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 ...

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.

Ferromanganese nodules and micro-hardgrounds associated with the Cadiz Contourite Channel (NE Atlantic): Palaeoenvironmental records of fluid venting and bottom currents [PDF]

, 2012
Ferromanganese nodule fields and hardgrounds have recently been discovered in the Cadiz Contourite Channel in the Gulf of Cadiz (850–1000 m). This channel is part of a large contourite depositional system generated by the Mediterranean Outflow Water ...

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, Volume 247, Issue 6, Page 1109-1130, December 2025.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

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.

Millennial‐Scale Hydrothermal Variability at the Carlsberg Ridge Driven by Sea‐Level Change and Transient Magmatism

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Hydrothermal systems at mid‐ocean ridges (MORs) mediate the transfer of heat and geochemical fluxes from the mantle to the hydrosphere, facilitating fluid‐rock interaction and metal cycling. While short‐term hydrothermal dynamics are well studied, the long‐term response of these systems at slow‐spreading ridges to glacial‐interglacial sea ...
