Been seeing this pop up in my feeds lately, so watched a couple of vids. Fascinating. There are these metallic nodules that are believed to have been formed by precipitation of naturally occurring metals and minerals, and have fallen to the ocean floor in vast numbers. Composed mostly of manganese, cobalt and nickel, which makes them a perfect mining candidate for rare metals. But as it turns out, these nuggets have a natural electrical potential of just under 1volt, and have been shown to produce oxygen thru electrolysis. It's believed now that the presence of this oxygen contributes the the existence of entire ecosystems at great depths. So... no mining.
Here's a pretty decent explanation.
