DULUTH, MN-- The Environmental Protection Agency's largest research vessel spent Monday docked in the Duluth Superior Harbor.

The Lake Guardian is in Duluth as scientists search for new species, evaluating the lower food web meaning algae, and other organisms living at the bottom of the lake.

Scientists are also evaluating the water quality within the lake.

The EPA is surveying all five of the Great Lakes.

Monday was the last day of surveying before the group heads back to Milwaukee to finalize their reports.

"We look at everything like how changing nutrient levels are affecting the lake, to invasive species impacts, to how climate change might change the lake in the future," said Annie Scofield, Chief Scientist on the Lake Guardian.

The EPA says they will be back in Duluth in August when they start their annual summer survey.

Scientists applaud the Great Lakes Restoration Initiative in making the research possible.
