This paper was selected for presentation by the OTC Program Committee following review of information contained in an abstract submitted by the author(s). Contents of the paper, as presented, have not been reviewed by the ...
Morphology of an uncharted seamount from Central Indian Basin
(Elsevier, 1989)
The morphology of a seamount at 12 degrees 35'S and 76 degrees 16'E is studied. This conical seamount has a maximum height of 1275 m (water depth 4135 m) and covers an area of about 189 sq km. The maximum basal extension ...
Underwater geomorphology as a function of the variations in ferromanganese nodule characters in the Indian Ocean
(Current Science Association, 1989)
Ferromanganese nodules from three areas in the northern part of the Central Indian Ocean Basin have been studied. Statistical analysis shows significant variations in morphological and physical characters of nodules between ...
An interactive program for digitization of seabed photographs
(CSIR-NISCAIR, 1989)
A program for dignitization of seabed photographs to compute coverage and abundance of polymetallic nodules is developed. Since the objects in the seabed photograph are partially covered by thin sediment layer, the automatic ...
Statistical analysis of lineaments of Goa, India
(Current Science Association, 1989)
A study of the lineaments of Goa identified from aerial photographs is presented here. The shapes of histograms representing direction vs total number and direction vs total length have close similarities. The trended data ...
Planktonic foraminifera in waters off the Coromandel coast, Bay of Bengal
(CSIR-NISCAIR, 1989)
Use of swath data in realtime navigation by pattern recognition
(Elsevier, 1989)
A new method is proposed with the aim of reducing dead reckoning error (DRE) during multibeam echosounding survey in deep ocean. Bathymetric data is used in this method to estimate DRE in position fixing. This method can ...
Viscous dissipation effects on heat transfer in flow past a continuous moving plate
(Calcutta Mathematical Society, 1989)
The study of thermal boundary layer on taking into account the viscous dissipative heat, on a continuously moving semi-infinite flat plate is presented here.Similarity solutions are derived and the resulting equations are ...
Ore grade manganese nodules from the central Indian basin: an evaluation
(1989)
Comparative studies on manganese nodules from two different areas (S and R) in the Central Indian Basin show distinct variations in their composition, grade (percent Ni + Cu), and abundance (kg/m2), which are explained in ...
