Underwater Seismic Guns in the Great Lakes!

 

The University of Notre Dame's biology department is also home for the Great Lakes aquatics species director for the Nature Conservancy, Lindsay Chadderton. 

Chadderton and crew will be using "seismic guns" to clear rusty crayfish and round gobies (photo above) from spawning reefs in the Grand Traverse Bay where they eat fish eggs.  These seismic guns are a little 'over my head' -- so, you'll want to read the South Bend Tribune story.
