Last Years Gulf Oil Spill May Be Contributing to Marine Mammal Deaths
“Mar 18, 2011 – Scientists investigate the cause of nearly 90 bottlenose dolphins in 2011
Though talk of the April, 2010 oil spill has lessened, the repercussions continue to surface. After an estimated 206 million gallons of oil spewed into the gulf nearly a year ago, the damage was inevitable. Despite the decrease in oil spill coverage, the bottlenose dolphin has recently been thrust into the oil spill spotlight due to an alarming study. So far this year 87 dead dolphins have washed up along the shorelines of the Gulf Coast; half of these deaths belong to premature, aborted, or stillborn dolphins. This number is alarming in itself, but it is especially alarming since it is 12 times higher than typical numbers at this time of year.
Experts are performing investigations to determine if the deaths are linked to the massive oil spill, the unusually cold winter, or some other cause yet to be discovered. Both the oil spill and the chemicals used to fight it and the cold winter can create a cumulative negative effect. Animals’ immune systems are weakened by chemical exposure thus decreasing their ability to adapt to cold weather. This combination can lead to an increase in infections that potentially lead to death.” Read more.
