The cooperative cruise of the R/V S.P. Lee in 1983 provided an excellent opportunity for a wide-range interlaboratory study on samples of crusts ground and sieved aboard the...

Beginning in 1983 the USGS searched major oceanographic institution dredge archives for samples and data relevant to the USGS Woods-Hole Ferromanganese Crust Data Base. With the...

Based on comparative studies on the utility of ICP, atomic absorption, and other techniques for the elemental analysis of geological samples the authors decided to pursue a...

During the ten R/V Hakurei-Maru cruises from 1984 through 1988 in the Northwestern Pacific island-arc area, a widespread occurrence of hydrogenetic iron-manganese crusts and...

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...

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....

During R/V T. Thompson cruise TT-192 around the the Mariana and Volcano Volcanic Arcs 60% of the dredge recoveries contained ferromanganese deposits. Substrate rocks consisted...

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...

Manganese nodules and crusts were retrieved by a Continuous Line Bucket (CLB) manganese nodule retrieval system in the Clarion-Clipperton Zone (CCZ). This system was operating...

The data encoded in the Scripps Institute of Oceanography Nodule Data Bank (SNDB) was used as a model for the publication of USGS Ferromanganese Crusts Data Bank. The chemical...

Manganese nodules and ferromanganese crusts deposited on igneous rocks from the Southern Ocean have been chemically analysed after dessication. Al, Ba, Ca, Co, Cu, Fe, Mg, Mn,...

Manganese nodules retrieved during the BENTHIFACE expedition (R/V Melville) from the Scripps Institution of Oceanography have been analysed using X-ray emission spectroscopy...
