Tracking conditions that promote the onset of flourishing HAB events

Recently, I have had questions regarding the recent trends in paralytic shellfish toxin in Puget Sound. 

Turns out, there are local resources for those interested in trends in Harmful Algal Blooms in Puget Sound. One of these efforts is led by state managers, environmental learning centers, tribal harvesters, and commercial fish and shellfish farmers, called SoundToxins.


 They have three goals that are also the goals for my postdoc project:

  1. to determine which environmental conditions promote the onset and flourishing of HAB events or unusual bloom events,
  2. to determine which combination of environmental factors can be used for early warning of these events and
  3. to document unusual bloom events and new species entering the Salish Sea.

I also found a publication from the School of Oceanography and Climate impacts and School of Aquatic and Fishery Sciences at the University of Washington and NOAA. 

Found here: https://www.fs.usda.gov/treesearch/pubs/35297 

Here, temporal and spatial trends in paralytic shellfish toxins in Puget Sound shellfish are documented dating back to 1957.

For the Salish Sea Research Center, there are 3 marine stations that collect data. If, these data include sea surface temperature, sea surface salinity, air temperature, precipitation, streamflow, tidal height difference, upwelling, wind speed, I might be able document paralytic shellfish toxin accumulation along with these environmental factors to track conditions that promote the onset of flourishing HAB events.
