The bulk compositions of Samoan Basin nodules were determined for this study, and these data have been compiled with those of Glasby, et al. (1975) to form Appendix L. Silicon,...

Mn nodule shapes which can be described as spheroidal, ellipsoidal or polynucleate predominate in the Southwestern Pacific Ocean. The morphology, size, weight and number of...

Silicon, aluminum, calcium, titanium and iron percentages were obtained by X-ray fluorescence analysis using an EDAX International EXAM system. Sediment samples collected during...

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...

The Midpac '81 (SO18) exploration voyage with the R/V Sonne was a first step to study the regional distribution, nature and formation of Co-rich manganese crusts over submarine...

The chemical composition of ferromanganese crusts retrieved during the KK84 (R/V Kana Keoki) and L583HW (R/V S.P. Lee) was determined using methods developed by Haynes, B. W. at...

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...

Mobile laboratories are important to the exploration geochemist because they offer rapid chemical analyses of geologic materials in the field. This permits modification of the...

The average chemical metal composition of ferromanganese crusts was determined through various samples dredged during the L9-84-CP (R/V S.P. Lee) expedition by the United States...

Eighteen stations were occupied; 13 dredge hauls were collected on seamount, atoll, and island flanks and three box cores were taken from the sediment cap of an unnamed seamount...
