Greenland’s Ice Cap The Greenland ice cap has an estimated volume of 1.7 million km3 with numerous glaciers that extend from the ice cap out to the Davis Strait. The most well-known of these is the Ilulissat Glacier. It is one of the fastest and most active glaciers in the world, creating dramatic and breath-taking scenery of ice and sea. Producing 10% of all Greenland’s ice fields, this glacier represents roughly 35 billion tons of ice a year. The ice fields of Greenland’s glaciers are products of the ice cap, formed form fresh water which has fallen as snow over the…

Regulators and Cold Water Regulator free-flows are one of the greatest hazards when diving under ice or in very cold water (less than 4°C). The condition is caused by the sudden drop in pressure as air passes from the cylinder through the first stage. When high pressure air passes through the first stage, it hyper-cools the metal moving parts. In a piston reg, small ice crystals can block the piston open, causing more air flow and trapping the piston open, creating a vicious feedback loop of more air, more ice and a runaway free flow. The air pressure overwhelms the downstream…
