Scientists split on cause of dolphin deaths in Gulf

But Monty Graham, a scientist at a research lab in Alabama, blames cold ocean temperatures.

“He noted that water temperatures abruptly plunged from the upper 50s into the 40s off Dauphin Island in January, just before the first two stillborn calves found there were recovered,” Reuters said. “He said a second wave of dolphin carcasses washed ashore after temperatures dipped again.”

At least 82 dolphins have been found dead along the Gulf coast.
