Abstract:
This is the fifth in a series 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 tack charts. This volume is a detailed report of the environmental measurements applicable to the acoustic experiments conducted during station 4, where four acoustic experiments 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 figure (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, thermistor chain, and Teletherm buoy measurements used to determine the distribution of sound speed and the locations of surface-wave measurements made by the Waverider buoy used to determine surface roughness.
