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 ...
Larvae of Crossorhombus valde-rostratus (Alcock) and C. azureus (Alcock) (Heterostomata: Pisces) collected during the International Indian Ocean Expedition and Naga Expedition
(Marine Biological Association of India, 1989)
Larvae of Crossorhombus valde-rostratus (Alcock) and C. azureus (Alcock) containing post-flexion stages ranging in size from 6.0 mm to 12.9 mm SL and 7.5 mm to 18.8 mm SL respectively were found in the zooplankton collected ...
Effect of sediment-water interface 'boundary layer' on exposure of nodules and their abundance: a study from seabed photos
(Geological Society of India, 1989)
The results obtained from seabed photos and boomerang grab samples reveal a striking similarity in distribution patterns of size classes of polymetallic nodules. Due to partial sediment cover, there is a 'fractionation' ...
