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
(CSIR-NISCAIR, 1972) -
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 ... -
Variability in the phytoplankton community of Kavaratti reef ecosystem (northern Indian Ocean) during peak and waning periods of El Ni�o 2016
(Springer, 2017)El Ni�o, an interannual climate event characterized by elevated oceanic temperature, is a prime threat for coral reef ecosystems worldwide, owing to their thermal threshold sensitivity. Phytoplankton plays a crucial role ... -
Variability in tidal harmonics of the coastal and estuarine waters of Goa during winter monsoon and spring inter-monsoon
(Elsevier, 2022)Harmonic analysis was carried out with simultaneously observed tide elevation in the coastal and estuarine regions of Goa. The tide elevations were consistent along the coastal stretch of 80 km; however, significant ... -
Variability in wave refraction and resultant nearshore current patterns: Exposed versus sheltered beaches along north Karnataka, west coast of India
(CSIR-NISCAIR, 1988)For predominant waves approaching from directions varying between SW and WNW and periods varying from 6 to 11 sec, the refraction function (Kd) shows amplification of wave heights resulting in concentration of wave energy ... -
Variability of biochemical compounds in surface sediments along the eastern margin of the Arabian Sea
(Springer, 2023)Different fractions of organic matter in surface sediments from three transects along the eastern margin of the Arabian Sea (AS) were quantified to determine the sources of organic matter, and also to study its impact on ... -
Variability of dissolved oxygen in the Arabian Sea Oxygen Minimum Zone and its driving mechanisms
(2020)The Arabian Sea hosts one of the most intense, perennial Oxygen Minimum Zones (OMZ) in the world ocean. Observations along a meridional transect at 68°E extending from 8 to 21°N showed large seasonal as well as interannual ... -
Variability of frontal structure in the south Indian/Antarctic Ocean: Possible reason for longitudinal differences in the intensity of the oxygen maximum
(Goa: National Inst of Oceanography, 1987) -
Variability of hydromedusae from Aroor, Cochin backwaters
(Goa: National Inst of Oceanography, 1977) -
Variability of intraseasonal oscillations and synoptic signals in sea surface salinity in the Bay of Bengal
(2019)Intraseasonal oscillations (ISOs) significantly impact southwest monsoon precipitation and Bay of Bengal (BoB) variability. The response of ISOs in sea surface salinity (SSS) to those in the atmosphere is investigated in ... -
Variability of mixed layer depth in the northern Indian Ocean during 1977 and 1979 summer monsoon seasons
(CSIR-NISCAIR, 1988)Influences of wind stress (tau) and wind stress curl (Grad Gamma) on the short term variability of the mixed layer depth at different locations in the northern Indian Ocean during different phases of summer monsoon activity ... -
Variability of Mn, Fe, Ni, Cu and Co in manganese nodules from the Central Indian Ocean Basin
(Elsevier, 1989)The trace element variations in manganese nodules from the Central Indian Basin have been related to the underlying sediment type. Percentages of Mn, Cu and Ni are high in nodules occurring in siliceous sediments compared ... -
Variability of nitrate and phosphate
(National Institute of Oceanography, India, 2007)Nitrate and phosphate are important elements of the biogeochemical system of an estuary. Observations carried out during the dry season April-May 2002, and March 2003 and wet season September 2002, show temporal and spatial ... -
Variability of organic nitrogen and its role in regulating phytoplankton in the eastern Arabian Sea
(Elsevier, 2019)The relative importance of organic nitrogen (ON) and inorganic nitrogen (IN) as nitrogen sources for the phytoplankton communities were studied through a seasonal time series of nitrogen species in the eastern Arabian Sea. ... -
