EOMAP has released a mapping application designed to track harmful algal blooms (HAB) in Lake Erie. ย
Pulling data fromย US and European satellite sensors about turbidity andย chlorophyll, the app tracksย blue algae blooms which are harmful to Lake Erie’s ecosystem, causing aquatic dead zones.
ย In addition, algae blooms are a danger to ย drinking water, aquaculture industries, and the public welfare. NOAA has recently issued warnings aboutย Microcystis cyanobacteria blooms in the lake.
Tracking Algae Conditions Daily
Theย algae bloom monitoring program developed by EOMAP for the Great Lakes region now tracks algae conditions daily. ย
Three different parameters can be viewed on the algae bloom map: turbidity, Chlorophyll-a, andย Harmful Algae Blooms (HAB) indicator. ย
Turbidity which isย the degree to which light is being backscattered by particles in the water. ย This measurement is useful forย monitoring sediment plumes from dredging and dumping activities. ย In addition, trackingย Chlorophyll-a is important for measuringย of phytoplankton. ย
Theย HAB indicator parameter shows possible areas affected by harmful algae blooms formed by cyanobacteria containing phycocyanin.

Aggregated Algae Bloom Data
In addition to daily conditions,ย EOMAPโs eoApp-US also provides spatially and temporally aggregated data: daily means (Dโmean) and moving, weekly means (Mโmean). ย
The app uses anย algorithm developed by EOMAP to detect blue algae containing phycocyanin pigments.
Users can try out the app by visiting EOMAP’s eoApp US page.
