Foundational guiding principles for a flourishing Earth system
Business 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

Ecological 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.

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

Subsea Nodule Recognition and Deployment Detection Method Based on Improved YOLOv8s
IEEE AccessAn 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.

Deep bottom currents, sedimentary hiatuses and polymetallic nodules [PDF]
, 1975 Recent studies undertaken by the Centre National pour l'Exploitation des Oceans have focused some attention on the environment of nickel- and copper-bearing iron-manganese nodules in the Tuamotu Archipelago region of the South Pacific. The results indicate that the distribution of the nodules is closely linked to that of deep currents in the area.

A Review of Plume Research in the Collection Process of Deep-Sea Polymetallic Nodules
WaterThe plumes generated during the collection of polymetallic nodules in the deep sea may have a significant impact on the marine ecosystem. Therefore, this article reviews the progress in deep-sea mining and monitoring technologies related to plumes. It is
