深海生態系の評価と影響評価

摘要

Deep-sea mineral resources is anticipated a big potential to produce significant wealth and economic growth in region or nation level, while there is no practical case of commercial based seafloor mining in deep-sea environments yet. The impacts or effects from deep-sea mining activities can be estimated from the case studies of natural disasters such as seafloor volcanic explosions and seismic change of seabed, or man-made disturbance for example ocean drilling expeditions. The developments of survey method on deep-sea environments and protocol for Environmental Impact Assessment (EIA) are conducted under multidisciplinary approaches.
