Using a small robotic sub, scientists from Columbia University have captured rare video of arctic jellyfish slithering along the bottom of the Chukchi Sea near Barrow Alaska. The footage came as a complete surprise to the researchers, who weren't expecting to see jellyfish during the Arctic winter.

Researchers working in the Barents Sea have discovered hundreds of craters on the Arctic Sea floor, some measuring over a kilometre in width. These craters, which date back to the end of the last Ice Age, were formed when large reserves of methane exploded in the wake of retreating ice sheets. Because methane is a potent greenhouse gas, this discovery is a potential warning of things to come in our warming world.
