Mn, Fe, Zn and As speciation in a fast-growing ferromanganese marine nodule. [PDF]

, 2004
International audienceThe speciation of Mn, Fe, As and Zn in a fast-growing (0,002mm/yr), shallow-marine ferromanganese nodule has been examined by micro X-ray fluorescence, micro X-ray diffraction, and micro X-ray absorption ...

Equity Interest Scheme in Polymetallic Nodules Deep Seabed Mining: The Positives and Negatives

Jurnal Media Hukum, 2022
UNCLOS 1982 initially obliged all applicants to submit a reserved area when applying for exploration activities in the Area. Such provisions were derogated when the equity interest scheme was introduced in the exploration regulations for polymetallic ...

Understanding Mn-nodule distribution and evaluation of related deep-sea mining impacts using AUV-based hydroacoustic and optical data [PDF]

Biogeosciences, 2018
In this study, ship- and autonomous underwater vehicle (AUV)-based multibeam data from the German ferromanganese-nodule (Mn-nodule) license area in the Clarion–Clipperton Zone (CCZ; eastern Pacific) are linked to ground-truth data from optical imaging.

Mineral composition of ferromanganese nodules from the Pacific Ocean

, 2022
The manganese minerals constitutive of ferromanganese nodules retrieved during cruises of the R/V Vityaz wer determined by X-ray diffraction. The analyses were made of well crystallized microscopic areas and several X-ray analyses were made for each ...

X-ray Computed Tomography Analysis of Ferromanganese Nodule Nuclei from the Western North Pacific Ocean: Insights into Their Origins

, 2023
Ferromanganese nodule nuclei are considered crucial to the formation and distribution of nodules. However, because it is difficult and time-consuming to study ferromanganese nodule nuclei, few studies have been performed, despite the large number of ...
