SoundHAB: FW: North Hood Canal bloom update

[Jan Newton]

Hi Rita,
I would vote to say that I do think it is worthwhile to do it (note of 
course, I'm not doing the labor!)
I think the acidity of Lugols is very likely the culprit in Renee's sample.
I think that your sample likely would have coccoliths in there still and 
since this is the sample from which you saw the cells to begin with, I'd 
bet you'd have a high probability of getting them again.

I think it is worth the effort because it would give us some valuable 
information to know if these were the corona type or not.
 
my 2 cents,
Jan
