   Our oceans face a new threat: big mining companies want to chew up the ocean floor, destroying fragile ecosystems in the process. Join me in demanding that Canada stop deep sea mining before it’s too late.

   Thanks!

     I agree with this, the seabed is just as much part of the ecosystem as everything else, we keep discovering new life down on the seabed (so is it not as lifeless as we may have once thought) we need to protect it, not exploit for profit.

     I have shared on my blog, there should be a good few papers and journal articles looking at biodiversity in the deep ocean, let's share them too.

     So to this end, I have added some links to some resarch in to deep see biodiversity to my blog post, hope this helps.

     @zleap @nativeCalgarian It's theorised the nodules themselves are the source of oxygen that deep in the ocean. In that case mining them would eliminate even the possibility of life reasserting there, those tiny nodules are billions of years old.

     "While such geobatteries exist in nature, “getting enough voltage to be able to split water is very challenging,” "

     Given that seawater containts salts such as NaCl, KCl etc, does this make any difference or the concentration of these salts (which are IIRC Ionicly bonded) impact on how easily it is to split in Hydrogen and Oxygen, or does that then Produce H+ and OH- ions. I did read elsewhere, a while back that radioactive decay from various elements also plays a part in Production of Oxygen.

     So would this reaction help produce Oxygen from the OH- ions, in a similar way we see Radiation from the sun, hitting the atmosphere, causing O_2 to split then reform in to O_3.

     Seems there is a lot going on and complex, but potentially sensitive reactions taking place, sensitive in the sense that if we interfere with the ocean bed, it will really have a much larger impact.
