Although these protocols may be slightly different from those
required for deep-sea mining, they could be modified for environmental
impact assessment studies for deep-sea mining. However, none of them
includes a protocol for environmental parameters in the benthic
environment, which is expected to be affected the most in case of deep seabed
mining, as the minerals occur on the surface of the seafloor.
2. Procedures suggested by NIO (India)
Outlines of procedures adopted or recommended by scientists
working on environmental impact assessment of deep-sea mining at NIO
are given in the three following tables in this chapter and in appendix B at
the end of this volume.
