New platforms are being added to Seagull each week, thanks to generous observers invested in collecting and sharing Great Lakes data: free, easily accessible, and open to all.

Here are some of the most recently added platforms for you to check out.

Note: Although these stations are connected, not all are actively transmitting data yet and will be marked “Unavailable” on Seagull.
