The manganese content of 4 manganese nodules was determined by atomic absorption. The decrease of total alpha activity was used to evaluate Mn accumulation. Because CaCO3 is a...

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...

Ferromanganese deposits from the North Pacific and Blake Plateau have been sampled from potential mining sites either by the industry (Deepsea Ventures, Kennecott Corporation,...

Deepsea Ventures Inc. conducted a series of assessments and tests regarding the mining of manganese nodules in the Blake Plateau area. These operations were made using the R/V...

The Deep-sea Sponge Microbiome Project is a large-scale study, integrating 16S amplicon sequencing data of seawater, sediment, and sponges, with a large set of ecological and...

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...

As a part of a continuing study of the distribution and abundance of tellurium in various materials of the earth's crust, analyses were made of 12 samples of manganese nodules...

In 1984, the U.S. Geological Survey (USGS) conducted a reconnaissance cruise L9-84-CP aboard the R/V S.P. LEE along the northern Ratak Ridge, Marshall Islands and retrieved...

A suite of three palagonites from pillowed basalts collected from within the Mid-Atlantic Ridge rift valley between 25°N and 30°N wer analysed along with another suite of two...

Chemical and mineralogical analyses of manganese nodules from a large number of widely spaced localities in the Pacific and Indian Oceans have shown that their mineralogy and...
