After the spill: Mystery of the vanishing Gulf of Mexico turtles
After the spill: Mystery of the vanishing Gulf of Mexico turtles

There's something amiss with iconic marine animals in the Gulf of Mexico: sea-turtle populations are in retreat, dolphins are in poor shape and whales are avoiding their usual hunting grounds.
Such long-term effects seem to linger five years on from the largest oil spill in US history, which followed the explosion of the Deepwater Horizon rig on 20 April 2010, killing 11 workers and wreaking havoc on the region's wildlife.
Following the spill in the north of the Gulf of Mexico, there was a reverse in a sustained two-decade recovery of the world's most endangered sea turtle the Kemp's ridley, which neared extinction in the 1980s.
To what extent the oil disaster is to blame is still under debate, but the matter is shrouded in mystery partly because ongoing litigation over compensation means that few scientists are prepared to discuss their data publicly.
