Sonograph patterns of the central western continental shelf of India
(Tirunelveli: JCSONLINE, 1989)Side scan sonar and bathymetric surveys were conducted on the central western continental shelf of India. The sonographs portray a smooth, relatively featureless inner shelf, up to a depth less than 40-50 m, which is covered ... -
Sound field computations in the Bay of Bengal using parabolic equation method
(NISCAIR, CSIR, 1996)Effect of the cold core eddy in the Bay of Bengal on acoustic propagation was analysed by parabolic equation (PE) method. Source depth, frequency and propagation range considered respectively for the two numerical experiments ... -
Sound speed structure in the Arabian Sea and the Bay of Bengal
(NISCAIR, New Delhi, 1993)Sound speed computed from annual mean temperature and salinity data of Levitus reveals that spatial variation in the Arabian Sea is greater than that in the Bay of Bengal. Maximum spatial variation of sound speed in the ... -
Sound speed variation in the coastal waters off Cochin and signature of subsurface maxima
(Springer, 2021)We investigated the vertical and horizontal variation of the sound speed using the Thermodynamic Equation Of Seawater-2010 (TEOS-10) and monthly CTD observations at Cochin estuary and adjacent coastal waters (inlet to 20 ... -
Sound-speed prediction as a function of temperature at discrete depths in the Bay of Bengal

Sound-speed structure and propagational characteristics of a cold core eddy in the Bay of Bengal
(Indian Society for Physical Sciences of the Oceans, 1992)An analysis of acoustic characteristics of a cold core eddy in the Bay of Bengal reveals that the eddy introduces in sound-speEd. by about 10 ms-1. The depth of deep sound channel axis beneath eddy remains constant whereas ... -
Source analysis of radiocesium in river waters using road dust tracers
(Pergamon, 2017)Following the Fukushima Dai-ichi Nuclear Power Station accident, regional road dust, heavily contaminated with radiocesium, now represents a potential source of radiocesium pollution in river water. To promote effective ... -
Source and dispersal of suspended sediment in the macro-tidal Gulf of Kachchh
(Elsevier, 2007)The macro-tidal Gulf of Kachchh, covering nearly 7000 km sup(2), is located about 150 km south of the Indus River mouth. In spite of semi-arid climate and lack of major rivers flowing into it, the Gulf is highly turbid ... -
Source characterisation of Sedimentary organic matter in mangrove ecosystems of northern Kerala, India: Inferences from bulk characterisation and hydrocarbon biomarkers
(Elsevier, 2016)Surface sediment samples from five mangrove ecosystems along the Kerala coast, north of Kochi were analysed for elemental ratios, stable isotopes of carbon and hydrocarbon biomarkers (n-alkanes, n-alkenes and hopanes) to ... -
Source identification of a tar residue from Mumbai Beach
(NISCAIR, CSIR, 1996)A tar residue from Mumbai Beach, Maharashtra, India was matched with the suspected source sample from a tanker using UV, IR and GLC techniques. Negligible differences in several ratios of UV absorbances and ratios of ... -
Source investigation of the tar balls deposited along the Gujarat coast, India, using chemical fingerprinting and transport modeling techniques
(American Chemical Society, 2014)Deposition of tar balls (TBs) along the south Gujarat coast, situated on the west coast of India (WCI), commonly occurs during the southwest monsoon season. Several offshore oil fields off the Mumbai-Gujarat coast, and ... -
Source rock indication from the heavy mineral weight percentages, central Tamil Nadu, India
(Macmillan, India, 2007)From December 2003 to December 2005 beach sand samples have been collected at regular intervals. During this period the event of 26th December, 2004 tsunami enabled us to analyze the impact of the same in the beach sediments ... -
Sources and distribution of organic matter in thirty five tropical estuaries along the west coast of India-a preliminary assessment
(Elsevier, 2014)Studies characterizing the sources of organic matter (OM) to the west coast of India (WCI) and its continental shelf are limited. This study examined sedimentary OM in 35 estuaries along the WCI using molecular biomarkers ... -
Sources and fate of organic matter in suspended and bottom sediments of the Mandovi and Zuari estuaries, Western India
(Current Science Association, 2015)Organic carbon (OC), total nitrogen (TN) and stable carbon and nitrogen isotopic compositions were measured in suspended particulate matter (SPM) and surface sediment along estuaries of Mandovi and Zuari rivers, two small ... -
Sources and implications of particulate organic matter from a small tropical river-Zuari River, India
(Springer Verlag, 2020)Transitional ecosystems, estuaries and the coastal seas, are distinctively affected by natural and anthropogenic factors. Organic matter (OM) originating from terrestrial sources is exported by rivers and forms a key ... -
Sources and preservation dynamics of organic matter in surface sediments of Narmada River, India - Illustrated by amino acids
(2020)The preservation process of organic matter (OM) in estuarine environments determines the recycling and sinking of nutrients. This process requires the identification of sources, degradation states and the main processes ... -
Sources and sinks of CO2 in the west coast of Bay of Bengal
(International Meteorological Institute in Stockholm, 2012)Observations at high spatial resolution (100 x 50 km sup(2)) in the western continental shelf of Bay of Bengal during southwest monsoon, when peak discharge occurs into the Bay through major rivers of the Indian subcontinent, ... -
Sources of errors in the measurements of underwater profiling radiometer
(CSIR-NISCAIR, 2014)There are various sources of errors from the measurements of optical parameters using a radiometer, which can be classified as mode of deployment, instrument and environment. The errors from the deployment are primarily ... -
