‘Anti-Alberta’ inquiry points finger at media and environmentalists but finds no wrongdoing
The controversial and over-budget two-year probe, which has been criticized as a politically charged effort...
Until recently, the largest ecosystem on earth has stayed mostly beyond human reach.
But a new chapter in resource extraction could open up Earth’s most remote places to industrial development.
The deep sea, broadly considered the area of ocean below 200 metres, encompasses half of the world’s total ocean estate. To this day, just 5 per cent of the ocean abyss has been explored. It is only in the last decade that major advances in ocean-exploring technology, growing demand for metals used for tech gadgets, and the diminishing availability of these metals on land has created the burgeoning industry of deep sea mining.
This year, Canadian-registered company Nautilus Minerals Inc. is slated to begin Solwara 1, an operation in Papua New Guinea that will extract seafloor massive sulphides from hydrothermal vent ecosystems in the deep sea. Each year, this operation plans to extract 1.3 million tonnes of vent and seabed material high in copper, zinc, gold and silver.
Extraction requires a process of directly drilling, removing, and flattening down the vents and chimneys, essentially leaving a pile of rubble in its place.
“All deep sea mining removes material from the seafloor,” says Dr. Kirsten Thompson, a marine mammal scientist and ecology lecturer at the University of Exeter in Devon, United Kingdom. “In removing this material, the habitat and species that are associated with the ecosystem are destroyed.”
“For some types of mining, this destruction is irreversible on a local scale and recovery is not expected within our lifetimes,” says Thompson.
Mineral rich regions in the deep sea are also rich in ocean life. According to Dr. Thompson, hydrothermal vents and seamounts provide critical habitat for marine animals.
Vents are cracks in the ocean floor that spew heated water and nutrients into the frigid deep sea.
“Hydrothermal vents are ecosystems where species are uniquely adapted for extreme conditions,” says Thompson. “Research suggests that 85 per cent of vent species are found in no other ecosystem and there are many new species being discovered as research progresses.”
Seamounts are vast ranges of underwater mountains that rise from the ocean abyss, often bringing upwellings of nutrients that support a diversity of marine life.
In some cases, “seamounts provide habitat for a high diversity of corals, anemones and feather stars, as well as fish,” says Thompson. “Large mobile marine species, such as whales and sharks, are known to gather over seamounts, using them as foraging or resting areas.”
Like their counterparts on land, these underwater oases are now being eyed for treasures beyond their ecological value.
Part of mining seamounts involves stripping their cobalt-rich crusts. This incredibly damaging process causes direct mortality to seabed organisms, and associated impacts up and down the marine food chain.
Likewise, the harvesting of manganese nodules removes fields of small metallic deposits, which take millions of years to form, removing mini-ecosystems that other seabed organisms rely on for habitat.
Before long, Canadian and international mining companies alike may start turning their attention towards Canadian waters — that is, if they haven’t already.
The Offshore Pacific Area of Interest off the west coast of Vancouver Island is of particular concern to conservationists.
This massive 139,700 square kilometre area has been proposed as a federal marine protected area, but does not yet have protections from future mining interests.
Dubbed the “Deepsea Oasis” by ocean protection advocates, the offshore area contains several hydrothermal vents and 87 per cent of Canada’s seamounts.
The Canadian Parks and Wilderness Society has been working to ensure protections for the area address a range of threats, including shipping traffic, commercial fishing, and the potential for deep sea mining.
Despite the implications of the term, marine protected areas often allow for a variety of industrial activities to continue. When these activities overlap with vital ocean habitat, the results can be disastrous.
Conservationists and scientists are fighting to improve standards for ocean protection, but the federal government is moving slowly to adopt adequate minimum standards.
While mining companies like Nautilus are forging ahead with plans for major extractive operations, the science community is rushing to catch up.
Even preliminary studies are revealing incredible discoveries: the world’s most heat-tolerant microbe, with the ability to survive in over 121°C; ancient glass sponge reefs, which filter and clean vast amounts of water; and carbon-storing vents that may play a role in climate regulation.
Discoveries such as these could have vast applications to medicine, pharmaceuticals, disease prevention, genetic resources, and the advancement of scientific understanding.
Much of the world’s mining resources are found in the High Seas, an area outside of national jurisdiction, managed by the International Seabed Authority (ISA). The ISA has granted 29 licenses for mineral exploration without the existence of international guidelines on deep sea mining.
Canada has the world’s largest coastline and holds some of the global ocean’s most valuable deep sea ecosystems.
Before mining companies step in, areas like the Deepsea Oasis need protection in the form of firm guidelines against mining activities within marine protected areas.
Otherwise, one of our last remaining strongholds for ocean life could fade into the void.
And since you’re here, we have a favour to ask. Our independent, ad-free journalism is made possible because the people who value our work also support it (did we mention our stories are free for all to read, not just those who can afford to pay?).
As a non-profit, reader-funded news organization, our goal isn’t to sell advertising or to please corporate bigwigs — it’s to bring evidence-based news and analysis to the surface for all Canadians. And at a time when most news organizations have been laying off reporters, we’ve hired five journalists over the past year.
Not only are we filling a void in environment coverage, but we’re also telling stories differently — by centring Indigenous voices, by building community and by doing it all as a people-powered, non-profit outlet supported by more than 3,500 members.
The truth is we wouldn’t be here without you. Every single one of you who reads and shares our articles is a crucial part of building a new model for Canadian journalism that puts people before profit.
We know that these days the world’s problems can feel a *touch* overwhelming. It’s easy to feel like what we do doesn’t make any difference, but becoming a member of The Narwhal is one small way you truly can make a difference.
If you believe news organizations should report to their readers, not advertisers or shareholders, please become a monthly member of The Narwhal today for any amount you can afford.
