Accurate Identification Method of Small-Size Polymetallic Nodules Based on Seafloor Hyperspectral Data

Journal of Marine Science and Engineering
Polymetallic nodules are spherical or ellipsoidal mineral aggregates formed naturally in deep-sea environments. They contain a variety of metallic elements and are important solid mineral resources on the seabed.

Depression chains in seafloor of contrasting morphology, Atacama Trench margin: a comment on Marsh et al. (2018) [PDF]

Royal Society Open Science, 2019
This comment presents acoustic and visual data showing deep seafloor depression chains similar to those reported in Marsh et al. (R. Soc. open sci. 5: 180286), though from a different deep-sea setting. Marsh et al.

Potential Short-Term Effects of Mine Tailings on Phytoplankton Assemblages in the Open Ocean

Journal of Marine Science and Engineering, 2022
The disposal of mine tailings into the marine environment is considered an essential option to secure the economic efficiency of deep-sea mining, but it might adversely affects the ecosystem.

Response to “Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance”

Global Policy, EarlyView.
ABSTRACT The policy analysis article “Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance” by Villar‐Muñoz (2026), https://doi.org/10.1111/1758‐5899.70185, addresses what the author perceives as “low‐certainty claims” in the context of deep‐sea mining and contrasts them with perceived “realistic scenarios” to argue that additional ...

Unlocking Europe's resources: the strategic potential of IOM deep sea polymetallic nodules for critical metals supply

Economics and Environment
The purpose of the paper is to investigate the potential of seabed polymetallic nodules in the Clarion-Clipperton Zone (CCZ) as a sustainable source of critical metals such as rare earth elements (REEs), cobalt, manganese, lithium and scandium.

The Paralicella Paradox: Broadly Distributed Lineages Without Clear Geographic Partitioning in Paralicella tenuipes and the Paralicella caperesca Species Complex

Zoologica Scripta, EarlyView.
ABSTRACT Abyssal environments (3000–6000 m ocean depth) are often presumed to promote broad genetic connectivity across ocean basins due to their vast spatial extent, apparent environmental homogeneity and few barriers to gene flow. While some deep‐sea taxa conform to this expectation, growing evidence shows that marked genetic structure can persist ...

Heterogeneous marine environments diversify microbial-driven polymetallic nodule formation in the South China Sea

Frontiers in Marine Science
Most studies on the genesis of polymetallic nodules suggested that nodules in the South China Sea (SCS) are hydrogenetic; however, the complexity and the heterogeneity in hydrology and geochemistry of the SCS might cause different processes of nodule ...

Metabarcoding as a Tool in Characterizing Nordic Deep‐Sea and Arctic Benthic Ecosystems

Environmental DNA, Volume 8, Issue 6, November‐December 2026.
Multi‐marker sediment eDNA metabarcoding robustly discriminates benthic habitats across the Nordic Seas and Arctic Mid‐Ocean Ridge. Complementary 18S rDNA and COI performance enhances taxonomic resolution and supports standardized integration of metabarcoding into future deep‐sea biodiversity surveys.

Anomalous oxygen concentration increases in benthic experiments from the Clarion Clipperton Zone are not related to polymetallic nodules [version 1; peer review: 2 approved, 1 not approved]

F1000Research
* Background Polymetallic nodules in the deep sea of the Clarion Clipperton zone (CCZ) have been implicated in the abiotic production of oxygen during benthic chamber respirometer experiments.
