MacArtney Closes a Strong Year, Prepared for Continued Demand
several significant development initiatives and customer‑driven projects completed during the year. These projects demonstrate how MacArtney’s engineering and workshop capabilities, along with close customer collaboration, translate into practical solutions for complex projects.For the Pacific Ocean Neutrino Experiment (P-ONE) off the coast of Vancouver Island, MacArtney engineered a one-kilometer subsea string that distributes power and data to 20 optical modules arranged in 50-meter sections. Designed for installation at a depth of 2,700 meters, the system is built to withstand 325 bar
The Metals Co Seeks International Deep Sea Mining Permit Under New Process
company hopes to obtain its permit by the end of the year, Barron said.London-listed miner and commodity trader Glencore has agreed to buy metals TMC extracts from the seabed.Under the new guidelines, The Metals Co resubmitted an application it had filed last April to operate in part of the Pacific Ocean between Hawaii and Mexico known as the Clarion-Clipperton Zone.The company said two zones that The Metals Co has applied to operate in contain an estimated 800 million metric tons of rocks known as polymetallic nodules filled with critical minerals including nickel, copper, cobalt and manganese
Study: Low Sulfur Fuel Reduces Lightning, May Increase Temperatures
.“Due to the 2020 emission regulation imposed by the International Maritime Organization, we observed a decrease in sulfur emissions from ships after 2020,” he said. “With less sulfate aerosol emitted from ships, we observed darker clouds over the North Atlantic Ocean and the Pacific Ocean. Because clouds become darker, they absorb more solar radiation. Our previous studies imply that the decrease in shipping sulfate aerosols could be responsible for the record-breaking global warming temperatures in 2023 and 2024.”Jin said his future research will aim to better understand
Deep Ocean Landers Help Scientists Explore Dark Oxygen Mystery
salt water to create electricity, whether there’s a biochemical process at work, or another, as yet unknown factor is at play.The Nippon Foundation’s funding includes construction of the world-first landers. The landers will be submerged in the Clarion Clipperton Zone (CCZ) in the central Pacific Ocean in the spring, with initial results expected later this year. IOC UNESCO has endorsed the project as a UN Ocean Decade activity.The research team will submerge the landers, along with a device known as an Aquatic Eddy Covariance (AEC) lander, which will measure the ‘flux’ of oxygen
A Project Called Azorian: Doing the Impossible
More than fifty years ago in March 1968 the US Navy observed a massive Soviet naval and air search in the North Pacific Ocean. The USN monitored the search over the next few months and concluded the Russians lost a submarine and were unable to find her. Using acoustic records from listening stations in the Pacific, the Navy discovered an explosive event that occurred just before and in the same area where the Soviet’s were looking. The Navy deployed a specially equipped spy submarine to secretly search the seabed where the event occurred and found and photographed the wreckage of the Russian
New Deep-Sea Coral Found on Nodules Targeted for Mining
interest for deep-seabed mining.The coral, Deltocyathus zoemetallicus – now described in a new study published in the “Zoological Journal of the Linnean Society” – was found more than 4,000 meters below the surface in the Clarion–Clipperton Zone (CCZ) of the Pacific Ocean. This is the first known hard-coral species to live directly on these nodules.The nodules grow extremely slowly – only a few millimeters over thousands of years. If mining were to remove them, this newly discovered species could lose its only known habitat – potentially before we
Deep-sea Mining Threatens “Twilight Zone” Ecosystem
are consumed by fish, seabirds and marine mammals. Zooplankton’s exposure to junk food sediment has the potential to disrupt the entire food web.”The study examined the content and effects of mining waste released during a 2022 mining trial in the midwater CCZ, an expansive area of the Pacific Ocean targeted for the extraction of deep-sea polymetallic nodules, which contain critical minerals, including cobalt, nickel and copper. Researchers collected and tested water samples from depths where the mining waste was discharged, finding that these particles had far lower concentrations
India Signs Deepsea Mining Exploration Deal with International Seabed Authority

Bahrain Sponsors Impossible Metals Deep Sea Mining Permit Application
;Seabed Authority, becoming the first Middle Eastern country to throw its support behind the fledgling industry as part of an economic diversification push.Privately-held Impossible Metals last Friday filed a 170-page application with the Jamaica-based ISA for a permit to mine part of the Pacific Ocean known as the Clarion-Clipperton Zone that contains polymetallic nodules filled with manganese, copper, nickel and other building blocks of electric vehicles and electronics.Any country can allow mining in its territorial waters. The United Nations-backed ISA was authorized by a 1980s treaty to
