Back in the 1960s-1980s there were hundreds of undersea habitats worldwide. Our three Sealab habitats were among the most advanced:

http://www.youtube.com/watch?v=JFBDs6yTkgM

They ranged from 200 to 600 feet deep, and the later two were guarded and supplied by a team of trained dolphins. It was secretly a test to see whether we could acclimate Navy Seals to those pressures so that we could retrieve Soviet warheads from downed submarines. According to declassified documents, this was successfully done at least once, which is part of why we still have an operational undersea lab today.

Saturation diving. Because of the gas mixtures used and the fact that there's no decompression required, human divers can stay out for up to 8 hours at a time on two tanks. Compare that to 30 minutes at the bottom, typical for surface dives, as the rest of the time is spend descending and slowly ascending.

The greatest discoveries in history were made because we had human beings living someplace fulltime, and while gathering samples, one of them happened to notice something unusual out of the corner of their eye, so they investigated.

Robots are efficient, but think of humans as incredible sophisticated, capable robots that simply need more support equipment. Sustaining them deep underwater is, as I've shown, not as much of a barrier as it used to be.

There's really not much to making a minisub. Plenty of individual tinkerers have done so and posted them on youtube. There's even an annual homemade minisub race. Pic related.

The push for electric cars will actually greatly help to reduce minisub costs, as the bulk of the price is the batteries.

So even with a hardsuit the maximum depth a human diver can attain is ~3000 feet.

With an AUV, the maximum attainable depth is the bottom of the ocean, anywhere in the ocean.

AUVs can stay out for half a year without needing a recharge. This one design might even allow them to use the ocean's thermal gradient to recharge, basically allowing them to operate forever, for the most part.

Teleoperated underwater robot bases could also allow for the "notice something out of the corner of eye" aspect. Heck if we could put something as simple as a webcam at a hydrothermal vent, we'd learn quite a bit.

Anyway, seems like the thread's sinking (lolol) so I'll wrap it up.

The fact that the international space station is bigger ten times over than our nation's only undersea science outpost is sickening.

I support space exploration. But realistically we get more bang for our buck exploring the sea. Sink a habitat off the great barrier reef and I can guarantee new species will be discovered every week, whereas we're still waiting on the discovery of even a single extraterrestrial microbe after hundreds of billions of dollars of investment into the space program.

We need a colony on the moon and mars for the simple reason that we will likely be wiped out by an asteroid one of these centuries. It's happened with some regularity in the past and it's bound to happen again.

However an ocean floor colony could withstand nuclear war, plagues, runaway warming and just about any other catastrophe short of planetary annihilation. It offers access to methane hydrates, to deep sea manganese nodules and other deposits of rare earth minerals crucial for the production of cleaner fuels, electric cars, wind turbines and solar panels.

Why does that matter? Because China, the world's source for rare earth minerals, has just cut off our supply: http://oilandglory.foreignpolicy.com/posts/2010/10/19/is_it_a_clean_energy_trade_war_yet_china_cuts_
off_rare_earth_shipments_to_the_us

and while environmentalists worry about the pollution, plans for deep sea mining of rare earth minerals so as to circumvent the Chinese monopoly have already begun: http://www.independent.co.uk/environment/nature/deepsea-mining-adds-to-fears-of-marine-pollution-201
6292.html

The resources we need to build a better tomorrow and to meet our growing need for biomass and electricity can be found in the sea. One day we will send refinery ships to the asteroids, and mine the sky. But until then, we will send men into the deep, and mine the sea floor.

Right, I know that. But as I said they can do a crude, imprecise and specialized sort of mining. They are usable now because the seafloor is replete with easily accessible exposed mineral veins/nodules. That won't always be the case and for some types of mining, we will need human beings.

>>1948421
bullshit. if you're doing ANY kind of hi resolution mapping or photo collection, there is no fucking way an AUV can run for 6 months...it'll run out of data storage and battery WAY before then. the way we run AUV cruises now is to deploy them for a few days while we do other stuff, then collect the AUV, check out the hi-res maps and decide where to go next...especially helpful in mapping recent eruptions at the mid-ocean ridge. HOWEVER, AUVs are not reliable enough yet to just let them go for as long as you suggest. we're just not there yet.

as to why we need HOVs (human occupied vehicles)...there is no replacement for the human experience of doing science in the deep sea. you need to have a human brain down there for interpretation and quick changes to your dive plan. i work at 2400-2700m below the surface and it's a hell of a lot different being in the Alvin (I get more out of looking out the porthole) than using the JASON ROV (where I'm just seeing through a camera).

These are basically the same conclusions I came to. Additionally while I desperately want to see larger sea colonies built, and they may be, it won't be for science. I can think of no research project that necessitates the physical presence of more than six aquanauts, which is likely why every habitat from Sealab I all the way up to Aquarius has had room for six.

The future of undersea exploration is most likely robots teleoperated from modest undersea labs. The robots do most of the surveying and sample collection, while humans experiment on what they bring back and physically go out to investigate anything interesting the robots spotted while out and about that they're not equipped to deal with.

You're still dragging around a tether, but now you're using solar/battery power.

>>Also how's you're underwater base going to stay in touch with the outside world? Will it have internet?

Sure, via a tethered buoy it can send up for transmission.


If you were to build a few thousands wireless repeaters, each a self contained ad-hoc node powered by a zinc fuel cell or some other long lived energy source, you could simply lower a FiOS tether from a ship with a transceiver on the end of it. It'd establish a connection with the nearest node and your ROV would now be able to roam, tether-free, within the wireless coverage of the node network.

However, at the end of the day you still have to recover the ROV, haul up the tether and go ashore. Operating from the surface actually works out to be costlier in the long term than having an undersea habitat, which is why we still operate one for reef study.

also....unless you're implying that satellites can 'see' through water (which they can't), your AUV has to surface every time it wants to upload. and the satellite would have to be in range. current battery technology is not good enough yet to allow this on a repeated basis!!!! that AUV that could use the thermal gradient to recharge is IN DEVELOPMENT.
