Abstract:

Ambient noise was measured in four deep basins of the Mediterranean Sea for three consecutive days at each station during June of 1968. Sonobuoys with hydrophones suspended at a depth of 95 feet were used to collect and transmit the data to a quiet ship several miles distant. Eight frequencies in 12-octave bands were used in the range from 16 to 800 Hz. Levels in these bands were read at 10-min intervals, sight averaged over this time, and are presented as distribution functions and average values for each station along with wind information. Environmental data such as velocity and temperature profiles, depth measurements and traffic observations are reported.
