Sonardyne's Fetch Positioning Technology to Support Deepsea Neutrino Detector
A new deep-sea neutrino detector being built to transform our understanding of the universe will use precise positioning from underwater technology company Sonardyne. An array of Sonardyne's Fetch instruments will provide the precise and stable underwater positioning the 3,000 m deep Pacific Ocean Neutrino Experiment (P-ONE) needs to accurately detect and analyze high-energy neutrinos. P-ONE, a multi-national, multi-institute scientific collaborative project, will help scientists to unlock insights into extreme cosmic phenomena like black holes and supernovae. The cosmic
NOAA Ship Rainier to Map Critical Mineral Deposits in Pacific US Waters
In early April, NOAA Ship Rainier will begin to map and characterize more than 8,000 square nautical miles of federal waters off Kingman Reef and Palmyra Atoll in the Pacific Ocean. This project is part of the Department of Commerce's implementation of the U.S. Offshore Critical Minerals Mapping Plan, as described in President Trump’s Executive Order 14285: Unleashing America's Offshore Critical Minerals and Resources.Rainier is a hydrographic survey ship staffed by NOAA Corps Officers and professional mariners. The first survey leg will focus on mapping with multibeam echo sounders in

"They now have a reasonably good picture of the maritime domain they hope to operate in, either in peacetime or in war."Chinese researchers, similarly, see strategic value in their work. Zhou Chun, an Ocean University researcher who oversees the Indian and Pacific Ocean sensor arrays, was quoted last year in an Ocean University press release as saying that his work had shown him "the rapid development of my country's maritime defense and military capabilities."

NOAA Determines TMC USA’s Seabed Mining Application is in Substantial Compliance
compliance with the requirements of the Act and its implementing regulations.Earlier this year, TMC USA submitted a consolidated application for an exploration license and a commercial recovery permit for polymetallic nodules in international waters of the Clarion Clipperton Zone (CCZ) in the Pacific Ocean. The application was filed under NOAA’s new consolidated application and review process and represents the first submission of its kind.It covers a ~65,000 km2 exploration and commercial recovery area in the CCZ, compared to a commercial recovery area of ~25,000 km2 in TMC USA’s initial
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
