bode well for Mars colonization

A greenhouse in Antarctica testing technologies that could one day grow food for Mars colonists has produced an abundant harvest of greens, vegetables and spices completely without soil and natural light, showing promise for future space missions. The greenhouse, called EDEN ISS, is operated by the German Aerospace Center (known by its German acronym, DLR) … Read more
