Orbital frequencies in radiolarian assemblages of the central Indian Ocean: implications on the Indian summer monsoon
Radiolarian distribution in surface sediments and its relationships with overlying surface oceanography provided impetus for down-core faunal variation related to changes in monsoon intensity due to the Earth's orbital ...
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 ...
Intrusion of the Bay of Bengal water into the Arabian Sea during winter monsoon and associated chemical and biological response
(American Geophysical Union, 2004)
Situated in similar latitudes and subjected to similar atmospheric forcing, the tropical basins of the Arabian Sea looses fresh water due to excess evaporation over precipitation while Bay of Bengal receives freshwater via ...
Inter-annual variability of sea surface temperature, wind speed and sea surface height anomaly over the tropical Indian Ocean
(NIO, Dona Paula, Goa (India), 2000)
Being land-locked at the north, the Indian Ocean and its surrounding atmosphere behave in such a way that the ocean-atmosphere interaction over this domain is different from that over the other oceans, exhibiting a peculiar ...
Physical Oceanography of the Gulf of Aden
This thesis aims at the synthesis of various data sets (hydrography, sea levels, winds, and model outputs) to describe the circulation and water masses in the Gulf of Aden more precisely than before. The main objectives ...
Numerical modelling of tidal circulation and studies on salinity distribution in Mandovi and Zuari estuaries
The objectives of the thesis were to determine the characteristics of tidal propagation and salinity distribution in the Mandovi and Zuari estuaries using a hybrid network numerical model. A hybrid network model, consisting ...
Antibacterial Activity of 2- (2',4'- Dibromophenoxy) -4, 6 - dibromophenol from Dysidea granulose
(Molecular Diversity Preservation International, 2009)
2 - (2',4'- Dibromophenoxy) - 4, 6 - dibromophenol isolated from the marine sponge Dysidea granulosa (Bergquist) collected off the coast of Lakshadweep islands, Indian Ocean, exhibited potent and broad spectrum in-vitro ...
Abandoned Paleocene spreading center in the northeastern Indian Ocean: evidence from magnetic and seismic reflection data
Magnetic data from the northeastern Indian Ocean reveal east-west trending magnetic lineations 28 through 34, an abandoned spreading center (ASC) and part of the Cretaceous Magnetic Quiet Zone (CMQZ), which are used to ...
Productivity variations, oxygen minimum zone and their impact on organic enrichment in the sediments
(National Institute of Oceanography, India, 2007)
Marine-derived fungi as a source of proteases
(NISCAIR, CSIR, 2008)
Microbial enzymes have continued to assist diverse reactions as biocatalysts. Marine derived microbes offer a prospective resource for such enzymes. In this study thirteen fungi were isolated from marine organisms (soft ...
