SE.SR Ytansamling av alger: VisningstjänstSMHI Algae Surface Accumulation: View Service
This WMS view service, published by the Swedish Meteorological and Hydrological Institute (SMHI), provides maps showing blooms of cyanobacteria (blue-green algae) detected from satellite data around Sweden. Blooms visible at or near the sea surface are shown directly, while blooms that are faint or obscured beneath the surface are classified as a lower-confidence category, such as a risk of surface accumulation. The service supports monitoring of algal bloom extent and severity for coastal and marine water quality assessment.BESKRIVNING Kartorna visar blomning av cyanobakterier detekterade från satellitdata. Blomningen kan detekteras från satellit när den finns på eller nära havsytan. En blomning som är otydlig eller svår att se på grund av att den befinner sig under ytan definieras som "Risk för ytansamling", medan...
