A look at the changing environment along the Indian coasts
Desai, B.N.; Das, V.K. (BARC, Bombay, 1992)Increased human activity along the Indian coastline has exerted pressure on its morphology and ecology. The factors responsible for morphological changes like subsidence, rising sea level, storms, storm surges, sediment ... -
BOD-DO modeling and water quality analysis of a waste water outfall off Kochi, west coast of India
Babu, M.T.; Das, V.K.; Vethamony, P. (Elsevier, 2006)Water quality scenarios around an offshore outfall off Kochi were simulated using MIKE21 water quality model, assuming a high Biochemical Oxygen Demand (BOD=50 mgl sup(-1)) effluent discharge. The discharge is introduced ... -
Circulation and Water Characteristics on Isanosteric surfaces in the Northern Arabian Sea during February-April
Das, V.K.; Gouveia, A.D.; Varma, K.K. (CSIR-NISCAIR, 1980)Distribution of water characteristics and circulation were studied on 260, 160, 140, 120 and 80 cl/t surfaces using isanosteric analysis and geostrophic computation The circulation pattern consisted of several eddies and ... -
Directional wave measurements and modelling
Anand, N.M.; Nayak, B.U.; Bhat, S.S.; SanilKumar, V. (New Delhi: Publications and Information Directorate, 1994)Some of the results obtained from analysis of the monsoon directional wave data measured over 4 years in shallow waters off the west coast of India are presented. The directional spectrum computed from the time series data ... -
Estimation of salinity power potential in India
Das, V.K.; RamaRaju, D.V. (Indian Association for Limnology and Oceanography, 1986)Salinity gradient as a source of energy has much potential, but this has been recognized only recently. The energy density of this source is equivalent to about 250 m water head for a salinity difference of 35 ppt. This ... -
Exploring the seas - The National Institute of Oceanography's venture
Das, V.K.; Desai, B.N. (Current Science Association, 1990) -
Geochemistry of surficial sediments along the central southwest coast of India - Seasonal changes in regional distribution
Balachandran, K.K.; Joseph, T.; Nair, M.; Sankaranarayanan, V.N.; Das, V.K.; Sheeba, P. (Coastal Education and Reserch Foundation, 2003)The coastal sediments (129 samples) of central- southwest coast of India, in and around Cochin, the second biggest industrial city along the west coast of India, were analyzed for their textural and geochemical fractions ... -
Harmonic tidal analysis at a few stations using the least squares method
Fernandes, A.A.; Das, V.K.; Bahulayan, N. (Indian Association for Limnology and Oceanography, 1991)Using the least squares method, harmonic analysis has been performed on hourly water level records of 29 days at several stations depicting different types of non-tidal noise. For a tidal record at Mormugao, which was free ... -
Hydrographic features of the Lakshadweep (Laccadives) sea during winter
Das, V.K. (Indian Society for Physical Sciences of the Oceans, 1992)Hydrographic features of the Lakshadweep Sea during winter have been studied using the data collected in December during the 13th cruise of R.V. Gaveshani. The mixed layer depth in this region varies between 30 and 70 m. ... -
Light transmission characteristics of the Northern Arabian Sea during December-May

Multibeam mapping of the exclusive economic zone of India
Nair, R.R.; Rao, P.S.; Kodagali, V.N. (New Delhi: Publications and Information Directorate, 1994)The seabed in the Exclusive Economic Zone (EEZ) of India is covered with a variety of minerals of economic interest. High resolution bathymetric maps are needed for effective utilisation and management of these resources. ... -
