Assessing benthic community structure and diversity in the Western Pacific polymetallic nodule area: insights from multi-primer eDNA metabarcoding

open access: yesFrontiers in Marine Science
IntroductionDeep-sea polymetallic nodules are considered a critical resource for meeting future global metal demands. However, current knowledge of benthic community composition and biodiversity patterns in these regions remains limited, impeding ...

Foundational guiding principles for a flourishing Earth system

open access: yesBusiness and Society Review, Volume 130, Issue S1, Page S34-S52, Spring 2025.
Abstract In this perspectives article, we maintain that the current local to global sustainable development predicaments we face are the result of humanity's impact on the Earth System (ES)—that is to say, on the very systemic fabric of the ES (i.e., its functioning and configuration), combined with an insufficiently coherent application of sustainable

Probabilistic ecological risk assessment for deep‐sea mining: A Bayesian network for Chatham Rise, Pacific Ocean

open access: yesEcological Applications, Volume 35, Issue 1, January 2025.
Abstract Increasing interest in seabed resource use in the ocean is introducing new pressures on deep‐sea environments, the ecological impacts of which need to be evaluated carefully. The complexity of these ecosystems and the lack of comprehensive data pose significant challenges to predicting potential impacts.

Ecological and Economic Prerequisites for the Extraction of Solid Minerals from the Bottom of the Arctic Seas

open access: yesE3S Web of Conferences, 2017
The world ocean has huge reserves of minerals that are contained directly in the water, as well as on the surface of its bottom and in its subsoils. The deposits of solid minerals on the surface of the bottom of the World Ocean are considered the most ...

Numerical Study and Parameter Optimization of a Dual-jet Based Large Particle Collection System for Deep-sea Mining [PDF]

open access: yesJournal of Applied Fluid Mechanics
A dual-jet collecting device is highly efficient at picking up small-sized polymetallic nodules; however, its performance is not as effective for large nodules in deep-sea mining.

Marine Metallic Mineral Resources of the Pacific Basin [PDF]

open access: yes
In the 1970s and 1980s, the ocean became a focus of attention for mineral producers and consumers. This paper surveys that trend with particular emphasis on several specific metals and types of resource deposit.

The Stability of Manganese Oxides Under Laser Irradiation During Raman Analyses: I. Compact Versus Channel Structures

open access: yesJournal of Raman Spectroscopy, Volume 56, Issue 1, Page 95-112, January 2025.
Mn oxides are important geomaterials widely used in various technological applications. In this work, we present our results on the behaviour of the most common Mn oxides having compact and channel structures during laser irradiation. We show that the spinel structure of hausmannite is the final degradation product of all these compounds.
