Our Focus

Illinois-Indiana Sea Grant works to create and maintain a healthy coastal environment and economy in the southern Lake Michigan region through research, education, and outreach. By connecting decision-makers—from resource managers to residents of all ages—with the latest science, we help strengthen and preserve ecosystems and communities.

We are focused on key concerns along the most populated shores in the Great Lakes region, including contaminants, water affordability, flooding, erosion, and more. IISG funds research that informs management decisions, engages communities working to protect their natural resources, and fosters a well-informed public.

Here are a few examples of how IISG makes a difference:

  • Our three buoys in nearshore Lake Michigan waters help inform more accurate weather forecasts, contributing to safer recreation, and they provide years of data for scientists as they seek to understand lake conditions over time.
  • IISG’s Be A Hero messaging that informs boaters, fishers, and others about how they can help prevent the spread of aquatic invasive species in the Great Lakes and inland waters has high brand recognition in Illinois.
  • With the U.S. seafood trade deficit at over $20 billion per year, IISG is making it easier for consumers to find local aquaculture producers. Plus, we are providing training to help farmers process their fish, opening new market opportunities.

IISG works in partnership with many organizations, institutions, and agencies in the region to reach more audiences and multiply opportunities for success. We bring together scientists, educators, policy makers, community decision makers, outreach specialists, business leaders, and the public to work towards resilient communities and healthy waters.

The Sea Grant program is a partnership of National Oceanic and Atmospheric Administration (NOAA) and state universities, with IISG located at Purdue University and the University of Illinois Urbana-Champaign.
