SoundHAB: Possible Harmful Bloom in Totten Inlet

[Krembs, Christopher (ECY)]

Additional spatial context.

 

The marine monitoring unit at Ecology took aerial photos over Totten
Inlet on Sept 13, 2010 (attachment, DSC 0138) and found that the bloom
extended into Budd Inlet (attachment, DSC 0140). The extent of the bloom
was significant in both Inlets. Budd Inlet had also jellyfish in
abundance, (yellow-white dots on DSC 0140 are mass accumulations of
Aurelia sp. 10-40 meters in size).

Thanks for the information.  

 

Pacific Shellfish Institute has been collecting weekly phytoplankton
samples from Totten Inlet from May to early September of this year.  We
began seeing Akashiwo at low concentrations (40,000 cells/L) on 7/7 and
cell counts increased to 460,000 cells/L by 7/21.  They remained at or
near this concentration until peaking on 8/18 (684,000 cells/L).
Dissipation seemed to occur around 9/8 (175,000 cells/L) when we
collected our final sample for the season.  It appears something
triggered the initiation of another bloom....a sizeable one at that.  

 

In 2002-2003, we collected weekly plankton samples in Totten Inlet for a
mussel raft project.  Maximum Akashiwo counts for those 2 years were
268,000 cells/L (8/26/02) and 586,000 cells/L (8/7/03).  

 

Hope this information is helpful.

The dense bloom of marine algae in recent samples from Totten Inlet is
Akashiwo sanguinea. This dinoflagellate was responsible for bird deaths
on the outer Washington coast in late summer/fall 2009 due to the
production of a surfactant like compound. Bird deaths were also
attributed to A. sanguinea in Monterey Bay in 2007. 

A cell count of the whole water sample was 660,000 cells/L.

Gordon King of Taylor Shellfish reports a very dense bloom of some kind
of marine algae in portions of Totten Inlet presently.   If any SoundHAB
recipients are in the area and can sample, please take live or formalin
preserved samples so we can identify the potential culprit.  

 

Also, several of you have asked about the HAB publication that I just
produced with Tim Tynan and Nicky Haigh about Heterosigma affecting wild
fish and salmon, so I attach it here for your use.  This is pertinent to
Totten Inlet as the Kennedy Creek Chum would normally be milling in the
area at this time, with mean run timing of mid November.

 

Best regards,
