The Northwest Pacific Ocean is a broad ocean influenced by two major currents: the cold Oyashio Current flowing southward and the warm Kuroshio Current flowing northward. In...

From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other...

Manganiferous materials were collected at 49 stations in the Central Pacific Basin, the Mid-Pacific Mountains, the Manihiki Plateau, and the Penrhyn Basin during cruise GH80-1....

The moisture content and the minor element contents were determined for 115 sediment samples collected from the G H 80-1 survey traverses of the Central Pacific Wake-Tahiti...

The 127 sediment samples of this study (Table XIV-1) were selected on the ship from 17 piston cores and 27 box cores, which were taken by shipboard members from 44 locations...

Fifty-seven samples of manganese nodules from the GH78-1 area were analysed in bulk rock for major and some minor metal elements to provide the data for the evaluation of the...

Seventeen chemical elements were determined for 49 samples taken from the GH78-1 cruise of the R/V Hakurei-Maru northern Central Pacific Basin. Thirty-one samples of them are...

In this study, 111 manganese nodules from the north and south Central Pacific were analyzed for total sulfur and total carbon. The samples had been collected along two tracks of...

142 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). From 1983 until...

Initial data on the hydrogen-isotopic compositions in hydrous Mn minerals from various occurrences fall in a wide range from -298 to -84 per mil, relative to SMOW. DeltaD-values...

Considerable regional variations in the chemical composition of manganese nodules from a wide range of the Pacific Ocean have been observed. These variations can be more exactly...

In 1970, the United States put forward the first detailed and comprehensive proposal for a regime which would apply to the mining of manganese nodules in the area beyond...

The cores and dredges described in this report were taken on the GH76-2 Expedition in March-May, 1976 by the Geological Survey of Japan from the R/V Hakurei Maru. A total of 47...

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...

Chemical analyses of manganese nodules from the Central Pacific Basin show that their chemical composition varies regionally, although that of the associated sediments is...

118 samples of manganese nodules obtained during the GH77-1 cruise were analyzed in bulk rock for major and some minor metal elements to provide the data for the evaluation of...

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....
