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.

Comminution of Polymetallic Nodules with a High-Pressure Water Jet. [PDF]

Materials (Basel), 2022
This paper presents an original method for the comminution of polymetallic nodules in a hydro-jet mill of our own design, having the water jet pressure in the range of 70–200 MPa. The best comminution results are ensured by equipping the mill with a water jet having a diameter dw = 0.7 mm and a comminution-homogenization tube having a diameter dh = 2.4

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 ...

The Tubotomaculum Enigma and the Rise of Benthic Life During the Opening of the Western Mediterranean Basin. [PDF]

Geobiology
ABSTRACT Large‐scale geological processes shape microbial habitats and drive the evolution of life on Earth. During the Oligocene, convergence between Africa and Europe led to the opening of the Western Mediterranean Basin, a deep‐ocean system characterized by fluid venting, oxygen depletion, and the absence of benthic fauna.

Neanthes goodayi sp. nov. (Annelida, Nereididae), a remarkable new annelid species living inside deep-sea polymetallic nodules

European Journal of Taxonomy, 2021
A new species of abyssal Neanthes Kinberg, 1865, N. goodayi sp. nov., is described from the Clarion-Clipperton Zone in the central Pacific Ocean, a region targeted for seabed mineral exploration for polymetallic nodules.
