Deep Sound Channel

[Kondado]

Hello all,

some days ago I found a very interesting article in PDF talking about the deep sound channel, halocline layer, with graphs including those mentioned and the sounds different animals emit and so on...

I don't seem to be able to find it again and I didn't store it onto my pc

I found similar articles but none as good as that first one I found. I'm not sure from whom it was but it was edited in a high quality style ... Most of it was in black&white but it was very informative...

Any help is appreciated (although I haven't got much hope ...)

Cheers

I found a document SIMILAR to that one I first read

I actually want to find the original document which is from where the graphics were copied. It seems that what I am searching for was written and/or published by the US Navy.

This one is the pdf which uses the graphics

(can't post full URL)

PD: I'd be satisfied with finding the original high quality pictures shown on above mentioned document seen on pages number 11 (deep sound channel graph) and on page number 30 which shows the frequencies of different animals, noise, etc.
