I have a dumb idea; how hard is it to add a location tracker to these kind of subs? Does the high pressure make this incredibly hard to add?

How would you track your location underwater? What's your reference?
They don't have any GPS signal down there...

Its not the pressure, but the fact water blocks radio waves. Submarines can’t get GPS signals or transmit their location. Submarines have to rely on other means such as IMUs to track their own location.

They have another ~30 hours of air. The biggest hope is that they are not terribly deep trapped near the surface and can be located in that time.
How could they be trapped "near" the surface? That would require the sub to maintain buoyancy precisely, which seems unlikely without active systems.
As I understand it, the vessel is not able to surface on its own. At its most buoyant, a small amount of the sub will emerge from the water, and that weight will push it back down, so the vast majority of the sub is underwater. This bobbing, which depending on waves can have a small amount or none of the sub above water at any time, would make them hard to detect but easy to retrieve if they were located.

With sonar. The submarine doesn't have to locate itself, it just needs to be active pinging and it can be triangulated.
Radio doesn't work underwater, but sound actually travels incredibly far (hence why military subs go all out with noise reductions).
Edit: I mean the real question is why the hell does this thing not have some type of system like this already? You know the upfront expected dive time, so set a couple of noisemakers on the exterior hull to go off after you exceed it.

I am not a marine noise expert, but it’s my understanding that noise transmits horizontally underwater way better than vertically. Since this sub is going really deep, getting the pings to go ‘up’ to a meaningful degree is going to be difficult.

Just add a line. It's only 2 miles.

Imagine being so close yet still not able to escape the vessel. I don't know what is standard for subs, but it strikes me as particularly terrifying that they have no way to open it from the inside.

#20I am not even sure why we are looking for them, I don't think there is any way to setup rescue equipment that can go low enough to help them and drag that submersible out of the water before they would run out of oxygen.
