Acoustic Report from the Bering Sea
Jeff NystuenApplied Physics Lab
• Sound summaries from the PAL deployed at Site 2 during the summer of 2004
• Acoustic measurements of wind and rain• Detection of ships• Probable detection of marine mammals
Key for summary figures
• Top figure– Geophysical interpretation of sound
• Wind speed– black line – buoy wind
– Blue line – PAL wind
• Rainfall rate
Key for summary figures
• Bottom Figure - Sound levels at 2, 8 and 20 kHz- Detection of ships (red and orange)- Detection of rain (blue triangles)- Detection of peak between 300 Hz and 3 kHz
(Possible whale call (black triangle)
- Transient sounds detected (black x and +)
