A couple weekends ago, Cody Sheik was at a friend’s wedding on Duluth’s Park Point, sipping champagne down on the Lake Superior beach, when he spotted something unusual in the normally crystal clear water.
“It was definitely a bloom,” he recalled. “It’s indescribable. Chalk-green, when it should be nice and clear.”
Sheik would know. He’s a microbiologist at the University of Minnesota Duluth’s Large Lakes Observatory who studies blue-green algae blooms. He snapped some pictures, but he didn’t have anything to take a sample.
Luckily, there are a lot of scientists who study lakes in Duluth. That same night, a mile down Park Point, Holly Wellard Kelly, an aquatic ecologist at UMD’s Natural Resources Research Institute, spotted the bloom while swimming in the lake.
