This icicle is caused by sinking brine, which becomes concentrated with salt at the surface. It's super-salinity both allows it to become colder than ice, and sink, as it's denser than sea water.

It was filmed by BBC filmmakers under the ice at Little Razorback Island, near Antarctica's Ross Archipelago. [Via BBC]
