210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
(Wiley, 2008)Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ... -
Role of Effective Density in improving the accuracy of bottom pressure based sea level measurements - A case study from Gulf of Guinea
(Singapore: IEEE Singapore Section Secretariat, 2006)Seasonal observations of a set of bottom pressures and concurrent tide-staff measurements from Takoradi harbour located in the Gulf of Guinea indicated that the effective depth-mean density value, rho sub(eff) of this clear ... -

Evaluation of antioxidant and antimicrobial activity of seaweed ( Sargassum sp.) extract: A study on inhibition of glutathione-S-transferase Activity
(The Scientific and Technological Research Council of Turkey, 2008)In the present study, the free radical scavenging potentials (DPPH radical and hydroxyl radical), inhibition of lipid peroxidation, and glutathione-S-transferase and antimicrobial properties of Sargassum sp. extract were ... -
Revealing monsoonal variability of the last 2,500 years over India using sedimentological and foraminiferal proxies
(Springer-Verlag, 2008)A 2-m-long, shallow-water sediment core, representing the last 2,500 years, collected from the tropical Arabian Sea from the inner shelf (22 m water depth) off Karwar (Karnataka, India) near the mouth of the Kali River, ... -
Modulation of antioxidant defences in digestive gland of Perna viridis (L.), on mercury exposures
(Elsevier, 2008)Sub-lethal effects of mercury exposure (1/10 th of LC sub(50), i.e. 0.045 mg l sup(-1)) for 5, 10 and 15 d was investigated on oxidative stress parameters and antioxidant defences in digestive gland of Perna viridis. In ... -
Nitrification in Kochi backwaters
(Elsevier, 2008)Nitrification rates, as oxidation of sup(15) N-labelled ammonium and loss of nitrite from N-Serve treated samples, were measured in Kochi backwaters during three seasons. Nitrification rates ranged from undetectable to 166 ... -
The Indian Ocean nodule field: Geology and resource potential
(Elsevier, 2008)This book briefly accounts for the physiography, geology, biology, physics and chemistry of the nodule field, and discusses in detail the aspects of structure, tectonic and volcanism in the field. The role of the ocean ... -
Identification of thermohaline structure of a tropical estuary and its sensitivity to meteorological disturbance through temperature, salinity, and surface meteorological measurements
(IEEE, 2008)Thermohaline structure of Kochi backwaters (KB) in India and its sensitivity to meteorological disturbances has been identified through measurements of temperature, salinity, and surface meteorological parameters. Silicon ... -
On the usability of `compensated temperature` output of Honeywell PPTR sensor for coastal oceanographic and limnological studies
(IEEE, 2008)Usability of the temperature output, primarily meant for temperature-compensation of the pressure output of Honeywell silicon piezoresistive precision pressure transducer (PPTR) for sea-level measurements, is presented. ... -
Detection of 12th September 2007 Sumatra Tsunami at Goa and Kavaratti Island
(IEEE, 2008)Subsurface pressure based real-time reporting and Internet-accessible coastal sea-level stations designed and established by the Indian National Institute of Oceanography (NIO) reported the 12th September 2007 Sumatra ... -
Spectral characteristics of high shallow water waves
(Elsevier, 2008)The spectral characteristics of shallow water waves with significant wave height more than 2m based on the data collected along the Indian coast are examined. It was found that the value of Joint North Sea Wave Project ... -
