So far as the microphones themselves are concerned, one very good option 
would be to used the Knowles WP-3502 capsules, which are miniature hearing 
aid capsules.  They are specified as being able to withstand immersion in 3 
m. of water.  They don't have the lowest noise, but then I don't think that 
will matter in your application.  The capsules are available from Digikey 
for about $40.
