Can undersea oil rigs become homes?
US Bureau of Ocean Energy Management
In coming decades many oil and gas platforms will have to be retired. Rather than being dismantled, they could be given a new lease of life as artificial reefs, helping industry and the environment.

How will climate change affect life in the oceans? New research shows that the answer is likely good and bad.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.

Spreading fishing pressure evenly across whole marine ecosystems sounds like a great idea. But there’s a hitch – we can’t technologically do it, and even if we could, it would be expensive.
Give up, brain coral, we have you surrounded.

With their natural predators removed, sponges are free to take over coral reefs.
Rhinos and blue whales get all the attention, but scallops are worth conserving too.
