CODE NAME: HABBAKUK

Text by Susan R. Eaton The Allies had a plan to crush Nazi aggression using gigantic iceberg aircraft carriers built in Canada’s north. Code named Habbakuk, the scheme was eventually torpedoed and the prototype vessel sank in a remote Rocky Mountain lake. Most shipwrecks are frozen in time, but the Habbakuk, the 1:50 scale prototype DEHYDRATION AND DIVING Dehydration reduces the circulating blood volume, the perfusion (blood flow) of tissues, and therefore the elimination of inert gas. If the elimination of inert gas is reduced, the diver will surface with more inert gas in the body and thus have an increased risk of developing DCS. Dehydration also increases the viscosity (thickness/stickiness

OXYGEN TOXICITY

By Divers Alert Network Oxygen toxicity is a serious condition, and many divers struggle to understand it.

DEEPER DOCUMENTARY REVIEW Most divers won’t descend below 130 feet (40m) though diving deeper is very appealing to many of us, myself included. It opens up new territory: deeper wrecks, caves, walls, blue holes, and for others it’s a way to conduct research or make a living. But 10 THINGS TO KNOW BEFORE BUYING A REBREATHER Words and Photography by Jill Heinerth Rebreathers offer an entirely new way to enjoy the underwater world. Whether it is the technology that attracts you or the potential to swim free without making bubbles, the decision to enter the domain of rebreather diving is a significant one.
