Formation of genotoxic nitroPAH compounds in fish exposed to ambient nitrite and PAH
(Oxford University Press, 2006)
Mutagenic nitrated polycyclic aromatic hydrocarbons (nitroPAHs) have been known to arise in the environment through direct emissions from combustion sources and nitration of PAHs, primarily in the atmosphere. Here we report ...
Biogeochemistry of the North Indian Ocean
(Indian National Science Academy, 2006)
Biogeochemistry is a subject wherein geochemical and biological processes occurring in the upper layers of the Earth, including atmosphere, are studied together. Many of the climatically important gases influencing the ...
Climate fluctuations of tropical coupled systems — The role of ocean dynamics
(American Meteorological Society, 2006)
The tropical oceans have long been recognized as the most important region for large-scale ocean-atmosphere interactions, giving rise to coupled climate variations on several time scales. During the TOGA decade, the focus ...
Corroded planktic foraminifer (Globorotalia menardii) in the southern Bay of Bengal sediment trap sample of February 1992
(Geological Society of India, 2006)
Planktic foraminiferal studies from the southern Bay of Bengal (SBBT) indicate the presence of corroded specimens of Globorotalia menardii in the deep trap at a depth of 3011 m during February-March 1992. Strangely, all ...
Impact of sea breeze on the wind-seas off Goa, west coast of India
(Indian Academy of Sciences, 2006)
After withdrawal of the Indian Summer Monsoon and until onset of the next monsoon, i.e. roughly during November-May, winds in the coastal region of India are dominated by sea breeze. It has an impact on the daily cycle of ...
Onshore and near shore explorations along the southern Tamilnadu coast: With a view to locating ancient ports and submerged sites
(Sharada Publishing House, 2006)
Tamilnadu coast is dotted with several ancient ports. An onshore exploration was carried out along the southern Tamilnadu coast and located several medieval ports near Nagarcoil and in Rameswaram island which include Puttan ...
Ecotoxicological effect of grounded MV River Princess on the intertidal benthic organisms off Goa
(Elsevier, 2006)
The ecotoxicological effects of oil spill from the grounded vessel MV River Princess on the intertidal benthic organisms of Sinquerim–Candolim beach at Goa, India were investigated. An intertidal expanse of 1 km on either ...
Nitrogen transformations as inferred from the activities of key enzymes in the Arabian Sea oxygen minimum zone
(Elsevier, 2006)
Vertical distributions of the potential activities of some key enzymes mediating nitrification and denitrification were investigated within the oxygen (O2) minimum zone of the Arabian Sea at a number of locations between ...
Atmospheric forcing on the seasonal variability of sea level at Cochin, southwest coast of India
(Elsevier, 2006)
The seasonal cycles of some atmospheric parameters at Cochin (southwest coast of India) have been studied with a specific emphasis on the role played by them in forcing the seasonal sea level. Equatorward along-shore wind ...
Surge ammonium uptake in macroalgae from a coral atoll
(Elsevier, 2006)
Surge (non-linear) uptake of ammonium, measured by incorporation of 15N, was investigated in three species of macroalgae (Ulva lactuca Linnaeus (Chlorophyta), Soliera robusta (Greville) Kylin (Rhodophyta) and Dictyota ...
