A new environmental sensing buoy will be placed north of Chicago this summer, making it easier than ever for Illinois boaters and beach-goers to spend a fun, safe day on the water. 

Michigan City Buoy


Like its counterpart in Michigan City, IN, the nearshore buoy will relay information on wave height and direction, wind speed, and air and surface water temperatures in near real time. A webcam will also make it possible to watch changing lake conditions first-hand.

 
This is the newest in a string of nearshore buoys along the Lake Michigan shoreline. In addition to allowing people track waves and temperatures, the data they collect will help officials warn beachgoers when contamination levels may make swimming unsafe. Researchers also rely on the real-time information to manage fisheries, monitor lake currents, and improve hazardous weather predictions.

 

The Illinois buoy, jointly operated by IISG and LimnoTech, is expected to go online in May. The project is funded by the Great Lakes Observing System through a grant from NOAA Coastal Storms.
