Abstract The charts show cyanobacteria blooms detected from satellite data. The bloom can be detected from the satellite when it is on or near the sea surface. A bloom that is unclear or difficult to see because it is below the surface is defined as "Risk of surface accumulation", where as Surface accumulation denotes an area where the bloom has been concentrated to the surface. Areas where clouds obscure the view are shown in gray, and areas where satellite data are missing are indicated by black. NOTE! Charts from 2002 - 2009 have a different designation for the cyanobacteria blooms. See legend in current chart. Since the satellite cannot see the blooms through clouds, there is also a compilation of the last 7 days. This picture shows the number of days of when blooms has been observed during the last 7 days, which can be of great use when an algae bloom has been going on for a while and the area then becomes cloud-covered. Chances are then that the cyanobacteria bloom is below the cloud cover but that it cannot be detected from satellite. DELIVERY Daily charts (png) with associated texts (json), or weekly compilations (png) can be downloaded for one summer a time.
