Cool, thanks again Dr.Sid. I think I've pretty much got it now and yes, the sharp edges in DW's hydroacoustic model has always annoyed me, though not quite as much as some other game issues. I also wish there was a way to set the layer depth in the mission editor or at least a way to change an AI sub's depth based on layer depth. It would have been a valuable feature for mission designers.
On a slightly different note, I seem to remember reading somewhere on this forum that the SOFAR channel is modeled in DW. Is this really true? If so, I would assume the scenario SSP has to be set to convergence zone for it to work cause surface duct just seems to have a linearly negative thermocline from the layer all the way down. I would guess that a sub would only be able to reach SOFAR depth in pretty high latitudes, but I'm not sure, it might still be to deep even near the poles.
Also, are there any other major acoustic effects I should know about in DW in any of the three SSPs?
