Sinkhole Science: Groundwater in the Great Lakes
Channel: NOAA Great Lakes Environmental Research Laboratory

When most people think of sinkholes, a massive cavity in the ground opening up and swallowing a car is what usually comes to mind. But when scientists at the NOAA Great Lakes Environmental Research Laboratory (GLERL) hear “sinkholes,” their minds jump to an unusual place — the bottom of a Great Lake.

In this video, NOAA GLERL Observing Systems and Advanced Technology branch chief, Steve Ruberg, explains NOAA's work in understanding why these sinkholes are here, and how they impact the waters of the Great Lakes.
