Blue-green algae bloom in Lake Erie • Earth.com

Last update: December 14th, 2019 at 8:00 am

Today’s Image of the Day from NASA Earth Observatory shows a severe algae bloom across the western half of Lake Erie. 

The most prevalent organism driving the bloom, Microcystis cyanobacteria, produces a toxin called microcystin that can cause numbness, dizziness, vomiting, and even liver damage. 

On July 29, the National Oceanic Atmospheric Administration (NOAA) reported unsafe toxin concentrations in the lake and advised for people and their pets to stay away from areas where scum is visible on the water’s surface. 

This image was captured on July 30, 2019 by the Operational Land Imager on Landsat 8.
