Abstract:

The CHURCH ANCHOR and SQUARE DEAL Exercises were concerned with acquiring environmental acoustic data for two ocean areas. A large number of explosive signals were used to measure acoustic propagation loss. Signals were received and recorded on a number of different systems and, subsequently, processed by a number of different organizations. An examination of preliminary data disclosed a number of possible discrepancies. These included unusual features in a number of CHURCH ANCHOR propagation loss plots, different propagation loss values obtained when the same recorded data was processed at different laboratories, and propagation loss measurements made with one array significantly lower than measurements made with another system in the same general area of the SQUARE DEAL experiment, although the runs compared were for different tracks. An investigation was undertaken to investigate these matters. This document reports the results of that investigation. It was found possible to explain or correct most of the discrepancies.
