There are problems with signal attenuation when using Radio waves under water. Check this link out - http://cr4.globalspec.com/thread/21392/Radio-wave-transmission-in-water (http://cr4.globalspec.com/thread/21392/Radio-wave-transmission-in-water)

So it depends on how much water your signal will have to travel through.

I also expect that you are also going to have to waterproof your own transmitter, but i doubt that will be too difficult. There is a tutorial on SoR about waterproofing electronics. Check that out. :)

The best way to transmit data is ELF....
But considering you don't have access to HARRP.... that's not an option....
A sonobuoy with an antenna on it is a good idea though... (expect you aren't going deep eehh???)
