Central Basin or northern Hood Canal. The toxic samples from Budd Inlet 
near Olympia, for example, contained a lot of Ceratium . It is possible 
that the Ceratiurn "blooms" were enhanced by the abundance of organic 
material in Budd Inlet water, acting to stimulate proliferation of the 
microscopic plant. These organic materials occur in high amounts in some 
south Sound inlets both due to natural sources and man-made discharges.
