Editor’s Note: Deep sea mining is being pursued on the pretext of a transition towards a “cleaner” source of energy. This transition is being hailed as “the solution” to all environmental problems by the majority of the environmental movement. The irony of “the solution” to environmental problems being destruction of natural communities seems to be lost on a lot of people.
The International Seabed Authority has been criticized for a lack of transparency and corporate capture by the companies it is supposed to regulate. Given that the organization is expected to be funded from mining royalties, it may not come as a surprise that it has prioritized the interests of corporations above the preservation of the deep sea. Despite numerous concerns raised about Nauru Ocean Resources Inc. (NORI)’s environmental impact statement, the ISA gave permission to NORI to begin exploratory mining. NORI’s vessel, The Hidden Gem, is currently extracting polymetallic nodules from the seafloor in the Clarion Clipperton Zone. This exploratory mining will cause tremendous harm itself, but it is also a big step towards opening the gates to large-scale commercial exploitation of the deep sea. To help stop this, get organized, become a Deep Sea Defender.
The International Seabed Authority (ISA), the intergovernmental body responsible for overseeing deep sea mining operations and for protecting the ocean, recently granted approval for a mining trial to commence in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.
The company undertaking this trial is Nauru Ocean Resources Inc (NORI), a subsidiary of Canadian-owned The Metals Company (TMC), which is aiming to start annually extracting 1.3 million metric tons of polymetallic nodules from the CCZ as early as 2024.
The approval for this mining test, the first of its kind since the 1970s, was first announced by TMC earlier this week.
Mining opponents said the ruling took them by surprise and they feared it would pave the way for exploitation to begin in the near future, despite growing concerns about the safety and necessity of deep sea mining.
On Sept. 14, the Hidden Gem — an industrial drill ship operated by a subsidiary of The Metals Company (TMC), a Canadian deep sea mining corporation — left its port in Manzanillo, Mexico. From there, it headed toward the Clarion-Clipperton Zone (CCZ), a vast abyssal plain in international waters of the Pacific Ocean that stretches over 4.5 million square kilometers (1.7 million square miles) across the deep sea, roughly equivalent in size to half of Canada.
The goal of TMC’s expedition is to test its mining equipment that will vacuum up polymetallic nodules, potato-shaped rocks formed over millions of years. The nodules contain commercially coveted minerals like cobalt, nickel, copper and manganese. TMC, a publicly traded company listed on the Nasdaq exchange, announced that it aims to collect 3,600 metric tons of these nodules during this test period.
This operation came as a surprise to opponents of deep-sea mining, mainly because of the stealth with which they said the International Seabed Authority (ISA) — the UN-affiliated intergovernmental body dually responsible for overseeing mining in international waters and for protecting the deep sea — authorized TMC to commence the trial.
It is the first such trial the ISA has authorized after years of debate over whether it should permit deep-sea mining to commence in international waters, and if so, under what conditions. News of the authorization did not come initially from the ISA, but from TMC itself in a press release dated September 7. The ISA eventually posted its own statement on Sept. 15, more than a week after TMC’s announcement. It is not clear when the ISA granted the authorization.
“We’ve been caught off guard by this,” Arlo Hemphill, a senior oceans campaigner at Greenpeace, an organization campaigning to prevent deep sea mining operations, told Mongabay in an interview. “There’s been little time for us to react.”

Mounting concerns, sudden actions
Several weeks ago, in July and August, delegates to the ISA met in Kingston, Jamaica, to discuss how, when and if deep sea mining could begin. In July 2021, discussions acquired a sense of urgency when the Pacific island state of Nauru triggered an arcane rule embedded in the United Nations Convention on the Law of the Sea (UNCLOS) that could obligate the ISA to kick-start exploitation in about two years with whatever rules are in place at the time. Nauru is the sponsor of Nauru Ocean Resources Inc (NORI), a subsidiary of TMC that is undertaking the tests. TMC told Mongabay that it expects to apply for its exploitation license in 2023, and if approved by the ISA, to begin mining towards the end of 2024.
The ISA subsequently scheduled a series of meetings to accelerate the development of mining regulations, but has yet to adopt a final set of rules.
The delay is due, in part, to the increasing number of states and observers from civil society raising concerns about the safety and necessity of deep sea mining. Some member states, including Palau, Fiji and Samoa, have even called for a moratorium on deep sea mining until more is understood about the marine environment that companies want to exploit. Other concerns hinge upon an environmental impact statement (EIS) that NORI had to submit in order for mining to begin.
NORI submitted an initial draft of its EIS in July 2021, as per ISA requirements, and an updated version in March 2022.
Matt Gianni, a political and policy adviser for the Deep Sea Conservation Coalition (DSCC), a group of environmental NGOs calling for NORI’s testing approval to be rescinded, said that the ISA’s Legal and Technical Commission (LTC) — the organ responsible for issuing mining licenses — previously cited “serious concerns” about NORI’s EIS, including the fact that it lacked baseline environmental data. The LTC had also raised concerns about the comprehensiveness of the group’s Environmental Management and Monitoring Plan (EMMP), he said.
But then, “all of a sudden,” the LTC granted approval for the mining test without first consulting ISA council members, said Gianni, who acts as an observer at ISA meetings.
The fact that TMC announced the decision before the ISA did “reinforces the impression that it’s the contractor and the LTC and the [ISA] secretariat that are driving the agenda, and states are following along,” Gianni said.
Harald Brekke, chair of the LTC, sent Mongabay a statement similarly worded to the recent announcement made by the ISA. He said that the LTC had reviewed NORI’s EIS and EMMP for “completeness, accuracy and statistical reliability,” and that an internal working group had worked closely with NORI to address concerns. In response, the mining group adequately dealt with the issues, which allowed the LTC to approve the proposed testing activities, he said.
“This is a normal contract procedure between the [ISA] Secretary-General and the Contractor, on the advice and recommendations by the [Legal and Technical] Commission,” Brekke said in the emailed statement. “It is not a decision to be made by the [ISA] Council. According to the normal procedure of ISA, the details of this process will be [communicated] by the Chair of the Commission to the Council at its session in November.”
“I also would like to point out that this procedure has followed the regulations and guidelines of ISA,” Brekke added, “which are implemented to take care of the possible environmental impacts of this kind of exploration activity.”
Yet Gianni said he did not believe the LTC had satisfactorily reviewed the EIS for its full potential of environmental impact, nor had it considered the “serious harmful effects on vulnerable marine ecosystems” as required under the ISA’s own exploration regulations for polymetallic nodules.
Questions about transparency
Sandor Mulsow, who worked as the director of environment and minerals at the ISA between 2013 and 2019, said that the ISA “is not fit to carry out an analysis of environmental impact assessment” and that the grounds on which the ISA authorized NORI to begin testing were questionable.
“Unfortunately, the [International] Seabed Authority is pro-mining,” Mulsow, who now works as a professor at Universidad Austral de Chile, said in an interview with Mongabay. “They’re not complying with the role of protecting the common heritage of humankind.”
A recent investigation by the New York Times revealed that the ISA gave TMC critical information over a 15-year period that allowed the company to access some of the most valuable seabed areas marked for mining, giving it an unfair advantage over other contractors.
The ISA has also frequently been criticized for its lack of transparency, including the fact that the LTC meets behind closed doors and provides few details about why it approves mining proposals. The ISA has previously granted dozens of exploratory mining licenses to contractors, although none have yet received an exploitation license. While NORI is not technically undertaking exploratory mining in this instance, their testing of mining equipment falls under exploration regulations.
Mongabay reported that transparency issues were even prominent during the ISA meetings that took place in July and August this year, including restrictions on participation and limited access to key information for civil society members.
The ISA did not respond to questions posed by Mongabay, instead deferring to the statement from Brekke, the LTC chair.

‘Full-blown mining in test form’
During the mining trial set to take place in the CCZ — which could begin as early as next week — NORI will be testing out its nodule collector vehicles and riser systems that will draw the nodules about 3,000 meters (9,840 feet) from the seabed to the surface. If NORI does begin exploitation in 2024, Gianni said the risers will be pumping about 10,000 metric tons of nodules up to a ship per day.
“That’s a hell of a lot,” Gianni said. “This is heavy duty machinery. This is piping that has to withstand considerable pressure.”
NORI intends to extract 1.3 million metric tons of wet nodules each year in the exploitation stage of its operation, TMC reported.
The Metals Company argues that this mining will provide minerals necessary to power a global shift toward clean energy. Indeed, demand for such minerals is growing as nations urge consumers to take up electric vehicles in an effort to combat climate change.
Mining opponents, however, have argued that renewable technologies like electric cars don’t actually need the minerals procured from mining.
Moreover, a growing cadre of scientists have been warning against the dangers of deep sea mining, arguing that we don’t know enough about deep sea environments to destroy them. What we do know about the deep sea suggests that mining could have far-reaching consequences, such as disturbing phytoplankton blooms at the sea’s surface, introducing toxic metals into marine food webs, and dispersing mining waste over long distances across the ocean — far enough to affect distant fisheries and delicate ecosystems like coral reefs and seamounts.
“Every time somebody goes and collects some sample in that area of the Clarion-Clipperton Zone, there’s a new species coming up,” Mulsow said. “We don’t know how to name them, and we want to destroy them.”
TMC has stated that the testing activities will be monitored by “independent scientists from a dozen leading research institutions around the world.”
However, Hemphill of Greenpeace, who also has ISA observer status, questions whether the monitoring process will be unbiased.
“We’re thinking there’s a high chance that these risers might not work,” he said. “But if there’s not a third party observer out there, then we just have to rely on The Metals Company’s own recording.”
“It’s going to be basically a full-blown mining operation in test form, where they’re not only using the [collector] equipment, but they’re using the risers to bring the nodules to the surface,” Hemphill added.
Nodule collection trials like the one NORI is undertaking haven’t been conducted in the CCZ since the 1970s, TMC noted in its press release.
When Mongabay reached out to TMC for further information about its operation, a spokesperson for the company said that they “believe that polymetallic nodules are a compelling solution to the critical mineral supply challenges facing society in our transition away from fossil fuels.”
“While concern is justified as to the potential impacts of any source of metals — whether from land or sea — significant attention has been paid to mitigate these, including by setting aside more area for protection than is under license in the Clarion-Clipperton Zone of the Pacific Ocean,” the TMC spokesperson said.
‘No way back’
Mulsow said he was sure that this trial would pave the way for exploitation to start next year, not only giving TMC’s NORI access to the deep sea’s resources, but opening the gates for other contractors to begin similar operations.
“[In June] 2023, we will have … the application for the first mining license for the deep sea,” he said, “and then there will be no way back.”
Hemphill said he also feared the move would set a process into motion for mining to start next year — but added that Greenpeace would continue its fight to stop mining.
“We’re not giving up just because the two-year rule comes to pass,” he said. “And then if things get started, we’re in this for the long haul.”
Gianni said he was hopeful that the dynamic could also change at the next ISA meeting scheduled for November, in which delegates will get the chance to discuss whether they’re obligated to approve the start of mining the following year.
“The fact that the LTC has done this … may finally get council members to start saying, ‘Wait a minute, we need to bring this renegade fiefdom [at] the heart of the ISA structure under control,” Gianni said, “because they’re going off and deciding things in spite of all the reservations that are being expressed by the countries that are members of the ISA.”

Editor’s note: By biomass, krill are the most abundant species in the world and the main food source for all baleen whales — including blue whales, the largest animals on the planet and the largest ever known to have existed.
Regardless of how abundant it is — see Passenger Pigeons, Buffalo, or Great Auks — any species that becomes economically valuable in a growth economy will likely experience decline and collapse. That is the nature of endless growth.
Krill are no different. Between overfishing that has more than quadrupled in 15 years and global climate destabilization that has already warmed the Antarctic by 2.5° C since the 1940s, Krill, like all life on Earth, are in trouble — yet another sign that industrial civilization is driving an ongoing ecological collapse and accelerating us deeper into the 6th mass extinction (an extermination, in this case) of life on Earth.
Antarctic krill are one of the most abundant species in the world in terms of biomass, but scientists and conservationists are concerned about the future of the species due to overfishing, climate change impacts and other human activities.
Krill fishing has increased year over year as demand rises for the tiny crustaceans, which are used as feed additives for global aquaculture and processed for krill oil.
Experts have called on the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the group responsible for protecting krill, to update its rules to better protect krill; others are calling for a moratorium on krill fishing.
Antarctic krill play a critical role in maintaining the health of our planet by storing carbon and providing food for numerous species.
Antarctic krill — tiny, filter-feeding crustaceans that live in the Southern Ocean — have long existed in mind-boggling numbers. A 2009 study estimated that the species has a biomass of between 300 million and 500 million metric tons, which is more than any other multicellular wild animal in the world. Not only are these teensy animals great in number, but they’re known to lock away large quantities of carbon through their feeding and excrement cycles. One study estimates that krill remove 23 million metric tons of carbon each year — about the amount of carbon produced by 35 million combustion-engine cars — while another suggests that krill take away 39 million metric tons each year. Krill are also a main food source for many animals for which Antarctica is famous: whales, seals, fish, penguins, and a range of other seabirds.
But Antarctic krill (Euphausia superba) are not “limitless,” as they were once described in the 1960s; they’re a finite resource under an increasing amount of pressure due to overfishing, pollution, and climate change impacts like the loss of sea ice and ocean acidification. While krill are nowhere close to being threatened with extinction, the 2022 report from the Intergovernmental Panel on Climate Change indicated that there’s a high likelihood that climate-induced stressors would present considerable risks for the global supply of krill.
“Warming that is occurring along the Antarctic Peninsula and Scotia Sea has caused the krill stocks in those areas to shrink and the center of that population has moved southwards,” Kim Bernard, a marine ecologist at Oregon State University, wrote to Mongabay via email while stationed in the Antarctic Peninsula. “This tells us already that krill numbers aren’t endless.”
Concerns are amassing around one place in particular: a krill hotspot and nursery at the tip of the Antarctic Peninsula known as “Area 48,” which harbors about 60 million metric tons of krill. Not only has this area become a key foraging ground for many species that rely on krill, but it also attracts about a dozen industrial fishing vessels each year. The amount of krill they catch has been steadily increasing over the years. In 2007, vessels caught 104,728 metric tons in Area 48; in 2020, they caught 450,781 metric tons.
The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the group responsible for protecting krill, has imposed rules to try and regulate krill fishing in the Southern Ocean, but many conservationists and scientists say the rules need to be updated to reflect the changing dynamics of the marine environment. That said, many experts argue that the Antarctic krill fishery can be sustainable if managed correctly.

Approaching krill ‘trigger level’
Fishing nations started casting their nets for Antarctic krill in the 1970s, believing these small crustaceans could provide a valuable source of animal protein that would alleviate world hunger. But in the 1980s, interest in krill fishing waned, partly because no one was sure how to remove the high levels of fluoride in their exoskeletons. It was also generally difficult to process krill into food fit for human consumption and to successfully sell these foods to consumers.
But krill fishing never really stopped. In fact, it’s been gaining momentum ever since krill was identified as a suitable animal feed. Now krill is mainly used as a feed additive in the global aquaculture industry, as well as to produce krill oil that goes into omega-3 dietary supplements.
In 1982, the CCAMLR was established to address concerns that the Antarctic krill fishery could have a substantial impact on the marine ecosystem of the Southern Ocean. In 2010, the CCAMLR established a rule limiting catches to 5.61 million metric tons across four subsections of Area 48 where krill fishing was concentrated. The rule also dictated that krill fishing in these areas must stop if the total combined catch reached a “trigger level” of 620,000 metric tons.
So far, total catches have not exceeded this boundary. But krill fishing nations, which currently include Norway, China, South Korea, Ukraine and Chile, are inching closer to it as they expand their operations.
“As long as catches were significantly below the trigger level, I think people felt like, ‘Oh, we don’t need to be too worried,’” Claire Christian, executive director of the Antarctic and Southern Ocean Coalition (ASOC), told Mongabay. “They’re still not there yet, but as they’ve been getting closer, there’s been more pressure on CCAMLR scientists and policymakers to look at the fishery and develop a more comprehensive management system.”
Stuart Corney, an Antarctic krill expert at the University of Tasmania, said a primary concern is that most krill fishing is concentrated at the tip of the Antarctic Peninsula, where krill are known to spawn, creating “localized depletion.”
“If we overexploit the krill in that region, it can have significant implications for the population in a greater area of Antarctica … so it needs to be carefully managed efficiently,” Corney told Mongabay.
Another issue with the current catch limits is that they don’t consider the impacts of climate change, according to Bernard.
“This is particularly important at the Antarctic Peninsula where the fishing effort is greatest because the Antarctic Peninsula is one of the most rapidly warming regions on the planet,” Bernard said. “There is also evidence that areas along the Antarctic Peninsula such as the Gerlache Strait are important overwintering grounds for Antarctic krill, particularly for the juveniles and larvae that shelter in the bays and fjords along the Peninsula at that time of year. There is no seasonal closure on the krill fishery and because of delayed sea ice formation in the region around the Gerlache Strait the fishery can extend into winter. When that happens, the fishery could remove massive numbers from the next reproductive cohort of the population.”

Not only will global heating deplete the sea ice that krill depend upon, but research has suggested that warming waters will impact krill growth, possibly leading to a 40% decline in the mass of individual krill by the end of the century. Other research has argued that ocean acidification, another impact of climate change, will reduce krill development and hatchling rate and lead to an eventual collapse in 2300.
Progress and setbacks
In 2019, CCAMLR members agreed on a scientific work plan with the view of adopting new conservation measures based on it in 2021. This process was delayed due to COVID-19, but CCAMLR members are expected to reinvigorate these discussions at the next meeting in October, said Nicole Bransome, a marine ecologist at Pew Bertarelli Ocean Legacy.
“Hopefully, the scientists will have been able to put all of the science together … and come up with a new measure that spreads the catch out in space to reduce the impacts on predators,” Bransome told Mongabay. However, she said she’s concerned about a possible move to increase krill catch limits, which was discussed at last year’s meeting.
“Preliminary analysis suggests that the overall catch level could go up, but as of last year’s meeting, there were still a lot of uncertainties with that model and the parameters used in that model,” she said. “We would rather see that if the catch limits change, they’re based on a robust model and good science.”
While many experts say krill fishing can be sustainable if managed correctly, others call for stronger measures to protect krill.
Over the past decade, conservationists and scientists have been proposing the establishment of three new marine protected areas (MPAs) in East Antarctica, the Antarctic Peninsula and the Weddell Sea, ranging over 4 million square kilometers (1.5 million square miles) of the Southern Ocean, which would help protect krill with no-take zones.
“There is now strong scientific evidence that we need strict protection of at least 30% of the global ocean to effectively protect it,” said Christian of ASOC.
Yet the CCAMLR, which makes decisions based on consensus, has rejected the MPA proposal year after year.
Sophie Nodzenski, a senior campaigner at the Changing Markets Foundation, an NGO that works to expose irresponsible corporate practices and to foster sustainability, said the CCAMLR’s continued rejection of the MPAs had led her organization to call for a moratorium on krill fishing. (The Bob Brown Foundation, an Australian NGO that works to protect the natural world, has previously called for a similar ban on krill fishing to be put in place.)
“We are aware it’s a strong stand,” Nodzenski told Mongabay. “But there is a climate emergency, and there is a worry about how krill fishing is exacerbating the threats from climate change. So why don’t we just put a moratorium in place?”
In a report released Aug. 11 — for the first World Krill Day — the Changing Market Foundation details concerns for the planned expansion of the krill industry, which could push catch limits past the current trigger points. It also reveals how Norwegian company Aker Biomarine dominates the industry, supplying krill feed for farmed salmon operations around the world.
Consumers could alleviate pressure on krill “by pushing for a change in the way we are harvesting krill,” Nodzenski said. “If there’s less demand for products, eventually you could see a knock-on effect on the krill harvesting.”

Is change coming?
The report also casts doubt on the CCAMLR’s ability to make timely decisions to protect krill.
“This is because CCAMLR’s decision-making process is based on consensus; as long as some members oppose changes to the status quo (in this regard, China and Russia), decisions cannot go ahead,” the authors write. “This means that, for the foreseeable future, it is difficult to envisage how management measures regarding krill can evolve and adapt to our rapidly changing climate.”
Yet other experts say the CCAMLR has the capacity to authorize effective changes.
“CCAMLR has a range of mechanisms it can use to further ecosystem protection,” Bransome of Pew Bertarelli Ocean Legacy said. “Lots of progress has been made … and we are looking to CCAMLR to achieve additional protections at the upcoming CCAMLR meeting.”
Corney from the University of Tasmania said he believes it’s important for fishing nations to continue working together through the CCAMLR to protect the Southern Ocean.
“If some nations started pulling out of CCAMLR … they’re not bound by the rules [and] they can do their thing,” Corney said. “We want all nations to remain in CCAMLR. We want them to sign up for the agreements that are reached. That means we have to accept the structure that is there.”
While opinions differ about how to manage the krill fishery, experts tend to agree on one thing: krill are too valuable to lose in this moment of climate crisis.

“Even though Antarctic krill are seemingly far removed from our lives, some of that excess carbon dioxide we’ve pumped into the air is exported to the sea floor by krill, where it will remain for thousands of years,” Bernard said. “Without Antarctic krill, Earth would be even hotter than it already is.”

Editor’s note: Deep-sea mining is a sign of addiction. Only a culture driven by a death urge masquerading as a profit-production-motive could contemplate destroying some of the largest and most intact remaining habitats on Earth and call it “green.” One of the first companies that may begin deep sea mining is The Metals Company, headquartered in Vancouver, Canada. TMC plans to extract nickel, cobalt, copper, and manganese from “polymetallic nodules” dredged from the deep seafloor in an area of international waters called the Clarion Clipperton Zone southwest of San Diego. The company claims that mining the oceans is less harmful to the environment. Nothing could be further from the truth.
As a biocentric organization, Deep Green Resistance is opposed to deep-sea mining — and indeed, all industrial mining. Mining is the one of the most destructive industries on the planet in terms of habitat destruction, pollution, and social injustice. Modern industrial civilization is fully dependent on mining, and as an organization dedicated to dismantling industrial civilization, we oppose and will fight all industrial mining activities. We put the planet first.
This week, the International Seabed Authority, the intergovernmental body tasked with overseeing deep-sea mining in international waters, concluded its recent set of meetings, which ran from July 4 to Aug. 4, 2022.
The purpose of these meetings was to progress with negotiations of mining regulations, with a view that deep-sea mining will start in July 2023 after the Pacific island nation of Nauru triggered a rule that could obligate this to happen.
While many countries appear to support the rapid development of these regulations, an increasing number of other countries have expressed concern with this deadline, indicating a possible turn of events.
It starts with tiny deep-sea fragments — shark’s teeth or slivers of shell. Then, in a process thought to span millions of years, they get coated in layers of liquidized metal, eventually becoming solid, lumpy rocks that resemble burnt potatoes. These formations, known as polymetallic nodules, have caught the attention of international mining companies because of what they harbor: rich deposits of commercially sought-after minerals like cobalt, nickel, copper and manganese — the very metals that go into the batteries for renewable technologies like electric cars, wind turbines, and solar panels.
But while some experts say we must mine the deep sea to combat climate change, others warn against it, saying we know too little about the damage that seabed mining would cause to the ocean’s life-sustaining properties.
Actual extraction has yet to begin, but in June 2021, the small Pacific island country of Nauru pushed the world closer to this possibility by notifying the International Seabed Authority — the intergovernmental body that oversees mining in international waters — that it had triggered a two-year rule in the United Nations Convention on the Law of the Sea (UNCLOS). This rule would theoretically allow it to start mining in June 2023 under whatever mining rules are in place by then. Nauru itself doesn’t have a mining company with this interest, but it sponsors a subsidiary of Canada-based and U.S.-listed The Metals Company.
Since then, the ISA has been working to negotiate a set of regulations that would allow it to follow the two-year rule. But at the latest set of meetings that took place between July 4 and Aug. 4 in Kingston, Jamaica, progress on the mining code appears to have stalled, observers reported.

“Overall, the feeling in the room is that there’s now a majority of states that are recognizing that it’s unrealistic, unachievable, and would be highly irresponsible,” Emma Wilson, a conservation expert who attended the recent ISA meetings as a representative of the NGO OceanCare, told Mongabay.
Representatives from several countries, including Spain, Chile, New Zealand, Ecuador, Costa Rica, the Federated States of Micronesia, and Trinidad and Tobago, made the case that the mining regulations shouldn’t be rushed to meet the obligations of the two-year rule. Spain’s representative, for instance, said that “as a precaution, the time has come to take a break,” while Costa Rica’s representative said “because we are responsible for the Common Heritage of Humankind, for our peoples and for future generations, we must act with caution.” (The UNCLOS defines the seabed and its resources as “the common heritage of mankind.”)
However, other countries, such Australia, the U.K., Tonga, and Nauru itself, took the position that regulations should be approved without delay. Tonga’s representative said the nation stood “ready to support work of Authority and relevant bodies especially for completion of regulatory frameworks in [a] timely fashion while assuring due diligence where appropriate.” Even France stated that it was committed to adopting “a legal framework with rigorous environmental protections to ensure that harm to ecosystems in the marine environment is minimized.” This position seemed to be in contrast to President Emmanuel Macron’s statement at the U.N. Ocean Conference in Lisbon at the end of June that “we have to create the legal framework to stop high seas mining and not to allow new activities that endanger ecosystems.”
On July 25, Chile’s delegation presented a letter to the ISA Secretariat, requesting that a discussion about the two-year rule become an agenda item at the assembly portion of the meetings, which began on Aug. 1. But this request was ignored, OceanCare’s Wilson said. Instead, the ISA Secretariat relegated it to the end of the meeting in the “any other business” category, which “undermined it,” and the ISA Secretariat even closed the meetings a day early, she added.
“One thing that became very, very evident this week is that the ISA Secretariat is doing everything that it can to brush the conversation under the carpet about [whether] there is another possibility of not adopting the regulation,” Wilson said.
Mongabay previously reported on concerns about transparency at the recently concluded ISA meetings, including accusations that the ISA had restricted access to key information and hampered interactions between member states and civil society.

Despite the many setbacks, Matt Gianni, a political and policy adviser for the Deep Sea Conservation Coalition (DSCC), told Mongabay that he was observing a change happening in the negotiations.
“There’s a broad recognition that unless something really surprising happens, these regulations are not only unlikely to be adopted by July 2023, but they’re probably not likely to be adopted for several years at least,” said Gianni, who attended the meetings as a representative of EarthWorks, an NGO that works to shield communities and the environment from the negative impacts of extractive activities.
Gianni added that the ISA council has also yet to agree upon the financial mechanisms under which mining could operate, which need to be put into place, in addition to the regulations, before the ISA can issue exploitation licenses. However, he said it’s still unclear whether deep-sea mining will officially be stalled.
“It’s a bit like the Titanic,” Gianni said. “We’re starting to see the rivets popping and the thing is slowly starting to turn. But is it going to miss the iceberg and head in the direction of protecting the marine environment? That’s still an open question.”

Editor’s note: The oceans have absorbed more than 90% of the excess heat trapped on planet earth due to global warming. Greenhouse gases are also absorbed into the ocean which has increased the acidity of ocean water significantly. Increased heat and acidity makes reproduction and survival more difficult for calcifying organisms such as corals and other marine life. It should be no surprise to anyone that we see coral reefs dying globally. So are plankton populations, fish populations, and countless other species. What is surprising is that efforts to halt and reverse greenhouse gas emissions have thus far been so tepid and ineffective. We must change that.
Article summary:
In 2003, a marine heat wave devastated coral reef communities in the Mediterranean Sea, including the reefs in the Scandola Marine Reserve, a protected region off the coast of Corsica.
More than 15 years later, the coral reef communities in Scandola still have not recovered.
Researchers determined that persistent marine heat waves, which are now happening every year in the Mediterranean, are preventing Scandola’s slow-growing coral reefs from recuperating.
Human-induced climate change is the culprit; persistent rising temperatures in the ocean have normalized marine heat waves, not only in the Mediterranean, but in the global oceans.
For years, Joaquim Garrabou donned scuba gear and dove into the waters of the Scandola Marine Reserve in Corsica to find a paradise. Twenty meters (66 feet) beneath the surface, there were reef walls draped with soft red coral (Corallium rubrum) and red gorgonian sea-whips (Paramuricea clavata), all swarming with fish and other sea creatures. But in 2003, a marine heat wave hit Scandola, leading to the death of many coral reefs. More than 15 years later, the reefs have still not recovered.
Now when Garrabou dives at Scandola, he’s greeted by the skeletons of once-thriving corals.
“It’s like seeing someone who is ill, who has a disease that you cannot find the solution for,” Garrabou told Mongabay in a video interview. “You hope that someday there will be a [solution] but you see that there’s not much hope.”
After the 2003 marine heat wave, Garrabou and colleagues began monitoring Scandola’s coral reefs to track their recovery. But after accumulating reef survey data and temperature data over many years, they eventually realized they were actually tracking the reefs’ collapse. The results of their long-term study were recently published in Proceedings of the Royal Society B.
“We knew something bad was happening to the corals around the world, but we weren’t expecting a collapse in all of the populations that we studied,” study lead author Daniel Gómez-Gras, a marine ecologist at the Institut de Ciències del Mar in Barcelona, told Mongabay in a video interview. “The point of tracking these populations for such a long time was to show recovery in the long term because we expected that the populations — maybe not in five years, but in 15, 20 years — [would be] able to recover. However, we saw a collapse.”

‘We don’t call it bleaching’
The data showed that marine heat waves were happening every year in different parts of the Mediterranean between 2003 and 2018. For 12 of those years, the water temperature at a depth of 20 m reached more than 23° Celsius (73.4° Fahrenheit), which is considered a sublethal threshold for corals. And for four of those years — 2009, 2016, 2017 and 2018 — temperatures at that depth breached the lethal threshold for corals at 25°C (77°F).
The researchers found that the ceaseless heat wasn’t allowing these slow-growing coral reefs to recover.
“Frankly, I never thought that I would be seeing it,” Garrabou said. “And it’s happening really fast.”
Soft coral species in the Mediterranean don’t “bleach” the way that tropical corals do, Gómez-Gras said. That’s because Mediterranean corals don’t have a symbiotic relationship with zooxanthellae, the algae that tropical corals expel when they experience heat stress.
“We don’t call it bleaching here in the Mediterranean for these coral species, since they don’t bleach,” he said. “They directly die with a loss of tissue and skeletons being exposed.”
While the results of the study are relevant to many coral communities across the Mediterranean, the researchers chose to focus their study on Scandola because the area had been established as a marine protected area (MPA) in 1975, and had been relatively free from other human pressures such as fishing and pollution. This helped them eliminate other possibilities for the coral reef population collapses and to pinpoint marine heat waves as the reason for their demise.
Researchers used to think that deeper reef communities might shelter coral species from heat stress. But it’s becoming increasingly clear that this isn’t the case, not only in the Mediterranean, but in other parts of the world, including coral reef sites in the Pacific.
“We are witnessing that if you go deeper, [there is still] impact,” Garrabou said.

Raised temperatures
Human-induced climate change is responsible for the heating of the oceans — and it’s becoming hotter and hotter in the water. According to another study, the global oceans have broken a heat record for the sixth year in a row. As the oceans warm, heat penetrates downward — and this heating trend will continue even if emissions stop tomorrow, Kevin Trenberth, co-author of this separate study, told Mongabay in January.
A related study also found that marine heat waves have become the new normal for the global oceans as climate change rapidly transforms our world.
The Mediterranean may be feeling the impacts of climate change even more intensely than other parts of the world. A report published last year by WWF found that the Mediterranean was warming 20% faster than the rest of the world’s oceans.
Gómez-Gras said the accelerated warming in the Mediterranean has partly to do with its semi-enclosed shape. While this is unique to the region, he added that the Mediterranean shows what will happen in other parts of the ocean due to climate change.
“Marine heat waves are becoming the new normal in the Mediterranean Sea,” Gómez-Gras said. “So you can guess that in the future, it can become the new normal [elsewhere] in the world.”
Georgios Tsounis, a marine biologist at California State University, whose work was based in the Mediterranean for 11 years, but who was not involved in this research, praised the new study in Proceedings of the Royal Society B for its “valuable approach.”
“We need more long-term demographic studies such as this one to better understand where our environment is heading in the future,” Tsounis told Mongabay in an email.
While the study is focused on the soft coral communities of the Mediterranean, Tsounis said the research can help us understand how other coral communities “may or may not recover from repeated stress over a period of 15 years.”
“We are seeing coral mortality in other parts of the world as well,” he said. “The tropical coral reefs make sad headlines every year. But in the tropics we are mainly concerned with reef-building hard corals (as opposed to the soft corals in this Mediterranean study). The temperature range and entire cause-effect mechanism differ between these two examples. What is common to most of these scenarios is that the corals have adapted to a narrow set of environmental conditions, such as temperature, over a long period of time, and are sensitive to changing climate.”

Seeking refuge
The researchers said they are searching the Mediterranean for “refugia,” places that offer coral reefs protection from thermal stress. One possible place could be the waters off the coast of the Calanques near Marseille, France, which seems to get enough cold water to protect its corals, Garrabou said. That said, the coral reef communities here experienced mass die-offs during marine heat waves in both 1999 and 2003. But since then, the region hasn’t had any major warming, and the corals have been able to slowly recover, he said.
While there are currently many places of refugia for coral communities across the world, a new study found that most of these places will disappear once the world reaches 1.5°C (2.7°F) of warming above pre-industrial levels, which is likely to happen within the next decade.
But it’s not just climate change placing pressure on the Mediterranean — fishing and pollution are additional stressors to the region. Because of this, Garrabou said it’s important to establish MPAs with strict protective measures to enhance the resilience of coral reef communities.
Currently, there are more than 1,200 MPAs in the Mediterranean, but only about 0.02% of the area they cover is closed to fishing year-round.
While the future looks grim for coral reefs, Garrabou said he feels hopeful about the momentum that’s building for the establishment of MPAs, especially with global efforts to protect 30% of the world’s oceans by 2030.
“When we provide the right conditions and the right tools, nature can be really generous and nature has demonstrated that it can bounce back,” he said.
But he said that MPAs need to be urgently established for the oceans to reap their benefits. “It has to happen,” he said, “and it has to happen fast.”

Editor’s note: Already threatened by overfishing, acidification, overheating, the collapse of coral reefs, declining plankton populations, plastic pollution, and deep sea oil drilling, the world’s oceans now face a new threat: mining, disguised as “green.”
“To build a green future, in the next couple of decades the world will need to mine more metal than we’ve mined in our entire history” says Gerard Barron, CEO of The Metals Company.
There’s some truth to that statement – if we wish to meet the rising demand for new technologies, we’d need to see a sharp increase in metal extraction. After all, electric vehicles require 4x the amount of metals found in standard cars, and a single wind turbine requires 340 tonnes of metal.
Here’s the problem: the ‘green future’ he’s selling us is a lie, because what Barron fails to divulge in his upbeat sales pitch, is the ecological upheaval that his company’s plans would surely wreak.
The Metals Company plans to mine the seabed for polymetallic nodules; potato-sized objects containing metals like nickel, copper, and cobalt; essential in the production of the lithium-ion batteries being used for electric cars and (so-called) renewable energy storage.
They’re located (among other places) in the Clarion-Clipperton zone, an area of the Pacific Ocean equivalent in size to the entire Indian Subcontinent. The seabed here (despite the claims of company officials) isn’t simply a ‘vast marine desert’, it’s home to a wide variety of species whose existence depends upon the presence of these nodules.
So, what would the mining process actually look like?
They’re building house-sized machines which would indiscriminately vacuum-up the contents of the seabed and send it to a ship on the surface. This includes an estimated 2 to 6 million cubic feet of marine sediment (granulated rock) per day for every machine in operation, only then to be subsequently dumped right back into the ocean.
It’s been stated that the sediment will be returned to a depth below 1200m. That’s called the Bathypelagic zone (Midnight Zone) – and some animals who live there include viperfish, anglerfish, frill sharks, eels, and sperm whales. These would be among the first creatures to acquire a gill-full of gravel.
But furthermore, the floating particles could be carried throughout the entire water column by powerful currents in a natural process called ‘downwelling’ & ‘upwelling’ – damaging (perhaps fatally) the respiratory systems of billions of fish.
This, plus the impact that light & sound disturbances from mining equipment would have on creatures adapted to conditions of silence & darkness, raises the likelihood of ecosystem collapse. Ocean ecosystems are already threatened by multiple stressors like overfishing, ocean acidification, & plastic pollution – do we really want to add anything else to the list?
The Metals Company claims that seabed extraction is a more ‘sustainable’ method of sourcing metal than land-based mining. Whenever anyone pulls-out the ‘sustainability’ buzzword, two premises need to be addressed:
#1: what are they sustaining? – clearly not biodiversity.
#2: how long do they wish to sustain it for?
The answer to the first question: an industrial way of life. The way of life which propels us to greedily squander nature’s bounty.
The answer to the second question: for as long as there’s anything left of the living world to convert into commodities.
This isn’t about saving the planet. It’s about creating new technologies which will prolong & exacerbate the destruction of the planet, and a false narrative that this is all somehow morally justifiable. Here’s a basic rule: if we consume the Earth at a rate faster than it can regenerate – eventually there won’t be anything left to take. Even Gregory Stone (chief scientist at The Metals Company) acknowledges this:
“On-land commodities are being exhausted…and [the deep sea] is the natural next place to look…these are some of the last resources that the Earth has to give us”.
Are we really prepared to blow-through everything that’s left? To leave no stone (or nodule) left unturned, just so that we can continue driving around in cars & tooting our horns?
The ends don’t really justify the means. Any right-minded, white westerner can reflect upon the cruelty of the transatlantic slave trade and conclude: “Yikes, my ancestors should’ve left the people of West Africa alone”.
Jazz music probably wouldn’t have existed without the transatlantic slave trade. Do I like jazz music? Sure, but you know what I like better? Thriving communities living in environments to which they’re socially and biologically adapted.
Communities like the ocean-dwelling phytoplankton who generate 80% of the Earth’s oxygen, who play a crucial role in atmospheric carbon regulation, and whose future hangs in the balance should deep-sea mining go ahead.
So, what can we do to stop this from happening?
The country of Nauru, which (having signed a contract with The Metals Company) would stand to benefit financially from deep sea mining, have declared that operations will go ahead in 2024, within waters assigned to them by the ISA (International Seabed Authority) – that means we have about two years to stop this.
So far, campaigners such as Greenpeace, WWF, and the government of Fiji have collaborated on a proposed 10-year moratorium (temporary ban) on deep sea mining until more is known about its effects on deep sea ecosystems.
Going a step further, organisations like Blue Planet Society and Pacific Blue Line are calling for an outright ban.
You (the reader) can help by educating yourself more on the subject, by spreading awareness, by signing online petitions, and by joining or organizing demonstrations against deep sea mining…but before you go and do those things, let me finish with a final appeal:
As environmentalists, we might not instinctively care quite as much about the deep sea as we do about other landscapes like rainforests or prairies. We’re land mammals after all; we don’t belong down there, and neither should we strive to assimilate. However, it’s important that we look beyond our human bias, because the deep sea comprises 60% of Earth’s surface. This means that the wellbeing of the ocean is crucial for the wellbeing of the planet as a whole.
Industrialists can’t understand this. They look upon the deep sea as a challenge, as another frontier just waiting to be conquered, and none of the native beings who live there will stand in their way.
We can stand in their way.
Help to stop deep sea mining, before it starts.
