摘要

A large-scale nodule collection test at ocean was conducted in 1997 at the end of a Japanese national R&D project of manganese nodule mining system. The collector passes were observed by a ROV, a side scan sonar, and a towed seafloor observation camera system for the post-test evaluation. Preliminary analyses of the results are introduced in the paper. Exact locations of the passes were recognized from the side scan sonar data. Many qualitative data such as soft landings, stick-and-slip movement, and smooth take-off of the collector were obtained from the ROV observation. Very important quantitative data such as settlement of collector sledge, volume of recovered nodules and sediments, and extent of resedimentation were measured from seafloor photos taken by the camera system.
