A finite element simulation of tidal circulation in the Gulf of Kutch, India
(Elsevier, 2003)A finite element (fe) model using the software package ADCTRC was developed to simulate the tides and currents in the Gulf of Kutch, located on the northwest coast of India. The surface elevations from the model were ... -
A multi-level adaptation model of circulation for the western Indian Ocean
(John Wiley, 1999)A three-dimensional, fully non-linear semi-diagnostic (adaptation) model is described. This model is used to compute the climatological mean circulation and to understand the role of local, steady forcing of the wind and ... -
A semi-diagnostic calculation of climatic circulation in the western Indian Ocean
(NISCAIR, CSIR, 1997)A 3-dimensional, semi-diagnostic circulation model is used to compute the climatic circulation in the upper levels of western tropical Indian Ocean (20 degrees S-30 degrees N and 35 degrees E-80 degrees E) during the ... -
Acoustic remote sensing of ocean flows
(Narosa, New Delhi (India), 1997)Acoustic techniques have become powerful tools for measurement of ocean circulation mainly because of the ability of acoustic signals to travel long distances in water, and the inherently non-invasive nature of measurement. ... -
Chlorophyll modulation of sea surface temperature in the Arabian Sea in a mixed-layer isopycnal general circulation model
(American Geophysical Union, 2000)Remotely sensed chlorophyll pigment concentrations from the Coastal Zone Color Scanner (CZCS) are used to estimate biological heating rate and investigate the biological modulation of the sea surface temperature (SST) in ... -
Circulation and Distribution of some Hydrographical Properties during the late Winter in the Bay of Bengal
(Indian Association for Limnology and Oceanography, 1981)Charts showing dynamic topography, mass distribution, temperature, salinity, dissolved oxygen and inorganic phosphate in the upper layers of the Bay of Bengal for the late winter period were analysed and presented. The ... -
Circulation and Water Characteristics on Isanosteric surfaces in the Northern Arabian Sea during February-April
(CSIR-NISCAIR, 1980)Distribution of water characteristics and circulation were studied on 260, 160, 140, 120 and 80 cl/t surfaces using isanosteric analysis and geostrophic computation The circulation pattern consisted of several eddies and ... -
Circulation and water masses of the Arabian Sea
(Indian Academy of Sciences, Bangalore, 1994)The circulation in the coastal region off Oman is driven mainly by local winds and there is no remotely driven western boundary current. Local wind-driving is also important to the coastal circulation off western India ... -
Computation of large scale currents in the Arabian Sea during winter using a semi-diagnostic model
(Indian National Science Academy, 1997)A 3-dimensional, semi-diagnostic model with 331 levels in the vertical has been used for the computation of climatic circulation in the western tropical Indian Ocean. Model is driven with the seasonal mean data on wind ... -
Coupling between SW monsoon-related surface and deep ocean processes as discerned from continuous particle flux measurements and correlated satellite data
(American Geophysical Union, 1996)Particle flux data obtained by time series sediment traps deployed at water depths of approximately 3000 m in the western, central, and eastern Arabian Sea since 1986 were compared with wind speeds derived from measurements ... -
Delta sup(14)C, sigma CO sub(2) salinity of the western Indian Ocean deep waters: Spatial and temporal variations
(American Geophysical Union, 1999)Indian Ocean Deep waters (IDW) show an increase in salinity and sigma CO sub(2) between 64 degrees S and 16 plus or minus 4 degrees N by 0.106-0.110 ppt and 82-104 mu M kg sup(-1) respectively with a corresponding decrease ... -
Determination of vertical velocities in the equatorial part of the western Indian Ocean
(CSIR-NISCAIR, 1985)Using steady state two-dimensional turbulent diffusion equations of salt and heat some important characteristics of vertical circulation in the equatorial part of the Indian Ocean have been evaluated and discussed. Upwelling ... -
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 ... -
Differences in heat budgets of the near-surface Arabian Sea and Bay of Bengal: Implications for the summer monsoon
(American Geophysical Union, 2002)An analysis of the heat budgets of the near-surface Arabian Sea and Bay of Bengal shows significant differences between them during the summer monsoon (June-September). In the Arabian Sea the winds associated with the ... -
Drifting and meandering of Olive Ridley Sea turtles in the Bay of Bengal: Role of oceanic Rossby waves
(Taylor & Francis, 2009)Olive Ridley turtles in the Bay of Bengal are previously thought to migrate southward from their nesting ground, along the east coast of India (Orissa coast), towards Sri Lanka. Surprisingly, three of the four Platform ... -
Dynamics and thermodynamics of the Indian Ocean warm pool in a high-resolution global general circulation model
(Elsevier, 2005)The time evolution of the Indian Ocean warm pool, studied using a global high-resolution general circulation model, shows strong seasonality. The warm pool has the largest spatial extent during April-May, and least in ... -
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. ... -
