The Deepwater Horizon oil spill will forever be a part of history, and has recently been a major driver for a change of protocol and regulation. One aspect of this disaster that is a direct consequence is how marine life has been impacted since April 20th, 2010.
Marine mammals have been greatly affected by the spill and populations may never fully recover. The three main species of marine mammals affected are already vulnerable populations. They are bottlenose dolphins, sperm whales, and Byrd’s whales. The physical damage of these species is critical, as the spill has caused oiling and inhalation of toxic fumes, but there is an equally critical and perhaps less known impact. The spill happened during the reproductive cycle for bottlenose dolphins, which will likely have a significant impact on the population. Many were found dead and many more were stranded and stillborn or neonates. However, this has not been officially linked to the spill even though many were covered in oil. Even a small number of calf deaths has a significant effect on the dolphin population. This holds true because the dolphins have made homes in many isolated areas of the Gulf. The effects on sperm and Byrd’s whales are not as known at this point, but with both species being endangered, the oil and toxics left behind cannot be good for the population.
