Thermal Layer
In SHIV the boat passed through a thermal layer along with salination levels this distorted the position of the boat. Was this information available to the Germans during the war as it would appear it was to the Yanks??? If it was, is it possible to mod this into the game??

They knew about it however there were no reliable instruments in that era that would magically tell you when you were passing through it.
The call of 'passing thermal layer' is strictly hollywood I'm afraid.

The Americans had an instrument that did this by measuring the water temp outside the hull.
http://en.wikipedia.org/wiki/Bathythermograph It was included in SH1, but I forget if it was in SH4 or not. No word in the article if German subs had a similar instrument, but I doubt it. |

In SH4 it was represented by the sound file "Passing thermal layer", I believe.
In one of my SH5 videos, the beta still had that sound file in the game. Since U-boats were unable to know when and if they were passing a TL, I removed the sound file before making the video. Thankfully, the dev team also removed it before the game was released.

Are you sure they didn't remove thermal layers entirely? They hardly sound arcadey.

thermal layers are in the game. I just don't think there's any way to know if you pass though one.

-Thermal layers exist in the game. At least in the files that control AI detection.
- The effect Thermal layers can be turned off. - The germans knew thermal layers existed, but had no way of detecting them. - Thermal layers were too deep and unreachable in the atlantic, so the topic is kinda moot where the battle of the atlantic is concerned. |

"North Sea, in the Skagerrak and Kattegat, Straits of Gibraltar, Gulf Stream, near mouth of rivers"
Sounds quite relevant to me, ..i mean that info is from a Kriegsmarine Kadetten HAndbuch. Missions in Bergen etc come to mind and the North sea ,well sounds like the region you could occasionally encounter some subs. |

In one of my last games I had at least the feeling of passing a thermal layer. Because I'm relatively new to subsims I kept the map informations on to get a feeling of distances, enemy behavior and such. So I was on the run. The destroyer came closer and closer and I tryed to get deeper and when I was diving at about 135 meters the sonar markings of the destroyers on the map became very small. I was just wonderig if that has been the effects of thermal layer or if I overlooked something in game mechanics such as deeps range of the sonar. I also forgot to try out if theres any difference with my own sonar. 135 meters isn't very deep :/
so I don't know if it's physically possible of having a thermal layer there. The ony thing I know is that there's beside other thermal layers a so called convergence zone at 3000 feet (about 900 meters) where the temperture is steady below, but since you are not able to go so deep during WWII we can just neglect that. |

In sh4 the dd's would do a little trick of one driving around near flank banging away with the asdic while the other sits motionless and listens. Neat trick that was

Thermal layering (or salinity) is dealt with in the U.Kdt.Hdb. (U-boat Commanders Handbook) that were written by a collection of U-boot commanders during the first year of WWII.
Its located under item 57) citation: Quote:
