Mussel Mapping with GMRI

Show us your mussels! Join Seacoast Science Center, GMRI and several partner organizations for a mussel bed mapping extravaganza event that spans the coast of Maine and New Hampshire! Help us observe where mussels are (and importantly where they aren’t) during an extreme low tide on June 18. While in the field collecting observations, you’ll also be learning about blue mussel beds, local ecosystems, and ongoing research. The data you collect will be put to use in the Mussel Bed Mapping Community Science Project.

Before joining us in person, we encourage you to attend our webinar on Thursday, June 11 at 12 PM to learn about the basics of blue mussels, the community science project your data will be contributing to, and how to participate.

In-person group meet-ups will be happening at multiple sites across Southern Maine and New Hampshire. Or you can participate independently at a different site! When registering, please select where you plan to make observations. Fieldwork will take place in the intertidal zone, so be prepared to walk along mudflats.

Learn more about the project and sign up to participate here. 

Note: Attendees responsible for Park fee.
