Thermal layers?
 

It seems that the thermal layers that I pass through are always around 200 to 220 feet no matter what waters I am in or what climate is like. Plus the report sometimes comes when i am on the surface so it must be a bug. Any of the mods address this issue?

Hard coded on the thermal layers I believe. Some have tried to work with it but no success. If you save near port, the crew will call it out. Eventually they stop.

Well there was a mod that you could run which set the thermals. Cant remember if it was by season or what but i think you might have had to run it every time you wanted to change.

I find it varies depending on the time of year, and where you are in distance from the equator. I've seen as shallow as 140 ft, and as deep as 250 ft. But again, location and season seem to dictate the depth it is at for a particular area.

I am not sure how effective these layers are in this game. Sometimes i stay at 100 feet or so at all stop with silent running on and the escorts never seem to detect me until i put a fish down their throats...:D

Oh they vary alright, I remember hunting for one, when it started getting down to 240 feet we were starting to sweat it.

Ive seen them as shallow as 110 feet.

Dang! At 110ft, that should really throw their aim off.

Some thermal layer information from USS Drum's war patrol nine:

Thermal layer actually a misnomer
 

The "Layer" often referred to simply using tempature and in the war that is partially correct. There are three things that effect the Sound Speed Profile Temperature Salinity and Pressure. Typically we deal with temperature but in areas near rivers of monsoon season salinity definnetly has an effect - we can feel it even today in our SSN's. What you are actually looking for is the maximum sound speed in water and to get below that when evading skimmers. IF significant enough it will create a shadow zone which can make detection of a sub damn hard. Most signifcant layers occur above around 400 feet. Too bad the game does not produce a display that either shows just temperature of the Sound Speed Profile.
By the way I have seen them from 270 to 80 feet so far.

On the same patrol off Kisku it was at 90 feet and off Hokaido it was 160 feet.

The depth of the layer appears to be directly proportinal to how quickly you need to reach it :rotfl:

I don't think the technology existed to produce an electronic sound speed profile on demand in WW2.......Knowadays they typically launch a probe for that in order to gather telemetry.........

They did have bathymerographs...but that was about it on fleet boats.......

Seems like, lately, I can't find a thermal to save my a$$.

:up:

Its there may be way down there though :|\\

And that's usually when you need it most!:rotfl:
