Volunteers Going Deep! Documenting the Changing Ecology of Lake Michigan

In the summer of 2006, thousands of water birds like seagulls and loons were killed by botulism toxins along the shores of Sleeping Bear Dunes National Lakeshore Park. Avian botulism poisoning had not been a problem in the area since the 1960’s. But ecological conditions in Lake Michigan are changing dramatically due to the invasion of zebra and quagga mussels as well as round gobies.

Over the past 10 years, the Park has become an epicenter for recurring avian botulism. Scientists and resource managers for the National Park Service, the University of Wisconsin Milwaukee, and several other organizations have been studying the changes taking place in Lake Michigan, trying to tease out the specific causes and the options for controlling avian botulism.

However, there are big challenges to collecting data and maintaining monitoring equipment on the bottom of Lake Michigan. The amount of time and effort needed can seem overwhelming. Thankfully, there are citizen scientists who volunteer their time and skills to help these complex research projects move forward.

In this story, we introduce you to Citizen Scientists who volunteer for the National Park Service and just happen to be scuba divers with a real passion for the Great Lakes. Over the past two summers, a small team of volunteer divers have been working with the researchers, collecting samples, cleaning equipment and counting gobies in the nearshore areas off the coast of the National Park.

We met with a few of these volunteer scuba divers at the Scuba North Dive Shop in Traverse City to learn a bit more about what they do and why.

Carol Linteau, Tom Morrow and Ken Holzman were on hand to offer their thoughts on the value and meaning of their volunteer contributions to the National Park Service. A project manager for Sleeping Bear Dunes Lakeshore Park, Dan Ray also provides a little context for the citizens science effort.

  1. WOW !!!
    While I am completely afraid of scuba diving myself, I am proud that my sister Carol, and my son Ryan share the same passion!
    Many of us do what we can to preserve/conserve our world ABOVE the ocean, (I hope).
    I am so proud to have two divers in my family that go “above and BELOW” to make such valuable impact!
