Arr, the Mysteries of the Briny Deep

This Creeping Underwater Ice Tornado Kills Everything It Touches

Brinicles are columns of ice that form under very calm ocean conditions, when there’s a big differential between the water temperature (around -1.9C) and the air temperature about the sea ice (below -20C). The warmer sea flows up to the air, freezing into new ice. According to the BBC, “the salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.” This makes it fall down into the water, creating an ice plume that grows into the brinicle.

When it gets to the ground, it starts to expand, killing everything it touches. The whole process takes five to six hours, according to the team, which is surprisingly fast.
