A noisy technology that blasts high-frequency sounds below water to map the ocean for oil probably caused the deaths of 75 melon-headed whales off Madagascar, experts said Thursday. An independent panel of scientists found that sonar surveying by ExxonMobil in late May 2008 led to the sudden displacement of around 100 whales, of which at least three-quarters died.
