Deep-sea Mining Tests Resume After Robot Rescued from Pacific Ocean Floor

finalized by the International Seabed Authority, a U.N. body.Some environmentalists and companies are calling for a moratorium, saying too little is known about the environmental impact of disturbing the ocean floor, while industry analysts have questioned the economics of technically challenging deep sea mining.GSR says it will only apply for a mining contract if the science shows that the seabed can be a responsible source of the metals needed for the clean energy transition.(Reporting by Helen Reid; editing by Barbara Lewis

Mining Robot Stranded on Pacific Ocean Floor in Deep-sea Mining Trial

A seabed mining robot being tested on the Pacific Ocean floor at a depth of more than 4 km (13,000 ft) has become detached, the Belgian company running the experimental trial said on Wednesday.Global Sea Mineral Resources (GSR), the deep-sea exploratory division of dredging company DEME Group, has been trialling Patania II, a 25-tonne mining robot prototype, in its concession in the Clarion Clipperton Zone since April 20.The machine is meant to collect the potato-sized nodules rich in cobalt and other battery metals that pepper the seabed in this area, and was connected to GSR’s ship with a 5km

Environmental Groups Call on Norway to Stop Deep-sea Mining Plans

Six environmental organizations, including the World Wildlife Fund and Greenpeace, on Monday, called on Norway to stop plans to open ocean areas for deep-sea mining.The government in January launched a process to open areas on its extended continental shelf for exploring and producing minerals from the ocean floor, with plans to issue the first licenses as early as 2023."Minerals and metals for the green shift should be obtained from consumption reduction and better reuse on land, not from the depths of the sea where brutal mining can do irreparable damage to nature," the environmentalists

learning to identify useful signals, which could have obvious uses in submarine detection. Cable could also be deployed for subsurface imaging, if paired with a source, like traditional seismic data acquisition. Being able to spot where noise is coming from could be used for many applications from deep sea mining surveillance to wind farm monitoring, suggests Lindsey.It’s just the start for this technology. To help spur it on, there’s also a National Science Foundation funded DAS Research Coordination Network that’s linked researchers globally to help spur innovation and understanding

Green Minerals, Oil States Sign LoI for Deep Sea Mining System

Green Minerals AS, a recently formed subsea mineral mining company, has signed a letter of intent with a consortium led by Oil States Industries (UK) Ltd.The LoI is for collaboration on a FEED study for a turnkey Harsh Environment Deep Sea Mining System (HEDSMS) against a long term contract for exclusive use within Norwegian jurisdiction as defined by the Seabed Minerals Act of 2019."The company anticipates first ore under its planned pilot in 2026. The recovered ore is expected to contain significant grades of minerals needed for the green shift, such as copper, cobalt, nickel and rare

Kongsberg Maritime Launches new HiPAP 602 Ultra Deepwater SSBL Positioning Tool

Kongsberg Maritime (KM) launched its HiPAP 602 Ultra Deepwater SSBL (Super Short Base Line) Positioning Tool, which has been designed to provide extreme range (up to 7,000m+) and accuracy for positioning ROVs and AUVs, and to operate as a DP reference.To achieve this performance, the HiPAP 602 replaces the spherical transducer used by the HiPAP 502 with a large-diameter, multi-element planar array combined with electronic beam forming and unique signal processing techniques. This enables narrow transmitter and receiver beams to be generated in all directions within the lower half of the transducer

A Net-zero Future Depends on the Ocean’s Ability to Absorb Carbon

change. But this isn’t just a coastal story anymore.The oceans moderate the world’s climate through the absorption of heat and carbon. And just how much carbon the ocean will continue to absorb for us remains an open question. Whatever we do, it must be grounded in our growing wisdom of the deep connections between life on land and in the sea.As Canada commits to a net-zero future and plans its post-COVID economic recovery, innovations and investments could backfire if they reduce the ocean’s ability to absorb our excesses.Links between land and seaThe ocean has always directly affected
