Deep Sound Deployment – Early Morning, September 1 The first instrument to be deployed was “Deep Sound.” We reported to the main lab at 5:30 a.m. and were ready to go by 7:00 a.m.
Dave Barclay, the scientist leading this part of the work, is a graduate of SIO/UCSD. His degrees are in oceanography and physics. He’s currently doing a post-doc in Newfoundland and plans to do another at Woods Hole. Dave has become an expert in acoustics. He is studying the sounds of the ocean and is particularly interested in characterizing the normal, background sounds of the sea. It’s very important to be able to do that so that any unusual sounds can be distinguished. Dave describes his instrument to one of the observers. They carefully inspect it just before deployment.
It takes three people to managing hoisting “Deep Sound” and swinging it out over the water. Hard hats and life preservers are mandatory.
The instrument was lowered into the water. At this point in the voyage, the depth of the ocean was about 8200 meters. “Deep Sound” will remain in the ocean for about 10 hours. Recovering it is scheduled for late this afternoon, at about 5 p.m.
