A Glimpse Under the Ice

Have you ever wondered what it looks like under the ice, looking torward the surface...? 

Author John Heine is all too familiar with the view from under the ice. 

Pictured below, John is testing the Poseidon Se7en rebreather under the ice in Antarctica.

John serves as the National Science Foundation, U.S. Antarctic Program Diving Safety Officer and he recently completed a research project evaluating the use of rebreathers in Antarctica for the scientific diving program.

His diving has taken him to many areas of the world, including both poles and tropical areas in between. 

He spent fifteen seasons in the Antarctic doing research dives through ice that was ten feet thick, in water temperatures of 28.6ºF, and air temperatures as low as -60ºF . . . not for the faint-hearted!

As you can probably surmise (or as you may have experienced yourself), cold water and ice diving can be extremely challenging and requires a lot of planning, preparation, training, and safety. 

John literally "wrote the book" on cold water and ice diving. His book, Cold Water Diving: A Guide to Ice Diving  covers cold water and ice-diving environments; training; equipment; thermal protection; evaluating, preparing, and planning dives; and safety and emergency procedures.
