Deadly Ocean Ice Tornado
Fans of the BBC’s Frozen Planet were treated to the first ever footage of a brinicle, a deadly finger of ice that kills everything in its path. Starfish and sea-urchins shrivel up and die, encased in a “tomb of ice” as the frozen tornado whirls its destructive path to the sea floor. The extremely salty ‘brinicle’ is not quite a solid icicle. The sea water is only forming a frozen ‘sheath’ around the cold saline, rather than freezing all the way through. Dr Mark Brandon, a polar oceanographer, described it as “a seawater-soaked sponge with a tiny network of brine channels within it.”
