SE.SR surface collection of algae: Download service

DESCRIPTION The maps show the flowering of cyanobacteria detected from satellite data. Flowering can be detected from satellite when it is located on or near the sea surface. A flowering which is unclear or difficult to see because it is below the surface is defined as ‘Risk to surface collection’, whereas a ‘surface collection’ defines the areas where flowering has been concentrated on the surface. Areas where clouds obscure visibility are displayed in grey colour, and areas where satellite data is missing are denoted by black. PLEASE NOTE! Maps from 2002-2009 have a different designation for the algal blooms. See legend in the current map. As 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 flowering has been observed during the last 7 days, which can be of great use when an algal bloom has lasted for some time and the area then becomes cloudy. The chances are then that the algae bloom is under the cloud cover but that it cannot be detected from satellite.
