Codename: Iceman is visually a very beautiful game. But that Sub Sequence is... brutal. The thing is - Running Silent isn't the only thing you need to do. You need to dive the sub down also and get below the cold area - and run silent, so that no heat signatures are detected.
You're referring to using the thermocline to help hide the sub's sonar signature. It's a real world tactic.
The thermocline is where the ocean's water density changes, which can act as a barrier of sorts and cause sound energy (which is what sonar depends on) to bend away. It's not fool proof by any means, but it can definitely help hide a submarine — especially when paired with silent running, which prevents cavitation thereby greatly reducing noise — from other subs or surface vessels, like frigates, destroyers, or even aircraft.
Also, since Codename: Iceman takes place during the end of the Cold War era, that means you're dealing with far more advanced torpedo technology. When a torp is fired, controllers on the sub can literally control the torpedo using a "wire" system. This enables controllers to guide the torp around noise makers, which are designed to distract torpedo guidance systems.
A torp's "wire" can be "cut" which disables direct control and makes the torp entirely reliant on its own guidance systems. Why would you want to do that? Well, submarines can only have so many active "wires" at a time, so sometimes it's worth losing a torp if it means concentrating on a new torp that has a better chance at hitting its mark.
I don't recall Codename: Iceman modelling the "wire" system, which is a problem considering the game specifically positions the player as the XO of a Los Angeles-class submarine. A Los Angeles-class sub can have four active "wires" at once.

You're right, it does a piss-poor job of informing the player, and that's a huge failing in its design. The only reason I know as much as I do is because I've studied military equipment and tactics, and played dozens of submarine simulators, all of which are far more difficult than anything presented in Codename: Iceman. The difference, however, is that you KNOW you're getting into something complex with a sub sim, whereas you don't expect the same level of complexity and required knowledge when playing an adventure game.
