EMPIRE, MICH. -- Anyone around the world can access real-time information about water conditions at Sleeping Bear Dunes National Lakeshore — and even see video of what’s happening beneath the water’s surface — thanks to a yellow buoy bobbing out in Good Harbor Bay.

As part of a collaborative monitoring and research project, the buoy shares wave height, wind speed and direction, air and water temperatures, humidity, and other data, updated every half hour.
