Deep-sea mining tests produce persistent sediment plumes
Key Questions
What are the effects of sediment plumes from deep-sea mining tests?
Tests show persistent plumes that reduce amphipod abundance by 37% in the CCZ, with impacts on thousands of species. New research confirms risks to vents and seamounts including potential extinctions.
How many new ocean species were discovered in the Ocean Census?
The Ocean Census identified 1,121 new species, including glass castle worms, deep ghost sharks, and Coral Sea chimaeras. These discoveries highlight biodiversity at risk from mining activities.
What is President Trump's executive order on deep-sea mining?
The order accelerates US permits for companies like Odyssey and Impossible Metals, spawning nine new firms and fast-tracking rules via BOEM and NOAA. It raises concerns over VME and plume risks to predators.
Which companies are planning deep-sea mining operations and their timelines?
The Metals Company (TMC) targets Q1 2026 while Allseas aims for Q4 2027. Japan is also deploying REE vessels amid international regulatory debates involving NOAA, BOEM, and the ISA.
What is the 50-year review conclusion on deep-sea mining at vents and seamounts?
The review states no further research is needed and confirms clear extinction risks to species from mining activities. It draws on decades of experimental data showing severe environmental impacts.
How does the High Seas Treaty relate to small island developing states and mining?
SIDS are tying treaty negotiations to concerns over deep-sea extraction impacts. This connects biodiversity protection with economic and social risks from mining operations.
What role does eDNA play in recent deep-sea discoveries?
Falkor expeditions using eDNA identified over 40 new species plus colossal squid and dark oxygen findings. These tools reveal hidden biodiversity in mining-targeted zones.
What tensions exist between US agencies and the ISA on deep-sea mining?
NOAA and BOEM are fast-tracking permits while clashing with ISA regulations on environmental standards. This accelerates domestic efforts amid global debates on plume and habitat risks.
Glover/NHM/NOC + UniLodz 24 new CCZ amphipods confirm plumes slash 37% abundance/6-8k spp; TMC Q1'26/Allseas Q4'27; Japan REE vessel; NOAA/BOEM vs ISA; Falkor eDNA 40+ new spp/colossal squid + dark oxygen. Trump's EO accelerates US permits (Odyssey, Impossible Metals); BOEM/NOAA fast-tracking raises VME/plume risks to predators. Ocean Census 1,121 new species incl. Coral Sea chimaeras and deep ghost sharks at risk from extraction; SIDS/High Seas Treaty ties. 50-year review concludes clear extinction risk at vents/seamounts. New: Trump EO spawns nine firms and fast-tracked rules, with Vescovo skepticism on economics.
