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 ...

Giant, highly diverse protists in the abyssal Pacific: vulnerability to impacts from seabed mining and potential for recovery

Communicative & Integrative Biology, 2020
Xenophyophores, giant deep-sea agglutinated foraminifera, dominate the benthic megafauna in the eastern equatorial Pacific Clarion-Clipperton Zone. This abyssal (>4000 m depth) region hosts major deposits of polymetallic nodules targeted for future ...

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

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.

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, Volume 15, Issue 46, December 9, 2025.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Limited Spatial and Temporal Variability in Meiofauna and Nematode Communities at Distant but Environmentally Similar Sites in an Area of Interest for Deep-Sea Mining

Frontiers in Marine Science, 2017
To be able to adequately assess potential environmental impacts of deep-sea polymetallic nodule mining, the establishment of a proper environmental baseline, incorporating both spatial and temporal variability, is essential.

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

Experimental seabed disturbance effects on Chatham Rise deep‐sea meiofaunal communities, Southwest Pacific

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 ...

Effects of experimental in situ seabed disturbance on deep‐sea macrofaunal communities of Chatham Rise, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1422-1459, December 2025.
ABSTRACT With the possibility of deep‐sea mining of mineral resources occurring, it is necessary to understand potential impacts on benthic communities. Previous simulated mining experiments revealed direct benthic impacts; however, indirect impacts of sedimentation are not well understood.
