Manganese-Cycling Microbial Communities Inside Deep-Sea Manganese Nodules
TL;DR: It is shown that polymetallic nodules provide a suitable habitat for prokaryotes with an abundant and diverse proKaryotic community dominated by nodule-specific Mn(IV)-reducing and Mn(II)-oxidizing bacteria.

TL;DR: In this paper, the authors investigated the diagenetic processes altering the chemical and mineralogical composition of buried nodules in the eastern Clarion-Clipperton Zone (CCZ) down to a sediment depth of around 10m and assessed the influence of these processes on sediment geochemistry.

Hydrogenetic, Diagenetic and Hydrothermal Processes Forming Ferromanganese Crusts in the Canary Island Seamounts and Their Influence in the Metal Recovery Rate with Hydrometallurgical Methods

TL;DR: In this article, four pure hydrogenetic, mixed hydrogenetic-diagenetic and hydrogenetichydrothermal Fe-Mn Crusts from the Canary Islands Seamount Province have been studied by Micro X-Ray Diffraction, Raman and Fourier-transform infrared spectroscopy together with high resolution Electron Probe Micro Analyzer and Laser Ablation Inductively Coupled Plasma Mass Spectrometry in order to find the correlation of mineralogy and geochemistry with the three genetic processes and their influence in the metal recovery rate using an hydrometallurgical

Widespread seawater circulation in 18–22 Ma oceanic crust: Impact on heat flow and sediment geochemistry
Thomas Kuhn,Gerard J M Versteegh,Heinrich Villinger,Ingrid Dohrmann,Christina Heller,Andrea Koschinsky,Norbert Kaul,S. Ritter,S. Ritter,Anna V. Wegorzewski,Sabine Kasten +10 more
TL;DR: In this article, the authors demonstrate widespread and efficient ventilation of the 18-22 Ma oceanic crust of the northeast equatorial Pacific Ocean using heat-flow measurements, seismic mapping, and sediment pore-water analysis.
