Until now, it's been a common belief that the packed sea ice of the Southern Ocean blocked all light from reaching the sea beneath, preventing phytoplankton—tiny algae that are the base of aquatic food webs—from growing ...

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey ...
