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.
