Circulation and geostrophic transport in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)Utilising the hydrographic data collected during the early northeast monsoon of 1983 and southwest monsoon of 1984, the circulation of waters of the Bay of Bengal and the associated volume transport have been studied in ... -
Equatorial jet - a case study
(NISCAIR, New Delhi, 1992)Detailed EOF analysis of wind data reportEd. by Wunsch over Gan (00 degrees 41'S; 73 degrees 10'E) is made for the period 1963-70. The year 1964, which exhibited least variability from mean wind structure, has been chosen ... -

Hydrography and circulation in the northwestern Bay of Bengal during the retreat of southwest monsoon
(Indian Academy of Sciences, 1992)The distribution of temperature and salinity in the upper 500 m of the northwestern Bay of Bengal, adjoining the East Coast of India, during the retreat of southwest monsoon (September) of 1983 is presented. This study ... -
A longshore sediment transport estimation for the Indian coast
(Indian Society for Physical Sciences of the Oceans, 1992)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) m super(3) to 2.0 x 10 super(6) m ... -
On the role of geometry of cross-section in generating flood-dominance in shallow estuaries
(Academic Press, 1992)Shallow estuaries often show tidal asymmetry of flood-dominance in which duration of the flood is shorter and its peak discharge larger than the corresponding values during ebb. A simple analytic model for this phenomenon ... -
A solution to the inverse problem in ocean acoustics
(DESIDOC, New Delhi, 1992)The methodology and software developed to reconstruct a vertical sound speed profile as a part of studies on the marine acoustic modelling, using the ray path lengths and the travel time perturbations in tomographic layers ... -
Multivariate autoregressive algorithms for ocean wave modelling

Ocean surface waves and winds over the north Indian Ocean from satellite altimeter - preliminary results of SAC-NIO joint project
(Indian Society for Physical Sciences of the Oceans, 1992)With the aim of retrieving, validating and mapping ocean surface winds and waves in the north Indian Ocean, GEOSAT altimeter data for the period November 1986 to October 1987 and available sea truth data for the above ... -
Acoustic waveguide characteristics of the Indian Ocean - north of equator
(PORSEC Committee, Shimizu, Japan, 1992)The acoustic characteristics of the waters of the Arabian Sea and Bay of Bengal, constituting the northern Indian Ocean, are analysed based on a climatological mean sound speed field. In the upper 30-40 m in the Bay of ... -
Energy and generating mechanism of a subsurface, cold core eddy in the Bay of Bengal
(NISCAIR, New Delhi, 1992)Computation of available potential energy (APE) of a recently observed cold core, subsurface eddy (centered at 17 degrees 40'N and 85 degrees 19'E) in the Bay of Bengal revealed that the energy maxima associated with the ... -
Seasonal distribution of wave heights off Yanam on the east coast of India
(Institution of Engineers, India, 1992)Waves were measured off Yanam on the East Coast of India for a period of one year from June 1983 to May 1984. The data were analysed using the Tucker's zero up-crossing and the spectral methods. Seasonwise distribution of ... -
Mixed layer heat budget of Kuroshio-Tango Triangle using satellite and ship observations
(PORSEC Committee, Shimizu, Japan, 1992)Using a three dimensional heat flux model, variation of heat storage in the mixed layer of a triangular oceanic area, embedded in the Kuroshio has been studied for a period of a few days in the month of November, 1983. For ... -
Does winter cooling lead to the subsurface salinity minimum off Saurashtra, India?
(Oxford and IBH, New Delhi, 1992)Cold and dry winds of the northeast monsoon cool the northern Arabian Sea during November-January. The intensity of cooling is highest in the proximity of the peninsula of Saurashtra, India. Using hydrographic data, we ... -
On the occurrence of high salinity waters off the east coast of India
(Indian Society for Physical Sciences of the Oceans, 1992)Some high salinity waters (35 x 10 super(3)) are observed in the surface layer of the western Bay of Bengal during northeast monsoon and in subsurface layer during southwest monsoon. These values are discussed on the basis ... -
