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.

Journal of Marine Science and Engineering, 2022 The impeller blades will continually strike the slurry mixture inside the pump, causing deterioration and a change in particle size. In this study, the degradation of mineral particles under various cycle times, rotational speeds, and flow rates is ...

The seabed - an important mineral resource of Slovakia in the future [PDF]
Acta Montanistica Slovaca, 2015 In 1987, Slovakia bought part of the ocean bottom with the occurrence of mineral resources future - polymetallic nodules. The polymetallic nodule is a geological term for naming natural features consisting of more than 40 metals and other chemical ...

Spatial Variability of Abyssal Nitrifying Microbes in the North-Eastern Clarion-Clipperton Zone
Frontiers in Marine Science, 2021 Abyssal microbes drive biogeochemical cycles, regulate fluxes of energy and contribute to organic carbon production and remineralization. Therefore, characterizing the spatial variability of benthic microbes is important for understanding their roles in ...

Has phytodetritus processing by an abyssal soft-sediment community recovered 26 years after an experimental disturbance? [PDF]
, 2018 The potential harvest of polymetallic nodules will heavily impact the abyssal, soft sediment ecosystem by removing sediment, hard substrate, and associated fauna inside mined areas. It is therefore important to know whether the ecosystem can recover from

Simultaneous Leaching of Seafloor Massive Sulfides and Polymetallic Nodules [PDF]
Minerals, 2019 Simultaneous leaching of seafloor massive sulfides (SMS) from Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) and polymetallic nodules (PN) from Clarion Clipperton Zone (CCZ) of the Central Pacific Ocean was studied. Leaching tests were conducted using sulfuric acid and sodium chloride, at a temperature of 80 °C for 48 h under reflux.
