Abstract : The U.S. Naval Oceanographic Office used the Westinghouse submersible DEEPSTAR-4000 for 13 dives during October and November 1967. Marine geology, biology and the physical properties of the water column were studied on the 10 deep dives of this series. These dives were accomplished along the east coast of the United States and in the Caribbean. Great similarities in the bottom features at widely separated sites as well as dissimilarities in adjacent areas are particularly noteworthy. During this operation DEEPSTAR-4000 was evaluated as a Deep Oceanographic Survey Vehicle (DOSV). The lack of an all-weather capability and the rather limited payload hampered this study but the overlapping fields of the viewports and the ability to operate in very close proximity to the bottom regardless of terrain, are desirable features that should be included on any future DOSV.
