SoundHAB: Discovery Bay Heterosigma

[Megan Black]

Discovery Bay, on the north Olympic Peninsula had an impressive  
Heterosigma bloom occuring over the 4th of July and beyond.  Some  
cells (~1000/ml) were seen in shore samples taken from shore on the  
north side of Diamond Point, but the highest visible abundance was in  
the water mass down in Discovery Bay near Beckett Point.  This  
situation highlights the usefulness of arial observations with bloom  
work. I was sampling at the wrong water mass one mile away simply  
because I had not been up in the airplane - I traveled by car this  
weekend, and did not get up in the air to see around the corner until  
Tuesday evening as we were leaving the peninsula.  Needless to say, I  
was disappointed to be leaving.

discontinuity in the water masses.  Many thanks to Carl Peecher, for  
providing excellent arial work, and the charged camera phone.

Figure 3: Looking Southwest, south of Garner on Discovery Bay.  Wind  
has been blowing down the bay from the northwest and has pushed the  
bloom's surface waters in streaks towards the point.
