There be whales here....or Flipper.
 

Though I haven't read it here yet. I am patrolling in and around the eastern waters of of Scotland (U29 type VIIB) 100km SE of Scapa Flow when I hear the weirdest thing on the Hydrophones. It sounded like a drill from the dentist. Very high pitched and it oscillates...just like when you're getting your teeth drilled.:88)

Am I to understand that SHIII (I am using GWX3) has biological sounds? Dolphins and whales, etc? They seemed to move fast. I was taking readings every 5 minutes and the source moved quite a bit. I'm thinking Flipper and friends...:hmmm:

not only do they have sounds, but if you manage to locate the source there will be dolphins.

whales are also simulated as are their sounds, which are much more baritone.
