English: Freshwater Harmful Algal Bloom - Surface Mats |

Description |
English: a group of people examine a pond with clumps of brownish algae floating on the surface. Cyanobacteria, also known as blue-green algae, often causes algal blooms in freshwater and occasionally in marine environments. There is a variety of algal species, all appearing in the water differently. This example shows a HAB that appears as chunks that could lift out of the water. These aggregated algal cells float to the surface to form clumps or a mat on the surface. |
