IISG receives grant funding to expand AIS prevention work

December 6th, 2012 by Irene MilesIISG summer intern awarded for AIS research efforts
December 5th, 2012 by Irene MilesLainey writes, “Over the summer I worked to help increase recreational water user knowledge of AIS through survey research and outreach. I designed and conducted a survey to help investigate the prevalence of AIS-preventative behaviors among boaters and anglers, a key demographic in the effort to prevent AIS spread. By the end of the summer, I had formulated a formal research report and academic poster presentation based on the final survey results. All efforts in the research and poster presentation were collaborated with my internship supervisor and coauthor, Sarah Zack. The final project of the internship was a presentation of my poster “Evaluation Illinois-Indiana Sea Grant Outreach Efforts in the Southern Lake Michigan Watershed” at the 2012 Illinois Water Conference.

Learning about and connecting with IISG online
November 30th, 2012 by Irene MilesIISG teacher workshop offers Great Lakes info and hands-on learning for the classroom
November 28th, 2012 by Irene Miles
Educators from Illinois, Indiana, and Wisconsin attended IISG’s workshop Nov. 9-10 to increase the presence of Great Lakes science in their classrooms and to improve student awareness of issues related to the Lakes.
All of the teachers who attended this year’s workshop were excited to learn about programs like the Alliance for the Great Lakes’ Adopt-a-Beach, as well as the many exciting student stewardship activities offered by the Shedd Aquarium, the Dunes Learning Center, and the Indiana Dunes National Lakeshore botanists. They also enjoyed the hands-on activities, including using the Enviroscape model to learn about point source/non-point source pollution, and learning how to use GLNPO’s Hydrolab water quality monitoring instrument.
In the news: Algae and invasives threatening Erie and other Great Lakes
November 26th, 2012 by Irene Miles“The major threats to all the lakes include invasive species that throw a delicate ecosystem out of balance. In Erie, more so than the other lakes, toxic algae threaten the health of visitors and create “dead zones” where no aquatic species can survive.At least 136 invasive species — plants, fish and mussels — have forever changed the lakes. But it’s the potential 137th invader that officials fear the most. The Asian carp wants nothing more than to spread through the Great Lakes and continue its feeding frenzy. Though a live fish has yet to be found, DNA tests suggest that they might already have infiltrated Lake Erie.”
Early data from Michigan City buoy helps scientists, anglers, and boaters
November 6th, 2012 by Irene MilesThe research buoy launched off the coast of Michigan City, IN earlier this fall has been brought inland for winter, but will return to the water next spring for its first full season monitoring environmental conditions in Lake Michigan’s nearshore waters.
More than 500 people have visited the website since it went live in early September to see real-time snapshots of lake conditions or to examine trends shown over 24-hour and 5-day periods. IISG staff members have heard from sailors, kayakers, anglers, and local residents who say they plan to regularly use the information collected on wave height, water temperatures, and wind speed before venturing from shore. Sailors from Indianapolis told IISG that the up-to-date information on lake conditions will help them more safely make their seasonal trip from St. Joseph, MI to Michigan City. The same data will also be used by fisheries researchers at the Purdue University West Lafayette campus to determine when to make the two-hour drive up to the lake for sampling trips.
The buoy’s launch also attracted regional press coverage that continued well after it was placed in the water. Indiana TV and newspapers were joined by news outlets from Illinois and Michigan—including the Detroit Free Press—in their coverage. The launch was also featured in trade blogs such as the Environmental Monitor and recreational forums like the Great Lakes Angler Forum.
In the news: Water levels still low in Great Lakes
November 2nd, 2012 by Irene MilesLakes Michigan and Huron almost set records for low water levels in October, as the long-term effects of this summer’s drought are still being felt.
From the Detroit Free Press:
“The U.S. Army Corps of Engineers, which tracks Great Lakes ups and downs, recorded Michigan-Huron at 576.6 feet above sea level for October. That’s an inch-and-a-half above the lowest point for that month since the agency began keeping records in 1918, and about 6 inches above the all-time low recorded in March 1964.
Michigan and Huron are considered one lake from a hydrological perspective because they have the same surface level and are connected at their northern ends by the 5-mile-wide Straits of Mackinac.”

In the news: Search resumes next week for signs of Asian carp
October 11th, 2012 by Irene MilesChicago area waters will be searched again beginning next week for indicators of Asian carp presence near Lake Michigan.
From WTAQ.com:
“Over 170 samples were taken from Chicago’s North Shore Channel from June through September – and 10-percent had the carp’s DNA. The same was true for 17 of 57 samples last month in the nearby Chicago River.
As a result, an actual search for the bloated carp will take place next Tuesday through Friday on the North Shore Channel and a six-mile stretch of the Chicago River west of the city.”
