Abstract : This letter report summarizes the work performed by CSDL and refers to technical reports, papers, and journal articles for detailed documentation. Instrumentation development for internal wave investigation and ocean deployments in direct engineering support of M.I.T. ocean science programs are described. This work entails active field programs with two advanced arrays making fundamental measurements of internal waves and microstructure in the open ocean -- the Microscale Sensing Array (MSA) and the Intermediate Internal Wave Array (IIWA). These systems were designed to complement earlier ONR-sponsored arrays: Bermuda Buoy (1970-71) and Ocean Telescope (1967-69). Theoretical and experimental investigation of techniques required for optimum interpretation of oceanographic measurements obtained from moored buoy systems are also described. This work has focused upon the basic dynamic measurement problems encountered in the above-mentioned M.I.T. program and in WHOI moored array experiments.
