Submarine sonars threatens Dolphin and Whale Survival

A new report brought out by the United Nations Environment Programme (UNEP) and the Convention on Migratory Species (CMS) says the use of powerful submarine sonar is harming the ability of some 71 types of cetaceans - whales, dolphins and porpoises - to communicate, navigate and hunt. These low frequency sounds travel vast distances, hundreds if not thousands of kilometres from the source. Species like the Beluga whale, Blanville's beaked whale and the Goosebeak whale are seriously at risk
