What happened to the massive underwater 'oil plume'?
Hollywood turns its hand to the worst environmental disaster in US history – from which the environment is strangely missing.
It took BP 87 days to cap the Gulf of Mexico spill.
BP's plans for the Bight say it would take 10 days to begin dispersing an oil spill at source, and 35 days for well-capping equipment to reach the site – making it likely that oil would hit the coast.
Overfishing can teach us valuable lessons about ecosystem resilience.
Large-scale natural experiments such as oil spills, tsunamis and climate change are things you wouldn't want to do on purpose. But that doesn't mean they're not scientifically useful experiments too.

Big oil companies are moving to exploit new resources such as the Arctic or the Great Australian Bight. But are they worth the risk?
The MV Shen Neng I spills oil onto the Great Barrier Reef in 2010. Large accidents are rare, but there is still very little monitoring of long-term chronic damage from shipping.
Port traffic near the Great Barrier Reef will more than double by 2025, as coal and other exports grow. While major incidents are rare, the chronic toll on the reef itself still remains largely unknown.
Uncertainty over seafood safety caused anxiety in coastal communities in the wake of the spill.
