Deep-sea mining tests produce persistent sediment plumes
Key Questions
What damage has been confirmed from deep-sea mining sediment plumes?
A 50-year review by Glover/NHM/NOC confirms irreversible damage from persistent sediment plumes. UniLodz research on 24 new CCZ amphipods shows a 37% loss in abundance due to mining impacts.
How is the US accelerating deep-sea mining permits?
Trump's executive order speeds up US permits, with BOEM and NOAA fast-tracking processes. Nine firms are joining the rush for seabed minerals.
What is the status of the RV11000 research vessel?
Inkfish ordered the $810M RV11000, with construction by Fincantieri's Vard subsidiary between Romania and Norway. The vessel will support deep-sea exploration and monitoring.
What new deep-sea species were discovered in 2026?
Taxonomists named at least eight new animal species from the deep sea in the first half of 2026, including amphipods and other crustaceans placed on new branches of life. A new species Caeconyx papso honors ocean research efforts.
What legal concerns exist around Allseas' deep-sea mining contract?
A Greenpeace-backed analysis states that Allseas' contract for The Metals Company violates UNCLOS. Related videos and reports highlight potential UN law breaches in operations.
What happened with the OOI monitoring system reversal?
The Senate blocked OOI dismantling, with NSF planning redeployment of moorings despite some already being pulled. This provides a positive development for ocean monitoring amid National Academies statements.
What does the USGS Samoa Basin report reveal?
The USGS report provides primary data from box core samples of polymetallic nodules in American Samoa. It targets deep-sea minerals and supports ongoing mapping projects.
Why is there debate over deep-sea mining's value?
Policy analyses like 'Deep-Sea Gamble' argue the deep sea may be better protected and studied before mining proceeds. The World Ocean Assessment highlights major knowledge gaps on impacts.
Glover/NHM/NOC 50-year review confirms irreversible damage; UniLodz 24 new CCZ amphipods show 37% abundance loss. Trump's EO accelerates US permits; BOEM/NOAA fast-tracking. Nine firms join rush. EIB rules out financing. Greenpeace Arctic expedition to Banana Hole. Deep Sea Minerals cleared NOAA compliance. Inkfish's $810M RV11000 ordered. OOI dismantling now reversed—Senate blocked removal, NSF plans redeploy, but some moorings already pulled. National Academies statement and EU OceanEye $92M budget provide counterweight. Trump opens Pacific MPAs to fishing. World Ocean Assessment underscores knowledge gap. First-ever goblin shark footage and range expansion. Glomar Minerals plans refinery. Canada's OceanEye response. Today's articles add historical/policy analysis, new RV11000 details, Arctic deep-sea mining crossroads, ROV attack video, Allseas UNCLOS violation legal analysis, giant isopod discovery, July deadline video, and 'Deep-Sea Gamble' policy analysis. USGS Samoa Basin box coring report provides primary data. OOI reversal is a major positive for monitoring.
