I asked two marine biologists about this, and they both think it was low salinity, caused by rain and flooding. Also they mentioned sea cucumbers as being very sensitive to fresh water, and I did not see any of the small White sea cucumbers as I did on my first dive there. But that could be also due to lousy visibility I experienced this time.
The floating dock was purchased in the Spring of 2007 from Bremerton, towed to Port Orchard for short-term storage before being tied to the seawall here at Langley. I was surprised that the docks were not cleaned before being transported, there are chunks of large Vancouver Feather duster worms on it, they also cover all the mooring chains stored now on deck, and they stink up the whole area. The master plan for LAngley Marina doesn't bode well for our diving at Langley Tire Reef.

Interesting that the change of conditions from their former location to Langley was enough that they couldn't survive, when other creatures could. Do you know where the dock was formerly located?

Scallops no more

Revisiting the floating dock in Langley. I did not find one live scallop. All the shells are now clean...I miss their colorful smiles .. :pale:

Scallop demise

Postby Jan K » Thu Dec 13, 2007 10:17 pm

The recent rain storm was not kind to Whidbey underwater visibility. The water is filled with fine silt. I went to check Langley, it looks like Lingcods are staking out territory, no egg masses yet. At the end of the dive I checked the new Langley acquired floating dock and found that all the Spiny Pink Scallops are dead, their shells gaping open, all the inner organs exposed totally. This batch arrived on the dock attached to its concrete sides. We did not have Scallops at Langley before. I asked couple of marine biologists, and they think that it was low salinity due to the river runoff what caused this. Other marine life on the dock, such as Feather-duster worms, Plumose anemones seem to be OK. Did anybody else observe this at other dive locations?

Jan, your artwork is simply amazing!

BTW, thank you for solving my Christmas present issues -- I just ordered nine copies of the book!

Muck

Postby Jan K » Sun Dec 09, 2007 10:25 am

We all been there. Murky water and with limited visibility, the usual array of critters to greet us diminishes, making it difficult to locate them, maybe they scramble out of the area before we see them. One of the the exceptions are nudibranchs, specially the White-lined Dirona, aka Frosted or Alabaster Nudibranch. The dive is saved, twinkle twinkle little slug......

Very cool, as always, Jan. Valerie & I saw our first "mouse" of the season at Redondo last week.

Very cool information, Jan! I'll have to keep my eyes peeled for those mostly-buried crabs.

Dungeness crab

Postby Jan K » Wed Nov 21, 2007 8:37 pm

When our fellow NW Diver Greg Jensen asked for help to identify Dungeness crab incubating areas, I took a much closer look at my backyard here on Whidbey where I saw in the past crabs burying themselves, but thought that they were the soft shells after molting, hiding from predators. Greg description of what is also happening helped me open another chapter of my understanding of the underwater world. Thanks Greg! Please note, that the egg pictures on the third panel are from a two dead crabs I found, not victims of my picture taking. I have no idea what killed them, that is probably another chapter..

OOOOH . . . I spotted one of those on our James Island dive in the San Juans in early October, but nobody got nearly as good a picture of it as you got of this one! They're really beautiful in person, even without the benefit of a macro lens.

Eel Grass Buffet

Postby Jan K » Sat Nov 17, 2007 10:50 pm

In the murky waters of Holmes Harbor I found two slugs in the close proximity, one is the hunter which uses its hood like a fishing throw net to catch small crustacea living on the blades, while the Dendronotus iris, or Giant Nudibranch is more famous for attacking Tube-dwelling Anemones, here on the Eel Grass it is using its teeth on hydroids..

I did not see what the trap was baited with, but it sure attracted plenty of dinner guests..

It was very interesting to watch. Here is another shot, it shows how the star is hesitant to "touch down" the arms facing the sea pens while all the others are in normal, down position. Sorry about the quality of the picture.
