Drought-Related Algae, Oil Spill Blamed For Mysterious Deaths Of 123 Dolphins Off Texas Coast
By Associated Press – “HOUSTON — The deaths of more than 120 dolphins off the Texas coast has prompted a federal agency to declare the event ‘unusual’ and launch an investigation into whether they were related to a drought-related algae bloom or a more widespread mortality event that has plagued the northern Gulf of Mexico for two years.
The U.S. National Oceanic and Atmospheric Administration has called the stranding of 123 dolphins on Texas shores from November through March an ‘unusual mortality event,’ an official federal listing that allows the agency to access additional funds and set up a team of researchers.
All but four of the dolphins that washed up in Texas were dead, and the few that turned up alive died a short time later, said Blair Mase, the southeast marine mammal stranding network coordinator for NOAA Fisheries. What alarmed scientists though, was the age of the bottle-nosed dolphins that washed up — juveniles rather than the very young or elderly that normally would be found — and the fact that Texas had a years-worth of dead dolphins turn up in a five-month period.
The cause, however, may not be known for months, if at all, Mase said.
‘That’s what’s a little frustrating about this. It’s not like you see on TV, on CSI, you don’t get the answers quickly,’ she said. ‘It can take months and sometimes years.'” Read more.
Flashback: Gulf of Mexico: Thousands of Dolphins Dying in Massive Die-Off, Symptoms Consistent With Those Seen in Animals Exposed to Oil – “The dolphins in the Gulf of Mexico are in the midst of a massive die-off. The reasons why remain a complicated and mysterious mix of oil, bacteria and the unknown. Normally an average of 74 dolphins are stranded on the northern shore of the Gulf of Mexico each year, especially during the spring birthing season. But between February 2010 and April 1, 2012, 714 dolphins and other cetaceans have been reported as washed up on the coast from the Louisiana/Texas border through Franklin County, Fla., reported the National Oceanic and Atmospheric Administration. Ninety-five percent of the mammals were dead. Since many of the dead dolphins sink, decompose or are eaten by scavengers before washing up, NOAA believes that 714 may represent only a fraction of the actual death count.” Read more.
