Special Sessions — Acoustical Oceanography Committee

 Upcoming Meeting: 

 Session 151,  June 2006 — Providence, RI

• Exploitation of sound by marine mammals:
  Marine mammals are sophisticated users of sound, both self generated and the surrounding ambient. This session features research that shows examples of this behavior.
  
  
• Ultra-low and low frequency marine seismo-acoustics:
  Focus is on acoustic sensing of natural seismic phenomena such as tsunamis, earthquakes and ocean storm events.

 Past Meetings: 

Session 150, Fall 2005 — Minneapolis, MN

• Ocean ecosystem measurement:
  Use of acoustics to determine the abundance, distribution, and behavior of marine organisms in relation to their environment.
  
  
• Inversion using ambient noise sources:
  Inversion techniques for estimation of ocean environments using natural and man-made noise as sound sources.
  

Session 149, Spring 2005 — Vancouver, BC

• Riverine Acoustics
   
  
• Acoustics and ocean observatories:
  Science results and development efforts related to sustained ocean observing, in all fields from physics to biology.
  

Session 148, Fall 2004 — San Diego, CA
