Thermograph in Silent Hunter IV

Well, check out the Wiki article on bathythermographs:

http://en.wikipedia.org/wiki/Bathythermograph

Here's a chart from the USS Drum's 9th war patrol:

At a certain depth a large temperature change (thermocline) could be noticed if you watched the bathythermograph.

The photo I posted in my previous post is the bathythermograph in the USS Drum, and it's still showing the outside temperature today.

When scuba diving (especially in the Great Lakes) you can sometimes "see" a thermocline. Obviously I'm not talking submarine depths here but rather 35 feet or 60 feet or more depending on the conditions. It's hard to describe but it's kinda like a shimmery "current" and is one of those things that you see better if you don't look right at it (underwater "northern lights", LOL). There is also a noticeable change in temperature.
I suppose if you poured hot water into a large tub of cold water you'd briefly see the effect I'm trying vainly to describe.
