A recent investigation published in the Proceedings of the National Academy of Sciences, spearheaded by a researcher from Nova Southeastern University, has revealed that populations of octopus, krill, squid, and shrimp in the deep northern region of the Gulf of Mexico have declined by 60 to 85 percent in the three and a half years following the Deepwater Horizon incident, with minimal signs of revival noted since then. The affected area, situated at depths ranging from approximately 650 feet to a mile, constitutes nearly 90 percent of the Gulf’s total volume. Researchers suggest that the oil spill is the most probable culprit, though this conclusion is drawn indirectly. Here are the findings from the survey.

00:00more than 15 years after the Deepwater Horizon oil spill.
00:03The Gulf of Mexico may still be paying a price.
00:06A new study in the Proceedings of the National Academy of Sciences,
00:10led by a professor at Nova Southeastern University in Florida,
00:14compared deep-sea surveys before and after the spill.
00:17The zone studied runs from about 650 feet down to roughly a mile,
00:21and it makes up about 90% of the Gulf's total volume.
00:25The result is shocking.
00:26Octopus, krill, squid, and shrimp fell by 60 to 85%
00:30in the three and a half years after the spill,
00:33with few signs of recovery since.
00:35Researchers called it the fastest and most severe decline ever reported
00:39for the largest ecosystem type on Earth.
00:42They ruled out temperature and oxygen,
00:44and say the spill is the most likely explanation,
00:47though that is inferred.
00:49One scientist said the Gulf has not recovered in over 15 years.
00:53Researchers also warn it could reduce how much carbon
00:55in the deep ocean stores.
