SoundHAB: FW: North Hood Canal bloom update

[Rita Horner]

Hi All,

Carla Stehr at NOAA SEMed the Lugol's sample Renee Rose sent from HCSEG. 
Unfortunately, she didn't find anything she would call a coccolith.  This 
could be because the coccoliths were dissolved in the acid Lugol's or 
there weren't any or very few cells to begin with.  The only thing I can 
think of to try again is to filter all the unpreserved water I still have 
from Dabob Bay and hope that there are some coccoliths still in it.  Carla 
is willing to try again in about 3 weeks.  Is it worthwhile to do this?

Rita
