For folks who ask "why log dives" well, you don't need to log the whole dive but things of note (such as more or less of what you are used to seeing) can be helpful when looked at over time and in the 'big picture'.

keep asking questions, keep reporting!


I'm sad to report that the biodiversity downturn is huge all the way thru the San Juan Islands, Neah Bay, and the Port Hardy area as well, based on recent sightings. Reefs that used to be covered with gobs of colorful life, are now acorn barnacle wastelands. Only the super-high current areas seem to be spared. Even on Browning Wall, the current tuck-ins are now white with acorn barnacles. :( Even medium current areas like Lacan channel are bad. The super high current-swept areas are still looking good though....

I have noticed an increase in red rock crabs, as they seem to be one of the few creatures who munch on the barnacles...

There was a couple on Rockaway (Bainbridge Island) earlier this week. Haven't really seen many others though.

Last October on a dive at Rosario I recorded Dirona as "abundant" on my REEF form (100+ seen)

Wow good to know!! Maybe they'll come back next year?! I saw a bunch of the little Flabellina triophinas at Sund Rock last weekend, pretty cool little guys.

Only occasional in Puget Sound, not like in year's past where you could literally get sick of seeing them.

I saw two large gorgeous white lined dirona in their brownish red phase at Norrander's Reef last week. They were so gorgeous I mistook them at first for Golden Dirona.

In fact, nudibranch populations seem to my eye to be down the last few years in Puget Sound.

I hope I'm wrong, or that it's just cyclical.

Finally saw quite a few Flabellina triophina at Octopus Hole last week, the first ones I've seen in Hood Canal in awhile.

Here's hoping to see more!! :partyman:

I remember seeing a small one at Sund rock on Sunday. North wall, about 30fsw.

I just realized that I haven't seen any white lined dironas around this year. Last year around this time I feel like I saw a lot of them! Has anyone been seeing them?? I love those little critters. :popcorn:
