"Copley said that characterising the life at the world's hydrothermal vents was a race against time. "Earlier this year, China was granted a licence by the UN International Seabed Authority for exploratory mining at deep-sea vents on the southwest Indian ridge," he said. "The vent chimneys are very rich in copper, zinc, gold and uranium. But we have no idea what's actually living there."

In evolutionary terms, hydrothermal vents were like the islands of the ocean floor, he added. "Just like the 19th century naturalists used to go to the Galápagos and other islands to find species there that are different to elsewhere and then use that to understand patterns of dispersal of dispersal and evolution, we can use deep-sea vents to do the same things beneath the waves," he said.

"And we need to do that because the exploitation of the deep ocean is overtaking its exploration. We're fishing in deeper and deeper waters, oil and gas is moving into deeper waters and now there's mining starting to take place in deep waters. We need to understand how species disperse and evolve in the deep oceans if we're going to make responsible decisions about managing their resources."

They don't need to conflict. We must conduct a survey of deep sea vents. The species around most are likely to be nearly identical, with only a few really unusual oddball ecosystems worth investigating. Those can be declared off limits and the rest can be mined. Or, we levy a tax on deep sea mining and the proceeds go to new deep sea labs, robots and submersibles.

We need to start looking into asteroid mining seriously, for the sake of the environment.

Deep sea mineral harvesting is a fucking mess, it causes huge plumes of silt to cloud up the water and could devastate our already fucked sea friends. The short term gains aren't worth it, we need to pace ourselves!

Japan has also discovered a massive (100bn ton) vein of rare metals at the bottom of their sea. Fuckety fuck.

It's not especially messy to suction up rare earth mud, as Japan is planning on doing. It's using robots with bucket wheel excavators (like huge circular saws) to carve up deep sea vents that creates the plumes. The thing is we don't have robots dextrous enough to mine more precisely or carefully, the best we can do is have them shred the thermal vents using those huge circular cutting dealies.

If we could put human beings down there with powered mining tools we could extract minerals faster and more cleanly, possibly also preserving much of the vent ecosystem by carving around areas with no precious metals, leaving as much as possible for the remaining animals.

The problem is, robots are cheaper so that's how they'll do it unless environmental regulations force them to use human workers instead.

Get your facts straight (it's not a vein it's mud): Assuming an average REY content of 1,180 +/- 189 ppm and dry bulk density of 0:66 g cm^-3, the 10-m-thick bed of REY-rich mud in an area of 1 km^2 at Site 76, in the eastern South Pacific, has the potential to yield 9,110 +/- 1,460 tonnes of REY oxides (tREY-oxides), or one-fifteenth (one-eighteenth to one-thirteenth) of the global annual consumption of REY in 2010 (134,000 tREY-oxides). Similarly, assuming an average REY content of 640 +/- 102 ppm and dry bulk density of 0:477 g cm^-, the 70-m-thick REY-rich mud layer in an area of 1 km^2 at Site 1222 in the central North Pacific holds nearly 25,000 +/- 4,000 tREY-oxides; 5 km^2 (about 2:3 km x 2:3 km) of this material at Site 1222 could possibly supply the majority of current annual REY consumption in the world. Considering that the REY-rich mud shows a thick distribution at many sites throughout the eastern South and central North Pacific, the seafloor REY resource potentially could exceed the world's current land reserves of 110 +/- 106 tREY-oxides, although more detailed sampling and analysis are needed to properly evaluate this possibility. Irregular
bottom topography, local currents, and highly variable rates of
biogenous sedimentation together may produce major differences in the REY-rich mud thickness over relatively short distances, hence resource estimates for large regions cannot be made until more detailed data are available for areas lacking cores.

Also, the life at that depth is minimal - mine the fuck out of it and fuck China. Also, mine the moon for rare earths.

>> No.4221838


We are running out of easily accessible resources. The ocean floor contains a whole second planets worth. Concern for wildlife will not keep us away from those resources. We need them to continue modern technological civilization, especially post-oil. Without the metals we need for electric cars, wind turbines, solar panels and nuclear reactors, life will suddenly become extremely shitty as the wells run dry. We can strike some compromise to protect the deepsea ecosystem, but we literally must industrialize the seafloor to keep society running and to make progress towards cleaner, more efficient forms of energy possible. You would nee dto be suicidal or misanthropic to stand in the way of that.
