Surface-Duct Sonar Measurements (SUDS I - 1972) Oceanographic Measurements. Volume I. Instrumentation, Data Reduction Procedures, and Accuracy Analysis.
Abstract
During 9-24 February 1972 a series of 18 propagation loss experiments were conducted in three deep-water areas located southwest of San Diego, California. These measurements were designed to measure near-surface continuous wave (CW) pulse propagation losses and propagation losses for explosive sources out to ranges of 45 kyd and to obtain detailed supporting environmental measurements. Measurements were made at CW frequencies of 0.4, 1.0, 1.5, 2.5, 3.5, and 5.0 kHz. The explosive measurements were analyzed at 0.40, 0.63, 1.00, 1.60, 2.50, 3.15, 5.00, and 10.00 kHz. This is the third in a series of three NUC technical Papers reporting the results of these measurements. This report contains the supporting environmental measurements made during the four acoustic stations. It consists of five volumes. Volume I discusses the instrumentation used to make the required environmental measurements, the data reduction procedures, an accuracy analysis of the final measurements, and the method of reconstruction of the experiment track charts. Volumes II-V contain the environmental measurements applicable to each propagation loss run. (Author)
