4.2 Environmental Impact Assessment Study

The comprehensive study initiated in 1996-97 to assess the environmental impact of large scale deep seabed mining activity continued with disturbance of benthic ecosystem, simulating mining operations in identified site in CIOB in 1997-98. The observations of physical, chemical, biological & geological parameters were made at test and reference site. Plans are finalized for monitoring recolonisation effect with deep tow colour video photography, chemical parameters with CTD, and biological & geological parameters with core samples. Documents on `Baseline study on ocean currents in CIOB', `Baseline environmental conditions on the physical, biological, chemical and oceanographic parameters in CIOB' and `Benthic disturbance and impact assessment studies in the Indian Pioneer Area' were prepared on baseline benthic conditions.
