Abstract

Submersible studies of the preferred cable route were conducted in order to define the safest cable path for the deep water power cable. Specific study objectives were as follows: (1) Investigate potential problem areas for the cable route due to geological roughness identified in previous geophysical bottom roughness surveys; (2) Determine width characterized by a smooth ocean floor and check for obstacles in the narrow gap regions on the Maui Slope; (3) Provide data packages consisting of the video, still photographic and environmental data taken from the submersible for each dive; (4) Compile a biota summary (survey of living animals) as a precursor for a formal environmental impact study; and (5) Prepare a final report summarizing the data obtained in the form of geologic maps of the areas of interest, and an interpretation of the detrital dynamics of the ocean floor.
