An observation of distribution features of cobalt rich manganese deposits
Yamazaki, T.; Tsurusaki, K.; Handa, K.; Tomishima, Y.; Sharma, R. (Japan Shipbuilding Industry Foundation, 1994)Evaluation of seafloor stereo photographs, video data, and large diameter gravity core samples shows a variety of surface features associated with the crusts, nodules, and sediments covering mid Pacific seamounts. A set ... -
Distribution characteristics of co-rich manganese deposits on a seamount in the central Pacific Ocean
Yamazaki, T.; Sharma, R. (Taylor & Francis, 1998)Distribution characteristics of cobalt-rich manganese deposits were evaluated from stereo photographs and video data on a seamount in the central Pacific Ocean by image analysis, photogrammetric technique, and visual ... -
Estimation of sediment properties during benthic impact experiments
Yamazaki, T.; Sharma, R. (Taylor and Francis, 2001)Sediment properties, such as water content and density, have been used to estimate the dry and wet weights, as well as the volume of sediment recovered and discharged, during benthic impact experiments conducted in the ... -
Evaluation of Co-rich manganese deposits by image analysis and photogrammetric techniques
Yamazaki, T.; Sharma, R.; Tsurusaki, K. (Osaka: International Society of Offshore and Polar Engineers, 1994)Stereo-seabed photographs of Co-rich manganese deposits on a mid-Pacific seamount, were analysed using an image analysis software for coverage estimation and size classification of nodules, and a photogrammetric software ... -
Influence of distribution characteristics and associated seabed features on exploitation of cobalt-rich manganese deposits
Yamazaki, T.; Sharma, R.; Tsurusaki, K. (Int. Soc. Offshore and Polar Eng., Japan, 1995)Method of exploitation, selection of mine site and desing of mining system of cobalt-rich manganese deposits on seamounts would be greatly influenced by the distribution characteristics as well as the associated seabed ... -
Microtopographic analysis of cobalt-rich manganese deposits on a mid-Pacific seamount
Yamazaki, T.; Sharma, R.; Tsurusaki, K. (Taylor and Francis, 1994)Evaluation of stereo photographs and video data shows a variety of surface features associated with the crusts and nodules across a mid-pacific seamount. The differences in the coverage, distribution and relief are used ... -
Morphological features of Co-rich manganese deposits and their relation to seabed slopes
Yamazaki, T.; Sharma, R. (Taylor and Francis, 2000)The morphological features associated with Co-rich manganese deposits, the size variations of nodules, and the occurrence of different substrates have been analyzed, to evaluate the influence of various seabed slope angles ...
