Our Focus
These are trying times for the environment. With climate change upon us, as well as a host of other concerns, such as population growth, aquatic invasive species, contaminated waters, and loss of natural habitat, the southern Lake Michigan region faces many challenges. Illinois-Indiana Sea Grant (IISG), with its unique mandate to bring the latest science to those who can best use the information, serves a critical role in empowering people to solve problems in sustainable ways.
One of 34 Sea Grant Programs in the U.S., IISG is focused on the southern Lake Michigan region—104 miles of heavily urbanized and industrialized shoreline in Illinois and Indiana. One third of the population of the Great Lakes lives along the shore of Lake Michigan between Milwaukee, Wisconsin and Michigan City, Indiana.
The program is funded through National Oceanic and Atmospheric Administration (NOAA) via the National Sea Grant College Program, as well as the University of Illinois and Purdue University, but IISG also works in partnerships with key organizations, institutions, and agencies in the region to reach more audiences and multiply opportunities for success. IISG brings together scientists, educators, policy makers, community decision makers, outreach specialists, business leaders, and the general public to work towards a healthy environment and economy.

Our collaboration with @shedd_aquarium was recently featured in a news article by @wttwchicago! The article discusses concerns raised by scientists, including how the St. Paddy’s Day dye in the Chicago River might impact fish and their behavior. It’s a timely conversation about how environmental factors, like dye, can affect our local ecosystems.
Check out the full story to learn more about the ongoing research and its implications for the health of our river and fish at the link in bio.
