An interactive program for digitization of seabed photographs
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
Use of swath data in realtime navigation by pattern recognition
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
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 ...
Basalt microlapilli in deep sea sediments of Indian Ocean in the vicinity of Vityaz fracture zone
(Geological Society of India, 1989)
Two cores recovered from the flanks of Mid-India oceanic ridge in the vicinity of Vityaz fracture zone consist of discrete pyroclastic layers at various depths. These layers are composed of coarse-grained, angular basaltic ...
Distribution of longshore sediment transport along the Indian coast based on empirical model
(Surathkal: KREC, 1989)
An empirical sediment transport model has been developed based on longshore energy flux equation. Study indicates that annual gross sediment transport rate is high (1.5 x 10 super(6) cubic meters to 2.0 x 10 super(6) cubic ...
Ooid turbidites from the Central Western continental margin of India
Gravity displaced debris flows/turbidites have been observed in five box cores collected between water depths of 649 and 3,627 m from the Central Western continental margin of India. Studies on grain size, carbonate content, ...
