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 ...

Equity Interest Scheme in Polymetallic Nodules Deep Seabed Mining: The Positives and Negatives

Jurnal Media Hukum, 2022
UNCLOS 1982 initially obliged all applicants to submit a reserved area when applying for exploration activities in the Area. Such provisions were derogated when the equity interest scheme was introduced in the exploration regulations for polymetallic ...

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 ...

Subsea Nodule Recognition and Deployment Detection Method Based on Improved YOLOv8s

IEEE Access
An improved small-target detection model based on YOLOv8s is proposed to address the challenges associated with deep-sea polymetallic nodule detection, such as complex target shapes, small sizes, and strong environmental interference.

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.

The influence of habitat heterogeneity and disturbance on benthic community structure in deep-sea polymetallic nodule environments and management implications for seabed mining

Frontiers in Marine Science
Habitat heterogeneity is known to influence faunal community structure, but its influence on deep-sea benthic communities remains understudied, particularly for polymetallic nodule environments in abyssal waters.

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.
