SoundHAB: Heterosigma bloom in Central Puget Sound

[Sackmann, Brandon (ECY)]

Just updating the figure I sent around yesterday to include the most recent MERIS data (27 August) before heading out for the long weekend...

Hi Jim,

Ferry data suggests that the bloom off of Bainbridge Island is still going strong - also, it looks like there might be a good MERIS image available from 27 August, but the full resolution imagery has not yet made it into the archives that we draw from...looking forward to seeing what it looks like!

Here is a follow-up from Erika.  Jim

Here is an image with some analysis by Erika Young for August 23.  Do the locations agree with any of your sampling?  Jim

Heterosigma is blooming in central Puget Sound.  Although the total extent of the bloom is not known, cell counts over the weekend were higher in the backwater areas of Kitsap County and Bainbridge Island (Port Blakely and Brownsville).

However, ambient cell concentrations as high as 1.7 million cells per liter were recorded last night near Bainbridge Island/Clam Bay fish farm areas but mitigation efforts (upwelling of deep water) is apparently effective in reducing cell concentrations to 0.3 million cells per liter in the fish cages.

The bloom was first reported late Friday night, but I didn't receive the information until just now.   With the wind and rain expected today, it may attenuate the intensity of the bloom, although clearing and sun tomorrow (Tuesday) may allow for the bloom to become re-established.   It could go either way based on past experience and the amount of wind mixing and duration/intensity of the low pressure cell moving  through is key in this process.

More information may be available later today.
