Description
Summary:This report is an UNCLASSIFIED edition of USL Report No. 255 (confidential) dated 21 March 1955. The Project AMOS work which was carried out through the period 1 January 1953-31 December 1954 is summarized. This is a final report of the AMOS deep-water acoustic measurements, which began in June 1949. During the period covered by this report, the Underwater Sound Laboratory carried out a number of studies and analyses of AMOS data; these are included herein as Studies A through D and H through J. The major study is an analysis of sound transmission at frequencies between 2 and 25 kc based on all the AMOS data and on other data available in the literature. Propagation-loss prediction charts based on this analysis are presented as a function of certain environmental parameters. An error study of the propagation analysis is presented next. Studies of AMOS low-frequency noisemaker data analysis, ray tracing in the ocean, and bottom reflection in deep water are also presented, and a summary of Cruise TWELVE, which was completed early in this period, is included.
