WA oil spill map

The old shelf edge at around 150m depth is thought to be a major migration pathway.
There's high cetacean/whales and dolphin biodiversity to the south of Scott and Ashmore Reefs.
The surrounding area and the area to the north are combination of halimeda beds (which are a globally rare and unique conservation feature), coral reefs and upwelling from the trench creates an area of very high biodiversity that is thought to be an important site for cetaceans.
The red dot is the three well heads in the Montara Field
The black around the red dot is the boundary of the lease. The black diagonal lines in a circle are an arbitrary indication of the location – it does not relate directly to the extent of the spill.
The area around Ashmore reef has the highest diversity of sea snakes in the world. And they have to come up to the surface breath.
It’s also likely that there'll be a lot of baby turtles in the water up there at this time of year.
There's also an important geological formation – pinnacles - very close to the drill heads which are likely to be significant habitats.
