Is there a doctor in the house? Yes, in fact Lake Superior has been undergoing a health check. This week The Sea Grant Files welcomes Dr. Michael Sierszen, Research Ecologist with the United States EPA's Mid-Continent Ecology Division talks about the past month of research. Dr. Sierszen spent a large part of September aboard the EPA’s research vessel "Lake Guardian." To get the story behind the research we invited him to the studio so we can ask… “What on Earth were you doing out there?”
