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...

The Amazon River is known as a region of intense biochemical reactivity. As a result of increased anthropogenic impacts in its catchment (e.g. population growth, agriculture and...

Selected manganese nodules both from deep-sea environments of the Pacific Ocean and epicontinental near-shore areas (Canada west coast and Baltic Sea) have been studied to...

The dataset contains core incubation macronutrient (nitrate+nitrite, nitrite, ammonium, phosphate) concentration measurements, obtained from seven sediment cores collected from...

The dataset contains pore water macronutrient (nitrate+nitrite, nitrite, ammonium, phosphate) concentration measurements, obtained from seven sediment cores collected from the...

Scoriaceous Mn crust fragments on travertine-like nontronite deposit were retrieved near two hydrothermal vents while surveying the rift valley of the Mid-Atlantic Ridge using...

Manganese nodules and crusts samples analyzed in this work were chosen to represent a range of marine environments both oceanic and epicontinental. They were analysed by...

Manganese nodules dredged in the Indian Ocean by R/V Marion Dufresne have been selected in conjunction with cores taken in their vicinity. Most of these samples are spherical or...

Cores retrieved in the Indian Ocean by R/V Marion Dufresne have been selected in conjunction with manganese nodules dredged in their vicinity. A sample was taken for each ore...

During Valdivia cruise VA 13/2 dredging brought exceptionnally thick Mn crusts on top of basalt. One of these deposits is 22 cm thick and consists of three main zones and...

Sediment samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and minor element...

Oceanic manganese nodules samples were obtained from the Scripps Institution of Oceanography. They were subsamples of the powdered material used for studies of the major and...

103 nodule samples from each station of the GH81-4 survey from R/V Hakurei Maru were split; one half for microscopy on polished sections and one half for X-ray diffraction (XRD)...

Local variability of manganese nodule facies and associated sediments were studied around abyssal hills (60 x 60 km²) located in the equatorial zone of the Central Pacific...

The paper presents the results of studies of ferromanganese deposits in the Hawaiian Archipelago. The chemical composition of ferromanganese oxide crusts and their associated...

The expedition "RISEPAC" in 1961 of Scripps Institution of Oceanography crossed the East Pacific Rise at about 12-14°S between 90° and 140 °W, securing heat flow measurements...

Dry bulk densities, organic carbon content, organic nitrogen content and the C:N-ratio of surface sediments were determined on 27 box cores from the shallow North Sea . The box...

Sediment samples were taken during May 2017 on research vessel (R/V) Meteor (M137) at four stations (74, 128, 243, and 752 m) along the 12º S depth transect traversing the...
