We all know buoys are critical for water safety on the Great Lakes, but did you know data is collected from an entire network of technology for scientists to analyze regional trends, natural resource managers to improve their work and policy makers to make informed decisions?

In Episode 10 of Teach Me About the Great Lakes, titled “A Lot of Different Kinds of Data,” Illinois-Indiana Sea Grant’s Stuart Carlton and Hope Charters talk with Kelli Paige, chief executive officer of the Great Lakes Observing System (GLOS), about how GLOS works with Illinois-Indiana Sea Grant and other partners across the Great Lakes to collect and visualize important and useful data. We also discuss how data use has changed as technology has changed and about GLOS’ Smart Great Lakes Initiative.

Teach Me About the Great Lakes is a monthly podcast in which Carlton—a social scientist who grew up in the South near the Gulf of Mexico—asks people to explain the biology, ecology and natural history of the Great Lakes. A new episode will be released on the first Monday of each month. The latest episode is embedded below.
