Chemosynthetic activity prevails in deep-sea sediments of the Central Indian Basin
(Springer, 2011)
It is hypothesized that in the deep-sea, under psychrophilic, barophilic and oligotrophic conditions, microbial community of Central Indian Basin (CIB) sediments could be chemosynthetic. In the dark, at near ambient ...
Water quality and bacteriology in an aquaculture facility equipped with a new aeration system
(Springer, 2010)
The HOBAS aeration system was tested to compare changes in environmental and bacteriological parameters in ponds growing Penaeus monodon during a single production cycle. The stocking density in the aerated pond was doubled ...
Denitrification: An important pathway for nitrous oxide production in tropical mangrove sediments (Goa, India)
(American Society of Agronomy, 2010)
Net nitrous oxide production and denitrification activity were measured in two mangrove ecosystems of Goa, India. The relatively pristine site Tuvem was compared to Divar, which is prone to high nutrient input. Stratified ...
Denitrification prevails over anammox in tropical mangrove sediments (Goa, India)
(Elsevier, 2012)
Denitrification, anammox (Anx) and di-nitrogen fixation were examined in two mangrove ecosystems- the anthropogenically influenced Divar and the relatively pristine Tuvem. Stratified sampling at 2 cm increments from 0 to ...
Microbial and biochemical alterations due to storage of deep-sea sediments under ambient tropical conditions
(NISCAIR Publications, 2016)
Response of indigenous bacteria to incubation at normal pressure and tropical temperature (28 ± 2°C), were examined in four deep-sea sediments from polymetallic-nodule fields in Central Indian Basin (CIB). Sediments were ...
Interactions between trophic levels in upwelling and non-upwelling regions during summer monsoon
(Elsevier, 2015)
Coastal upwelling is a regular phenomenon occurring along the southwest coast of India during summer monsoon (May–September). We hypothesize that there could be a shift in environmental parameters along with changes in the ...
A global census of marine microbes
(Wiley-Blackwell, 2010)
In this chapter we provide a brief history of what is known about marine microbial diversity, summarize our achievements in performing a global census of marine microbes, and reflect on the questions and priorities for the ...
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)
Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ...
Monsoonal variability in abiotic parameters in coastal waters off Trivandrum evokes press and pulse response in biotic variables
(Centre for Ocean and Environmental Studies, New Delhi, 2012)
Trivandrum Coast experiences coastal upwelling during south west monsoon, which is accompanied by abiotic changes in physio-chemical parameters. The resultant biotic responses could range from an instantaneous pulse to a ...
Deep-water chemosynthetic ecosystem research during the Census of Marine Life decade and beyond: A proposed deep-ocean road map.
(PLoS, 2011)
The ChEss project of the Census of Marine Life (2002-2010) helped foster internationally-coordinated studies worldwide focusing on exploration for, and characterization of new deep-sea chemosynthetic ecosystem sites. This ...
