Geochemical analysis of manganese nodules collected from Indian ocean aboard R/V Marion Dufresne with wet chemistry.

Geochemical analysis of manganese nodules collected from Indian ocean aboard R/V Marion Dufresne with Atomic Absorption Spectrometry.

Manganese nodule deposits exhibit variabity in distribution, deposit density, nodule morphology, and chemistry on scales of meters to thousands of kilometers. The Challenger...

The area selected for the investigations of the VA-13/2 expedition of the Valdivia corresponds to area 2 of the previous VA-08 expedition performed in 1974. Its center...

In September of 2018, the Spanish research vessel Sarmiento de Gamboa shot the seismic profile FRAME-p03 across the continent-to-ocean transition zone in the Iberia Abyssal...

The database for nitrate concentrations and nitrate δ15N includes new data and most of the measurements that have been published to date. This database also includes most of the...

The Surface Ocean CO₂ Atlas (SOCAT) version 2019 dataset (Bakker et al., 2016) is a quality-controlled dataset containing 25.7 million surface ocean gaseous CO₂ measurements...

We supplemented the dataset presented in Luo et al. (2012) "Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates" with measurements of nifH...

Sea surface salinity (SSS) is the least constrained major variable of the past (paleo) ocean but is fundamental in controlling the density of seawater and thus large-scale ocean...

The Marine Minerals Database contains geochemical analyses and auxiliary information on present-day marine deposits of primarily ferromanganese nodules and crusts. Some data for...

The geological characteristics and Fe-Mn deposits from the North wall of the Romanche trench (Atlantic ocean) were studied in order to investigate possible relationships of...

The structure of the principal manganese minerals of the nodules, todorokite and birnes- site, is determined by the structure of hydrated manganese dioxide. Using this fact and...

An extensive field of iron-rich, nickel- and copper-poor manganese nodules covers the deep sea-floor of the northeastern quadrant of the Southwestern Pacific Basin, and the...

The shale-normalized REE patterns of manganese nodules from the northwest Atlantic show enrichment in Sm and Eu relative to the heavier and lighter REE, excluding Ce, and are...

Attempts have been made to study the entire growth history of a manganese nodule from the northern part of Peru Basin in the Pacific using radiochemical profiles of 230Th232Th,...

We discuss the differences in chemical composition between the two opposite sides of a deep-sea manganese nodule. The upper side, facing sea water, contains a hydrogeneous...

The compositional variability in large igneous provinces has mainly been attributed to changes in the melting regime and shallow crus- tal processes and commonly ranges from...

The ship campaign MSM114/2 (ARC) with the German research vessel Maria S. Merian took place from 22 January to 23 February, 2023. The campaign started in Mindelo, Cape Verde,...

The ship campaign MSM114/2 (ARC) with the German research vessel Maria S. Merian took place from 22 January to 23 February, 2023. The campaign started in Mindelo, Cape Verde,...

Oceanic very short-lived substances (VSLSs), such as bromoform (CHBr3), contribute to stratospheric halogen loading and, thus, to ozone depletion. However, the amount, timing,...
