science and as a demonstration of NOAA/Navy cooperation. In 

 fact, this collaboration has been a stimulant for NOAA to seek 

 other uses of the lUSS. 



The PMEL project has evolved over several years to where it 

 now uses a realtime data link from the Navy to NOAA's facility in 

 Newport, Oregon. There, the raw acoustic data are processed to 

 detect signals from volcanic and seismic activity. In a dramatic 

 success, this link detected and located a below the surface 

 volcanic eruption just as it started a few weeks ago. A research 

 ship in the area was alerted and sent to the location. It was 

 able to collect rare water samples at the event. This type of 

 quick response to a rare event, and the monitoring of more 

 frequent hydrothermal venting events would only be practical with 

 dual use of the lUSS. 



Other significant lUSS applications have been proposed as 

 well. These include: 



• assessing global warming by measuring bulk ocean 

 temperature using acoustic tomography techniques; 



• monitoring marine mammal (e.g., endangered whales) 

 behavior, migrations, and assessing population sizes and 

 distributions ;
