Sad news from the Gulf of Mexico: At least 32 dolphins in Barataria Bay, Louisiana, one of the hardest hit spots by the Deepwater Horizon oil spill, have been given physicals and are reported as severely ill according to NOAA officials.
The dolphins are reporting a range of symptoms from being underweight, anemic, low blood sugar and liver and lung disease. One of the studied dolphins has already been found dead.
There has been a large surge in dolphin deaths in the Northern Gulf of Mexico since the oil spill, especially newborn and young dolphins. In 2011 there were 159 strandings just in Louisiana, almost 8 times the historical average in previous years.
The numbers of dolphin carcasses found is likely only a fraction of the total amount of dolphins that were killed by the oil, and the true number is likely 50 times the total of 600 strandings since the spill, so more than 30,000 dolphin mortalities may have been caused by the spill already.
The spike in young dolphin deaths since the spill is extremely concerning, and showed biologists that the health of dolphin populations in the Northern Gulf had been compromised and many miscarriages may have occurred following contact with oil pollution.
