Altimeter-derived flow field over a newly identified coastal ocean boundary in the eastern Arabian Sea
(NIO, Dona Paula, Goa (India), 2000)A hitherto unknown coastal ocean dynamic boundary has been identified from hydrographic and TOPEX/Poseidon (T/P) altimeter data in the eastern Arabian Sea recently (Antony et al., 2000). This boundary, with a width of about ... -
Longshore currents and sediment trnsport along Kannirajapuram Coast, Tamilnadu, India
(Coastal Research Foundation, 2000)The objective of the study was to estimate longshore current and sediment transport from measured wave data and from the observations on the littoral environment. A directional wave rider buoy was deployed at 12m water ... -
Seasonal variability of upper-layer geostrophic transport in the tropical Indian Ocean during 1992-1996 along TOGA-I XBT tracklines
(Pergamon, 2000)Upper layer (0-400 m) geostrophic volume transport associated with the major current systems of the tropical Indian Ocean along the near-meridional TOGA-India XBT tracklines from Mumbai to Mauritius during 1992-1996 is ... -
Effect of vertical stability and circulation on the depth of the chlorophyll maximum in the Bay of Bengal during May-June, 1996
(Pergamon, 2000)A two-gyre circulation system consisting of an anticyclonic gyre (ACG) in the northwestern Bay of Bengal and a cyclonic gyre (CG) west of the Andaman Islands is shown by the hydrographic data collected during May-June, ... -
Aerosol properties over the Arabian Sea during the north east monsoon
(Indian Meteorological Society, Chennai (India), 2000)Knowledge of the variations of the aerosol properties is essential for the development of the satellite atmospheric correction algorithms. The measurements were carried-out during a cruise using a six channel spectral sun ... -

Pigment patterns in the Arabian Sea: Spatio-temporal variability as observed by ADEOS
(NIO, Dona Paula, Goa (India), 2000)The spatial and temporal variations of the near-surface concentration of phytoplankton pigment observed by ADEOS during November 1996 - May 1997 are studied in relation to SST and winds. Monthly composite images from OCTS ... -
An ENSO beginning in the year 2000?
(NIO, Dona Paula, Goa (India), 2000)Several models have been developed over the last few decades to predict the advent of new ENSO events several months in advance of the actual event. None of the models have predicted a warm event beginning by the year 2000. ... -
Upwelling and associated hydrography along the west coast of india during southwest monsoon, 1999
(NIO, Dona Paula, Goa (India), 2000)During May 1999 twenty-five hydrographic stations were carried out covering the waters of the west coast of India from 8 degrees N to 13 degrees N as a part of Marine Research - Living Resources (MR-LR) programme. The ... -
Surface layer temperature inversion in the Bay of Bengal
(NIO, Dona Paula, Goa (India), 2000)Hydrographic and XBT data archived in the Indian Oceanographic Data Centre (IODC) are used to understand the process of temperature inversions occurring in the Bay of Bengal. The following aspects of the inversions are ... -
Directional spectrum of ocean waves from array measurements using phase/time/path difference methods
(Pergamon, 2000)Wave direction has for the first time been consistently, accurately and unambiguously evaluated from array measurements using the phase/time/path difference (PTPD) methods of Esteva in case of polygonal arrays and Borgman ... -
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 ... -
Seasonal cyclogenesis and the role of near-surface stratified layer in the Bay of Bengal
(NIO, Dona Paula, Goa (India), 2000)The role of the near-surface stratified layer developed due to the spread of low salinity waters under the influence of freshwater influx on the cyclogenesis over the Bay of Bengal is addressed. The seasonal variation of ... -
Directional spread parameter at intermediate water depth
(Pergamon, 2000)The characteristics of directional spread parameters at intermediate water depth are investigated based on a cosine power '2s' directional spreading model. This is based on wave measurements carried out using a Datawell ... -
Wave climatology of the Indian Ocean derived from altimetry and wave model
(NIO, Dona Paula, Goa (India), 2000)GEOSAT altimeter data for the period 1986-1989 have been utilised to derive wave climatology for the Indian Ocean region bounded by 20 degrees S to 25 degrees N and 40 degrees E to 110 degrees E. The results are presented ... -
Inertial currents in the Indian Ocean derived from satellite tracked surface drifters
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2000)Satellite-tracked surface drifters were used to analyze the characteristics of inertial currents in the tropical Indian Ocean. The drifters were drogued at 15 m depth and had wind-produced slips less than 0.1% of the wind ... -
Retrieval of sea surface velocities using sequential ocean colour monitor (OCM) data
(NIO, Dona Paula, Goa (India), 2000)The Indian Remote Sensing Satellite, IRS-P4 (Oceansat-I) launched on May 26, 1999 carried two sensors on board, i.e., Ocean Colour Monitor (OCM) and a Multifrequency Scanning Microwave Radiometer (MSMR) to study both ... -
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 ... -
Inter-annual variability of sea surface temperature, wind speed and sea surface height anomaly over the tropical Indian Ocean
(NIO, Dona Paula, Goa (India), 2000)Being land-locked at the north, the Indian Ocean and its surrounding atmosphere behave in such a way that the ocean-atmosphere interaction over this domain is different from that over the other oceans, exhibiting a peculiar ... -
Studies on thermal fields in the Bay of Bengal
(Indian Geological Congress, Roorkee, India, 2000)As an Indian component of the International Tropical Ocean Global Atmosphere (TOGA) program, the National Institute of Oceanography, Goa, has initiated a long-term observational program during 1990 with financial support ...
