Potential impacts of polymetallic nodule removal on deep-sea meiofauna [PDF]
Scientific Reports, 2021 Deep seabed mining is potentially imminent in the Clarion Clipperton Fracture Zone (CCFZ; northeast Pacific). Seabed collectors will remove polymetallic nodules and the surrounding surface sediments, both inhabited by meiofauna, along their path.

Bacterial contributions to the formation of polymetallic nodules in the Pacific Ocean
Frontiers in Marine SciencePolymetallic nodules, widely distributed in the deep seafloor of the Pacific Ocean, are characterized by their abundance of diverse metal elements and considerable economic value. Previous studies have suggested a partial biogenic origin of these nodules.

Thorium-234 as a tracer for deep-sea mining sediment plume deposition [PDF]
Nature CommunicationsDeep-sea mining for polymetallic nodules is currently exploratory, but commercial-scale operations require indicators of environmental change to support regulatory thresholds and inform adaptive management.

Restoration experiments in polymetallic nodule areas. [PDF]
Integr Environ Assess Manag, 2022 Abstract Deep-seabed polymetallic nodule mining can have multiple adverse effects on benthic communities, such as permanent loss of habitat by removal of nodules and habitat modification of sediments. One tool to manage biodiversity risks is the mitigation hierarchy, including avoidance, minimization of impacts, rehabilitation and/or ...

Studies on Analysis Conditions of Specific Surface Area of Polymetallic Nodules
Yankuang ceshi, 2021 BACKGROUND Polymetallic nodules are predominant in deep sea sedimentary mineral resources due to the enrichment of many critical metals. Polymetallic nodules are loose and porous, which is the critical material feature that contributes the adsorption of ...

Threatened by mining, polymetallic nodules are required to preserve abyssal epifauna. [PDF]
Sci Rep, 2016 AbstractPolymetallic nodule mining at abyssal depths in the Clarion Clipperton Fracture Zone (Eastern Central Pacific) will impact one of the most remote and least known environments on Earth. Since vast areas are being targeted by concession holders for future mining, large-scale effects of these activities are expected.
