Called a “Brinicle” it’s caused by cold, sinking brine, which is more dense than the rest of the sea water. It forms a brinicle as it contacts warmer water below the surface.

Mr Miller set up the rig of timelapse equipment to capture the growing brinicle under the ice at Little Razorback Island, near Antarctica’s Ross Archipelago flash freezing the slow moving starfish in its path.
