Report on the Status of Project AMOS (Acoustic, Meteorological, and Oceanographic Survey) (1 January 1953 - 31 December 1954)
Abstract
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 deepwater 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 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 classified and nonclassfied 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. The AMOS propagation analysis then is used to construct lateral range curves for hull-mounted, echo-ranging sonars at various frequencies and various figures of merit for submarines at periscope depth and at the depth which is best for avoiding detection. A comparison is made of measured and predicted ranges for a number of sonar systems. Studies of AMOS low-frequency noisemaker data analysis, ray tracing in the ocean, and bottom reflecion in deep water are also presented, and a summary of Cruise TWELVE, which was completed early in this period, is included.
