Certainly the towed comms buoy seems a reasonable approach, given the limited depth of dive, and
assuming this doesn't create issues. It also allows easy recovery on failure. Disguise it as a robot seagull?

I've also been working on a similar project (untethered underwater vehicle) and have stumbled on a few acoustic modem options. This acoustic modem seems to be the cheapest (it's still about $1500 for each end - $3000 for a set):

It's not a transparent serial link so you have to send data with a set of commands. There is a Python library but no Arduino library. There is a description of protocol with some examples:

I hope that helps!
