Algal bloom season is here. These tools will help you keep track.
A bloom of harmful cyanobacteria has grown in Lake Erie’s western basin, according to the latest bulletin released today by the National Oceanic and Atmospheric Administration. The bloom is concentrated in Maumee Bay, while a separate and smaller bloom has appeared in Sandusky Bay. As part of our ongoing coverage of toxic algal blooms in the Great Lakes, which shut down a public water supply system for the first time last fall, we are creating a space to bring together a range of available maps and data to track the progression of these blooms.
Do you know of a great data source, or would like to see something included in our Algae Dashboard? Share your ideas on Twitter! @circleofblue You can also share your photos of the algal blooms on Circle of Blue’s Instagram account by using #GLalgae #circleofblue.
Lake Erie Harmful Algal Bloom
The satellite images below show the current bloom intensity and forecasts of how it may evolve in the next few days.
You can see NOAA’s complete bulletin here.
Lake Erie Water Temperature
Information about water temperature, which can influence algal blooms, is available from both the NOAA bulletin and the Great Lakes Observing System — a network that pulls near real-time data from various sources in the Great Lakes Basin.
Lake Erie Chlorophyll Concentration
GLOS also publishes remote sensing images of chlorophyll concentrations. Chlorophyll is found in algae, but not all forms of algae are harmful.
