Bloom Description

Volunteer reports: The HAB seemed to be spread all along west shore in my area. Sunny, calm water with gentle north breeze, air temp mid 70s F. I noticed earlier in the afternoon that a bloom seemed to be forming, and when I checked back later it was indeed evident with direct sunlight; however, bloom is "light", that is not clearly concentrated but only consisting of light streaks of cyanobacteria on the surface.
