  1. AcousticReport from the Bering SeaJeff 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

  2. Key for summary figures • Top figure • Geophysical interpretation of sound • Wind speed • black line – buoy wind • Blue line – PAL wind • Rainfall rate

  3. 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 +)
