    Blue Green Algae (Cyanobacteria) Season Summary. The season summary status of Blue-green Algae shown on the map reflects conditions from early June thru mid October. Observations and samples were collected once each week. Each dot on the map represents a testing site. Blue-green algae can be found in water bodies worldwide, including those throughout Washington State. Blue-green algae contain photosynthetic pigments similar to those found in algae and plants. They may appear as single cells or groups of cells. Colonies may clump together on the water's surface to form a surface scum, which can cause water.

      A recent study of harmful algal blooms in the Chesapeake Bay and its tributaries by the University of Maryland Center for Environmental Science show a . Meanwhile, beachgoers and marine life continue to suffer impacts from a persistent red tide algae bloom that has been plaguing Southwest Florida’s Gulf Coast since this past fall.

The blue-green algae represent a unique stage in the evolution of plant life. The cyanophyta are clearly procaryotic organisms and so they might well be called blue-green bacteria.

However they are the only procaryotes able to produce oxygen from water so their photosynthetic activity is like that of the higher plants (Krogmann, ).Cited by: Lakes Presenting Risk for Exposure to Harmful Algal Toxins (Photo on left) Massive Algal Bloom in the St. Johns River, Florida.

Blue-green Algae Information ulletin Surface water affected by blue-green algae often is so strongly colored. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems, and is often recognized by the discoloration in the water from their pigments.

The term algae encompasses many types of aquatic photosynthetic organisms, both macroscopic, multicellular organisms like seaweed and microscopic, unicellular organisms like cyanobacteria.

A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.
