Wave transmission prediction of multilayer floating breakwater using neural network
(IIT; Madras, 2009)In the present study, an artificial neural network method has been applied for wave transmission prediction of multilayer floating breakwater. Two neural network models are constructed based on the parameters which influence ... -
Methods of gas hydrate concentration estimation with field examples
(Society of Petroleum Geophysicists, India, 2009)The presence of gas hydrates alters the bulk physical properties of the host sediments. The deviation of the physical property in the hydrated layer from the regional (hydrate-free background) trend can be used to estimate ... -

Management of ports and maritime trade of Orissa and Andhra Pradesh during the historical period
(Indian Society for Prehistoric and Quaternary Studies, 2009)Along the 7516 km long coastline of India, several ports and trade centres have existed from ancient times. Among them, the ports and trade centres of Orissa and Andhra Pradesh played a significant role in diffusing Indian ... -
New evidence of marine archaeology around Mul Dwarka (Kodinar), Gujarat coast, India
(Indian Society for Prehistoric and Quaternary Studies, 2009)Marine archaeological explorations were carried out in and around Mul Dwarka (Kodinar) on the Saurshtra coast. The oldest remains are attributed to the Harappan phase at Kanjetar and Kaj. Both sites are situated close to ... -
Mapping of Environmental Sensitive Index (ESI) for the oil spills at Goa coast, India
(IIT Bombay, 2009)Indian remote sensing satellite (IRS) data have been used to find out the Environmental Sensitivity Index (ESI) for the Goa coast which is situated in the west coast of India. It is one of the most sensitive environments ... -
Seasonal variations and trophic ecology of microzooplankton in the southeastern Arabian Sea
(Elsevier, 2010)The seasonal ecological response of microzooplankton in the southeastern Arabian Sea is presented. During the spring intermonsoon period, stratification and depletion of nitrate in the surface waters (nitracline was at 60 ... -
Air-sea gas transfer in a shallow, flowing and coastal environment estimated by dissolved inorganic carbon and dissolved oxygen analyses
(The Oceanographic Society of Japan, 2010)We estimated gas exchange rates in Kabira Reef at Ishigaki Island, southwest Japan, using a mass balance calculation with dual ‘biological’ tracers: dissolved inorganic carbon (DIC) and dissolved oxygen (DO). The nighttime ... -
Distribution of butyltins in waters and sediments of the Mandovi and Zuari estuaries, west coast of India
(Springer, 2010)Butyltins (TBT, DBT, MBT) were measured in water and sediment samples collected from various locations in the Mandovi (ten stations) and Zuari (nine stations) estuaries, Goa, India, during November 2007. The total butyltin ... -
Dynamic loadings of deepwater spar palatform - A case study
(Surathkal: National Inst of Ocean Technology, 2007)Various wave loadings are considered separately on the deepwater Spar platform, with the wave propagation along x-axis and dynamic analyses are carried out at 1150m water depth using Newmark- beta approach The dynamic ... -
Diurnal variability of heat fluxes over the coastal waters off Visakhapatnam during post-monsoon and winter seasons
(NISCAIR, CSIR, 2010)Diurnal variability of heat fluxes in the coastal waters of Visakhapatnam has been studied during post-monsoon (Oct, 2006) and winter (Jan-Feb, 2007) seasons utilizing the surface meteorological data and radiation measurements ... -
Changes in the occurrance of hard substratum fauna: A case study from Mumbai harbour, India
(NISCAIR, CSIR, 2010)Intensive sampling was carried out in the marine environment of Mumbai and Jawaharlal Nehru ports to investigate the composition of benthic sessile population on three different occasions during 2001 to 2002. This study ... -
