I would imagine that there is is an insane amount of gravitational noise from things like the planet’s asymmetry and events occurring all the way from the core to the crust, the ocean… to cut through that noise you need one big thumper.

The most obvious source of noise seems to me the fact that the submarine is moving and has therefore nonzero accelerations all the time

Most obvious would be the phase of the moon.

Thing is, you don't have to cut through the noise these days. Low energy/low bandwidth radio communication routinely sends messages below the noise floor.

Depends on you application, but if you only send some bits of information ("stocks just crashed") having a big thumper with a very known impact profile is sufficient.
