Ambient Noise in the Western Gulf of Mexico.

Abstract

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 dB//1 micro Pa/sq root(Hz) with the slightly higher levels at the SOFAR channel axis. Overall median levels were 77-80 dB//1 micro Pa/sq root(Hz). These levels are lower than the 85 dB levels for the Atlantic near Bermuda. (Author)
