Temporal and spatial variability of trace metals in suspended matter of the Mandovi estuary, central west coast of India
(Springer, 2012)Studies on the suspended particulate matter (SPM) in the Mandovi estuary, western India indicate that during the monsoon and pre-monsoon, the SPM increases, and the major and trace metals decrease from stations in the ... -
Drift in salinity data from Argo profiling floats in the Sea of Japan
(American Meteorological Society, 2012)In drift analysis of salinity sensors, one major problem is the difficulty in delineating sensor drift from water mass changes. In the present study, a new method is proposed for finding sensor drift that is free from water ... -
Comparison of measured and satellite-derived spectral diffuse attenuation coefficients for the Arabian Sea
(Taylor & Francis, 2012)The results of study comparing the spectral diffuse attenuation coefficients Kd(Lambda) measured in the Arabian Sea with those derived from the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) using three algorithms, of ... -
Denitrification prevails over anammox in tropical mangrove sediments (Goa, India)
(Elsevier, 2012)Denitrification, anammox (Anx) and di-nitrogen fixation were examined in two mangrove ecosystems- the anthropogenically influenced Divar and the relatively pristine Tuvem. Stratified sampling at 2 cm increments from 0 to ... -
Hydrothermal plumes over the Carlsberg Ridge, Indian Ocean
(American Geophysical Union, 2012)Water column surveys and sampling in 2007 and 2009 was conducted to search for hydrothermal plumes over a segment of the Carlsberg Ridge. An evidence for two separate vent fields, one near 3 degrees 42′N, 63 degrees 40′E ... -
A stratification prediction diagram from characteristics of geometry, tides and runoff for estuaries with a prominent channel
(Elsevier, 2012)Accepting the premise that it should be possible to predict stratification within an estuary from the characteristics of its geometry, tide at the mouth and runoff, we use data from 14 estuaries with a prominent channel ... -
A study of lead and cadmium speciation in some estuarine and coastal sediments
(Elsevier, 2012)Chemical speciation of lead (Pb) and cadmium (Cd) in the coastal and estuarine sediments along the central east coast of India was studied by applying sequential and kinetic extraction methods. The results of this study ... -
Empirical algorithm to estimate the average cosine of underwater light field at 490 nm
(Taylor & Francis, 2012)The average cosine of the underwater light field mu(lambda), where lambda is the wavelength, is an apparent optical property (AOP) that describes the angular distribution of radiance at a given point in water. Here, we ... -
Reducing Vibrio load in Artemia nauplii using antimicrobial photodynamic therapy: a promising strategy to reduce antibiotic application in shrimp larviculture
(Society for Applied Microbiology, 2012)Antimicrobial photodynamic therapy (aPDT) as an alternative strategy to reduce the use of antibiotics in shrimp larviculture systems is proposed. The growth of a multiple antibiotic resistant Vibrio harveyi strain was ... -
Characterisation of the bacteria associated with barnacle, Balanus amphitrite, shell and their role in gregarious settlement of cypris larvae
(Elsevier, 2012)The acorn barnacle Balanus amphitrite (syn. Amphibalanus amphitrite) is a model organism to investigate pelago-benthic transitions in marine invertebrates. A driver for larval settlement in this organism is the need to ... -
A multisensor climatological view of double ITCZs over the Indian Ocean
(Taylor & Francis, 2012)The climatological features of the double inter-tropical convergence zones (DITCZs) over the western Indian Ocean during November–December by a synergistic analysis of the Hamburg Ocean Atmosphere Parameters and Fluxes ... -
Characterization of seafloor pockmark seepage of hydrocarbons employing fractal: A case study from the western continental margin of India
(Elsevier, 2012)A quantitative technique is applied to describe the seafloor seepages based on the multi-beam backscatter and bathymetric investigations to characterize the pockmark morphology. The variable seafloor backscatter strength ... -
A new spectrofluorometric method for the determination of total arsenic in sediments and its application to kinetic speciation
(Taylor & Francis, 2012)A simple and sensitive spectrofluorometric method has been developed for the determination of arsenic (As) using rhodamine-B as a fluorescent agent. This method is based on the reaction of As(III) with potassium iodate ... -
Genetic algorithm based support vector machine regression in predicting wave transmission of horizontally interlaced multi-layer moored floating pipe breakwater
(Elsevier, 2012)Planning and design of coastal protection works like floating pipe breakwater require information about the performance characteristics of the structure in reducing the wave energy. Several researchers have carried out ... -
Geodynamics of the Amirante Ridge and Trench Complex, Western Indian Ocean
(Taylor & Francis, 2012)The formation and evolution of the approx. 600 km long arcuate Amirante Ridge and Trench Complex (ARTC) is a significant geomorphic– structural feature in the Western Indian Ocean (WIO). The WIO contains evidence of at ... -
Marine archaeological investigations along the Tamil Nadu coast and their implications for understanding cultural expansion to southeast Asian countrie
(Institute of Southeast Asian Studies, 2011)The marine archaeological exploration off Poompuhar and Mahabalipuram brought to light several underwater remains and the traditions mentioning the submergence of these towns have been partially confirmed. -
Hypoxia and Nutrient Reduction in the Coastal Zone: Advice for Prevention, Remediation and Research.
(Global Environment Facility, 2011)Coastal hypoxia is a complex problem and, although research has made great strides in understanding its causes and remedies, more knowledge is needed to fill critical gaps that impede action. -
Do cold, low salinity waters pass through the Indo-Sri Lanka Channel during winter?
(Taylor & Francis, 2011)During winter, along the east coast of India, the near-surface flow is characterized by the southward-flowing East India Coastal Current (EICC) which bends around Sri Lanka and enters into the south-eastern Arabian Sea ... -
Significance of biofilm proteins in modulating cyprid metamorphosis of Balanus amphitrite (Cirripedia: Thoracica)
(Blackwell Verlag GmbH, 2011)The role of biofilm proteins in modulating cyprid metamorphosis is not well understood. In the present investigation this possibility was explored by disrupting biofilm proteins using commercially available protease. The ... -
Occurrence of red tide caused by Karenia mikimotoi (toxic dinoflagellate) in the Southwest coast of India
(NISCAIR (CSIR), 2011)Intense brownish discoloration was observed in the surface waters of Cochin barmouth on 21st October 2009, which found to extend a few kilometers in the coastal waters. Continuous monitoring was carried out in the region ...
