Distribution pattern and morphochemical relationships of manganese nodules from the Central Indian Basin
In the Central Indian Basin manganese nodule abundance was variable in all sediment types. Mean abundance varied from 1.5 in calcareous ooze to 10.2 kg/m sup(2) in terrigenous-siliceous ooze sediments. Nodule grade and ...
Characterizing Indian Ocean manganese nodule-bearing seafloor using multi-beam angular backscatter
Application of quantitative angular backscatter modelling to manganese nodule-bearing areas of the Central Indian Ocean Basin (CIOB) has been initiated at NIO during the year 1998. Studies were aimed to establish the ...
