Manganese nodules research has focused on the area between the Clarion Fracture Zone to the North and the Clipperton Fracture Zone to the South where significant concentrations...

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,...

The terrains in the South China Sea were apart of the Southeast China continent, and their rift-departing process dominated the formation and evolution of the South China Sea....

Between January 3 and February 15, 1979, geoscientific investigations off Northwest Australia (Exmouth Plateau, Cuvier Abyssal Plain, Wallaby Plateau) were carried out on SONNE...

A six-week geological cruise of the West German research vessel Sonne, under the auspices of the Australian-German Science Agreement, has yielded a considerable amount of...

This report of the GH76-1 cruise mainly includes the results of the on-board observations in the survey area of the medial-eastern part of Central Pacific Basin (5 degree -10...

Manganese nodules collected from three areas (C, F, and G) on a N-S equatorial Pacific transect at 134° W by R. V. Sonne show differences in size, morphology, surface density...

This report of the GH77-1 cruise includes mainly the results of the on-board surveys and observations in the survey area of the medial-western part of Central Pacific Basin...

Sixty-eight manganese nodules from sixteen different stations and an additional two nodules were analyzed for major and some minor elements, and the chemical characteristics of...

Nodule samples obtained were described and studied on board for 1) observation of occurrence and morphology in and outside samplers, size classification, measurement of weight...

In the GH77-1 cruise, manganese nodules were obtained from 31 stations among 37 total ones. Here are reported the preliminary results of the observation mainly done on-board....

Chemical composition of manganese nodules and crust collected from the Hakurei Maru Cruise GH74-5, September-October, 1974, in the Eastern Central Pacific Basin by the...

Data comes from the NGDC database, https://www.ngdc.noaa.gov/. From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles,...

The cores and dredges described in this report were taken on the GH74-5 Expedition in September-October, 1974 by the Geological Survey of Japan from the R/V Hakurei Maru. A...

Recent studies on marine ferromanganese nodules have suggested a relationship between their growth rate and their chemical composition. The suggestion is based on the hypothesis...

Co-rich manganese crusts were retrieved during the SO33 (MIDPAC IIa) expedition of R/V Sonne. They were analysed for their chemical composition using X-ray fluorescence both on...
