Geology and geochemistry of ferromanganese nodules in the Japanese Exclusive Economic Zone around Minamitorishima Island

GEOCHEMICAL JOURNAL, 2016
A dense field of ferromanganese (Fe-Mn) nodules was discovered on a seamount approximately 300 km east of Minamitorishima Island, in the Japanese Exclusive Economic Zone. To evaluate its potential as a resource for critical metals, we describe results of

Osteopontin stabilization and collagen containment slows amorphous calcium phosphate transformation during human aortic valve leaflet calcification [PDF]

Scientific Reports
Calcification of aortic valve leaflets is a growing mortality threat for the 18 million human lives claimed globally each year by heart disease. Extensive research has focused on the cellular and molecular pathophysiology associated with calcification ...

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

, 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.

Dr John Grant Malcolmson and a reconciliation of the Middle Devonian Lethen Bar and Lethen House fish bearing nodule localities

Scottish Journal of Geology, 2023
The area known as Lethen Bar and Clune, SE of Nairn, Scotland, is a classic Middle Devonian locality which has yielded nodules or concretions, some of which contain fossil fishes with the highest quality of preservation.

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 ...

Silica diagenesis promotes early primary hydrocarbon migration

Geology, 2020
We present evidence that hydrocarbon source rocks can be preconditioned for primary hydrocarbon migration at an early stage of catagenesis by pore-scale processes linked to silica diagenesis.

An assessment of bottom current controlled sedimentation in Pacific Ocean abyssal environments [PDF]

, 2018
The effect of the circulation of polar-sourced dense waters on the deep seafloor is still largely unknown. This paper presents multibeam bathymetric evidence for the existence of present-day contourite drifts on the central Pacific ocean at depths ...
