REPORT ON THE STATUS OF PROJECT AMOS (ACOUSTIC, METEOROLOGICAL, AND OCEANOGRAPHIC SURVEY)

Abstract

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.
