Abstract : A laboratory model Optical Settling Tube referenced in appendix 1 has been redesigned to obtain in situ settling velocity distributions in the deep ocean. A prototype instrument was constructed and tested on a HEBBLE cruise in June, 1983. The instrument functioned perfectly and in situ settling velocity distributions in the deep ocean were measured. Data listed in this report demonstrates that an Optical Settling Tube can now be used for the purpose of repeatedly measuring settling velocity distributions in the deep ocean from a moored platform.
