Brinicle, Underwater Icicle, Captured Forming By Time-Lapse Camera
New video has been released that shows the formation of a brinicle on the ocean floor. Essentially an underwater icicle, the brinicle, or “finger of death,” freezes everything in its path.
Hugh Miller and Doug Anderson filmed the stunning time-lapse clip below, which is apparently the first of its kind. Shot for the BBC’s “Frozen Planet,” the clip was recorded using a special time-lapse camera that caught the brinicle’s entire formation process.
What’s really going on here is the freezing of warmer waters as sub-zero brine slowly sinks to the ocean floor.
