Threatened Whale Species In The Pacific Found In Areas Targeted By The Metals Company For Deep Sea Mining
The survey published today in the scientific journal Frontiers in Marine Science was conducted by researchers from the University of Exeter and Greenpeace Research Laboratories from Greenpeace Internationals ship, Arctic Sunrise.
A scientific survey of two areas targeted by The Metals Company for deep sea mining in the Pacific Ocean has confirmed the presence of whales and dolphins, including sperm whales, which are listed as vulnerable on the IUCN Red List of Threatened Species. The news comes as world governments are preparing to meet once again at the International Seabed Authority (ISA), where the call for a moratorium on deep sea mining keeps growing.
The survey published today in the scientific journal Frontiers in Marine Science was conducted by researchers from the University of Exeter and Greenpeace Research Laboratories from Greenpeace International's ship, Arctic Sunrise. Researchers studied two exploration blocks held by The Metals Company in the Pacific's Clarion-Clipperton Zone (known as NORI-d and TOML-e) [1] [2]
Dr Kirsten Young, Lead Study Author, University of Exeter, says, 'We already knew that the Clarion-Clipperton Zone is home to at least 20 species of cetaceans, but we've now demonstrated the presence of some of these species in two areas specifically earmarked for deep sea mining by The Metals Company.'
Following President Trump's approval of a deep sea mining Executive Order in April 2025, The Metals Company applied to the US government to give TMC unilateral permission to commercially mine the international seabed in the Clarion-Clipperton Zone. According to reports, this application covers the NORI-d area. This move bypasses and undermines the International Seabed Authority, the UN regulator for deep sea mining, which continues to prohibit commercial mining activities, and has been met with strong criticism from governments around the world.
Scientists have previously warned of 'long-lasting, irreversible ' impacts of deep sea mining on the region. Cetaceans are known to be impacted by noise pollution caused by humans, and could be impacted by the significant noise expected to be created by deep sea mining operations. These operations would also generate sediment plumes, which could further impact cetacean populations by disrupting deep ocean food systems.
Dr Kirsten Young continued, 'While more research is needed to build a complete picture of the impact of the noise and sediment plumes on cetaceans, it's clear that deep sea mining operations will negatively impact ocean ecosystems in areas far out to sea where monitoring is particularly challenging.'
The survey provides a 13-day snapshot of cetacean activity in these two deep sea mining exploration areas. Using hydrophones, the research team confirmed 74 acoustic detections of cetaceans. This included a sperm whale, Risso's dolphins and common dolphins.
Louisa Casson, Greenpeace International senior campaigner, says, 'The confirmed presence of cetaceans, including threatened sperm whales, in areas that The Metals Company is targeting for deep sea mining is yet another clear warning that this dangerous industry must never be allowed to begin commercial operations. The only sensible course of action for governments at next month's International Seabed Authority meeting is to prioritise agreeing on a global moratorium.'
Greenpeace Aotearoa deep sea mining campaigner Juressa Lee adds, 'This study again highlights why deep sea mining in the Pacific must be stopped before it gets a chance to start. Deep sea mining is just the latest colonial, extractive industry that will destroy the ocean that Indigenous Pacific Peoples depend upon for their livelihoods and to which they have close relational and ancestral ties. Pacific communities are on the frontlines of the climate crisis that they have done nothing to create. They should not be sacrificed by the false solutions being peddled by wannabe deep sea miners who will wreck their homes and livelihoods, and compromise their traditional food source.'
Calls for a moratorium on deep sea mining grew at the recent UN Ocean Conference, with four new countries joining the group supporting a moratorium, bringing the total to 37. The UN Secretary General also issued a strong call to stop this dangerous industry. Momentum against deep sea mining will now be carried forward at the July ISA meetings.

Albanese Government Must Act, CSIRO Research Fuels Calls For Deep Sea Mining Moratorium
As the peak international body on deep sea mining begins a three-week meeting, CSIRO has released a series of reports commissioned by mining proponent The Metals Company (TMC) that underscore the severe environmental risks and scientific uncertainty surrounding the dangerous industry. The findings confirm international consensus; the deep ocean is too poorly understood to proceed with deep sea mining safely or responsibly, prompting major environmental organisations to call on the Albanese Government to support a moratorium. Advertisement - scroll to continue reading The timing of the CSIRO reports appears to align with what was, until recently, TMC's plan to submit an application to the ISA on June 27 – plans the company has now abandoned in favour of a controversial U.S. based pathway via a dormant 1980s law and enabled by the Trump administration. Pressure is mounting on the Albanese Government to adopt a precautionary stance supporting a moratorium at the ISA in line with many of its major partners, including the UK, Canada, France, Germany and New Zealand. Currently, 37 countries back a deep sea mining moratorium. TMC continues to apply pressure on international regulators to accelerate approvals for this high-risk untested industry. With a state-funded agency producing research likely to be used to legitimise mining in international waters, ocean advocates are calling on the Albanese Government to direct CSIRO to take no further actions on behalf of TMC. The CSIRO reports confirm the likely damage to the seafloor and to the marine environment that civil society, Indigenous Pacific communities, and independent scientists have warned about; deep sea mining is too destructive and there is too much uncertainty to proceed. 'These findings echo the concerns we've heard right across the Pacific region – that the deep ocean is a highly complex, precious environment, and that accelerating deep sea mining would be dangerous,' said Phil McCabe, Pacific Regional Coordinator at the Deep Sea Conservation Coalition. There remains a severe lack of real-world data about deep sea ecosystems – particularly in relation to the long-term environmental impacts and the risk of toxic pollution entering the food chain. Scientists warn that many of these impacts are likely to be irreversible in human timeframes. The CSIRO reports acknowledge the potential for heavy metals to bioaccumulate in marine life, including tuna, swordfish, whales, and dolphins. 'We've seen this before; traffic light systems, digital twin technology, adaptive management systems – all designed to give the illusion of sustainable management,' said Dr. Helen Rosenbaum, Research Coordinator at the Deep Sea Mining Campaign. 'When the science is this uncertain, the only responsible signal is red.' TMC's recent decision to abandon its application to the ISA and instead issue permits through a dormant U.S. law has been widely condemned by governments and legal experts as a direct challenge to international law and multilateralism. The move undermines the ISA's authority just as states prepare to negotiate key regulations. 'Australia's credibility is on the line,' said Duncan Currie, International Lawyer and advisor to the Deep Sea Conservation Coalition. 'CSIRO's involvement with The Metals Company (TMC) risks implicating Australia in their attempt to sidestep international governance. The Albanese Government must now draw a clear line; support a moratorium at the International Seabed Authority, and ensure CSIRO takes no further action on TMC's behalf.' 'At the ISA, a moratorium or precautionary pause on deep sea mining is the only viable path to protecting the deep sea,' said Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific. 'Delegates at the ISA must listen to the science and the voices of Pacific nations and back a moratorium to stop deep sea mining before it starts.' The Deep Sea Mining Campaign, Deep Sea Conservation Coalition, Greenpeace Australia Pacific, and Surfrider Australia call on the Albanese Government to announce its support for a Moratorium at the upcoming ISA meeting in Jamaica; and direct CSIRO to take no further actions on behalf of TMC.
