Here is the note from Nicky Haigh from Last years bloom off Vancouver IS and
those who worked it up in BC..

Subject: SoundHAB: Coccolithophorid bloom in June, Vancouver I,for ref
to Hood Canal bloom
We did manage to get a sample of the coccolithophorid bloom off
Vancouver Island that happened in late June, (from my concerned fish
farmers in Nootka Sound), and sent it to IOS to get ID'ed, but I haven't
heard back about that. We could see if it was the same species if you
get an ID from the Hood Canal species. The bloom stretched almost the
entire length of Vancouver Island down to the Washington coast - I'm
attaching the image from the NASA "image of the day" website for anyone
who hasn't seen it. I'm also attaching a composite of a few cells that
I took pics of from the bloom sample. Cells appear to be about the same
size as the ones in Ralph's photo (sorry no scale bar!) - my
measurements of cells ranged from ~6.5 - 7.5 um.

At Jan's recommendation, I rechecked the website using % instead of the
name to get the E. huxleyi v. corona pictures. I actually know the Jordan
who was one of the describers of the variety!
No one responded to my message that I had 6 liters of unpreserved sample
if anyone wanted it. However, Renee Rose has a small sample preserved in
Lugol's iodine that she is willing to donate if anyone wants to do the
SEM. One caution here is that Lugol's is usually acidic and is not
recommended for preservation of coccolithophorids.
Vera, if your group still wants to SEM it, I will have Renee send the
sample to you. Let me know.
