SoundHAB: FW: North Hood Canal bloom update

[Jan Newton]

Hi All,
Interesting information, but I'm not sure that we can respond any 
more...unless there are suitably preserved samples.

The observation and my web-post came during late July-early August. 
http://www.hoodcanal.washington.edu/observations/bloom_fishkill.jsp
Rita did the ID of the coccolithophorid that we posted.  I don't know if 
the samples are still available or suitable for SEM.

I don't know of any current sightings of bloom still...

best,
Jan
