REE in suspended particulate matter and sediment of the Zuari estuary and adjacent shelf, western India: Influence of mining and estuarine turbidity
(Elsevier, 2013)Concentrations of Al, Fe, Mn and rare earth elements (REE) were measured in 122 samples of suspended particulate matter (SPM) and 70 surficial sediments from the Zuari estuary and the adjacent shelf to understand their ... -
Variation in the Indian summer monsoon intensity during the Bolling-Allerod and Holocene
(American Geophysical Union, 2013)Variations in the Indian summer monsoon (ISM) intensity during the last 16.7 ka have been studied using organic carbon (C<sub>org</sub>), delta <sup>15</sup>N of sedimentary organic matter, CaCO<sub>3</sub>, sediment ... -
Directionality and spread of shallow water waves along the eastern Arabian Sea
(Copernicus Publications, 2013)The directional characteristics of shallow water waves are described based on measured data during 2011 at two locations spaced at 350 km along the eastern Arabian Sea. Study shows that, for high swells (significant wave ... -
Oxidative stress and antioxidant indices of marine alga Porphyra vietnamensis
(University of Zagreb, 2013)Oxidative stress and antioxidant defence systems were assessed in a marine red alga Porphyra vietnamensis Tanaka et Pham-Hoang Ho, from India. Lipid peroxidation (LPX) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) ... -
Indian Ocean Dipole and El Nino/Southern Oscillation impacts on regional chlorophyll anomalies in the Indian Ocean
(Copernicus Publications, 2013)The Indian Ocean Dipole (IOD) and the El Niño/Southern Oscillation (ENSO) are independent climate modes, which frequently co-occur, driving significant interannual changes within the Indian Ocean. We use a four-decade ... -
Effect of eyestalk extirpation on haemolymph ionic concentration of Metapenaeus monoceros
(Horizon Publisher, 2013)Metapenaeus monoceros in the size range 65-70mm was subjected to the evaluation of sodium(Na<sup>+</sup>),, potassium (K<sup>+</sup>) and calcium (Ca<sup>2+</sup>) ionic concentration in the haemolymph after unilateral ... -
Biometric and morphometric studies of Perna viridis and Perna indica along the southwest coast of India: a statistical approach
(Horizon Publisher, 2013)The growth indices of the Mussels, Perna viridis and Perna indica collected from the south west coast of India were examined using statistical methods. The Principal Component Analysis (PCA) and Exploratory Factor Analysis ... -
Observed tidal currents on the continental shelf off the west coast of India
(Elsevier, 2013)Observed currents from ADCPs, deployed at 100 m and 150 m depths, on the continental shelf at five different locations along the west coast of India, were used to study the characteristics of both barotropic and baroclinic ... -
Particle backscattering variability in the coastal waters of Bay of Bengal: A case study along off Kakinada and Yanam Regions
(IEEE, 2013)The distribution and variability of particulate back scattering coefficient (b<sub>bp</sub>) in the Godavari basin are reported for the first time using in situ measurements. A coastal cruise was conducted in the coastal ... -
Coastal erosion triggered by a shipwreck along the coast of Goa, India
(Current Science Association, 2013)Temporal satellite imageries (1999, 2001, 2003, 2006, 2008 and 2011), wave model (DHI) results and field measurements have been used to evaluate whether the grounded ship MV River Princess played a role in triggering erosion ... -
Coastal sensitivity mapping of Gulf of Kachchh and Gulf of Cambay, India
(Hasanuddin University, Indonesia, 2013)In this study, two major Gulf regions (Gulf of Kachchh, Gulf of Cambay) along the west coast of India have been selected for their coastal sensitivity. These two gulfs region have the highest number of ports in the country ... -
Complexities in coastal sediment transport studies by numerical modelling
(Hasanuddin University, Indonesia, 2013)Marine environmental studies related to erosion, accretion, pollution transport, dredge disposal, location of seawater intake, effluent disposal, etc., involve sediment transport studies. Numerical models use set of well ... -
