A large number of scientific discoveries emerged from Earth's most southerly continent this year. Here are some of our favorites.
Because of its remoteness and forbidding climate, there is still a treasure trove of weird and wonderful oddities beneath the ice and waves just waiting to be discovered. And in 2022, scientists hit the jackpot. From secret ecosystems and ancient DNA to logic-defying blooms and creepy fish nests, here are our top Antarctica stories from this year.
Resting at a depth of around 24,400 feet below the sea surface, or 17 Empire State Buildings stacked top to bottom, the Factorian Deep was only discovered in 2019. But, until now, researchers had no idea how it fit together with the surrounding seafloor. Scientists had previously assumed that there was not enough light in the water below polar sea ice for phytoplankton to produce enough energy to survive. But the new studies revealed that the algae can thrive with as little as 1% of the light available at the surface.
Scientists aren’t certain which species the oldest DNA samples belong to, but the most recent samples likely originate from a group of phytoplankton known as diatoms. The diatoms date back to an ancient period of global warming and could provide clues as to how Antarctica's marine ecosystems will respond to human-caused climate change.
Enormous underground river discovered Researchers discovered a massive underground river that flows beneath four separate ice masses using ice-penetrating radar mounted on aircraft. Normally, when icebergs drift into the Drake Passage they are quickly dragged eastward by strong ocean currents, before being whipped northward into warmer waters, where they completely melt soon after.Read more: World’s largest iceberg is getting swept away from Antarctica to its doom, satellite image shows
