Seasonal variations of total suspended matter (TSM) in the Gulf of Khambhat, west coast of India
(CSIR-NISCAIR, 2014)Total Suspended Matter (TSM)is an important parameter for determining the water quality in coastal regions as it is responsible for the reduction in the light available to the aquatic vegetation which subsequently alters ... -

Land use/land cover changes around Rameshwaram Island, east coast of India
(CSIR-NISCAIR, 2014)Land-use/land cover changes are studied using the Indian Remote Sensing satellite (IRS-1C, IRS-6) Linear Image Self-scan Sensor (LISS) III data of 1998 and 2010 Coastal land use categories such as sand, vegetation, coral ... -
ENSO-induced inter-annual sea level variability in the Singapore strait
(CSIR-NISCAIR, 2014)Sea level data from four tide gauge stations in the SS (Tanjong Pagar, Sultan Shoal, Sembawang and Raffles Lighthouse) for the period 1970-2012 were extracted to study the ENSO-induced interannual sea level variability Sea ... -
Spectral analysis of wind field in the Indian Ocean
(CSIR-NISCAIR, 2014)To study the variability in wind fields over the Indian Ocean, we used ERA INTERIM daily winds for the period 1979-2012 In order to analyse the temporal variation of wind field, we partitioned the whole Indian Ocean into ... -
Morpho-dynamic evolution of Ekakula spit of Odisha coast, India using satellite data
(CSIR-NISCAIR, 2014)Ekakula spit is t at the northern end of Gahirmatha coast in the state of Odisha, India This spit is located at the mouth of Maipura River which is falling in the Mahanadi delta region This spit is a prominent and important ... -
Coastal changes along the coast of Tadri River, Karnataka West coast of India and its implication
(CSIR-NISCAIR, 2014)Present study of the coastal changes in Tadri, Uttara Kannada district of Karnataka, comparing Survey of India Toposheet, Coastal Zone Management Plan of Karnataka and traditional ground survey measurement merged with multi ... -
Modelling of wave propagation over a submerged sand bar using SWASH
(CSIR-NISCAIR, 2014)A non-hydrostatic numerical model "SWASH" (Simulating WAves till SHore) is used to study the wave propagation over a submerged sand bar in a wave flume The SWASH model is calibrated and further used to validate the wave ... -
Active and break events of Indian summer monsoon during 1901-2014
(Springer, 2016)The study lists active and break monsoon events over India over a very long period (1901-2014) identified using criteria based on a rainfall index derived over a critical high rainfall region called core monsoon zone. The ... -
Impact of port structures on the shoreline of Karnataka, west coast, India
(Cloud Publications, 2016)The changes in shoreline positions and geomorphic features along the Karnataka, West coast of India, were studied for the period from 1973 to 2014, using multi-dated satellite images and topographic maps. The ten hotspots ... -
Baseline geophysical data for hazard management in coastal areas in relation to earthquakes and tsunamis
(Sage Publication, 2016)A systematic study of geophysical data of the Eastern Continental Margin of India was taken up to identify the land-ocean tectonic lineaments over the east coast of India and the possible neotectonic activity associated ... -
Role of distinct flavours of IOD events on Indian summer monsoon
(Springer, 2016)The summer monsoon contributes to about 75 % of mean annual rainfall over the various meteorological subdivisions of India. The role of ocean–atmosphere phenomena such as Indian Ocean Dipole (IOD) and El Nino-Southern ... -
Basement configuration of KG offshore basin from magnetic anomalies
(Indian Academy of Sciences, 2016)Marine magnetic anomalies along three representative profiles falling between shelf break and continent-ocean boundary in the offshore Krishna-Godavari basin were quantitatively interpreted for understanding the nature and ... -
Cyclone and monsoonal wave characteristics of northwestern Bay of Bengal: long-term observations and modeling
(Springer, 2016)Long-term wave data play a crucial role in arriving the wave criteria for ports and harbors and shore protection structures. Seasonal and annual wave characteristics are studied based on wave data collected for the year ... -
Response of sheltered and built-up coasts in the wake of natural hazards: The aftermath of the December 2004 Tsunami, Tamil Nadu, India
(Springer, 2016)The geomorphology and the disposition of natural features and type of coast are major factors that control wave heights and govern consequent inundation distances. The connection between tsunami run-up heights and inundation ... -
Assessing the suitability of benthic foraminiferal morpho-groups to reconstruct paleomonsoon from Bay of Bengal
(Indian Academy of Sciences, 2016)Temporal changes in benthic foraminiferal morpho-groups were suggested as an effective proxy to reconstruct past monsoon intensity from the Arabian Sea. Here, in order to test the applicability of temporal variation in ... -
Diversity and activity of methanotrophic related bacteria in subsurface sediments of the Krishna-Godavari Basin, India
(Current Science Association, 2016)The present study assesses the distribution, diversity and activity of aerobic methanotrophic related bacteria (MRB) dwelling in Krishna-Godavari (KG) basin, India. The counts of MRB ranged from non-detectable(ND) to 8.6 ... -
