Today I was out on my boat and noticed several "chunks" of blue/green algae floating just below surface of pond. They would break up if touched but were kinda odd. They looked like the stuff flourists used to use to arrange floral displays in vases.

First time I've observed these - saw a number of them in various areas of pond. Anyone know what these are?
