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...

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...

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...

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...

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...

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...

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...

Manganese nodules were sampled from box cores collected at the Manganese Nodule Program (MANOP) site S (Clarion-Clipperton Fracture Zone) and site R (Murray Fracture Zone) in...

Manganese nodules and crusts were sampled from box cores collected at the Manganese Nodule Program (MANOP) site H in the Eastern Equatorial Pacific ocean. For majority of site H...

Manganese nodules and crusts were sampled from box cores collected at the Manganese Nodule Program (MANOP) site H in the Eastern Equatorial Pacific ocean. For majority of site H...

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...

The deposits from the DSDP Site 424 hole are divided into two major categories according to the relative proportions of the green clay-rich fractions and the presence of Fe-Mn...

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...

Ten large (surface area = 50-360 cm 2) manganese nodules and crusts from the Pacific, Atlantic and the Indian Oceanshave been selected for ¹⁰Be and ⁹Be isotopes evaluation....

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...

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...

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 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...

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...
