The moisture content and the minor element contents were determined for 115 sediment samples collected from the G H 80-1 survey traverses of the Central Pacific Wake-Tahiti...

The 127 sediment samples of this study (Table XIV-1) were selected on the ship from 17 piston cores and 27 box cores, which were taken by shipboard members from 44 locations...

Ferromanganese crusts were selected from two cruises performed by R/V Moana Wave in early 1986 and 1987 within territorial waters of the Cook Islands, Kiribati, Tuvalu and...

Manganese nodules and crusts were taken from free-fall grabs at various stations of the Manganese Nodule Program BOMDROP cruise MN75-03. They were analysed using atomic...

Chemical assessment of trace metals concentrations in a selected set of manganese crusts and coatings from the Pacific Ocean. Composition has been determined by atomic...

Manganese nodules from VA13/2 cruise (R/V Valdivia) were selected for a variety of morphologies and size. They were regrouped by size class and chemically analyzed in bulk. Mn,...

Sediment cores of the Bauer Deep were obtained by standard piston-coring techniques on cruises of the R/V Atlantis II (no. 54) and R/V Chain (no. 100) of the Woods Hole...

Manganese nodules and crusts from stations of the SO06 expedition (R/V Sonne) in the Aitutaki Passage have been selected for chemical analysis of Ti, Mo and Pb using atomic...

In order to evaluate the possible influence of hydrothermal activity on Fe-Mn coatings found on the surfaces of basaltic rocks in the median part of Transform Fault "A", a few...

Sampled hydrothermal deposits from Transform fault 'A' on the Mid-Atlantic Ridge have been classified into two main categories according to the relative proportion of the black...

Manganese nodules and crusts from stations of the SO06 expedition (R/V Sonne) in the Aitutaki Passage have been selected for chemical analysis. Mn, Fe, Ni and Cu were analyzed...

Preliminary results of chemical analysis of thirteen ferro-manganese nodules dredged from the Mariana and Ogasawara regions via the KH-84-1 cruise are presented. Five Mn nodule...

Of the 26 samples collected during VA-05/1 cruise of R V Valdivia during 1972, 19 were nodules of different forms, 4 ferromanganese crusts and 3 cylindral nodules. Nodules and...

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...

A CCOP/SOPAC cruise aboard C.I.G.M.F.V. Ravakai in June 1976 found a high density manganese nodule field in the south Penrhyn Basin between Aitu-taki and Penrhyn in the Cook...

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...

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...
