Hi all,
Does anyone have any information on a bloom last Friday in Pt. Angeles harbor? One of our Spills responders reported a bloom there and our management wanted more information to pass along to reporters, etc.
Any information is appreciated!

The bloom near Anacortes (Fidalgo Bay) was Gonyaulax spinifera and is probably the same as the G. digitale reported from Cypress Island. The two may be difficult to tell apart. G. spinifera formed an extensive bloom in August-September 1990 that extended at least from Grays Harbor to Barkley Sound on the open coast and extended well into the inland waters of BC and Washington. There were reports of shellfish mortalities in Barkely Sound due to oxygen depletion.
The Protoceratium bloom reported for Sequim Bay is P. reticulatum, the only species of this genus present here. It is not uncommon here and often blooms this time of year.
