In a presentation at the University of Hawaii at Manoa, Marsha L. Green, founder and president of the Ocean Mammal Institute, warned that low frequency sonar, used by the Navy to detect submarines, is dangerous to marine mammals.
Green claimed sonar is so loud it has the power to injure, deafen and kill marine mammals, as well as disrupt their behaviors. She cited mass stranding, abandonment of calves and whales' cell membrane ruptures as examples of the dangers of sonar.
Currently, the military is restricted to using the low frequency active sonar technology in 10 percent of the world oceans until the summer of 2003, as a result of a lawsuit filed by the Natural Resources Defense Council.
According to Green, the military has other options available to detect silent submarines that do not harm marine life.
She urged the audience of UH law students and faculty to write to their senators regarding the Readiness and Range Preservation Initiative, a bill that would allow the military to bypass several animal and environmental protection acts.
