I dunno - no where near enough experience to figure that out - the currents still have me baffled. I'd think it might effect it somewhat but there's a lot of water moving thru that channel so I wouldn't think it'd be long term. I sometimes think that rain and drainage from the mangroves have more effect than anything.
I had one DM tell me the hurricane that was on the west coast of Panama was jacking with the currents and the viz. I don't know how it would do it, but I wasn't going to argue with someone that probably had 10,000+ dives in those waters.
