"Water density"?

But water is not compressable; it is always the same density, however high the pressure.

???


Saline density?
I thought water density was 1g/ml and the water+salt( usually in sea) is 1,03g/ml. I think he was trying to say the density is not the same for (water+salt) because it depends on the weather and other factor like the concentraion of salt........

You are correct. A strong, fresh water source, ie rain, river etc, will lower the the density or specific gravity of sea water. It dilutes the concentration of solids. You are adding more volume than mass. That along with temperature (colder is denser) is the reason for thermal layers. I could get a little more detailed but my eyes are getting a bit fuzzy.....

Well thanks RP. Science has always been an amateur hobby of mine, would have pursued it academically but I hate advanced mathematics. Just explain the theory to me and I can sort it out in my head. Once you start with V x 7/RS - t2, I get dizzy. But I have to warn you, I'm in the "global warming is a natural event camp!"

I wish they could model the ineffectiveness of asdic at high speeds and after depth-charging in GWX. I fear it's hard-coded though. Sure makes things a lot harder.
