Fifteen educators took to the water yesterday for the annual Shipboard and Shoreline Science Workshop. Scheduled for this week (July 7-13), the workshop offers teachers an opportunity to sail aboard the Lake Guardian on Lake Ontario, conducting a variety of experiments and research processes. This hands-on experience, combined with collaborative meetings with their fellow teachers, will allow each participant to take new information and approaches back to their classrooms.
Among the fifteen participants on the cruise are teachers from Illinois, and two of them wrote in to tell us about what they hope to gain from this week’s experience on Lake Ontario.
Alex Valencic, a fourth-grade teacher at Wiley Elementary school in Urbana, Illinois, looks to bring more information about the interactions between plants, animals, weather, and people to his students and his curricula.
“I’ve taught professionally for five years, first as a substitute teacher and then in my current position for the past two years. My teaching experience involves all of the core subjects, including mathematics, science, literacy, and social studies.
I first learned about the Lake Guardian workshop through a friend who works with the Illinois-Indiana Sea Grant. Some of the major topics of study for fourth graders in Illinois include learning about ecosystems, particularly how plants and animals interact with their environments, weather and global climate, and inquiry-based research. It is my hope that I’ll gain some ‘real-world’ experience studying these issues on Lake Ontario. I would like to integrate the topics into my science curriculum and challenge students to use the information about Lake Ontario to guide their study of Lake Michigan (the Great Lake that borders Illinois). While my students will not be able to go to the Great Lakes to experience the hands-on learning themselves, they will be able to use the resources gained during this workshop in their inquiry projects.”
Jen Slivka, working in the Shedd Aquarium’s learning department, is looking forward to incorporating even more science-based information and research into the exhibits at the aquarium.
“As a learning specialist, I have had the opportunity to coach teachers on inquiry-based science, create professional development sessions, and work closely with teachers on creating stewardship and citizen science programs. I feel very lucky to work with students and teachers of varying backgrounds and pass along my passion for science and education!
Prior to joining the Shedd team, I taught first grade for five years in Plano, IL. My passion for science was ignited when I attended Aurora University to earn my Masters in Teacher Leadership and Elementary Math and Science. My experiences in my graduate work led me to apply for a program through Shedd, called Teacher Field Experience: Biology in the Bahamas. Through this program, I was able to dive deep into marine environments and scientific research, first in Shedd’s classroom, and then firsthand in the Bahamas aboard Shedd’s research vessel, the R/V Coral Reef II. Through hands-on experience, I gained a greater understanding of data collection and analysis, how it applies to current scientific research and how to integrate it into my classroom curriculum. I quickly realized that teachers and educators can benefit greatly from unique professional development experiences and field work. My experiences on the Shedd’s research vessel created a desire in me to continue doing real, hands-on science, and inspire other educators to improve the science they do in their classroom. Last year I was fortunate enough to accept a learning specialist position at Shedd, which allows me the opportunity to connect with teachers all over the city of Chicago.
The Lake Guardian Sea Grant opportunity came at a perfect time. Shedd Aquarium recently unveiled a renovation of our Local Waters exhibit, titled At Home on the Great Lakes. Since Shedd is committed to education and conservation of the Great Lakes, I am thrilled with the opportunity to be able to board a research vessel and explore ecology, geology, geography, weather, and human impacts on Lake Ontario. Even though I was born and raised in Illinois, I feel that I have a lot to learn about the crucial role that the Great Lakes play in our world. I am looking forward to building my knowledge base on the Great Lakes by receiving firsthand experiences on a working research vessel. I am most looking forward to gaining new resources and discovering stewardship opportunities for students and teachers. Once I return, the knowledge and experiences I gain will be shared with the learning department, and will help to shape future programming at Shedd.”

Hundreds of endangered mussels originally residing in the Allegheny River in Pennsylvania have been relocated to the Vermillion river in Illinois over the last several years, and the project appears to be a great success.
From the Environmental Almanac:
“Over the past three years, scientists from the Illinois Natural History Survey have translocated hundreds of mussels from the Allegheny River in Pennsylvania (where they lived beneath a bridge slated for demolition) to sites on the Middle Fork and Salt Fork of the Vermilion River.
The two species of mussels involved, clubshells and northern riffleshells, are both classified as ‘endangered’ by the federal government, and by dint of that status they are subjects of recovery plans coordinated by the U. S. Fish and Wildlife Service. Those plans call for them to be reestablished throughout their historical range, which includes Illinois…
During the day’s work, a total of 286 tagged mussels were located, just over half of the ones placed there. ‘That’s about what we would expect,’ explained Jeremy Tiemann, the Natural History Survey field biologist who is leading the translocation effort in Illinois. ‘Others may have been so close together or so deep the reader didn’t pick them up. It’s also possible some moved up or downstream a little ways.’”

If you’re headed out to enjoy the weather and the outdoors this holiday weekend, you may want to balance swim time with some time on the beach as water temperatures look to be below average in some areas of Lake Michigan.
“In contrast to air temperatures forecast in the 80s, Lake Michigan water won’t warm up in time for the Thursday holiday, according to the National Weather Service office in Grand Rapids.
Water temperatures in Lake Michigan are 10 to 15 degrees colder than they were this time in 2012 and 5 to 10 degrees colder than they were in 2011, according to meteorologist Evan Webb. He said it’s a product of the cool spring this year.”
Water temperatures may be warmer or cooler at other points on the lake, and there are a number of sites to keep up to date on the conditions. If you’re planning to spend your time near the waters around Michigan City, Indiana, for instance, you can get current and recent nearshore conditions from the buoy operated by Purdue University and Illinois-Indiana Sea Grant.
However you spend time this holiday weekend, enjoy the sights and scenery safely.

The Great Lakes Ecological and Economic Protection Act was introduced by Senators Carl Levin (D-MI) and Mark Kirk (R-IL), co-chairs of the Senate Great Lakes Task Force, along with Senators Debbie Stabenow (D-MI), Amy Klobuchar (D-MN), Sherrod Brown (D-OH), Richard Durbin (D-IL), Al Franken (D-MN), Charles Schumer (D-NY) and Tammy Baldwin (D-WI).
In addition to reauthorizing the Great Lakes Legacy Act, which provides support for communities to clean up waterways that are designated Areas of Concern (AOC) the United States and Canada, the new legislation would continue funding the Great Lakes Restoration Initiative and the EPA Great Lakes National Program Office.
The 10-minute video, produced by Illinois-Indiana Sea Grant and Wisconsin Sea Grant, explores Great Lakes waterways blighted by decades of industrial discharges like heavy metals, oil, and chemicals such as PCBs and PAHs. The 2002 Great Lakes Legacy Act created an initiative to clean up contamination in these AOCs. There are currently 29 AOCs in the United States. The habitat, water, and sediment quality have become severely degraded at these sites.
The video informs anglers, boaters, residents, and local businesses of the benefits that can come from a remediated AOC through the Legacy Act. The procedures and successes are the result of strong partnerships among states, municipalities, non-governmental organizations and businesses. Under this voluntary, collaborative program, the EPA and its non-federal partners have allocated almost $400 million toward sediment remediation.
As of September 2012, the program has removed or capped 2.1 million cubic yards of degraded sediment. But more waterways need to be cleaned up, and community involvement is essential.

Illinois’ beach fronts got a bit of good news last week as a recent report pointed to improving water conditions and reduced contamination.
From The Chicago Tribune:
“The report compiles data on E. coli levels collected by local agencies and submitted to the U.S. EPA. E.coli, which can cause serious illnesses and infection, can be a predictor of other contaminants in the water, said Henry Henderson, Midwest director for NRDC.
Chicago’s Montrose Dog Beach and Rainbow Beach were the most contaminated beaches along Illinois’ Lake Michigan shoreline, according to the report. A variety of factors can change how a particular beach might test on any given day.
The study also found that Illinois’ 65 Lake Michigan beaches saw a combined 334 closings and swimming advisory days last year, a decrease from 483 combined days in 2011. The majority of those closings and advisories were caused by unknown contamination sources, according to the report.”

Illinois-Indiana Sea Grant’s summer interns are already hard at work assisting specialists in several areas, working directly on important issues and getting the public involved in problems facing the Great Lakes.
Alice Denny, one of the interns working with the aquatic invasive species team, has been working with AIS specialist Sarah Zack to bring important invasive species prevention information to fishing tournament organizers and participants. She just recently attended the first of several tournaments slated for this summer, and wrote in to tell us about the internship experience thus far.
“It has been a busy week for me at the AIS office. This summer I am primarily working with fishing tournament organizers and anglers to better understand their attitudes and practices in AIS prevention. Last weekend, I attended my first fishing tournament and had a great time. Although the weather was less than ideal at North Point Marina, Clean Boats Crew and I were able to reach out to the salmon and trout anglers in the Geoffrey Morris Memorial Tournament. Sarah and I attended the rules meeting Friday evening to talk about simple steps tournament anglers can take to prevent the spread of AIS. Then on Saturday I went to the weigh-in to speak with anglers one-on-one and hand out educational material. There were around 70 boats participating in the tournament, with multiple anglers per boat. The audience was receptive and I really enjoyed speaking with them about the importance of AIS prevention. I’ll be attending another tournament in Indiana next weekend, and I’m hoping for nice weather and lots of fish so I can reach as many anglers as possible! Overall I’m really enjoying working with this audience over the summer as I’m getting lots of experience with outreach.”
Several of our interns wrote about their experiences at the IAGLR 2013 conference, and there are many more events and projects they’ll be updating us on throughout the summer.

Recent research has shown that pharmaceuticals and personal care products can cause significant problems for waterways, affecting not only water quality but also negatively impacting the processes that plants and animals need to survive and thrive.
One way that those products are causing pollution in the Great Lakes may not just be due to the chemicals they are made from, though.
From Scientific American:
“Rather, small plastic beads, known as micro plastic, are the offenders, according to survey results to be published this summer in Marine Pollution Bulletin. ‘The highest counts were in the micro plastic category, less than a millimeter in diameter,’ explained chemist Sherri ‘Sam’ Mason of the State University of New York at Fredonia, who led the Great Lakes plastic pollution survey last July. ‘Under the scanning electron microscope, many of the particles we found were perfectly spherical plastic balls.’
Cosmetics manufacturers use these micro beads, or micro exfoliates, as abrasives in facial and body scrubs. They are too tiny for water treatment plants to filter, so they wash down the drain and into the Great Lakes. The biggest worry: fish such as yellow perch or turtles and seagulls think of them as dinner. If fish or birds eat the inert beads, the material can deprive them of nutrients from real food or get lodged in their stomachs or intestines, blocking digestive systems.”
These latest findings help provide additional information on how these common products can cause environmental problems. For more information, read the complete article at the link above and visit our Unwanted Meds website.

Aquatic invaders come in a number of shapes, sizes, and varieties, and aren’t limited to mussels or fish. In addition to our “Be A Hero – Transport Zero” campaign asking boaters and water users to be on the lookout for invasive species, IISG has helped fund “Hydrilla Hunt!,” a program to keep this invasive plant from overtaking Illinois’ waters.
Hydrilla verticillata, commonly known as “hydrilla,” is an aquatic invasive “superweed” – a non-native plant that can grow quickly in waterways and cause serious environmental and economic damages. But before this species takes over, Illinois partners are asking water lovers for their help in preventing hydrilla’s spread.
“Recognized as one of the world’s worst weeds, hydrilla can grow an inch per day and form dense mats of vegetation at the water surface. Within the past few years, hydrilla has been discovered in Wisconsin and Indiana and it is expected to arrive in Illinois very soon. Our desirable native aquatic plants, sport fishing, native wildlife, waterfront property values, and recreational uses might all be seriously impacted.
‘Early detection of hydrilla could save Illinois millions of dollars in control costs,’ noted Cathy McGlynn, coordinator for the Northeast Illinois Invasive Plant Partnership (NIIPP). ‘Experience from other states shows that once a waterway becomes infested with hydrilla, it’s nearly impossible to control. Our hope in Illinois is to identify the plant at a very early stage when populations are still small enough to eradicate and manage,’ added McGlynn.”
Because this species can spread so quickly, the “Hydrilla Hunt!” program is asking boaters, fishermen, swimmers, sailors, and more to help locate it and notify them via e-mail with photos if possible.

Lake Erie, one of the Great Lakes that began to rebound significantly thanks to the Clean Water Act and several cleanup projects, is being threatened by toxic blue-green algae. Fed by fertilizers and runoff, the algae can deplete oxygen levels in the water and be detrimental to the lake’s health.
From The Plain Dealer:
“The Western Basin of Lake Erie, located roughly from Toledo to Huron, is becoming seriously affected with toxic blue-green algae. During the summer months, the algal blooms have been so bad that swimmers have emerged from Lake Erie covered in green slime. So far, swimming in Lake Erie has not been prohibited as it was in Grand Lake St. Mary’s, however, the thick algal blooms are not very inviting to swimmers and tends to affect the taste of our drinking water.
The enjoyment of Lake Erie for boating and fishing has also become hampered by the costs to repair clogged engines and the costs of reduced economic drivers, such as fishing charters and other recreational opportunities. We are dangerously close to severely restricting our use and enjoyment of one of the world’s greatest natural resources.”
