The Deepwater Horizon oil spill, which occurred in the Gulf of Mexico in 2010, had a devastating impact on marine life in the region, including dolphins. A large number of dolphins died as a result of the spill, and many others were left with long-term health problems.
Key Facts
- A total of 1,141 dolphins died from March 2010 through July 2014 as a result of the Deepwater Horizon oil spill.
- The dolphin deaths were part of the largest and longest-lasting cetacean mortality event ever recorded for the northern Gulf of Mexico.
- Dead bottlenose dolphins stranded in the northern Gulf of Mexico after the spill showed lung and adrenal gland injuries consistent with petroleum exposure.
- The new evidence suggests a strong link between the dolphin deaths and the environmental disaster caused by the Deepwater Horizon oil spill.
Dolphin Mortality
The total number of dolphins that died as a result of the Deepwater Horizon oil spill is estimated to be 1,141. This number is based on data collected from stranded dolphins and from surveys of live dolphins in the affected area. The dolphin deaths were part of the largest and longest-lasting cetacean mortality event ever recorded for the northern Gulf of Mexico.
Causes of Death
The cause of death for many of the dolphins that died as a result of the Deepwater Horizon oil spill was determined to be lung and adrenal gland injuries consistent with petroleum exposure. These injuries are likely to have been caused by the dolphins inhaling or ingesting oil or oil-contaminated water.
Long-Term Health Effects
In addition to the dolphins that died as a result of the Deepwater Horizon oil spill, many others were left with long-term health problems. These problems included respiratory problems, reproductive problems, and immune system problems. Some of these dolphins may never fully recover from the effects of the oil spill.
Conclusion
The Deepwater Horizon oil spill had a devastating impact on dolphin populations in the Gulf of Mexico. A large number of dolphins died as a result of the spill, and many others were left with long-term health problems. The spill is a reminder of the importance of protecting our oceans from pollution and other human activities that can harm marine life.
