Re: A Question for Peter Johnson

My interest is only that I am curious. I HAVE extensive experience with both SOSUS and Marine geophysical data. I do not want special access just wondered if the time series could be viewed. I have no axe to grind. I have admired your work for a long, long time. Thank you for your service.

Can the surface and bottom reflection be recognized in the series?

Re: A Question for Peter Johnson

Reflections are not present nor would they be expected at ranges greater than about 5-10 times the water depth, (11,100 ft), especially from the bottom which was ooze: lots of absorption, poor reflecting surface. Range from the wreck-site to hydrophone A was 821 nm, 4.7 nm further to hydrophone D.

Re: A Question for Peter Johnson

My question was the main battery explosion and what was observed at distance from the surface reflection which has a higher RC.
