Geochemical analysis of manganese nodules collected from Indian ocean aboard R/V Marion Dufresne with wet chemistry. Digitized Table 2.From 1983 until 1989 NOAA-NCEI compiled...

Geochemical analysis of manganese nodules collected from Indian ocean aboard R/V Marion Dufresne with Atomic Absorption Spectrometry. Digitized Table 1.From 1983 until 1989...

Manganese nodule deposits exhibit variabity in distribution, deposit density, nodule morphology, and chemistry on scales of meters to thousands of kilometers. The Challenger...

An area 20 x 20 nautical miles, within the abyssal hill region of the northern Central Pacific, has been sampled intensively by R/V Valdivia . The sediments represent four...

The area selected for the investigations of the VA-13/2 expedition of the Valdivia corresponds to area 2 of the previous VA-08 expedition performed in 1974. Its center...

The geological characteristics and Fe-Mn deposits from the North wall of the Romanche trench (Atlantic ocean) were studied in order to investigate possible relationships of...

Accumulation rates of manganese in sediments of thirty-eight deep-sea cores range from 0.1 to 3.4 mg/cm²/ka. Manganese accumulation rates in five nodules range from 0.2 to 1.0...

The structure of the principal manganese minerals of the nodules, todorokite and birnes- site, is determined by the structure of hydrated manganese dioxide. Using this fact and...

An extensive field of iron-rich, nickel- and copper-poor manganese nodules covers the deep sea-floor of the northeastern quadrant of the Southwestern Pacific Basin, and the...

During the 1967-1968 period chemical analysis of both major and trace elements was performed on manganese nodules, crusts and micronodules on a large number of cores taken by...

The shale-normalized REE patterns of manganese nodules from the northwest Atlantic show enrichment in Sm and Eu relative to the heavier and lighter REE, excluding Ce, and are...

Attempts have been made to study the entire growth history of a manganese nodule from the northern part of Peru Basin in the Pacific using radiochemical profiles of 230Th232Th,...

We discuss the differences in chemical composition between the two opposite sides of a deep-sea manganese nodule. The upper side, facing sea water, contains a hydrogeneous...

Since 1998, approximately 148,134,806 m2 (14,813.5 Ha) of seagrass habitat has been mapped across the United Kingdom coastline. This was calculated from a total of 1,872...

Marine particulate organic carbon-13 stable isotope ratios (δ13C-POC) provide additional constraints and insights into the cycling of carbon from dissolved pools to marine...

These data contain the annual, seasonal and monthly biome partitioning of the global surface ocean on a 1° latitude x 1° longitude resolution for the ocean mixed layer. The...

Oceanic very short-lived substances (VSLSs), such as bromoform (CHBr3), contribute to stratospheric halogen loading and, thus, to ozone depletion. However, the amount, timing,...

Here we present a new set of high-resolution early Pleistocene records from the eastern equatorial Pacific (EEP). Sediment composition from Ocean Drilling Program Sites 1240 and...

Ocean surface partial pressure of CO2 (pCO2) and air-sea CO2 fluxes in the Baltic Sea estimated using self-organizing map classifications along with class-specific linear...

We supplemented the dataset presented in Luo et al. (2012) "Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates" with measurements of nifH...
