Giant Pacific Octopus (GPO)
Dan Ritchie, Brian Lund, and Pieter Booth met at the pipeline at 9:30 on this cold, foggy, but calm morning. We entered the water at about 10:00 and started our long swim out to the pipeline. As soon as we could see the rocks we dropped down to the bottom at 12 feet. We swam all the way out to the end going down one side, then back the other. Pieter was the only one who spotted an octo, and that one was well hidden way back in the rocks. Several small middens were seen, but no other octos. Lots of lings on eggs, and tons of kelp crabs eating the eggs (see photos). Also spotted leopard dorids, lots of kelp greenlings, and a few assorted rockfish. Water temp was 46 and viz was a decent 20 feet.

For the record, it's a 0.2 mile swim at high tide, each way...
