Cove 2 go boom?

[Penopolypants]

Sergeant Pepper and I were diving Cove 2 early this morning and heard a few loud, sharp explosion-type sounds. They weren't successive and seemed random. I have heard them once before although I can't quite remember what time of day I heard them the first time.

Has anybody else heard them and/or have a clue as to what they are? I kept looking around to see whose tank had exploded.

[John Rawlings]

That was probably Nailer doing Boom drills.

[DiverDown]

I hered them also a few weeks ago. I thought mabey some kinda O-ring failure. 40 minute dive I hered that noise about 6 times..

I've heard this, too- a couple of times, on a recent dive. I had a theory it was the floating platform by the water taxi slapping the water in just the right way when a wake hit it, or something, but I didn't walk down and check it out. It was really loud, and I immediately reached back for my valves, thinking a burst disk had blown......

[Sergeant Pepper]

I thought maybe someone was dynamite fishing. To me it sounded like a small explosion, or something large and not very hyrdodynamic being dropped into the water from a decent height.

Pile driving? This time of year is an "in water" construction season.

[Penopolypants]

I don't think it's pile driving...that has a rhythm, this was random and spaced far apart. It could be some other construction related noise, though.

[Aquanautchuck]

Well the drydocks are real close. It could of had to do with something there.

[Sergeant Pepper]

The dry docks were the other thing that I thought about. Maybe loading containers onto a ship?

[Fishstiq]

Naah... I work around those containers some, and any loader/forklift operator/crane operator clumsy enough to make that kind of a boom loading containers would not be employed long.

Remember sound can really travel a long distance underwater. It could have been something all the way across the harbor.
I was diving there once with Zen Diver and Bob Lew. I kept hearing these horrible pounding, clanging noises. It made my whole body pound. They started when we were pretty deep. I looked over at Valerie who wasn't reacting at all, Bob's deaf so he of course wasn't reacting. I thought, I'm really narced! But the noises kept up until we were pretty shallow so I figured it was some sort of construction going on somewhere. Nothing to be seen anywhere around Cove 2 so I thought it may have come from over in Seattle somewhere. Valerie heard them too and was going through the same thing I was. I guess we just kept looking at each other when the other one wasn't looking.
