Decompression sickness (DCS) describes a condition arising from dissolved gases coming out of solution to form bubbles inside the body upon depressurization. So how do marine mammals, whose very survival depends on regular diving, manage to avoid DCS? Do they, indeed, avoid it? In April 2010, the Woods Hole Oceanographic Institution’s Marine Mammal Center (MMC) invited the world’s experts in human diving and marine-mammal diving physiology to convene for a three-day workshop to discuss the issue of how marine mammals manage gas under pressure. Twenty-eight researchers discussed and debated the current state of knowledge on diving marine mammal gas kinetics—the rates of the change in the concentration of gases in their bodies. "Until recently the dogma was that marine mammals have anatomical and physiological and behavioral adaptations to make the bends not a problem," said...
