Hydrographic features of the Lakshadweep (Laccadives) sea during winter
(Indian Society for Physical Sciences of the Oceans, 1992)Hydrographic features of the Lakshadweep Sea during winter have been studied using the data collected in December during the 13th cruise of R.V. Gaveshani. The mixed layer depth in this region varies between 30 and 70 m. ... -
Seasonally reversing current bands across 15 degrees N in the Arabian Sea and their implications
(NISCAIR, New Delhi, 1992)Geostrophic currents computed from hydrographic data collected in different months from a section along 15 degrees N in the Arabian Sea show alternate N-S current bands. Flow directions of these bands are found to reverse ... -
Sound-speed structure and propagational characteristics of a cold core eddy in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)An analysis of acoustic characteristics of a cold core eddy in the Bay of Bengal reveals that the eddy introduces in sound-speEd. by about 10 ms-1. The depth of deep sound channel axis beneath eddy remains constant whereas ... -
Diurnal variability of heat fluxes and heat content at a few locations off central east coast of India during April 1989
(India Meteorological Department, 1992)Diurnal variability of surface wind speed, net heat exchange, sea surface temperature, vertical thermal structure and heat content at three locations, viz., station A (17 degrees 59'N, 83 degrees 53.9'E), station B (17 ... -
Wave refraction studies off Agonda beach (Goa)
(NISCAIR, New Delhi, 1992)Analysis of wave refraction and longshore current has been carried out for a narrow strip off the shores of Agonda (Goa, India). Zones with high wave energy and rip currents have been demarcated. It is found from the ... -
Diurnal and semi-diurnal tidal currents in the deep mid-Arabian sea
(Indian Academy of Sciences, 1992)Current meter records from two depths, approximately 1000 m, at three mooring in the deep mid-Arabian Sea were used to study tidal components. Tidal ellipses for the semi-diurnal (M2, S2 and K2) and the diurnal (K1 and P1) ... -
Estimation of design wave heights based on exterme value statistics for Kakinada coast, Bay of Bengal
(NISCAIR, New Delhi, 1992)Statistical analyses for longterm distribution of significant wave heights were performed using Lognormal, Weibull, Gumbel and Fretcher distributions for waves measured off Kakinada, Andhra Pradesh, India from June 1983 ... -
Potential vorticity field in the Bay of Bengal during southwest monsoon
(Indian Society for Physical Sciences of the Oceans, 1992)The distribution of potential vorticity along potential density surfaces in the upper 500 m indicates the presence of a wind driven anticyclonic gyre between 10 degrees N and 14 degrees N in the eastern Bay during southwest ... -
Water characteristics, mixing and circulation in the Bay of Bengal during southwest monsoon
(Yale University, 1992)Influence of the freshwater influx, the wind forcing and the Indian Ocean monsoon drift current on the property distributions and the circulation in the Bay of Bengal during southwest monsoon has been quantified. At the ... -
Satellite observations of the northeast monsoon coastal current
(PORSEC Secretariat, Shimizu, Japan, 1992)Satellite Infrared observations, from Advanced Very High Resolution Radiometer (AVHRR), during November 1987-February 1988 and hydrographic data from the eastern Arabian Sea are used to describe the poleward flowing coastal ... -
Comparative study on spreading function for directional wave spectra
(Oxford and IBH, New Delhi, 1992)The planning and design of all coastal and offshore installations call for an information on wave directionality. This can be accurately obtained through the knowledge of the directional wave spectrum which is commonly ... -
Response of surface buoy moorings in steady and wave flows
(Oxford and IBH, New Delhi, 1992)A numerical model has been developed to evaluate the dynamics of surface buoy mooring systems under wave and current loading. System tension response and variation of tension in the mooring line at various depths have been ... -
Equatorward western boundary current in the Bay of Bengal during November - December 1983
(Indian Society for Physical Sciences of the Oceans, 1992)Geostrophic circulation derived from the observed hydrographic data for the period November-December (1983) indicates the presence of a strong equatorward western boundary current (WBC) in the Bay of Bengal. The curl sub(z) ... -
Sea surface temperature anomalies in the Arabian Sea
(PORSEC Secretariat, Shimizu, Japan, 1992)The sea surface temperature anomalies over the various study areas, namely, the northern, western, central, eastern and southern Arabian Sea areas have been studied for the period 1948-1972. There were about 105, 87, 92, ... -
Characteristics of coastal waters of the western Bay of Bengal during different monsoon seasons
(CSIRO, Australia, 1992)Physical characteristics of waters along the eastern coast of India up to offshore distances of 400 km have been investigated during the seasons of the north-easterly and south-westerly monsoons in light of relevant observed ... -
Estimates of run off, evaporation and precipitation for the Bay of Bengal on seasonal basis
(Indian Society for Physical Sciences of the Oceans, 1992)Mean seasonal river discharge rates (R) of the major rivers along the east coast of India, Bangla Desh and Burma; evaporation rates (E) computed for 5 degrees lat-long. Squares from data on heat loss and mean yearly ... -
Heat budget parameters for the southwestern Arabian Sea during monsoon - 88 experiment
(Oxford and IBH, New Delhi, 1992)The temporal evolution of heat budget parameters for the southwestern Arabian Sea shows that the net surface heat balance is negative (approx 70 Wm sup(-2)) in May 1988 (phase 1) mainly due to excessive latent heat loss ... -
A quality control procedure for seawater temperature data
(Indian Society for Physical Sciences of the Oceans, 1992)A three level quality check has been developed for seawater temperature data. The standards used in the procedure for the quality check are the characteristic property of vertical temperature distribution, watermass property ... -
Nearshore circulation in relation to effluent disposal off Thal, Maharashtra, west coast of India
(Indian Association for Limnology and Oceanography, 1992)Tides, currents and related field parameters at Thal, Maharashtra Coast, India, were studied to assess the environmental conditions for proper disposal of effluents from a large fertilizer factory. The tidal ranges being ...
