Inorganic combined nitrogen budget of the Arabian Sea: Some geochemical and climatic implications
(Waseda University, Tokyo, 1992)Estimates of the local sources and sinks of inorganic combined nitrogen in the Arabian Sea suggest a net loss of sup(-)3 x 10 sup(13) gN y sup(-1). This seems to be made up largely by the upward flux facilitatEd. by a high ... -
Low frequency variability of the Indian Ocean from TOPEX/POSEIDON sea surface height anomalies
(NIO, Dona Paula, Goa (India), 2000)The sea surface height (SSH) anomalies derived from TOPEX/POSEIDON altimeter have been utilized to study the variability of surface circulation in the Indian Ocean during 1993-1999. The Western Bay, southeastern Arabian ... -
Models for changes in atmospheric carbon dioxide, ocean geochemistry and circulation during the late Pleistocene
(Vikas Publication, 1990)This report provides a review of various hypotheses put forward so far as to the role of the oceans in controlling the glacial-interglacial climatic cycles through controls on the atmospheric carbon dioxide. The available ... -
Monsoon oscillations of the Findlater Jet and coastal winds of India
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)Intraseasonal variability (ISV) of the Low Level Jet (LLJ) and its effects on coastal winds during the Indian summer monsoon are examined using National Centre for Environmental Prediction / National Centre for Atmospheric ... -
Near-surface circulation and kinetic energy in the tropical Indian Ocean derived from lagrangian drifters
(Yale University, 1999)Trajectories of 412 satellite-tracked drifting buoys deployed in the tropical Indian Ocean have been analyzed to document the surface circulation and kinetic energy field. Only drifters drogued at 15 m depth and having ... -
Numerical modeling of tide-induced currents in Thane Creek, west coast of India
(American Society of Civil Engineering, 2001)A 2D numerical model was applied to study tide-induced currents in the Thane Creek, Maharashtra, India. The model was forced by the tide at Apollo Bunder, calibrated with the observed tide at Pir Pau, and verified with the ... -
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 ... -
Observational evidence for remote forcing of the west India coastal current
(American Geophysical Union, 2008)Circulation in the north Indian Ocean is influenced by both local and remote wind forcing. So far, however, determining the contribution of these two forcing mechanisms at a location has been possible only in numerical ... -
Ocean bio-geophysical modeling using mixed layer-isopycnal general circulation model coupled with photosynthesis process
(Research Signpost; Trivandrum, Kerala; India, 2002)In the ocean mixed layer, phytoplanktons convert carbon dioxide into organic matter, which is accumulated into the body of phytoplankton, zooplankton, and fish communities. At the end of ocean biological food web, some ... -
Oceanography of marginal seas
(Oxford and IBH, New Delhi, 2001)The North Indian Ocean consists of three marginal seas; The Persian Gulf and the Red Sea in the west and the Andaman Sea in the east. Oceanographic features of these semi-enclosed basins have been discussed in this article. ... -
On the circulation in the Bay of Bengal during northern spring inter-monsoon (March-April 1987)
(Elsevier, 2003)Temperature and salinity data collected from the Bay of Bengal 22 March-28 April 1987 (Northern spring inter-monsoon) identified the seasonal anticyclonic gyre (ACG) at 16 degrees N, 86 degrees E characterized by warm ... -
Physical oceanography
(Oxford and IBH, New Delhi, 2001)The chapter on physical oceanography of the Indian Ocean is written keeping in mind the graduate students and researchers. It starts with a brief introduction (citing latest expeditions) followed by the coastal and near ... -
Response of the equatorial Pacific to chlorophyll pigment in a mixed layer isopycnal ocean general circulation model
(American Geophysical Union, 2001)The influence of phytoplankton on the upper ocean dynamics and thermodynamics in the equatorial Pacific is investigated using an isopycnal ocean general circulation model (OPYC) coupled with a mixed layer model and remotely ... -
Seasonal and inter-annual variability of surface circulation in the Bay of Bengal from TOPEX/Poseidon altimetry
(Elsevier, 2003)Sea-surface height anomalies (SSHA) from TOPEX/Poseidon altimeter from January 1993 to December 1997 have been analyzed to document the seasonal, intra-seasonal and inter-annual variability of surface circulation in the ... -
Sensitivity experiments with an adaptation model of circulation of western tropical Indian Ocean
(NISCAIR, CSIR, 1997)One 18-level adaptation model of circulation with a flat bottom at 900 m depth has been used to study the sensitivity of the solution to different magnitudes of eddy viscosity and diffusivity coefficients. Three numerical ... -
Surface circulation over the shelf off the east coast of India during the south west monsoon
(CSIR-NISCAIR, 1985)From the hydrographic data collected on board R V Gaveshani in the Western Bay of Bengal during August-September 1978, fields of temperature, salinity have been constructed and the probable flow regime has been deduced. ... -
Upper ocean circulation modulation by phytoplankton concentration in the Equatorial Pacific and the Indian Ocean
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)Wind patterns in the equatorial Pacific and Indian oceans are the factors that regulate the chlorophyll pigment distributions in the equatorial region of these oceans. Trade winds and coastline of the Pacific basin supports ... -
Various approaches to the modelling of large scale 3-dimensional circulation in the Ocean
(NISCAIR, CSIR, 1998)In this paper, the three different approaches to the modelling of large scale 3-dimensional flow in the ocean such as the diagnostic, semi-diagnostic (adaptation) and the prognostic are discussed in detail. Three-dimensional ... -
