Backtrack modeling to locate the origin of tar balls depositing along the west coast of India
(Elsevier, 2016)Tar ball (TB) deposition along the West Coast of India (WCI) is a common phenomenon during the southwest monsoon season, particularly along the coast of Goa and Gujarat, and it is a major concern to the stake holders. Our ... -
Preliminary results of algorithms to determine horizontal and vertical underwater visibilities of coastal waters
(SPIE, 2016)Algorithms developed for underwater horizontal and vertical visibilities are presented. The algorithms have been developed to derive the underwater visibilities based on the contrast theory using the in-situ and Hydrolight ... -
Preliminary results of an algorithm to determine the total absorption coefficient of water
(Society of Photo-Optical Instrumentation Engineers, 2016)An algorithm to determine the spectral total absorption coefficient of water is presented. The algorithm is based on the Gershun’s equation of alfa = micro K<sub>E</sub>. The spectral underwater average cosine, micro and ... -

(CSIR-NISCAIR, 2015)In present study, the prevalence of enteric bacterial indicators like Escherichia coli, Salmonella, Shigella, Proteus, Klebsiella, Vibrio cholerae and Vibrio parahaemolyticus like organism in water and sediment of Veraval ... -
Tropical cyclones over NIO during La-Nina Modoki years
(CSIR-NISCAIR, 2015)Tropical cyclones over NIO (North Indian Ocean) are highly influenced by the El-Nino and La-Nina activities over the Pacific Ocean Influences of air-sea interaction processes like El-Nino Modoki and La-Nina Modoki on ... -
Lithospheric stretching and the long wavelength free-air gravity anomaly of the Eastern Continental margin of India and the 85 degree E Ridge, Bay of Bengal
(CSIR-NISCAIR, 2015)Among the submarine ridge systems in the northern Indian Ocean, the 85 degree E Ridge in the Bay of Bengal is more enigmatic owing to its peculiar anomalous negative free-air gravity. In general, this has been attributed ... -
On some aspects of Indian Ocean warm pool
(CSIR-NISCAIR, 2015)Annual and interannual variation of Indian Ocean Warm Pool (IOWP) was studied using satellite and in situ ocean temperature data IOWP surface area undergoes a strong annual cycle attaining a maximum of 24x10<sup>6</sup>k ... -
Lithosphere structure and upper mantle characteristics below the Bay of Bengal
(The Royal Astronomical Society, 2016)The oceanic lithosphere in the Bay of Bengal (BOB) formed 80-120 Ma following the breakup of eastern Gondwanaland. Since its formation, it has been affected by the emplacement of two long N-S trending linear aseismic ridges ... -
Epibiotic community on the acorn barnacle (Balanus amphitrite) from a monsoon-influenced tropical estuary
(Blackwell Verlag GmbH, 2016)The epibiotic communities (diatoms and metazoans) on the outer surfaces of the shell of the barnacle Balanus amphitrite (BSh) and its opercular valves (the scutum and tergum; BST) were investigated on a monthly basis for ... -
Teak (Tectona grandis L.f.): A preferred timber for shipbuilding in India as evidenced from shipwrecks
(Current Science Association, 2016)One of the greatest achievements of man is the design and development of a variety of watercraft suitable for marine and riverine purposes and safer for the environment. From ancient times, timber was the main component ... -
Antioxidative metabolites synthesized by marine pigmented vibrio sp. and its protection on oxidative deterioration of membrane lipids
(Springer, 2016)Bacterial strain Vibrio sp. (PIGB 184) isolated from water samples of the Arabian Sea and identified through 16S rRNA demonstrated the production of pigmentary antioxidants with higher ABTS activities 90.9±0.42 % in ... -
Spectral wave climatology off Ratnagiri, northeast Arabian Sea
(Springer, 2016)Wave spectra of the measured data at 13 m water depth off Ratnagiri using the Datawell Directional waverider buoy from March 2010 to November 2014 are used to study the daily, monthly, seasonal and annual variations in the ... -
Phosphorous fractionation in mangrove sediments of Kerala, south west coast of India: the relative importance of inorganic and organic phosphorous fractions
(Springer, 2016)The study of phosphorous dynamics in mangrove ecosystems of the northern Kerala coast aims to delineate its relationships with other biogeochemical parameters. Our intension is to check the validity of the hypothesis that ... -
Crustal accretion at a sedimented spreading center in the Andaman Sea
(Geological Society of America, 2016)The magmatic, tectonic, and hydrothermal processes forming the oceanic crust along mid-ocean spreading centers are strongly modified at sedimented spreading centers but poorly understood owing to the lack of good crustal ... -
Directional characteristics of shallow water waves along southwestern Bay of Bengal
(Elsevier, 2016)The aim of the present research is to investigate the directional characteristics of waves along the southwestern Bay of Bengal based on the measured data during 2010 at 14 m water depth. Diurnal, monthly and annual variation ... -
