Traverse City, Mich. (AP) -- Federal scientists have developed a system for forecasting the location and intensity of harmful algal blooms on the great lakes.
The National Oceanic and Atmospheric Administration is releasing details about the new system Thursday.
It will focus initially on Lake Erie, where the problem of algal blooms is particularly acute.
But the agency hopes eventually to expand the system's reach across the great lakes.
Harmful algal blooms produce toxins that can endanger human and animal health.
They also can form layers of ugly, smelly scum along beaches, which hurts the tourism economy.
