Wave directional spreading at shallow and intermediate depth
(Cent. for Earth Sci. Stud., Cochin (India), 1997)Based on wave measurements carried out at shallow and intermediate water depths variation of directional spread parameter 's' is studied. A comparison of the mean wave directional and principal wave direction shows that ... -
Acoustic propagational characteristics and tomography studies of the northern Indian Ocean
(Narosa, New Delhi (India), 1997)The results of the acoustic tomographic studies carried out in five sections of the Northern Indian Ocean is given. The characteristics of the sound speed field of the northern Indian Ocean comprising of the Arabian Sea ... -
Acoustical characteristics and simulated tomographic inversion of a cold core eddy in the Bay of Bengal
(European Acoustics Association, 1997)Acoustic characteristics of a subsurface, cold core eddy observed in the Bay of Bengal during southwest monsoon period is presented based on CTD (Conductivity Temperature Depth) data from 42 stations. The effect of the ... -
Large-scale processes in the upper layers of the Indian Ocean inferred from temperature climatology
(Sears Foundation, 1997) -
Ascertaining depths for samples from hydrographic casts without CTD
(Cochin University of Science and Technology, Kochi, 1997)A fairly extensive study was conducted in the Arabian Sea in April-May 1195 to ascertain sample depths without CTD. It is shown that depths (degrees 4000 m) derived using (1) only protected thermometer data, and (2) wire ... -
Wave refraction and prediction of breaker parameters along the Kerala Coast, India
(NISCAIR, CSIR, 1997)Numerical wave refraction study for the Kerala Coast has been carried out for waves representing southwest monsoon (June-September), northest monsoon (October-February) and fair weather period (February-May). Distribution ... -
Impact of 1990-'95 ENSO/WEPO event on Indian monsoon rainfall
(NISCAIR, CSIR, 1997)The negative phase of the 1990-'95 El Nino-Southern Oscillation (ENSO) and the associated Warming of the Equatorial Pacific Ocean (WEPO) was the longest observed in the 113 years of its recorded history, compared to its ... -
Killer storms from the seas
(NISCAIR, CSIR, 1997)The author has discussed the distruction taking place due to cyclone in the Indian subcontinent of formation which is said to be the result of thermal fronts in the atmosphere and sea interaction of different air masses ... -
Numerical modelling of tides and tidal currents in the Gulf of Kutch
(Cent. for Earth Sci. Stud., Cochin (India), 1997)An application of a two-dimensional tidal model to study the tidal regime in the Gulf of Kutch is made. This is with a view to synthesise various information on tides and currents that are available in the Gulf. A comparison ... -
Numerical experimentation of a diagnostic model of 3-D circulation in the Arabian Sea
(NISCAIR, CSIR, 1997)Climatic circulation in the upper levels of the Arabian Sea and western equatorial Indian Ocean are computed using a 3-dimensional, 33 level diagnostic circulation model. A steady state solution is obtained within 30 days ... -
Influence of the monsoon trough on air-sea interaction in the head of the Bay of Bengal during the southwest monsoon of 1990 (monsoon trough boundary layer experiment - 90)
(Kluwer, 1997)The analysis of 3-hourly time-series data on surface meteorological parameters collected at 20 degrees N, 89 degrees E in the head of the Bay of Bengal during the southwest monsoon period (18 August - 19 Spetember) of 1990 ... -
RIP current zones along beaches in Goa, west coast of India
(American Society of Civil Engineers, 1997)Goa has a 125-km-long coastline of which two-thirds consists of beautiful sandy beaches. There are mainly 17 beaches having significant importance of tourism. Sporadically, surf drownings have been reported at a few stretches ... -
Parametric modelling of nonstationary platform deck motions
(Cent. for Earth Sci. Stud., Cochin (India), 1997)Univariate system identification models are, in general, developed based on teh assumption that offshore dynamic systems are stationary random processes. For nonstationary processes, a method is adopted to transform the ... -
Coastal circulations driven by river outflow in a variable-density 1.5-layer model
(American Geophysical Union, 1997)A variable-density, 1.5-layer model is used to investigate the dynamics of the fresher-water plumes generated by river outflow. Solutions are found in a north-south channel, and the transport M sub(tau) and salinity S ... -
Results are coming in from JGOFS-India cruises and collaborative projects in the Arabian Sea
(U.S. JGOFS Scientific Steering Committee, 1997)This is a brief report of the Indian National Programmke for the Joint Global Ocean Flux Study (JGOFS-India). This programme involves researchers and modelers. Four laboratories are responsible for field laboratory measurement ... -

Marine data and information management system for the Indian Ocean
(Allied, New Delhi (India), 1997)The user friendly computer system for the management of marine data/information has been developed for processing of physical, chemical, biological, geological and geophysical data sets with a common inventory database. ... -
Amino acids in biofilm material on aluminium panels immersed in marine waters
(Gordon and Breach, 1997)Suspended particulate matter (SPM) and the biofilm material on aluminium panels immersed in the surface waters (approx 1 m) of Dona Paula Bay over a period of 10 d were analysed for their organic carbon (OC), organic ... -
Fouling diatom community with reference to substratum variability in tropical marine environment
(US Office of Naval Research, 1997)Diatoms are the earliest autotrophic colonizers and are responsible for the major input of energy in the form of reduced carbon to the surfce. However, information regarding the population structure of diatoms in theearly ... -
