The singing whale is a VERY loud event, on good sonars hearable form THOUSANDS miles :-). We have data about how loud a whale sings, it almost could kill a man if it was close to it :-). But of course at first whale sing is probably not a very broadband event (although I feel it would show up on BB), and more importantly - whales don't sing all the time :-P
So the sound of whales should rather reflect their normal activity, which is much quieter I believe :-). Shrimp is quite noisy thing too (I don't remember if we had data on that), even single animal can be heard on sonar quite far, but again maybe not that loud. We'll take a look at this. Submariner's and sonarman's opinion is welcomed how far could a shrimp be heard on sphere (BB) sonar ? |
