Puget sound phytoplankton counts – May 2012

Jack Rensel reports that diatoms are dominant in North/Central Puget Sound today, including Chaetoceros (Hyalochaete spp.), Thalassiosira,  Nitzchia spp. Near Port Angeles Randy Hodgin reports relatively clear water with naturally low dissolved oxygen, following a Thalassiosira bloom a few days ago when dissolved oxygen was supersaturated.

THe MODIS satellite image provided by Brandon Sackmann (Ecology) below shows relatively low chlorophyll concentrations overall, save an increase associated with the Fraser River plume (that could be turbidity related too) that was pointing due south at the time of the image recording.
