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...

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...

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...

Five manganese nodules from a range of deep-sea and fossil environments were selected for this study. Most samples were prepared for bulk analysis by grinding the material...

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

Ferromanganese nodules and encrustations have been analysed for Mn, Fe, Co, Ni, Cu, Zn, Pb, Ca and Al by atomic absorption spectrophotometry. The preparation of...

Twenty-one samples of deep-sea ferromanganese nodules collected from the Pacific, Atlantic, and Indian oceans were supplied by the Lamont-Doherty Geological Observatory of...

Iron-manganese crusts were chosen from existing collections in order to cover as wide an area and depth range as possible. Sampling was concentrated in the Central Pacific...

The study reported here involved the analysis of 12 rare earth and 13 minor elements in 13 nodules from the S.W. Pacific; 1 nodule from equatorial N. Pacific (DOMES Site C) as...

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...

Manganese nodules, coatings and crusts from the Pacific and the Indian oceans were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES)....

Iron (Fe) is a key micronutrient regulating marine productivity and the global carbon cycle, yet reconstructing the relative contributions of different Fe sources through time...

Iron (Fe) availability in the ocean is strongly influenced by external inputs, including atmospheric deposition, sediment dissolution, and hydrothermal fluxes. To investigate...

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....

For evaluating the efficiency of high-temperature sulfation as a potential technique used in the extraction of metals from manganese nodules, the authors have chemically...

Manganese nodules were retrieved during various cruises of the R/V Vema and R/V Robert Conrad from Lamont Doherty Earth Observatory (LDEO). Their chemical composition was...

The authors have selected manganese nodules broadly representative of world oceanic areas. Approximately 1 gram of each manganese nodules was leached with 25-mi 6N HC1. Lead was...

A variety of manganese nodules from the Pacific Ocean were selected from dredge performed during various ship cruises of the Scripps Institution of Oceanography (SIO. For Mn and...
