The composition of the acid-insoluble residue and hydrolysate fraction has been determined for manganese crusts and coatings retrieved along an equatorial Pacific transect...

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 during the KK72 (Midway 72-07-02) campaign using a CNEXO free-fall grab system. Selected samples were chemically analysed in bulk using Atomic...

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 were taken from free-fall grabs at various stations of the Manganese Nodule Program BOMDROP cruise MN75-03. The underlaying sediment was essentially a...

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

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

During a short geological cruise in May 1979 by HMAS Kimbla, two manganese nodules were recovered from the deep sea about 250 nautical miles southeast of Sydney. They were...

During the evaluation of marine mineral resources of the Kiribati region sponsored by CCOP/SOPAC program (ESCAP, United Nations) various cruises of the R/V Machias successfully...

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...

48 manganese nodules from the Pacific Ocean were selected by the authors for detailed analysis. "Bulk chemical composition" gives, unless otherwise indicated, the results of...

In the mid 1970s Kennecott Exploration, Inc. conducted various systematic studies on the chemical composition of manganese nodules and crusts in order to determine the...

The samples used for this study are a subset from almost 200 surface samples from the western Nazca plate analyzed during the IDOE Nazca Plate Project. The subset was selected...

The nodules examined were sampled during the R/V Valdivia cruises VA 04, 05, 09, 13/1, and 18. The majority of these samples was taken from a region extending from 135°w to...

Initial attempts to classify the composition of manganese nodules in the Pacific Ocean illustrated the paucity of data for the Southwestern Pacific Basin. Recent major element...

Manganese nodules and encrustations dredged during the GEORSTOM I and II cruises have been analysed for their major constituents. From 1983 until 1989 NOAA-NCEI compiled the...

For assessing their desulfuration and mineral potential, manganese rich concretions were selected from the stations of the AMC-11-67 cruise performed by ESSA (NOAA) in October...

Ferromanganese nodules at DOMES sites A, B, and C collected by the R/V Oceanographer. Nodules selected for bulk analysis were taken from the dominant size class of each box core...
