Illinois-Indiana Sea Grant Buoy
This buoy is located three miles offshore of Michigan City, Indiana. The buoy, jointly owned and operated by Illinois-Indiana Sea Grant and the Purdue University Department of Civil Engineering, will advance the understanding of near-shore waters, alert the public to hazardous conditions, protect water quality and improve weather forecasts. From about April 1 to Nov. 1 each year, the TIDAS 900 buoy will relay real-time information on wind speed, air and water temperature, wave height and direction, and other environmental characteristics.
