Low Tide at the Parker Group

Overcast to mostly cloudy. Temperatures in the upper 50s to low 60s. A bit of light rain in the afternoon. Calm winds.

I was up on the early side to get out for low tide. Predicted to be -2.6ft, with a bit of atmospheric assist it ended up at -3ft.

Paul had gotten in touch last night, and we arranged to get out on his boat. We took his cruiser out to the Parker Group to check it out.

The Parker Group is a cluster of small rocky islands north of Western Channel. I’ve never been to them before.

One of multiple large, dense patches of Dead Man’s Fingers (Codium fragile) observed on the Parker Group near Sitka, Alaska

From the boat I noticed large dark (but not brown) patches on the shoreline. I didn’t remember seeing anything quite like that and wondered if it might be Codium. For some reason it was very abundant on parts of the shoreline facing away from the sound.

We didn’t arrive on shore until only about 15 minutes before the low, but spent most of 90 minutes poking around.

Butterfly King Crab (<em>Cryptolithodes typicus</em>)

Among the critters we turned up was a the other umbrella crab Cryptolithodes typicus which is the much less common one here. It’s only the third time I’ve seen one.

Mystery Tunicate
Though it looks quite striking to me, and I don’t remember seeing anything like it, I am uncertain what species of tunicate this is.

Other highlights included at least one seaweed (kelp) I had not yet made an observation of, an interesting looking tunicate, and an isopod or two that may be new for me (both found by Paul).

We had started on the inside part of the island, then crossed over to the outside. There was plenty more to look at, had we had more time, but the tide doesn’t wait.

Scurvygrass (<em>Cochlearia groenlandica</em>)

Before going back to the boat, we did some observations on the small upland partof the island.

White Adder's-Mouth (<em>Malaxis monophyllos</em>)

Among other things it was nice to see Malaxis monophyllos (an orchid I don’t often see, though it’s reasonably common on these sorts of small islands), and the tallest twisted stalk I ever remember noticing.

Back on the boat, Paul pulled the anchor.

<em>Neoagarum fimbriatum</em>
Neoagarum fimbriatum pulled up with anchor near the Parker Group near Sitka, Alaska

Paul had asked me about species I didn’t have when we were heading out, and the only thing I thought of was Agarum clathrum. Coincidentally, a big blade of it came up on the anchor. [Update: it turned out to be a similar species which was also new for Neoagarum fimbriatum]

Marbled Murrelet

Paul did some fishing around the island while I was on a call and watching the birds, including Marbled Murrelets, a couple of Common Murres, and Pigeon Guillemots.

On the island there had been flocks of Surfbirds and Black Turnstones, but they flew off before I could get a picture. A handful of Black Oystercatchers was quite vocal, and I also heard one Wandering Tattler.

Dusky Rockfish (<em>Sebastes ciliatus</em>)

Among the fish Paul caught were a possible Dusky Rockfish and a small Pacific Cod, both of which are new species for me.

Western Gull

In the channel there were good numbers of gulls. Paul made a loop around the flock as a short side trip before heading to the fuel dock. Among them were at least two Western-type gulls. Also a dark looking gull that might be a Herring Gull.

I had intended to work on collections today, but was tired and didn’t end up doing so, but I did get most of the morning’s pictures processed and observations uploaded to iNaturalist.

Oval Sedge (<em>Carex leporina</em>)

This afternoon I did get out to the golf course with Kitty to revisit a sedge that had previously caused some confusion. Kitty collected some and worked on it to come up with what seems like a better identification.

I noticed this evening that I was up to 2498 species for Sitka after the three new species from this morning’s outing. It’s likely that within the week I’ll be over 2500, either from someone putting names on organisms I observed today that are probably new for me, or from me putting names on liverworts I’m working on.
