Event Description

How do you take the temperature of Lake Superior?

Lake Superior is a very big and very deep lake. These factors make collecting data such as temperature and water quality difficult. But the The University of Minnesota’s Large Lakes Observatory and the EPA have a solution – gliders.

Join EPA researcher, Tom Hollenhorst as he takes you on a journey through the waters of Lake Superior. Tom will talk about the gliders – autonomous underwater vehicles, which collect data by diving down into the water column and back to the surface as they travel through the lake to sets of programmed GPS coordinates. While underway, the gliders are continuously measuring things like water temperature, backscatter (a metric for the amount of particles in the water), chlorophyll, and CDOM (colored dissolved organic matter).

Suggested donation – $5 per person, $10 per family. Pay at door.
