Abstract:

During the SQUARE DEAL exercise, explosive source propagation data were acquired at twelve receiver locations. Approximately fifty source events of 100 nmi to 2000 nmi extent were executed. This report deals with acoustic propagation measurements obtained from the ACODAC, SURVEY, Ambient Noise Buoy, and MABS II receivers. These system had omnidirectional receivers distributed throughout the water column. Measurements from 18 m and 91 m sources were obtained in the frequency range 25 Hz to 300 Hz.
