Alterations in geochemical associations in artificially disturbed deep-sea sediments
(Taylor and Francis, 2005)In view of the role of sediment geochemistry in regulating the benthic ecosystem, diagenetic remobilization of dissolved constituents, bottom water redox, and regeneration of benthic fluxes, surficial sediments in and ... -
Brackishwater shrimp farming: Possible impacts on estuarine ecosystem
(University of Kerala, Kerala (India), 1998)Aquaculture has been widely accepted as a practice that will supplement the capture fishery production, besides generating various types of job opportunities for the rural population. Coastal aquaculture has been given ... -
Changes in geotechnical properties of sediments from the Central Indian Basin induced by disturbance experiment
(Taylor and Francis, 2005)During the Indian Deep-sea Environment Experiment (INDEX) conducted in the Central Indian Basin to simulate nodule mining activity, the sediments were physically disturbed, lifted from the seafloor, and then redeposited ... -
Deep-sea impact experiments and their future requirements
(Taylor and Francis, 2005)In recent years, several experiments to assess the potential impacts due to deep-sea mining in the Pacific as well as the Indian Oceans have indicated the immediate changes and restoration patterns of environmental conditions ... -
First phase monitoring studies of simulated benthic disturbance delineating movement of fine particles in the Central Indian Basin
(Taylor and Francis, 2005)Benthic disturbance due to future deep-sea polymetallic nodule mining would involve extensive sediment plume generation and resedimentation on the sea floor. In order to evaluate the effects of resedimentation on benthic ... -
Immediate response of meio and macrobenthos to disturbance caused by a benthic disturber
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The probable impact of nodule mining on benthic biota was studied by creating a benthic disturbance. During the predisturbance study in the Central Indian Basin, box core samples were analyzed for the distribution, composition ... -
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 ... -
Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ... -
Monitoring the impact of simulated deep-sea mining in Central Indian Basin
(Taylor and Francis, 2005)Monitoring of deep-sea disturbances, natural or man-made, has gained significance due to the associated sediment transport and for the ensuing alterations in environmental conditions. During the Indian Deep-sea Environment ... -
Monitoring the sedimentary carbon in an artificially disturbed deep-sea sedimentary environment
(Springer, 2012)An area of 0.6 km sup(2) in the manganese nodule field of the Central Indian Basin was physically disturbed and sediments discharged in the near bottom waters to simulate seabed mining and study its impact on benthic ... -
Record of imposex in Cronia konkanensis (Gastropoda, Muricidae) from Indian waters
(Elsevier, 1999)This study for the first time records the phenomenon of imposed in gastropods from Indian waters. The gastropods were collected from three stations located in Goa: Marmugao Harbour, Dona Paula and Arambol. Imposex was ... -
Response of sedimentary nucleic acids to benthic disturbance in the Central Indian Basin
(Taylor and Francis, 2005)Information on the response of nucleic acids (i.e., DNA and RNA) to simulated benthic disturbance was obtained from samples collected from eight sediment cores (0-10 cm) located in the Central Indian Basin (CIB). In general ... -
Rise of the dormant: Simulated disturbance improves culturable abundance, diversity, and functions of deep-sea bacteria of Central Indian Ocean Basin
(Taylor and Francis, 2005)The abundance of baroduric bacteria from nine sediment cores (0-10 cm below sea floor) was examined for their response to simulated benthic disturbance in the Central Indian basin (CIB). While the total counts of bacteria ... -
Role of mangroves in brackish water fish culture
(1992)Mangroves is a specialized marine ecosystem consisting of a group of plants growing in muddy, loose and wet soils in tropical and subtropical areas, comprising of shallow, coastal waters, deltas, estuaries or lagoons. ...
