16S rRNA-based bacterial diversity in the organic-rich sediments underlying oxygen-deficient waters of the eastern Arabian Sea
(Springer, 2011)The eastern Arabian Sea has a unique and permanent oxygen minimum zone (OMZ) that extends along the western continental margin of India. The sediment below this region is rich in organic matter. This study describes the ... -
Sea surface salinity variability during the Indian Ocean Dipole and ENSO events in the tropical Indian Ocean
(American Geophysical Union, 2011)An ocean reanalysis that covers the period from 1871 to 2008 is used to analyze the interannual variability of sea surface salinity (SSS) in the tropical Indian Ocean. The reanalysis SSS and the SSS anomaly patterns during ... -
Marine archaeological investigations on Tamil Nadu Coast, India: A overview
(Asian Academy of Heritage Management, 2011)Ancient ports such as Kaveripattinam, Nagapattinam, Korkai, Alagankulam, Periyapattinam, all on Tamil Nadu coast have played a dominant role in the transoceanic trade and commerce with many countries since the beginning ... -
Maritime archaeology of Gujarat: Northwest coast of India
(Asian Academy of Heritage Management, 2011)Asia-Pacific Regional Conference on Underwater Cultural Heritage Proceedings. Eds. by: Staniforth, M.; Craig, J.; Jago-on, S.C.; Orillaneda, B.; Lacsina, L.(Asia-Pacific Regional Conference on Underwater Cultural Heritage; ... -
Does sea level pressure modulate the dynamic and thermodynamic forcing in the tropical Indian Ocean?
(Taylor & Francis, 2012)Three areas, the north Indian Ocean (NIO), the equatorial Indian Ocean (EIO) and the south Indian Ocean (SIO), were chosen over the tropical Indian Ocean to investigate the dependency of sea surface temperature (SST), wind ... -
Does carbonate ion control planktonic foraminifera shell calcification in upwelling regions?
(Current Science Association, 2011)Planktonic foraminifera shell weights have been recognized as possible proxy for surface water carbonate ion concentration [CO sup(=) sub(3)] and atmospheric CO sub(2). However, to utilize this proxy, it is important to ... -
Intra-annual variability of carbon and nitrogen stable isotopes in suspended organic matter in waters of the western continental shelf of India
(The European Geosciences Union, 2011)Intra-annual variations of delta sup(13)C and delta sup(15)N of watercolumn suspended particulate organic matter (SPOM) have been investigated to understand the biogeochemical cycling of C and N in the Western Continental ... -
Vibrio plantisponsor sp. nov., a diazotrophic bacterium isolated from a mangrove associated wild rice (Porteresia coarctata Tateoka)
(Elsevier, 2011)Two Gram negative, facultatively anaerobic, halophilic, motile, slightly curved rod-shaped bacterial strains MSSRF60 sup(T) and MSSRF64 were isolated from the roots of a mangrove-associated wild rice collected in the ... -
Instrumentation for high-frequency meteorological observations from research vessel
(Marine Technology Society, 2011)Ship provides an attractive platform from which high-frequency meteorological observations (e.g., wind components, water vapor density, and air temperature) can be made accurately. However, accurate observations of ... -
Contribution of mesoscale processes to nutrient budgets in the Arabian Sea
(American Geophysical Union, 2011)We examine the impact of mesoscale dynamics on the seasonal cycle of primary production in the Arabian Sea with an eddy-resolving (1/12 degrees) bio-physical model. Comparison with observations indicates that the numerical ... -
Baseline of organotin pollution in fishes, clams, shrimps, squids and crabs collected from the west coast of India
(Elsevier, 2011)Organotins, especially tributyltins (TBT) are highly toxic to many marine organisms. These compounds are introduced in marine waters by ship trafficking, ship scrapping activities, as antifouling compounds and sewage ... -
Processes controlling the surface temperature signature of the Madden–Julian Oscillation in the thermocline ridge of the Indian Ocean
(Springer, 2011)During boreal winter, there is a prominent maximum of intraseasonal sea-surface temperature (SST) variability associated with the Madden–Julian Oscillation (MJO) along a Thermocline Ridge located in the southwestern Indian ... -
Phylogenetic diversity of carbohydrate degrading culturable bacteria from Mandovi and Zuari estuaries, Goa, west coast of India
(Elsevier, 2011)Coastal and estuarine waters are highly productive and dynamic ecosystems. The complex carbohydrate composition of the ecosystem would lead to colonisation of microbial communities with abilities to produce an array of ... -
Occurrence of faecal pellet-filled simple and composite burrows in cold seep carbonates: A glimpse of a complex benthic ecosystem
(Elsevier, 2011)Ichnofossils preserved in marine sedimentary records provide unique information on various activities (feeding, dwelling, excretion etc.) of benthic organisms. Here we report faecal pellet-filled tubular (simple and ... -
Impact of oxygen-depleted water on the vertical distribution of chaetognaths in the northeastern Arabian Sea
(Elsevier, 2011)The influence of a thick layer of oxygen-depleted water (<0.2 ml l sup(-1)) on the abundance and distribution of chaetognaths was investigated in the northeastern Arabian Sea (NEAS), a natural oxygen-deficient system in ... -
An overview of shipwreck explorations in Goa waters
(Asian Academy of Heritage Management, 2011)Since the beginning of maritime archaeological research in Indian waters, marine records housed in archives of India and abroad provide details of the shipwrecks and the loss of Indian ships in foreign waters. Information ... -
Spectral variations of UV-A and PAR solar radiation in estuarine waters of Goa
(IEEE, 2011)The spectral solar radiation measurements in the range 350-800 nm were carried out in the estuarine waters of Goa using hyperspectral radiometer. The results of the analysis of solar light in the spectral range of ... -
Benthic polychaetes in the Ratnagiri bay, India: Influence of anthropogenic factors
