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 ... -
Hydrographic features of the coastal waters of Kakinada
(Indian Society for Physical Sciences of the Oceans, 1992)The physical characteristics of coastal waters - temperature, salinity and currents at the surface and subsurface levels - off Kakinada in the Bay of Bengal at 4 stations (bottom depth 5, 12, 22 and 42 m) along 17 degrees ... -
Surface layer temperature inversion in the Arabian Sea during winter
(Oceanographic Society, Japan, 1992)Surface layer temperature inversion in the south eastern Arabian Sea, during winter has been studied using Bathythermograph data collected from 1132 stations. It is found that the inversion in this area is a stable seasonal ... -
Surfzone dynamics of the Konkan coast, India
(Oxford and IBH, New Delhi, 1992)The Konkan Coast has the distinct morphological features than the rest of the Indian Coast. Field studies on beach variation, littoral environmental observation and longshore sediment transport were carried out for a period ... -
Significance of oceanographic field investigations for siting coastal thermal and nuclear power plants
(Central Board of Irrigation and Power, 1992)Practical problems and some suggestions to overcome them in carrying out field observations for feasibility of setting up a power plant near coast lines are discussed -
On an upwelling front, propagation of upwelling and vertical velocity in the eastern Arabian sea during monsoon, 1987
(PORSEC Committee, Shimizu, Japan, 1992)A coastal upwelling front parallel to the coast and identifiable upto a depth of 75 m was observed between 12.5 and 16 degrees N along the eastern Arabian Sea in September, 1987 from closely spaced digital BT data. With a ... -
Advective surface velocity in the north west Pacific derived from NOAA AVHRR images
(PORSEC Committee, Shimizu, Japan, 1992)Using sequential AVHRR images in November 1983, nearsurface advective velocities are derived in the region Kuroshio south of Japan. For deriving the velocities two methods are used. One is the Method of Cross Correlation ... -
Characteristic mixing triangles in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)Temperature-salinity structures in the inner part of Bay of Bengal showed complete mixing processes in the upper bay, less than about 600 m can be characterisEd. by a mixing triangle constitutEd. by three characteristic ... -
Estimation of added-mass and damping coefficients of a tethered spherical float using potential flow theory
(Elsevier, 1992)Added-mass (alpha) and damping coefficients (beta) of a tethered spherical float, undergoing oscillatory motion in sinusoidal waves, have been derived from the motion generated velocity potential for one degree-of-freedom ... -
Coastal circulation and upwelling index along the east coast of India
(Indian Society for Physical Sciences of the Oceans, 1992)Hydrographic data collected during November-December, 1983 and July-August (1984) along sections normal to the east coast of India were analysed for salinity and temperature structures. Coastal circulation and volume ... -
Selection of site coolant intake and discharge of shore based power stations - coastal oceanographic considerations
(BARC, Bombay, 1992)Many new nuclear power plants, reactors are proposed along coastal area of Indian coastline apart from the existing ones. All these, being ultimately a heat exchange process, necessitate enormous quantity of cooling water ... -
Estimates of vertical velocities and eddy coefficients in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)Vertical velocities and eddy coefficients in the intermediate depths of the Bay of Bengal are calculated from mean hydrographic data for 300 miles-squares. The linear current density (sigma- O) versus log-depth plots show ... -
Measuring the monsoon
(Reed Business Information Ltd., 1992)Monsoons are familiar elements of tropical life, bringing rain to the crops that feed millions. The effects do not stop there, in the Arabian Sea, the twice-yearly monsoon winds enrich the fishing grounds, as well as setting ... -
Relationships between Indian summer monsoon rainfall and ice cover over selected oceanic regions
(Indian Society for Physical Sciences of the Oceans, 1992)The variations in oceanic ice cover at selected polar regions during 1973 to 1987 have been analysed in relation to the seasonal Indian summer monsoon rainfall. The ice cover over the Arctic regions in June has negative ...
