Abstract : The study is part of a continuing program of underwater sound propagation research called project MIMI. The report covers reception and processing and a limited number of analytic comments. The test timing and duration were chosen to allow closer examination of propagation anomalies previously observed during the early winter and to obtain continuous data on an entire lunar-tide cycle (approximately 28 days). The major objectives were to provide data for the design of more extensive experiments and to test the programs and techniques associated with the LINC-8 computer. Signal processing was designed to yield both multipath information and data on anomalous path conditions. The principal success of the study has been in the improvement of processing programs and experiment design. (Author)
