Excerpts;

A new international study has measured the effect of loud sounds on migrating humpback whales as concern grows as oceans become noisier. Scientists have said one of the main sources of ocean noise was oil and gas exploration, due to geologists firing off loud acoustic air guns to probe the structure of the ocean floor in search of fossil fuels…

Accoustic Pollution and Marine Mammals, Nature
In the Canary Islands, 14 beaked whales washed ashore bleeding from the ears. All eventually died. A post-mortem examination revealed that the whales showed signs of decompression sickness (what scuba divers call “the bends”). Decompression sickness can occur when a mammal swims to the ocean’s surface too quickly, and the change in pressure produces lethal nitrogen gas bubbles that clog its blood vessels. Evidence of acute decompression sickness indicates unusual behavior. Over the past 40 years, cumulative research across the globe has revealed a coincidence between naval sonar testing events and acute decompression sickness in beached marine mammals…
