Early (pre–8 Ma) fault activity and temporal strain accumulation in the central Indian Ocean
(The Geological Society of America, 2009)The diffuse deformation zone in the central Indian Ocean is the classical example of distributed deformation of the oceanic lithosphere, where shortening between the Indian and Capricorn plates is manifest as reverse ... -
Spectral characteristics of the nearshore waves off Paradip, India during monsoon and extreme events
(Springer, 2009)Spectral and statistical wave parameters obtained from the measured time series wave data off Paradip, east coast of India during May 1996-January 1997 were analysed along with MIKE 21 spectral wave model (SW) results. ... -
Demarcation of inland vessels' limit off Mormugao port region, India: A pilot study for the safety of inland vessels using wave modelling
(Springer, 2009)The Ministry of Shipping desires to revise the inland vessels' limit (IVL) notification based on scientific rationale to improve the safety of vessels and onboard personnel. The Mormugao port region extending up to the ... -
Phenanthrene and nitrite effects on juvenile sea bass, Dicentrarchus labrax, using hepatic biotransformation enzymes, biliary fluorescence, and micronuclei as biomarkers
(Universidad Autónoma de Baja California, 2009)Aquatic organisms may absorb organic compounds mainly from water and by ingestion of contaminated food. The toxicity of such compounds may be intensified by the presence of certain inorganic compounds such as nitrite (NO ... -
A special core liner for sub-sampling of aqueous sediments
(Current Science Association, 2009)A portable and reusable special core liner (spcl) has been developed to accomplish real-time sub-sampling of aqueous sediments. Besides being revolutionary, inexpensive and user-friendly, the spcl is capable of collecting ... -
Diffuse reflectance infrared fourier transform spectroscopic (DRIFTS) investigation of E.coli, Staphylococcus aureus and Candida albicans
(NISCAIR, India, 2009)The present study consists of a refined method for obtaining Diffuse Reflectance Infrared Fourier Transform Spectroscopic (DRIFTS) data for biological samples in the mid infrared region (4000 - 600 cm sup(-1)). The biological ... -
Evolution of the Late Cretaceous crust in the equatorial region of the Northern Indian Ocean and its implication in understanding the plate kinematics
(The Royal Astronomical Society, 2009)Analysis of 3100 km of newly acquired marine magnetic data, constrained by satellite and shipborne free air gravity anomalies, in the corridor between the 86°E fracture zone (FZ) and Ninetyeast Ridge, north of the equator ... -
Observed tides at Mumbai High offshore region near the continental shelf break in the eastern Arabian Sea
(Current Science Association, 2009)The observed large tidal range (up to 3 m during spring tide) at the Mumbai High offshore region located near the continental shelf break, off the central west coast of India, is described based on simultaneous tidal ... -
Physico-chemical characteristics of the coastal water off Devi estuary, Orissa and evaluation of its seasonal changes using chemometric techniques
(Current Science Association, 2009)Devi estuary is one of the major tributaries of the Mahanadi riverine system in Orissa. Modernization and industrialization in its neighbourhood in the north in the recent past have greatly influenced many tributaries of ... -
Mercury enrichment in sediments of Amba estuary
(NISCAIR, India, 2009)Concentrations of Hg, total organic carbon (TOC), Al, Fe and Mn were determined in sediment of the Amba Estuary between the mouth and the head over a distance of 24 km in December and May during 1997-2002. Temporal and ... -
Potential diagenetic and detrital sources for calcareous sediments from the Carlsberg Ridge, Indian Ocean
(Current Science Association, 2009)Six sediment cores from the Carlsberg Ridge (CR) were studied for elemental concentration, magnetic susceptibility (chi), grain size and clay mineral distribution, and sedimentation rate to decipher possible detrital and ... -
