Impacts on surface productivity during sediment dispersal experiment in Central Indian Basin
(Taylor and Francis, 2005)
It is anticipated that in the case of mining of marine minerals, sea floor sediments will be brought up along with the mineral ores and discharged on the surface. These nutrient rich sediments would create a set of different ...
Candidates for the development of consortia capable of petroleum hydrocarbon degradation in marine environment
(Fostering International Coop. Res., UK, 1995)
Bacteria and yeasts from different niches of the tropical Indian waters were screened for their hydrocarbon degrading potential using 1% w/v in artificial seawater over a period of 6 days. About 20% of the 75 bacterial and ...
Marine organisms and their adaption - Adaptions solve the challenges of existence in the sea.
(Centre for Environmental Studies, 2009)
Marine organisms exist in an ever-changing environment. The physical environment within the ocean varies with the availability of light, oxygen, food resources, pressure and temperature. This variation in the physical ...
Denitrification prevails over anammox in tropical mangrove sediments (Goa, India)
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 ...
UV radiation and primary production in the Antarctic waters
(Department of Ocean Development, New Delhi, 1997)
A profiling underwater radiometer was used for the first time in the waters around Indian Antarctic Station (70 degrees 46 minutes S and 11 degrees 44 minutes E) in the summer of 1994. The profiles include natural fluorescence ...
Manganese oxidation by bacterial isolates from the Indian Ridge System
The abundance and activity of culturable manganese-oxidizing bacteria were assessed from near-bottom water samples of the tectonically active Carlsberg Ridge. Retrievable counts as colony forming units (CFU) on dilute ...
The September 2004 stench off the southern Malabar coast - A consequence of holococcolithophore bloom
(Indian Academy of Sciences, 2005)
During the third week of September 2004, particularly on 16th and 17th, an unusual and strong stench was reported from the coast at Kollam and Vizhinjam in Kerala (India). Local dailies reported that over 200 children, ...
Synergy in Sulfur Cycle: The Biogeochemical Significance of Sulfate Reducing Bacteria in Syntrophic Associations
(National Institute of Oceanography, Goa, 2004)
Role of bacteria in DMS(P) cycle
Dimethyl sulphide (DMS) was reported in oceanic waters by Lovelock et al., (1972). Its precursor Dimethyl sulfoniopropionate (DMSP) is ubiquitous in the euphotic zone especially in regions dominated by phytoplankton. The ...
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 ...
