Last Saturday (August 25, 2007) Kathryn and I went out with the Sea Divers aboard the Sea Bass.

Our first dive was the wreck of the Palawan off of Redondo Beach. Captain Richard put the anchor right against the side about mid ship. The surface water was a touch green with about 25 foot visibility, but below 80 feet the visibility opened up to over 50 feet. We could easily see across the wreck and to the next compartment. There several lingcod, but none would let me approach them close enough for anything but a fish butt shot.

Our second dive was on the North Hyperion Outfall Pipe off of El Segundo. It is one of the two pipes the pumps out the treated sewage from the Hyperion Treatment Plant 5 to 8 miles offshore. It is rich with life since it is some of the only structure in what is mostly the sand bottom of Santa Monica Bay. The visibility was only about 12 feet, but there was plenty of interesting life. This dive is a live boat dive since it is a no anchor area. The captain drops you just North of the Pipe and you swim south until you hit it. One on the pipe you stay on it until you are ready to surface. The areas with the red buoys are to be avoided since they are the intakes for the SDWP power plant.

Our last dive was on the wreck of the Avalon. Captain Richard was having an exceptionally good anchor day because he dropped the anchor about 10 feet from the bow of the Avalon. There was a huge school of Rhacochilus toxotes (Rubberlip Surfperch) hiding in the bow. Since the visibility was so good I spent much of the dive taking pictures of the perch. The temperature at the Avalon was about 62 °F which is very warm for that area. I think it was the warmest dive I have ever had there.
