Polymetallic Nodules. Never heard of them? Well there are trillions of them on the deepest sea beds of our oceans. Mining companies want to scoop them all up for the valuable elements they contain, like manganese, cobalt and nickel. But new research has demonstrated that those metallic constituents are causing a reaction that creates oxygen in the total absence of sunlight or photosynthesis. So...is it really a good idea to remove them?

Dunno if the same thing, but I read back in the 60's they were thinking of mining nodules in the ocean floor, I think for manganese, but maybe molybdenum. It was gonna be cheap to collect them and the market was high.
Then they realised that if they went ahead the supply would quickly outstrip demand (like within months), the market would crash and cause chaos for decades.

I think someone had already posted the documentary about the oarfish, but here it is again. It's very interesting. A scientist in scuba gear was cleaning off equipment off the coast of France, and suddenly, there it was. I highly recommend a watch.
