Buoy temperature chain dances to the data

January 27th, 2017 by

Our Michigan City buoy has a lot of sensors on it, but none are quite so popular as the temperature chain.

Every 10 minutes, 17 loggers, all at different depths, record and transmit the average water temperature of the lake.

Using data collected in 2016, Purdue University School of Civil Engineering student David Cannon visualized what happened in the top 45 feet of Lake Michigan, 3.5 miles northwest of Michigan City, Indiana.

The results shows just how variable the nearshore water is: one day it can be warm all the way to the bottom, and a week later it can be very cold way up at the surface.

For more information on buoys, winds, waves, and how they affect water temperature in nearshore Lake Michigan, see Lake Michigan By the Numbers.

The World Series of Buoy Data: An island of activity amidst a lake of statistics

October 28th, 2016 by

The Chicago Cubs versus the Cleveland Guardians isn’t the only Great Lakes World Series happening this October!

Illinois-Indiana Sea Grant’s Wilmette buoy (45174) has been pitted against the City of Cleveland’s Cleveland Crib buoy (45176) in the World Series of Buoy Data. The match-up is playing out on Twitter. It’s a best of seven series and will last up to seven days. Questions are posted in the morning and answers are posted in the afternoon. After three days of competition, Wilmette is in the lead 2-1, winning both the highest wave and strongest wind gust recorded between July 1 and October 24 of this year. Cleveland saw the warmest water temperature.

See the rest of the series play out on Twitter by following @TwoYellowBuoys, and let us know who you’re rooting for in this best of seven series!

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.

Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.

Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.
