Ambient Noise in the Western Gulf of Mexico.
TEXAS UNIV AT AUSTIN APPLIED RESEARCH LABS
Pagination or Media Count:
A brief 12 h segment of ambient noise from the Western Gulf of Mexico for a clear, calm period has been analyzed. The receiver depths were 170 m, 370 m, and 766 m the bottom was at 3280 m. It was found that the ambient noise was dominated most of the 12 h by seismic exploration. To avoid this noise, quiet periods between seismic domination were used the median noise levels at 50 Hz were found to be around 75-77 dB1 micro Pasq rootHz with the slightly higher levels at the SOFAR channel axis. Overall median levels were 77-80 dB1 micro Pasq rootHz. These levels are lower than the 85 dB levels for the Atlantic near Bermuda. Author
