Seasonal and diurnal variability of thermal structure in the coastal waters off Visakhapatnam
(Indian Academy of Sciences, Bangalore, 1987)Seasonal and diurnal variability of thermal structure in the coastal waters off Visakhapatnam has been examined in relation to the flow field and surface winds utilizing the hourly data of temperature and currents taken ... -
Seasonal and inter-annual sea surface height variations of the northern Indian Ocean from the TOPEX/POSEIDON altimeter
(NISCAIR, CSIR, 1998)The seasonal and inter-annual variability of the northern Indian Ocean was studied by analysing 10-day snapshots of sea surface height (SSH) data from TOPEX/POSEIDON altimeter for the period November 1992 to August 1995. ... -
Seasonal sea surface temperature contrast between the Holocene and last glacial period in the western Arabian Sea (Ocean Drilling Project Site 723A): Modulated by monsoon upwelling
(AGU, 2005)Annual, summer, and winter sea surface temperatures (SSTs) in the western Arabian Sea were reconstructed through the last 22 kyr using artificial neural networks (ANNs) based on quantitative analyses of planktic foraminifera. ... -
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 ... -
The Arabian Sea: Physical environment, zooplankton and myctophid abundance
(Council of Scientific and Industrial Research, New Delhi, 1999)The Arabian Sea is one of the most productive regions of the world oceans. This productivity mainly results from coastal and open ocean upwelling in summer and cooling effects during winter. Earlier and more recent studies ... -
The influence of some hydrographical factors on the fisheries of Cochin area
(National Institute of Sciences of India, 1968)From the seasonal changes in the hydrographical features of Cochin area during the year 1965-66, it is possible to deduce that a shore-ward influx of upwelled water occurs from about June to October The effect of this water ... -
The Lowering of Sea Surface Temperature in the East Central Arabian Sea Associated with a Cyclone
(Indian Association for Limnology and Oceanography, 1983)An analysis of thermal Structure in the East Central Arabian Sea associated with a moderate cyclone is presented. The heat storage and the heat budget components have been computed. Under the influence of the cyclone the ... -
Thermal response of upper layers of Bay of Bengal to forcing of a severe cyclonic storm: A case study
(NISCAIR, New Delhi, 1993)Upper ocean response to forcing of a severe cyclonic storm during May 1990 in the western Bay of Bengal was studied using the XBT data sets collected (4 d after passage of storm) under Indian TOGA programme. A maximum ... -
Thermal structure of the Western Indian Ocean during the southwest monsoon, 1983
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1993)The thermal structure and the variability of heat content of the upper 400 m of the Western Indian Ocean were examined using the expendable bathythermograph (XBT) data collected onboard RV Sagar Kanya during July-August, ... -
Thermohaline forcing of eastern boundary currents: With application to the circulation off the west coast of Australia
(Ingenta Connect Publication, 1986)The linear, viscid, continuously stratified model of McCreary (1981) is extended to allow for thermohaline forcing by a specified, longitudinally independent, surface density field @ips@@. When the ocean is unbounded and ... -
Time and space variations of monsoonal upwelling along the west and east coasts of India
(Pergamon, 1999)The study of monthly mean local temperature anomaley (LTA defined as the difference between coastal and mid-ocean sea surface temperature), and Ekman transport along the west and east coasts of India based on 60-year data ... -
Upper ocean physical processes in the Tropical Indian Ocean
(National Institute of Oceanography, Goa, 2005)This monograph is the outcome of an attempt by the authors to present a synthesis of the studies on physical processes in the Tropical Indian Ocean (TIO) in relation to air-sea interaction, monsoon/climate variability and ... -
Upwelling along the east coast of India
(National Institute of Sciences of India, 1968)An examination of the physical characteristics of the shelf waters off Karaikal in the premonsoon period and off Madras and Waltair in the premonsoon and monsoon periods reveals the presence of upwelling along the East ... -
Upwelling and sinking along Visakhapatnam coast
(CSIR-NISCAIR, 1986)Stability and stratification of the water over the shelf disappear as cold saline waters characteristic of 60 m depth rise to the surface during March. Tilting of isopycnals and offshore displacement of isohalines suggest ... -
Variability of the oceanic boundary layer characteristics in the Northern Bay of Bengal during MONTBLEX-90
(Indian Academy of Sciences, Bangalore, India, 1996)Variability of the ocean surface boundary layer characteristics on daily time-scale is studied utilizing the 3-hourly hydrographic data collected at a stationary location (20 degrees N, 89 degrees E) in the Bay of Bengal ... -
What drives the increased phytoplankton biomass in the Arabian Sea?
(Current Science Association, 2010)The seasonal variability of phytoplankton biomass in the Arabian Sea, though a well researched topic, its inter-annual variability is less explored and understood. Analysis of the satellite-derived chlorophyll pigment ... -
Zooplankton Biomass and Composition in the Western Bay of Bengal during late SW Monsoon
(CSIR-NISCAIR, 1980)Copepoda formed the predominant group except in the southern region where a swarm of pelagic tunicates reduced their contribution to only 19% of the total zooplankton count. Decapod larvae occurred in fairly large numbers ... -
Zooplankton Composition and Diversity in Western Bay of Bengal
(Cambridge University Press, 1981)The biomass of zooplankton ranged from 1-90 ml/100 m3 in the western Bay of Bengal from off Sri Lanka to south of Calcutta in June 1978. The coastal belt between Madras and Visakhapatnam where upwelling is known to occur ...
