Dredge spoil disposal off Kavaratti Island, Lakshadweep, India
(NISCAIR, CSIR, 1996)Maintenance dredging has been carried out along the navigational channel at Kavaratii Island and dredge spoil is disposed in the open sea. This paper describes the movement of sediment plume while dredging and disposal. ... -
Richardson Number, stability and turbulence- A coherent view
(NISCAIR, CSIR, 1996)As turbulence in water is governed by vertical mobility controlled by static stability and horizontal mobility controlled by currents, the Richardson Number should give a measure of turbulence also. It is argued in this ... -
Diagnostic model of 3-D circulation in the Arabian Sea and western equatorial Indian Ocean: Results of monthly mean sea surface topography
(Indian National Science Academy, 1996)A three-dimensional diagnostic model has been developed to compute the monthly mean circulation and sea surface topography in the Western Tropical Indian Ocean north of 20 degrees S and west of 80 degrees E. The diagnostic ... -
Surface circulation off Somalia and western equatorial Indian Ocean during summer monsoon of 1988 from Geosat altimeter data
(Taylor and Francis, 1996)The sea level variability derived from repeating tracks of the Geosat altimeter data during the late phase (August-September) of the summer monsoon of 1988 revealed the presence of multiple meso-scale eddy features with ... -
Mixed layer depth and thermocline climatology of the Arabian Sea and western equatorial Indian Ocean
(NISCAIR, CSIR, 1996)A band of zonally oriented ridge of mixed layer depth and thermocline base extending from African Coast to the Central Indian Ocean is observed between 5 degrees S and 10 degrees S throughout hte year. Mixed layer depth ... -
Directional wave spectra off southeast coast of Tamil Nadu
(Allied, Chennai (India), 1996)Knowledge on directional wave parameter is important for the design of any coastal structure and estimation of nearshore sediment tansport. The desired degree of detail may vary from the information on predominant wave ... -
Physical oceanography of the Bay of Bengal and Andaman Sea
(George Allen and Unwin. London, UK, 1996)Physical oceanography of the Bay of Bengal and Andaman Sea is reviewed for the first time. All available information for over 50 years is consolidated in this review. To begin with, information on peripheral or related ... -
Arabian Sea upwelling - A comparison between coastal and open ocean regions
(Current Science Association, Bangalore, India, 1996)The response of the eastern Arabian Sea to prevailing winds during an upwelling event, in the peak of southwest monsoon, was studied at both coastal and open ocean environment based on the data collected as a part of the ... -
Wave effects on a pressure sensor
(Allied, Chennai (India), 1996)Wave flume experiments indicated that for waves propagating on quiescent waters the sensor's performance improved (i.e. the difference Delta P between the average hydrostatic and measured pressures was small and positive) ... -
Mechanism of the biological response to winter cooling in the northeastern Arabian Sea
(Macmillan, 1996)The Arabian Sea is one of the most biologically productive ocean regions, mainly due to the upwelling of nutrients during the summer (southwest) monsoon. But the northern Arabian Sea continues to sustain fairly high ... -
Dynamics of the east India coastal current. 2. Numerical solutions
(American Geophysical Union, 1996)A linear, continuously stratified model is used to investigate the dynamics of the East India Coastal Current (EICC). Solutions are found numerically in a basin that resembles the Indian Ocean basin north of 29 degrees S, ... -
Wind fields of storms from surface isobars for wave hindcasting
(Allied, Chennai (India), 1996)Marine operations of various types are critically linked to mean and extreme wave statistics. In the Indian seas extreme wave conditions are caused by cyclones and steady strong monsoon winds. Wave data from cyclone areas ... -
Forcing mechanisms of the Bay of Bengal circulation
(Current Science Association, Bangalore, India, 1996)A state-of-the-art ocean general circulation model, set up for the North Indian Ocean and driven by climatological wind stress simulates most of the observed features of the near-surface circulation of the Bay of Bengal. ... -
Dynamics of the east India coastal current. 1. Analytic solutions forced by interior Ekman pumping and local alongshore winds
(American Geophysical Union, 1996) -
Transport and potential vorticity in the Bay of Bengal during the southwest monsoon
(Andhra University, Visakhapatnam (India), 1996)In the Bay of Bengal, the water transport and potential vorticity (PV) during the southwest monsoon are examined through the prevailing thermohaline and wind-driven circulation. The Indian Monsoon Current (IMC) and the ... -
Wave directional spectrum from array measurements
(Allied, Chennai (India), 1996)Using the method of Esteva (1976, 1977), whcih assumes that at the frequency band the waves approach from just a single "mean" wave direction, wave direction has been consistently, accurately and unambiguously evaluated ... -
Studies on waste field dilution in the vicinity of a marine outfall off Bombay
(Kalpana Corporation, 1996)Results are obtained using dimensional analysis to describe the characteristics of waste field at the marine outfall site off Bombay with a thrust on intermediate scale dispersion processes, which are of relevance to the ... -
Physical aspects of estuarine pollution - A case study in Amba river estuary
(Kamla-Raj Enterprises, Delhi, India, 1996)Tide dominated Amba river estuary was studied to evaluate it's physical characteristics with a point on application to locate a suitable release point of industrial effluents. It is important to site the outfall in a manner ... -
T-S variability and volume transport in the central Bay of Bengal during southwest monsoon
(NISCAIR, CSIR, 1996)The variability of temperature and salinity along 11 degrees N and 12 degrees N sections in the Bay of Bengal during southwest monsoon months (July-September) was found to be large in the upper 200 m west of 83 degrees E ...
