Deep sea mining 'gold rush' moves closer

 
Nautilus operation The idea of exploiting precious metals on the ocean floor has been considered for decades

The prospect of a deep sea "gold rush" opening a controversial new frontier for mining on the ocean floor has moved a step closer.

The United Nations has published its first plan for managing the extraction of so-called "nodules" - small mineral-rich rocks - from the seabed.

A technical study was carried out by the UN's International Seabed Authority - the body overseeing deep sea mining.

It says companies could apply for licences from as soon as 2016.

The idea of exploiting the gold, copper, manganese, cobalt and other metals of the ocean floor has been considered for decades but only recently became feasible with high commodity prices and new technology.

Conservation experts have long warned that mining the seabed will be highly destructive and could have disastrous long-term consequences for marine life.

The ISA study itself recognizes that mining will cause "inevitable environmental damage".

But the report comes amid what a spokesman describes as "an unprecedented surge" of interest from state-owned and private mining companies.

Sharing the proceeds

The number of licences issued to prospect for minerals now stands at 17 with another seven due to be granted and more are likely to follow. They cover vast areas of the Pacific, Atlantic and Indian Oceans.

One of the most recent to be granted was to UK Seabed Resources, a subsidiary of the British arm of Lockheed Martin, the American defence giant.

Under the UN Convention on the Law of the Sea, the ISA was set up to encourage and manage seabed mining for the wider benefit of humanity - with a share of any profits going to developing countries.

Now the ISA is taking the significant step of moving from simply handling bids for mineral exploration to considering how to license the first real mining operations and how to share the proceeds.

The ISA's legal counsel, Michael Lodge, told the BBC: "We are at the threshold of a new era of deep seabed mining."

The lure is obvious. An assessment of the eastern Pacific - a five million sq km area known as the Clarion-Clipperton Zone - concluded that more than 27 billion tonnes of nodules could be lying on the sand.

Those rocks would contain a staggering seven billion tonnes of manganese, 340 million tonnes of nickel, 290 million tonnes of copper and 78 million tonnes of cobalt - although it's not known how much of this is accessible.

Right incentives

According to the planning study, the ISA faces the challenge of trying to ensure that nodule mining's benefits will reach beyond the companies themselves while also fostering commercially viable operations.

The plan relies on providing operators with the right incentives to risk what would be expensive investments without losing the chance for developing countries to get a slice of the proceeds.

But the ISA identifies what it calls a "Catch-22" in this brand new industry as it tries to assess which companies are skilled enough to carry out the work.

"Competence cannot be gained," it says, "without actual mining at a commercial scale, but at the same time mining should not be allowed without prior demonstration of competence."

A key factor in the ISA's thinking is the need for environmental safeguards, so the document calls for monitoring of the seabed during any mining operation - though critics wonder if activity in the ocean depths can be policed.

The prospect of deep sea mining has already sparked a vigorous debate among marine scientists, as I found earlier this year on a visit to the British research ship, James Cook, exploring the hydrothermal vents of the Cayman Trough.

The expedition's chief scientist, Dr Jon Copley, a biologist from the University of Southampton, urged caution.

"I don't think we own the deep ocean in the sense that we can do what we like with it," he said. "Instead we share responsibility for its stewardship.

"We don't have a good track record of achieving balance anywhere else - think of the buffalo and the rainforest - so the question is, can we get it right?"

Extinction risk

And Prof Paul Tyler, also a biologist, of the National Oceanography Centre, warned that unique species would be at risk.

"If you wipe out that area by mining, those animals have to do one of two things: they disperse and colonise another hydrothermal vent somewhere or they die.

"And what happens when they die is that the vent will become biologically extinct."

However, marine chemist Prof Rachel Mills, of the University of Southampton, called for a wider debate about mining generally on the grounds that we all use minerals and that mines on land are far larger than any would be on the seabed.

She has carried out research for Nautilus Minerals, a Canadian firm planning to mine hydrothermal vents off Papua New Guinea.

"Everything we are surrounded by, the way we live, relies on mineral resources and we don't often ask where they come from," she said.

"We need to ask whether there is sustainable mining on land and whether there is sustainable mining in the seas.

"I actually think it is the same moral questions we ask whether it's from the Andes or down in the Bismarck Sea."

This debate is set to intensify as the reality of the first mining operations comes closer.

    And when they overdo it, which they will, the gold price will drop, the whole operation going bankrupt.

    It will be a rush to get their first, coin it in before the speculation collapses, then certain individuals will scuttle off with a bag full of money?

    This isnt about mining for gold and diamonds for bling, it's about mining for rare earth metals that nearly everything these days contain, and that China has a huge monopoly on. And surely by 'licensing', it's implied that it means it will be regulated, controlled and sustainable. I agree that if you're going to protest, do so to make sure it's all of these things. It's a fact we need these metals

    I would like to know more about the possible ecological side-effects before making a judgement.

    If the mining process is literally digging/cutting the nodules away from completely isolated sites, not affecting the ecology apart from changing the sea landscape none of us will ever see, I don't see a problem. Especially if it means greater supply of increasingly rare minerals found on land.

    Love the rush to judgement without doing any research whatsoever. Anyone who lives in a house, uses electricity, drives a car, has healthcare (basically lives in the western world) needs to consider where the raw materials for everything they see or use around you comes from. Copper, cobalt, nickel, zinc, manganese-its not all about the elite hoarding gold. And whoever mentioned diamonds...PLEASE!

    This story would be more useful if the figures quoted on the number of tonnes of minerals available were in some form of context. Providing a figure of the global annual use of each mineral, or something similar, would provide a much better indication of just how large (or small) these potential resources are.

    With all the gold that is locked up in 'precious' and 'priceless' pieces of jewellery - such as those held by royal families and rulers around the world - why do we need more?

    Can't we just reuse these? Or are gems more important that the planet, it's ecosystems and its irreplaceable minerals and resources?

    We need to get our priorities straight - haven't the UN heard of natural wealth?

    Five million square miles of seabed, with the forthcoming potential to be turned into a undersea desert within which possibly nothing, will grow for another few more million years. Total marine devastation is a very strong forthcoming possibility. Both frightening and appalling.

    It's not going to work out very equitable for those of us not in a position to benefit from raping the sea floor.

    Still it's nice to know that those with the money will be able to make more of it.

    Let's just hope that all this activity doesn't have negative effects that affect us all.

    maybe this is some perverse plan to contain the water from the melting ice fields, by removing a few inches of material from the sea bed!

    There is no point in worrying ,the man with the money always wins..ruining the sea floor wont be a problem for Wall St. the next generation will watch 'Discovery" and marvel at man's ingenuity and courage...the price tag as always will come later.

    @16 Well thought out response.

    As you say progress is progress, well that would be the case except for the most ignored ´law of unforseen consequences` which often reults in progress being anything but.

    Example - Nuclear Power v Chernobyl. what should have been a great benefit turned into a threat through abuse and misuse.

    So as you so eloquently put it... go do one.

    Such a sad shame the UN seems so happy to sell out for a few short-term $$$. Rather than explore the oceans for life, they're happy to condone extinction and 'inevitable environmental damage' - incredibly awful, selfish and greedy behaviour.

    Diver, fisherman and trying to be more and more eco. We need metals but i wonder if perhaps we should exhaust global metal recycling before going anywhere like this. Im probably being naive. It wouldn't be the first time.

    Why - when it is gold being talked about - do people get uptight?

    Over fishing hardly gets a mention - and we are already taking millions of tons of oil and gas from under the sea bed..
