{ "currentVersion": 10.91, "id": 14, "name": "Cyanobacteria: Presence of Blooms", "type": "Feature Layer", "description": "This data was derived as part of the Overall Assessment of the State of Nearshore Waters. Cyanobacteria, a blue-green algae, occurs naturally in freshwater but an overgrowth can result in a harmful algae bloom that can release toxins dangerous to human and ecosystem health. Cyanobacteria is assessed by calculating the extent of cyanobacteria blooms detected within a Regional Unit, using satellite composites. An additional flag is assigned to Regional Units where cyanobacteria is a source of high stress, as it is considered a serious concern. Thresholds for severity are based on World Health Organization guidelines.Satellite composites are from the National Oceanic & Atmospheric Association (NOAA) Harmful Algal Bloom Monitoring program.LAKE ERIE: 10-day composite images from the MODIS satellite, with Cyanobacteria Index algorithm applied; June - October, 2012-2017LAKE ONTARIO: 10-day composite images from the MODIS
