On my second attempt to spot whale sharks yesterday, I flew with the effervescent Bonny Schumaker, whose organization On Wings of Care helps protect wildlife and their habitats by helping with search, rescue, rehabilitation and scientific research. Samantha Whitcraft of the non-profit Oceanic Defense also joined us for the flight. We took off from New Orleans and flew about 50 miles south over the Gulf.

Bonny and her 4-seater plane, whom she lovingly refers to as “Bessie,” have years of experience spotting wildlife.  Unfortunately, despite Bonny and Bessie’s best efforts, the conditions yesterday were simply not ideal for finding marine life.

A recent study conducted at the University of Hawaii provides “sound” evidence that sonar induces temporary deafness in bottlenose dolphins. Many have long blamed man-made noise -- mainly sonar used by the navy -- for mass strandings of whale and dolphin species. Although this study does not provide concrete proof that submarine and warship sonar activity is causing strandings, it does prove definitively that sonar activity can affect cetaceans if they are close enough to the source and exposed over a prolonged period of time. Whales and dolphins use sound for navigation and temporary deafness can leave them disoriented. They are traveling over very large distances and cannot afford to lose their sense of direction. If they were to accidentally swim into a shallow area or be washed ashore, they could rapidly become dehydrated and die.
