An environmental perspective of the post-tsunami scenario along the coast of Tamil Nadu, India: Role of sand dunes and forests
(Elsevier, 2008)An endeavor to feel the pulse of a coast devastated by a powerful oceanographic event is made. Results of field investigations along TamilNadu, India seaside revealed that the tsunami of December 2004 demolished dwellings ... -
Marine fungal biotechnology: An ecological perspective
(Fungal Diversity Press, 2008)This paper reviews the potential of marine fungi in biotechnology. The unique physico-chemical properties of the marine environment are likely to have conferred marine fungi with special physiological adaptations that could ... -
Radioprotection against DNA damage by an extract of Indian green mussel, Perna viridis (L.)
(Begell House, 2007)This study describes the radioprotective ability of a hydrolysate prepared using an enzymeacid hydrolysis method from the green mussel Perna viridis in terms of its ability to prevent radiation-induced damage in plasmid ... -
Microsatellite development and survey of genetic variation in skipjack tuna Katsuwonus pelamis
(The Fisheries Society of the British Isles, 2008)A survey of five newly developed microsatellite DNA markers in skipjack tuna Katsuwonus pelamis revealed high levels of polymorphism in two samples off the west coast of India (Minicoy Island and Kochi coast) and one sample ... -
Intraseasonal meridional current variability in the eastern equatorial Indian Ocean
(American Geophysical Union, 2008)Intraseasonal variability in meridional current in the eastern equatorial Indian Ocean is investigated by use of results from a high-resolution ocean general circulation model. Both the simulated and observed meridional ... -
Variability of subsurface denitrification and surface productivity in the coastal eastern Arabian Sea over the past seven centuries
(SAGE, 2008)Temporal variations over the last approx. 700 years in surface productivity and subsurface denitrification in the coastal eastern Arabian Sea (off Goa, India), a hydrographically unique environment that experiences seasonal ... -
Nutrient environment of red tide- infested waters off south-west coast of India
(Springer, 2008)The bloom-infested waters along the southwest coast of India were assessed to bring about the probable cause related to the excessive algal production. Low nitrate and silicate concentrations were concomitant with slightly ... -
Recent advances in the biogeochemistry of nitrogen in the ocean
(The European Geosciences Union, 2008)Recent research has shown that marine nitrogen cycle is more dynamic, less well understood, and much more exciting than previously thought. However, despite impressive and rapid advances in our understanding of many important ... -
Why were cool SST anomalies absent in the Bay of Bengal during the 1997 Indian Ocean Dipole event?
(American Geophysical Union, 2002)The most important center of atmospheric convection associated with the Indian summer monsoon is located in the Bay of Bengal. This tendency was enhanced during the 1997 Indian Ocean Dipole (IOD) event and cool SST anomalies ... -
Ringstone anchors from Gujarat, west coast of India
(The Society for Nautical Research, 2002)The Gujarat coast, India has played a vital role in the maritime activities of India from the beginning of the Indus civilization in the Indian subcontinent and has witnessed hectic maritime activity since then. Offshore ... -
How consistent is the satellite derived SST-LHF relationship in comparison with observed values ?
(Taylor & Francis, 2008)Time series data for sea surface temperature (moored buoy), wind speed, air temperature, sea level pressure, relative humidity, short wave radiation and rainfall were collected close to the Lakshadweep islands for five ... -
Retrieval of sea surface humidity and back radiation from satellite data
(The Indian Society of Remote Sensing, 2007)The paper presents a procedure and a software package to compute the sea surface humidity and atmospheric back radiation over the sea from satellite data. These parameters play an important role in air-sea exchange of heat, ... -
Surface layer temperature inversion in the Bay of Bengal
(Pergamon, 2002)Surface layer temperature inversion occurring in the Bay of Bengal has been addressed. Hydrographic data archived in the Indian Oceanographic Data Center are used to understand various aspects of the temperature inversion ... -
Validation of ERS-1 and high-resolution satellite gravity with in-situ shipborne gravity over the Indian offshore regions: Accuracies and implications to subsurface modeling
(Taylor & Francis, 2007)Geoid and gravity anomalies derived from satellite altimetry are gradually gaining importance in marine geoscientific investigations. Keeping this in mind, we have validated ERS-1 (168 day repeat) altimeter data and very ... -
Soft and hard computing approaches for real-time prediction of currents in a tide-dominated coastal area
(IMechE, 2007)The prediction of tidal currents in the coastal region on a real-time or online basis is useful in taking operation- and planning-related decisions such as towing of vessels and monitoring of oil slick movements. Currently, ... -
Modulation of antioxidant and biotransformation enzymes in the gills of Perna viridis (L.) exposed to water accomodate fraction of diesel
(IOS Press, 2007)Investigations on the effect of oils on the oxidative stress and antioxidant molecules in gills of Perna viridis were carried out under controlled laboratory conditions. For this purpose water accommodate fraction of diesel ... -
Luminescence chronology of a second millenium BCE settlement near Porbandar on the Gujarat coast, India
(2007)An onshore excavation at Bokhira (Porbandar) on the Saurashtra coast has revealed a late Harappan settlement dating back to the early 2nd millennium BCE. Four trenches were dug in an agricultural land where an occupational ... -
Archaeological sites on the Indian Ocean Rim - A growing database
(2007)This section is designed to act as a plafform for reporting explored and excavated sites of all periods located along the Indian Ocean rim. The Indian Ocean is broadly defined It Includes the Red Sea, Gulf of Aden, the ... -
Offshore limit of coastal ocean variability identified from hydrography and altimeter data in the eastern Arabian Sea
(Pergamon, 2002)In this communication, we describe a hitherto-unknown offshore limit to the coastal ocean variability signatures away from the continental shelf in the eastern Arabian Sea, based on hydrographic observations and satellite ... -
