Thick mats of slimy green algae are spreading over some tidal mudflats in the Portland, Maine area, raising concerns about nutrient levels in the water and the algal bloom’s impact on marine life, according to an article on PressHerald.com.

Green algae now cover part of the muddy bottom of Portland’s Back Cove as well as parts of Mill Cove in South Portland. Friends of Casco Bay, the nonprofit organization that monitors conditions in the bay, is also looking into reports of algae blooms in Freeport, Brunswick and other coastal towns in the area.
