You might think you don’t see anything good when diving in cold water, but video explorers from the Discovery Channel captured incredible video under the Antarctic ice. The Discovery Channel’s series Frozen Planet premieres March 18.

From Fox News…

Called a brinicle (or brine icicle), cameramen Hugh Miller and Doug Anderson used a time-lapse camera to capture this awe-inspiring event beneath the Antarctic ice shelf for the upcoming Discovery Channel special series, Frozen Planet.

“We were just blown away by how beautiful they were,” producer Kathryn Jeffs told FoxNews.com. Jeffs was in Antarctica with Miller and Anderson to capture the unique event. “We were exceptionally excited and we knew we had something that had never been filmed before, never been seen before. No one has really seen the formation of a brinicle.”

This magnificent yet terrifying phenomenon is caused by brine, or naturally occurring salt water, which tends to be denser than the surrounding seawater and has a lower freezing point. When super cold brine trickles down, the warmer seawater surrounds the cyclone with a brittle layer of ice.
