Book Description
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).

Book Description
This is the third of five volumes describing the environmental measurements made during the SUDS I experiments. 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 reconstruction of the experimental track charts. This volume contains a detailed report of the environmental measurements applicable to the acoustic experiments conducted during station 2, where four propagation loss runs were completed. Figure 1 shows the location of the experiments and the track of the source ship. Source ship speed was 3 knots for all runs. The detailed environmental data for each propagation loss run are summarized in the form of charts, plots, and tables in the appendices. Each appendix presents the same kind of data in the same sequence for all propagation loss runs. Additions and omissions are made as appropriate for the run described. Thus the first appendix figure (i. e., A-1, B-1, etc.) is a chart showing the locations of source and receiver ships, selected propagation paths, and wind velocity. The second figure (A-2, B-2, etc.) is a chart showing the locations of XBT and thermistor chain measurements used to determine the distribution of sound speed present during the acoustic experiments and the identification of the ship making the measurement.

This volume contains a detailed report of the environmental measurements applicable to the acoustic experiments conducted during station 1, where five propagation loss runs were completed. Figure 1 shows the track of the source ship during these experiments. Source ship speed was 3 knots for runs 1-4 and 6 knots for run 5. The detailed environmental data for each propagation loss run are summarized in the form of charts, plots, and tables in the appendices. Each appendix presents the same kind of data in the same sequence for all propagation loss runs. Additions and omissions are made as appropriate for the run described.

Volume I describes the instrumentation used to make the propagation loss measurements and the data reduction procedures. Volumes II-V are detailed reports containing a summary of the environmental measurements, plots of propagation loss versus range, and comments pertinent to the specific propagation loss run.
