I've a similar experience to Tim's -- was in the water with Howard4113, and we were puzzling at the noise.
It seriously sounded (to me) like the same noise, say, a whale would make when it breached, but continuous. You know, like when you take your arm and slam it into the water surface and it makes the "ka THUMP" noise?
Thought maybe quake, but didn't hear anything about it until the mid-afternoon at Starbucks.
