Beyond the plains: deep-sea mining of polymetallic nodules on and around seamounts

Frontiers in Marine Science
Deep-sea mining management, scientific research, and public discourse have largely focused on polymetallic nodule extraction from abyssal plains. However, there is growing commercial interest in nodules on and around seamounts, with exploration and ...

Morphological Reconstruction Based on Optical Images for the Seabed Semi-Buried Polymetallic Nodules: A Fusion Model of Elliptic Approximation and Contour Interweaving Methods

Journal of Marine Science and Engineering
Polymetallic nodules enriched in Mn, Ni, Cu, Co, and other metals may be one of the first seabed mineral resources to be exploited. Although optical imagery is crucial for resource evaluation, semi-buried nodules are frequently overlooked.

Megabenthic ecology of abyssal polymetallic nodule fields

, 2019
Abyssal polymetallic nodule fields constitute an unusual deep-sea habitat. The mix of soft sediment and the hard substratum provided by nodules increases the complexity of these environments, and is thought to promote the occurrence of some of the most biologically diverse seafloor assemblages in the abyss.
