National Marine Sanctuary




For more than 40 years our national marine sanctuaries have worked to protect places of historic/cultural, ecological, and natural importance in America’s ocean and the Great Lakes.

We are pleased to be working with communities along our Wisconsin coast to apply for the establishment of a national marine sanctuary to preserve shipwrecks in our mid-Lake Michigan region. Watch for updates on this effort. To learn more about NOAA and National Marine Sanctuaries, visit

This new temporary exhibit showcases artifacts representing science, service and stewardship of the National Oceanic and Atmospheric Administration (NOAA) including themes of history, navigation, weather, and fisheries.

We are also highlighting shipwrecks of the mid-lake region of Lake Michigan. The communities of Port Washington, Sheboygan, Manitowoc, and Two Rivers are working collaboratively toward a designation of a National Marine Sanctuary to protect shipwrecks in these waters, and we are excited to highlight our own treasures beneath the surface just off our coast.

Special programs and events will take place related to this exhibit, which will be on display until April 17, 2016.
