Top down control of post-upwelling waters off Trivandrum: Indications from variability in DMS(P)
(Centre for Ocean and Environmental Studies, New Delhi, 2012)
Coastal upwelling is known to bring nutrient rich bottom waters to the surface. This change in chemistry triggers a series of cascading effects on the trophic levels of coastal ecosystems. Phytoplankton, besides being ...
Assessment of viability in the bacterial standing stock of the Antarctic Sea from the Indian side
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2001)
During the austral summer, the bacterial population along the cruise track extending from 70 degrees S and 18 degrees E to 30 degrees S and 35 degrees E are examined. During the cruise, three distinct fractions of the ...
Cobalt immobilization by manganese oxidizing bacteria from the Indian ridge system
(Springer, 2011)
Co immobilization by two manganese oxidizing isolates from Carlsberg Ridge waters (CR35 and CR48) was compared with that of Mn at same molar concentrations. At a lower concentration of 10 mu M, CR35 and CR48 immobilized ...
Multidisciplinary investigations exploring indicators of gas hydrate occurrence in the Krishna–Godavari Basin offshore, east coast of India
(Springer, 2009)
Some main results of multidisciplinary investigations carried out within the framework of the Indian National Gas Hydrate Program in 2002–2003 in the Krishna–Godavari Basin offshore sector, east coast of India are reported, ...
Marine drugs from sponge-microbe association - A review
(Molecular Diversity Preservation International, 2010)
The subject of this review is the biodiversity of marine sponges and associated microbes which have been reported to produce therapeutically important compounds, along with the contextual information on their geographic ...
16S rRNA-based bacterial diversity in the organic-rich sediments underlying oxygen-deficient waters of the eastern Arabian Sea
(Springer, 2011)
The eastern Arabian Sea has a unique and permanent oxygen minimum zone (OMZ) that extends along the western continental margin of India. The sediment below this region is rich in organic matter. This study describes the ...
Microbiology and biochemistry of placer rich beach sediment: Short-term response to small scale simulated mining
(Allied, India, 2005)
In order to understand the influence of sand mining on the bacterial community of a placer rich beach ecosystem, a mechanical disturbance was simulated in Kalbadevi beach, Ratnagiri. Core samples from dune, berm, high tide, ...
Stimulation of sulfate-reducing activity at salt-saturation in the salterns of Ribandar, Goa, India
(Taylor & Francis, 2007)
In order to address the question if Sulphate Reducing Activity (SRA) ever gets arrested at salt saturation, it was measured at 0-2, 2-5 and 5-10 cm depth in sediment cores from the salt pans of Ribandar (Goa) using 35S – ...
Mathematical modeling of the evolution of a simple biological system
(India Environment Portal, Centre for Science and Environment, 2013)
As a part of teaching of physics it is common to record data on evolution of a physical system and then construct a mathematical model of the system. For example, movement of a simple pendulum can be recorded, and then a ...
Algal Bloom: Boon or Bane?
(NISCAIR, CSIR, 2006)
Algal blooms occur in response to nutrient deplete or replete conditions. Nitrogen fixing forms proliferate under oligotrophic conditions when nutrient levels are low. Replete conditions in response to upwelling creates ...
