Marine Mammal Diving Pathophysiology

We have documented perimortem bubble formation in seals and dolphins drowned at depth in fishing gear (Veterinary Pathology 46: 536-547, 2009). We believe this indicates that such diving mammals are routinely supersaturated, and that they avoid clinical decompression sickness behaviorally. With support from the Office of Naval Research we are developed tools to study the underlying basis for these observations, by building a hyperbaric chamber compatible with a CT scanner, and by developing protocols for the use of Veterinary Ultrasound on live stranded marine mammals.
