(Table 5, page 626), Tin and main metal elements composition of ferromanganes...
Concentrations of tin in sea water decreased from estuarine and shelf (0.02-0.04 µg/kg) to surface Atlantic waters (0.009 µg/kg). Mean contents (ppm) in other materials... -
(Table, Page 194) Measurements of radium inside ferromanganese nodules in the...
The author studies in what state the radioactive matter exists in the sea water and in the sediments. The material dealt with in the present experiments are partly from the... -
Annotated record and Radium content of the detailed examination of manganese ...
At the date of publication the radioactivity of bottom sediments had only been published by a few authors. The radioactivity of selected characteristic ferro-manganese... -
(Table 2, Page 252) Average chemical composition of 11 manganese nodules and ...
The ability of the hydrated oxides of manganese and iron to adsorb ions from solution (scavenging) is considered in relation to some problems in marine geology, chemistry, and... -
Chemical composition of a P2O5 rich concretion from the Challenger expedition...
Among the geological discoveries of the end of the 19th century, one of the most remarkable and certainly most important from the economic point of view, is that lime phosphate... -
Manganese nodule geochemistry from the Challenger Expedition
C. W. Gümbel received nodules from J. Murray which were collected at a depth of 2740 fathoms, between Japan and the Sandwich Islands, by the "Challenger" Expedition. They were... -
Chemical composition of manganese nodules from the Challenger Expedition
The samples were dried in the air (in vacuo) and then dessicated at "red heat".From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from... -
Geochemistry of some manganese nodules
The manganese nodules occur in greater or less quantity all over the ocean-bed, and most abundantly in the Pacific. They occur in all sizes, from minute grains to masses of a...
