67 samples of manganese nodules were obtained during the GH79-1 Cruise of R/V Hakurei Maru in the northern part of the Central Pacific Basin. All nodules were immersed in...

Surface sediments were collected during the GH79-1 cruise, Geological Survey of Japan, from the area of 10°-13°N and 165°-180°W. Material for this study (34 samples) was...

Sediment samples from three box cores and one piston core, collected on cruise GH79-1 of the research vessel Hakurei-Maru, were analyzed for major oxides and minor elements. All...

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...

The nodules used in this study were collected from two cruises in the western North Pacific by box coring (KH-79-4) and dredging (GH-78-1). After being dried at 110°C each...

Manganese nodules were retrieved from the Pacific Ocean during the CNEXO-NIXO campaign and the GH76 and GH80 campaigns of the R/V Hakurei-Maru. Their chemical composition was...

Chemical analyses were made on one hundred and forty five powder samples taken from defined parts of manganese nodules retrieved during the GH80-5 campaign of the R/V...

14 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using Atomic absorption spectrophotometry (AAS) From 1983...

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...

In 1974, the Geological Survey of Japan began its systematic investigation of manganese nodules in the Central Pacific Basin on the new geological research vessel Hakurei Maru....

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