Sea Grant staffers take new interactive watershed planning tool for a spin
November 6th, 2013 by Irene Miles
Staff members from six Great Lakes Sea Grant programs met at Purdue University last week to preview a new web-based tool that will help local planners make sustainable land use decisions. The two-day workshop gave Sea Grant specialists a chance to work through the tool’s four-step process and suggest changes before they start using it with planning groups and communities next spring.The Tipping Points and Indicators tool uses watershed data and cutting-edge research to show planners where aquatic ecosystems in their region are stressed by various factors to the degree that they are in danger of crossing a “tipping point,” triggering rapid and sometimes irreversible shifts in their functioning. With help from a Sea Grant facilitator, planners can use the tool’s interactive maps and simulators to specify important regional priorities, pinpoint specific land use practices that threaten ecosystem health, and test how further development, restoration, or conservation projects would help or hurt. Together with suggested policies, ordinances, and outreach efforts, these features help planners develop watershed management plans that prevent ecosystems from being degraded beyond repair.
The tipping points tool is part of a four-year project funded by NOAA and EPA and coordinated by Illinois-Indiana Sea Grant. Research and outreach partners include Purdue University, University of Michigan, Michigan State University, University of Minnesota Duluth, University of Windsor, the Great Lakes Environmental Research Laboratory, the Cooperative Institute for Limnology and Ecosystem Research, the Great Lakes Restoration Initiative, NOAA, and the Sea Grant Great Lakes Network.

In the news: Great Lakes lawmakers consider a ban on harmful pavement sealant
November 14th, 2012 by Irene Miles“Negative effects on fish and other aquatic animals include inhibited reproduction, fin erosion, liver abnormalities, cataracts and death, according to Geological Survey reports.Coal-tar sealcoat makes up about half of the PAHs in lake sediment, according to Environmental Science and Technology. It is why PAH levels have increased in the sediment of urban and suburban lakes since 2000 even when other major PAH producers, like power plants, have been decreasing emissions.”
Local water travels a long, long way
June 25th, 2012 by Irene MilesWatersheds are areas where water comes together and drains to a common place. In addition to the streams and rivers and creeks that we can see, though, watersheds encompass a huge range of pathways for water, and your nearby water supply might be part of a very large system that spans multiple states.
“Of course, obtaining sustainable development in town isn’t enough, in and of itself, to guarantee high quality, fishable and swimmable rivers and streams. Industry plays a part; utilities and waste water treatment plants play a part; sensitive farming, ranching, and/or timbering play a part, all in different proportions depending upon the particular watershed in question.”

Social media can be a great way to market your small business and products, but sometimes it might feel like you are casting a net again and again to find that your net is empty. After all, the point of using social media marketing is to connect with customers. By attending this workshop, you will:
-Hear Research Findings
-Participate in an Interactive Workshop Session
-Learn Real World Application
-Tour a Shrimp Farm
-Network at the “After Hour Social”
This program is supported by the North Central Regional Aquaculture Center and put on in partnership with the Indiana Aquaculture Association Inc, RDM Shrimp, and Ohio Sea Grant, The Ohio State University.

This fall, our team took advantage of several opportunities to showcase our engaging educational programs at outreach events.
One highlight included the Great Plankton Race, where participants built plankton models and tested various adaptations that help this vital part of the food web survive.
Illinois-Indiana Sea Grant has created another resource for students in the Great Lakes region to engage with real-world, professional water quality testing equipment. Currently, the Know Your H₂O Kit is being pilot tested in five classrooms, and for one Ohio teacher, it’s a hit for her and her students.
“The lessons have been incredibly useful,” said Shari Insley, a science teacher in North Olmsted, Ohio. “They not only aligned well with our Ohio 7th-grade science curriculum but also brought concepts to life in a way that deepened students’ understanding. For many students, this was their first time using scientific tools to test real water samples, and it sparked curiosity about local water systems and environmental stewardship.”

This Halloween, we’re diving into the eerie depths of the Great Lakes.
Each lake has its own spooky story:
🕯️ Lake Superior hides ghost ships beneath its icy waves...
🦴 Lake Michigan whispers tales of vanishing beaches…
🌉Lake Huron hides prehistoric hunting camps on a lake bottom ridge...
🧪 Lake Erie bubbles with algal blooms that glow like potions...
🦠 Lake Ontario was first to host strange creatures like the blood sucking sea lamprey.
Never fear, we have resources to help you make these fascinating topics less frightening at iiseagrant.org/education.
