Note
This paper describes several successful, ongoing science projects utilizing Harbor Branch Oceanographic Institution's (HBOI) manned submersibles. One project involved imaging natural and man-made objects near the ocean floor using a laser-line-scanning (LLS) system equipped with multiple receivers. This system was interfaced to the Research Submersible CLELIA and employed on five missions during 1996. Spectacular high-resolution black and white, fluorescence and color images were obtained.
