CHURCH OPAL Exercise, ACODAC Measurements, Ambient Noise and Associated Propagation Factors as a Function of Depth and Wind Speed in the Deep Ocean
TRACOR INC ROCKVILLE MD
This report gives preliminary results of ACODAC measurements made during CHURCH OPAL exercise, sponsored by LRAPP. Wind generated ambient noise spectra are presented as a function of wind speed over a frequency range of 10 to 500 Hz. The variation of ambient noise generated by distant shipping as a function of depth at the measurement site is given. A number of ship source level estimates as a function of frequency are presented.
