Monitoring effects of simulated disturbance at INDEX site: Current status and future activities
(International Society of Offshore and Polar Engineers, 2003)
During the Indian Deep-Sea Environment Experiment (INDEX), greater than 6000 cu.m of sediment was resuspended 5 m above seafloor. Data collected from deep-towed photography, sediment traps, sediment coring and CTD operations ...
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 ...
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 ...
Distribution of manganese nodules, rocks and sediments in the Central Indian Ocean Basin: Factors influencing performance of mining system
(Publ. and Inf. Dir., New Delhi, India, 1994)
Manganese nodule abundances in the Central Indian Ocean Basin (CIOB) as noted from seabed photographs (nil to 18.4 kg/m sup(2)) and grabs (nil to 21.5 kg/m sup(2)) are variable. The relative abundance varies from zero to ...
Indian deepsea environment experiment (index): Achievements and applications
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)
Significant results have been obtained from an extensive database generated on water column and benthic baseline conditions. Seafloor surveys have resulted in selection of suitable test and reference areas, and in ...
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 ...
Seafloor and sediment characteristics in INDEX AREA
(Metal Mining Agency of Japan, 1997)
Seafloor surveys and sediment sampling during the INDEX (Indian Deep-Sea Environmental Experiment) studies in the Central Indian Basin, resulted in identification of Test and Reference Areas, as well of establishment of ...
Influence of seabed topography on the distribution of manganese nodules and associated features in the Central Indian Basin: A study based on photographic observations
(Elsevier, 1993)
The distribution of manganese nodules and associated rock outcrops and sediment cover in the Central Indian Basin (10 degrees-16 degrees S, 73 degrees-82 degrees E), were studied from seabed photographs in relation to ...
Benthic disturbance and monitoring experiment in the Central Indian Ocean Basin
(Int. Society of Offshore and Polar Engineering, Colorado, USA, 1997)
Environmental impact assessment studies for deep-sea manganese nodule mining have been initiated in the Central indian Ocean Basin since 1995. As a part of the first phase for collecting the benthic baseline data, echosounding, ...
Effect of sediment-water interface 'boundary layer' on exposure of nodules and their abundance: a study from seabed photos
(Geological Society of India, 1989)
The results obtained from seabed photos and boomerang grab samples reveal a striking similarity in distribution patterns of size classes of polymetallic nodules. Due to partial sediment cover, there is a 'fractionation' ...
