Validation of argo data in the Indian Ocean
(Universidad de Concepcion, 2004)ARGO-salinity data from the Indian Ocean are validated using salinity from float-versus-float match-ups and also using CTD observations from three cruises. Validation data sets are selected in such a way that the float and ... -
Validation of EIA sampling methods - bacterial and biochemical analysis
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)Deep sea sediments from Central Indian Ocean Basin (CIOB) were sampled from 10 degrees .00'-10 degrees .10'S latitude and 75 degrees .55'-76 degrees .05'E longitude for assessing the potential environmental impact of ... -
Validation of ERS-1 and high-resolution satellite gravity with in-situ shipborne gravity over the Indian offshore regions: Accuracies and implications to subsurface modeling
(Taylor & Francis, 2007)Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geoscientific investigations. Keeping this in mind, we have validated ERS-1 (168 day repeat) altimeter data and very ... -
Validation of multi-channel scanning microwave radiometer on-board Oceansat-1
(Indian Academy of Sciences, 2004)Sea surface temperature (SST), sea surface wind speed (WS) and columnar water vapour (WV) derived from Multi-frequency Scanning Microwave Radiometer (MSMR) sensor on-board IRS-P4 (Oceansat-1) were validated against the in ... -
Validation of multi-channel scanning microwave radiometer onboard OCEANSAT - 1
(Allied, India, 2003)IRS-P4 (OCEASAT-1) was the first operational oceanographic satellite that India has launched. An extensive validation campaign was unleashed immediately after its launch in May 1999. Various platforms (Ship, Moored buoy, ... -
Validation of salinity data from ARGO floats: Comparison between the older ARGO floats and that of later deployments
(The Korean Earth Science Society, 2005)Continued observation of ARGO floats or years (about 4 years) makes the conductivity sensor more vulnerable to fouling by marine life and associated drift in salinity measurements. In this paper, we address this issue by ... -
Validation of satellite derived LHF using coare_3.0 scheme and time series data over north-east Indian Ocean
(Universidad de Concepcion, 2004)Time series measurement of surface meteorological parameters using an Autonomous Weather Station and Moored Buoy positioned at 10.5 N and 72 E from July to November 2000 are used to compute latent heat flux (LHF) using ... -
Validation of satellite-derived tropical cyclone heat potential with in situ observations in the North Indian Ocean
(Taylor & Francis, 2012)Tropical cyclone heat potential (TCHP) is an important ocean parameter influencing cyclones and hurricanes. The best approach for computing TCHP is to use in situ measurements. However, since in situ data have both spatial ... -
Validation of sea surface temperature, wind speed and integrated water vapour from MSMR measurements. Project report
(National Institute of Oceanography, India, 2003)IRS-P4 (OCEANSAT-1) is the first operational oceanographic satellite that India has launched. An extensive validation campaign was unleashed immediately after its launch in May 1999. Various platforms (viz., ship, moored ... -
Validity of zooplankton biomass estimates and energy equivalent in the Indian Ocean
(CSIR-NISCAIR, 1986)Analysis of the published data on zooplankton biomass in the Indian Ocean reveals that due to omission of data from highly productive neritic Waters, the projected values of 519 x 10 6 tons become underestimated by 91 x ... -
Variability in abundance and fluxes of dimethyl sulphide in the Indian Ocean
(Springer, 2007)Dimethyl sulphide (DMS) is a biogenic gas of climatic significance on which limited information is available from the Indian Ocean. To fill in this gap, we collected data on DMS and DMSPt (total dimethylsulphoniopropionate) ... -
Variability in biological responses influenced by upwelling events in the Eastern Arabian Sea
(Elsevier, 2008)This study documents the result of field observations from the southeastern Arabian Sea during onset, peak and late phases of summer monsoon. The pronounced variations in phytoplankton standing stock (chlorophyll a), primary ... -
Variability in concentrations and fluxes of methane in the Indian estuaries
(Coastal and Estuarine Research Federation, 2016)In order to examine the fluxes of methane (CH4) from the Indian estuaries, measurements were carried out by collecting samples from 26 estuaries along the Indian coast during high discharge (wet) and low water discharge ... -
Variability in distribution of chaetognaths in the Arabian Sea

Variability in measured current structure on the southwest continental shelf of India
(The Coastal Education and Research Foundation, 2007)Analyses of short duration current meter records collected in the coastal waters off Beypore on the southwest coast of India have been made to understand the tidal and non-tidal variability during premonsoon and summer ... -
Variability in phytoplankton shape dominance in marine pelagic systems: prevalence of different adaptive strategies in the eastern Arabian Sea during the winter monsoon
(Springer, 2023)Phytoplankton communities from pelagic systems were assessed to explore the potential of using commonly used traits (such as cell geometry and taxa) as ecological function indicators from the data generated during the ... -
Variability in Protein Expression in Marine-Derived Purpureocillium lilacinum Subjected to Salt and Chromium Stresses
(Springer India, 2018)Abiotic factors can cause substantial limitation of growth of microbes. A combination of salinity stress along with chromium (Cr+6), one of the carcinogen, can pose an immediate threat to any living system. To understand ... -
Variability in stratification and flushing times of the Gautami-Godavari estuary, India
(Indian Academy of Sciences, 2015)In order to examine the influence of forcing (river flow and tides) and anthropogenic activities (dredging and dam regulation) on stratification, a study was conducted over a period of 19 months (June 2008– December 2009) ... -
Variability in the distribution of planktonic fish eggs and larvae in the nearshore waters off Bombay
(Indian Fisheries Association, 1978)Distribution of planktonic fish eggs and larvae in the nearshore waters off Bombay was studied during November 1979 to December 1980. Monthly samples were collected along three transects (Versova, Mahim and Thana) covering ... -
