Evaporation over the Arabian Sea during two contrasting monsoons
(Springer, 1989)Monthly mean surface fields of different meteorological parameters and evaporation are studied for the 1979 (poor monsoon) and 1983 (good monsoon) monsoon seasons over the Arabian Sea, in order to understand the role of ... -
Morphology and evolution of the central west coast of India
(Indian Association for Limnology and Oceanography, 1989) -
Application of longshore transport equations to Andhra coast, East coast of India
(Elsevier, 1988)Ship-reported waves published in the Indian Daily Weather Report are compiled for a period of 16 years and are used for the estimation of the longshore transport rate. Using the two well known longshore transport equations, ... -
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 ... -
Size analyses and geochemistry of ferromanganese nodules from the Central Indian Ocean Basin
(1989)Ferromanganese nodules collected during the 13th cruise of the M.V. Skandi Surveyor in 1987 cover a very large area, 71 424 km super(2) in the Central Indian Ocean. The area consists of 13 nodule types, which are grouped ... -
Sonograph patterns of the central western continental shelf of India
(Tirunelveli: JCSONLINE, 1989)Side scan sonar and bathymetric surveys were conducted on the central western continental shelf of India. The sonographs portray a smooth, relatively featureless inner shelf, up to a depth less than 40-50 m, which is covered ... -
DDT residues in fishes from the eastern Arabian Sea
(Elsevier, 1989)Samples of Sardinella fimbriata (sardine), S. longiceps Valenciennes (Indian oil sardine), Apolectus niger (black promfret), Pampus argenteus (silver promfret) and Penaeus sp. (prawn) from the coastal Arabian Sea (location ... -
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' ... -
Grade distributions in manganese nodules of Central Indian Ocean Basin
(Current Science Association, 1989)Data concerning to geological setting physical characteristics and bulk chemical composition of the nodules sampled from CIOB were stored in the Computer Data Bank of this Institute. Bulk chemical composition of nodules, ... -
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 ... -
Increased particle flux to the deep ocean related to monsoons
(Nature Publishing Group, 1989)Monsoons cause seasonal reversals in the surface circulation of the northern Indian Ocean. In the Arabian Sea this results in the upwelling of nutrient-rich water along the coasts, making it one of the highly productive ... -
Early diagenetic processes affecting nutrients in the pore waters of Central Indian Ocean cores
(Elsevier, 1989)Pore-water nutrients, nitrite, nitrate, phosphate, silicate, pH and solid-phase organic carbon were analysed for one core from the Arabian Sea and three cores from the manganese nodule area in the Central Indian Ocean ... -
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 ... -
Ooid turbidites from the Central Western continental margin of India
(Springer, 1989)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, ... -
Geochemical evidence of terrigenous influence in deep-sea sediments upto 8°S in the Central Indian basin
(Elsevier, 1989)Thirty-two representative deep-sea sediment samples have been studied from three manganese nodule-bearing environments in the Central Indian Basin: diatomaceous-radiolarian ooze-clay, pelagic brown clay and calcareous ooze. ... -
Lack of cross-shelf transport of sediments on the western margin of India: Evidence from clay mineralogy
(Tirunelveli: JCSONLINE, 1989)The distribution of clay minerals on the inner shelf, outer shelf and in a 6 month sediment trap on the western continental shelf of India has been studied. Marked compositional differences in the inner shelf clays ... -
Precipitation of iron in windopane oyster shells by marine shell-boring cyanobacteria
(Taylor & Francis, 1989)Shells of windowpane oyster (Placuna placenta (L.)) in the intertidal zone of the Zuari Estuary, Goa, India were often found to be black in color. Microscopical observation of partially decalcified shells showed the presence ...
