Micro-Tomographic Investigation of a North-Western Pacific Polymetallic Nodule
QuaternaryMicro-computed tomography (μCT) and X-ray Fluorescence (XRF) were used to investigate a Polymetallic Nodule (PN) from the North-Western Pacific abyssal plain to gather more information concerning the environmental changes that could be reflected by the ...

Rethinking Sustainable Batteries
Advanced Energy Materials, Volume 15, Issue 47, December 16, 2025.This perspective examines sustainability across the entire battery lifecycle, from mining and manufacturing to use and end of life. Twelve principles for ‘green’ batteries are outlined, and it is argued that joint industrial, academic, and policy efforts are essential to building a truly sustainable energy future. Abstract Batteries will play a pivotal

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1388-1421, December 2025.ABSTRACT Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately ...

Ultra-microbes are the minerogenetic constructors of oceanic polymetallic nodules
Chinese Science Bulletin, 1997 Polymetallic nodules (mangnese nodules) are a typical kind of manganese oncdites. The distribution of smooth surface and knobbly mangaree nodules is cloyely related to the geological background of the mine field. A systematic study on their inner laminae structure and features suggests that they are the products of millions of years reproduction and ...

Study on Travel Path Planning of Deep-Sea Nodule Collector During Collection Operation
Haiyang Kaifa yu guanliPolymetallic nodules are a current focus in the development of deep-sea mineral resources. The mining process requires nodule collectors to travel over large areas on the seafloor for nodule harvesting, and the travel path has significant impacts on both
