Scientists Discover Huge Freshwater Reserves Beneath the Ocean

An anonymous reader writes "Scientists have discovered huge freshwater reserves beneath the seabed on continental shelves off the coast of Australia, North America, China and South Africa. 'The volume of this water resource is a hundred times greater than the amount we've extracted from the Earth's sub-surface in the past century since 1900. Fresh water on our planet is increasingly under stress and strain so the discovery of significant new stores off the coast is very exciting. It means that more options can be considered to help reduce the impact of droughts and continental water shortages' says Dr Vincent Post of the National Centre for Groundwater Research and Training (NCGRT) and the School of the Environment at Flinders University."

    Presumably this water will need to be accessed via drilling and pumping the water. Imagine the horrors if there were a water spill, contaminating all that ocean water with its freshness!

      Yeah, I worry about the same thing. Pumping up water from that depth has to be a bit of a challenge and use energy (though there are temperature gradients they could borrow to assist). Still, you also have the problem that after you remove a lot of fresh water -- that creates a new chamber that sea water could flood and contaminate.

      And what happens when you cause a landslide or underwater quake if you displace a LOT OF water? We've had sink-holes and land drop from removal of groundwater -- if the chamber is 100 times larger and the pressure 1000 times more, well, how bad does it get before the problem shows up?

      I'm not paranoid of the future, but our system currently is unable to change course if a profit is involved. We as a society in the USA can no longer expect that if something were to cause massive damage -- you for instance "fracking" natural gas MIGHT poison fresh water and cause small earthquakes (and well, it does in fact do that) -- but you wouldn't have the news really report it and you wouldn't have the FDA shut them down because someone would just secure a nice consulting job for when they left government service and Congress would get some campaign donations and do nothing and the media wouldn't report that because they'd get some advertising dollars featuring Deer sipping from ponds over a pump.

      Did I mention a broken system that cannot correct errors? I'm waiting for someone to pay me to blog happy things about Deer sipping from ponds over a pump -- I've seen them myself and people who don't like Frakking / Deep See fresh water are Hippie Commie tree huggers who hurt our economy!

    Before we try and get and that additional freshwater - has anyone found another possible _deposit_ location for all the rubbish and toxic waste we're producing? ...even if we would get at that water, it would only be a stop-gap -- right now, most seem to think that there will always be some new source of whatever resource we need to keep our "unsustainable" pace going...

    It's the same about what people say that the shale oil will give the US enough oil for 100 years -- it's _maybe_ 100 years _at the current pace of consumption. But if there is a 100 years worth of more energy - why even _try_ and save? Why not even indulge in even more energy-intensive enterprises?

    The same goes for finding huge amounts of new fresh-water - we'll just find ways to consume it even faster, instead of trying to focus on limiting the damage we do to the planet, and treating any additional resources as 'emergency rations' that we won't touch unless there is no other way.

      Well, there is the ground. That's where we put most of our rubbish and toxic waste. It works pretty well despite the complaints to the contrary.

      But if there is a 100 years worth of more energy - why even _try_ and save? Why not even indulge in even more energy-intensive enterprises?

      Because the cost is greater than the benefit. Sometimes it actually is worth conserving cheap energy.

      What's the point of this "focus"? The planet isn't that damaged. The resources in question aren't that depleted.

      But what I find fundamentally frivolous about this whole story is that apparently they've discovered a year's worth of rainfall (which is also in the neighborhood of half a million cubic kilometers). Freshwater is not a resource we're running out of. It's merely poorly distributed compared to who wants to use it.

      There is no logic in ensuring adequate resources for future generations. If I'm not alive to benefit, it doesn't matter what happens after I die. If you are an atheist, or otherwise do not believe in an after-life of any kind, this is even more true.

    As they pump the fossil water of deep aquifers in the desert, the dwells all around get dry or have now a much lower water level.

    Firstly, most of those desalination plants are already built, and second, I really doubt that getting to this water is simply a matter of "a few more pipes".
