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... -
Measured iron isotopic compositions of Fe-Mn crust sample CXD31
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... -
In-situ concentrations of iron and aluminium in CXD31 sub-samples
Iron (Fe) availability in the ocean is strongly influenced by external inputs, including atmospheric deposition, sediment dissolution, and hydrothermal fluxes. To investigate... -
Measured ¹⁰Be and ⁹Be isotopes in manganese nodules and crusts from the Pacif...
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.... -
Chemical composition of ferromanganese nodules from the Pacific Ocean
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... -
Chemical composition of ferromanganese nodules and crusts from the Pacific us...
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... -
Lead isotope ratios for manganese nodules
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... -
Tellurium analyses of 12 samples of manganese oxide nodules from the Pacific ...
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... -
Chemistry of manganese deposits from the Hawaiian Archipelago
Selected manganese deposits from the Hawaiian Archipelago were submitted to chemical analysis using two methods. Atomic absorption spectrophotometry was used for the analysis of... -
Elemental composition of ferromanganese crusts from the Hawaiian Archipelago
The paper presents the results of studies of ferromanganese deposits in the Hawaiian Archipelago. The chemical composition of ferromanganese oxide crusts and their associated... -
Chemical composition of ferromanganese crusts dredged from the Marshall Islands
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... -
Analysis of deep-sea ferromanganese nodules using flame atomic absorption and...
All the samples were air-dried, crushed, and ground to a fine particle size (<100 mesh). Flame analyses were carried out with a solution that was obtained by the digestion of... -
