There have been reports of algae blooms on both the east and west sides of the bay over the last couple of days.  I have one in front of my house as I write this.

water sample 4I grabbed the required 500 ml sample (about 2 cups) in a spent water bottle, skimming it off the surface with a gloved hand.

I then placed a drop on a microscope slide and viewed it at 20X magnification using SOS’s new microscope.  It is B/G algae and to my untrained eye it appears to be Anabaena, a simple multicellular photosynthetic cyanobacterium.  I have no means to determine if it is toxic or not.


Bring your water sample to the SOS Expo and ask the expert, Dr. Greg Boyer.
