Biodiversity and Habitat – What does the data tell us?
TMC says sediment stirred up by mining mostly resettles nearby. More than 95% resettles within 1-2 km of the collector vehicle.
Biodiversity and Habitat – What does the data tell us?
TMC presented survey data on CCZ seafloor biodiversity and recovery. Foraminifera recolonized disturbed seafloor, reaching 30% density within a year.

Innovation at Depth
TMC says its new collector disturbs seafloor far less than old design. Post-pass surveys found just a few cm of disturbance versus 80 cm before.
Noise & Light – What does the data tell us?
Hydrophone data mapped noise levels around a seabed mining vessel. Noise above 120 decibels reaches 3.6 km; light reaches only 20-30 meters.
Innovation at Depth – Go with the Flow: Mine Planning to Reduce Impact
TMC mapped how sediment plumes follow seabed contours downslope. Sweep mining now covers 500 to 1,000 meters instead of 80 to 100 km runs.
Innovation at Depth – Midwater Release: Less Up, Less Down
TMC's system adds a hydrocyclone step to filter fine sediment. Sediment returns at 2,000 meters depth, below the top 1,000 meters where most biomass lives.
NOAA Determines TMC USA’s Consolidated Deep-Seabed Mining Application is in Substantial Compliance
NOAA found TMC USA's consolidated deep-seabed mining application, covering about 65,000 km2, in substantial compliance.
