Cold weather, not oil spill, seems responsible for the recent spate of baby-dolphin deaths along the Gulf of Mexico coast, according to researchers at the Dauphin Island Sea Lab. They point to an apparent correlation between large pulses of chilly water that flowed into Mobile Bay, Alabama, during January and February this year and the subsequent discovery of dozens of stillborn dolphin calves in area waters. Data on water temperature and river flows shows periods in each month when bay waters dipped into the 40s for days at a time. Shortly after bay temperatures dropped precipitously, dead stillborn dolphins began washing ashore in Alabama.
