SoundHAB: FW: North Hood Canal bloom update

[Vera Trainer]

Hello Peter
We at NWFSC can do the SEM within the next couple weeks if we can 
receive a sample.  If someone else wants to do it, that's ok, too.  
Perhaps the same group that ID'd the outer coast species should do this 
one?  We'd need assistance from someone (Rita?) in IDing the 
coccolithophorid. Sincerely, Vera Trainer
