  • Pyrosome
    We had a few pyrosomes come ashore on the last series of King Tides but they looked like they had been dead a while before washing in. Today I saw two fresh ones.

What a wonderful morning on the beach.  Most significant find was the hitchhiking amphipods (Hyperia medusarium), all by their lonesome, on the beach. It was made even more interesting due to the...

250 people on the beach, due to Volleyball Weekend. Numerous gulls observed (82 Western, one Bonaparte's) and two beached birds. Gooseberries are abundant.
  • Among the 500 or so people on this mile of beach, you can still find areas of peace.
  • It's hard to tell from this photograph, but hundreds of temporary volleyball courts have been erected for this weekends tournament. At least 250 people are already playing on them.

  • Fishing for surf perch, this was the only harvesting activity on the beach today.
  • Lot of gooseberries today.
  • Sea gooseberries grace the shore all along this mile.
  • Hard to tell if these amphipods are dead or are just molts.
  • Hard to tell if these are dead or just molts.
  • A trapdoor spider!  This is actually the second time I have found a trapdoor spider along this mile.  I do not know if it was still alive.  Though I took its picture, I wasn't willing to touch or poke it.

  • The drift line was composed of mainly tubeworm casings.
  • An abandoned castle...

It was a beautiful morning. Lots of people were already out and about enjoying the beach. There was a small diatom bloom in the first quarter mile along with a small concentration of water jellies...
  • It was a beautiful day, most of the people were higher up on the beach and not depicted in this photograph.
  • One of five gulls foraging along the tide line.
  • There were not very many of these guys left by the high tide today.
  • There was a small concentration of water jellies in one small section of this mile.
  • One lonely sea nettle.
  • This photograph does not show it well, but there was a small diatom bloom in the same section where all the water jellies had washed in.
  • One of many sails left over from the recent mass stranding of Velella velella.  The sail was covered in diatoms.
  • This is a juvenile harbor porpoise. It was a male approximately four feet in length.
  • Though the porpoise had not been on the beach very long, a gathering of Black-and-White Sea Fleas (Chromopleustes oculatus)had already begun feeding aggressively on its skin.

It was a little windy and rainy today on mile 323. Only three other people were on this stretch of beach, all walking their dogs. The high tide line to the south was littered with surf grass and sea...
  • Looking north from the middle of mile 323.

  • The high tide line to the south of mile 323 had quite a bit of surf grass and some sea palm.
  • One, slightly old, bull kelp.

There was a large debris field which expanded two blocks in the middle of this mile. The debris field contained a plethora of opalescent squid eggs, crab shells bothe dungeness and red rock, sea...
  • Taken from the middle of mile 323 looking south.
  • Close up of the debris.

Calm day on the beach. Tide was high and about 20 people were walking along the beach. One couple was picking up trash, which may be why I saw so little non-organic debris (two plastic bags and a...

  • The large surf which we had been experiencing the last few days brought in Sea Angels most of which were still alive.
  • This is what this stretch of the beach looked like on 1/13/2014
  • This small bird was too torn apart for me to be able to identify.
  • A wave brought this little guy almost right to me feet.  It does not look like the peanut worms I have seen in this area before.  This one is light pink/peach and almost see-through.
  • I am not very good with identifying birds yet, but I am pretty sure this was a fulmar.
  • Here is what the drift line looked like.  The tide was one its way out.
  • The run back was pretty intense because of the large surf.  The sanderlings were feeding aggressively following the waves in and out.
