Scuba Diving Alki Beach Cove 2 12/11/2010

Eric and I escaped to Alki to test out my new Eye of Mine housing for the GoPro HD Helmet Camera. Overall it worked, but the deep dark Puget Sound and the little light sensor only works so well at 105' and 10' of horizontal visibility. Overall without any video lighting I think the setup will work for sharing my adventures with my family and friends.

Northwest Dive Club Gathering Cove 2 Alki Beach 3/28/2010

The NWDC had a small BBQ and dive trip at Cove 2 of Alki Beach in Seattle, WA. Met some really great people and dove with a couple different people, Sonia, Kyle and Roger as well. Sonia got some really great pictures of several Giant Pacific Octopus and there was a considerable amount of life. The first dive we dove down the NDZ buoy line to the logs around 93 feet and saw a lot of really interesting things to include the awesome picture that Sonia got of the GPO with it's eggs. Sonia and I turned around and slowly worked back up the line to the beach. The second dive we dropped down at the little white and red pop can buoy and worked our way down to the I-beams following the guy with the rebreather (I didn't catch his name). We then worked across the log piles at approximately a 300 degree heading and when we reached the NDZ buoy line we worked our way to the beach. The group than stopped for a deco stop, I guess the Uemis computers gathered some deco time while we were down below. With my Cochran I never hit deco, so I was wondering why we were still there after a 5 minute safety stop... Then I was caught off guard by getting regs handed off to me cause I was down to 400 to 450 psi, but I was at a loss of why we were still there... Took the air from Kyle, than from the rebreather guy who had a 40% slung AL80 cause we were still sitting there. Come to find out their computers put them into 10 minutes of deco time. The first dive they went about 10 feet deeper and were there for a little while longer so they had more N2 tissue loading, so that does come into play on the Deco time. The second factor is the Cochran doesn't average tissue loading in it's algorithm, it calculates everything as exact as possible, part of the reason my first computer was a Cochran Commander, and the replacement was Cochran EMC-16.

I finally got my PC software working for the dive computer that allows me to modify stuff in the computer and access dive events and the profiles. So even if there isn't any pictures I'll have something to post. These graphs are depth vs time (blue line) and Temperature vs depth and time (green line).
