Carbon dioxide is contributing to a change in the chemical makeup of the world’s oceans, which is known as ocean acidification. This process may make it more difficult for shellfish and coral to survive in this new environment. But the oceans may not be the only bodies of water threatened by this dangerous change.
From The Great Lakes Echo:
The increased carbon dioxide changing the water chemistry and ecology of oceans may also be affecting freshwater and the organisms that live in it.
“Based on our preliminary modeling and understanding of carbon cycles, we think similar acidification trends will take place in the Great Lakes to the degree that researchers are expecting in the oceans,” said Galen McKinley, a professor of atmospheric and oceanic sciences at the University of Wisconsin.

IISG’s Caitie McCoy attended the Seventh International Conference on Remediation of Contaminated Sediments last week to present her community outreach work with the Great Lakes Legacy Act (GLLA). The conference traditionally features environmental scientists and engineers, but that is changing. “We are starting to see more attention paid to community engagement at these types of conferences,” Caitie tells us. “Technical project managers realize that projects are easier to implement when the community understands and supports the work, and so they’re eager to learn from professionals who specialize in community engagement and stakeholder involvement.”
Caitie presented a poster on her educational program in northwest Indiana, which taught students about the GLLA sediment cleanup at Roxana Marsh on the Grand Calumet River. Instead of presenting a typical scientific poster full of text and graphs, Caitie displayed a mural that her fourth grade students made to represent the Roxana Marsh ecosystem.
“Some of my colleagues were a bit skeptical about me presenting a fourth grade mural to a bunch of technical folks, but I’m not afraid to shake things up,” Caitie said. “I wanted to use something eye-catching that would draw people’s attention toward my poster.” And it worked. Caitie was visited non-stop during the session and talked to more than 100 conference attendees about her program. When asked if she thought her poster made an impact, Caitie replied, “I would never have dreamed that someday engineers would be asking me how to replicate my educational program at their sites, so I take that as a big success.”
Caitie will expand her programming throughout the Grand Calumet River community in 2013, as the Legacy program begins another phase of dredging this summer.
Today’s blog post features a fun bit of physics from Wired.com’s science blog.
Writer Rhett Allain, professor at Southeastern Louisiana University, received an interesting question over Twitter – “What would happen if everyone on the planet jumped in the water?”
He writes:
“Let’s give a slightly refined version of the question.
‘If everyone on Earth went for a swim at the same time in Lake Michigan, how high would the water level rise?’
I have two primary assumptions to start with. First, I will assume that during this time the volume of water in Lake Michigan will be constant. So if the people make the water level rise, the water level will indeed rise instead of pushing water into the other Great Lakes. Second, I will assume that all of the humans in the lake are floating. If they aren’t ‘swimming’ or touching the bottom, then it will be easier to calculate the rise in the water level.”

The frigid waters of Lake Michigan during a Midwestern winter may not seem very inviting to us, but some species spend a great deal of time there.
From Phys.org:
“On Nov. 2, 2010, Mueller documented 25,555 long-tailed ducks in Lake Michigan.
And on Jan. 20, 2011, 9,311 red-breasted mergansers were tallied.
The data comes from the Lake Michigan Offshore Waterfowl and Waterbird Survey, a project initiated in 2009 by Mueller and Noel Cutright, both of the Western Great Lakes Bird and Bat Observatory in Belgium.
The work is designed to increase the understanding of key offshore Lake Michigan bird habitats, many of which have been lightly studied.”

SeaPerch, a program that brings underwater robotics to classrooms and demonstrates how they can be used for educational purposes, recently held a workshop at the University of Illinois Hydrosystems Laboratory. IISG’s Robin Goettel and Terri Hallesy were among the presenters and they shared a number of educational materials that teachers could combine with their classes’ underwater robots.
Thirteen Champaign-Urbana science teachers were in attendance to learn how to incorporate SeaPerch underwater robots into their classroom curricula. Coordinators from Naval Sea Systems Command – Crane STEM led the morning session to introduce the SeaPerch program, provide helpful tips for constructing the complimentary robot kit each teacher received, and discuss relevant resources for classroom use. Additional robots commonly deployed for scientific applications were also highlighted.
Over lunch, participants interacted with U of I graduate students in engineering to discuss research topics and applications for their in-class lessons. Robin and Terri shared educational resources including two COSEE Great Lakes curriculum collections, Greatest of the Great Lakes: A Medley of Model Lessons, and a Fresh and Salt activity, “I, Robot, Can Do That!”
During the afternoon session, a live demonstration of the SeaPerch robot was conducted and teachers had an opportunity to operate the SeaPerch robots in the large-scale laboratory facilities.
SeaPerch is a joint program of the Office of Naval Research and the AUVSI Foundation. Visit the SeaPerch homepage to learn more about bringing underwater robotics to the classroom, and for a calendar of upcoming workshops and events.
The Paul A. Funk Recognition Award provides a personal award to the winner as well as funds for their department to use in support of their work benefiting natural resources and human environmental systems.
This year, Illinois-Indiana Sea Grant’s Robin Goettel won the award for her extensive educational outreach work, including the creation of numerous curricula for science teachers and others. In particular, the Fresh and Salt curriculum, the Greatest of the Great Lakes collection of model lessons, and The Medicine Chest have helped to inform, engage, and education over 100,000 students about environmental science related to the Great Lakes.
Robin isn’t afraid to get totally immersed in her environmental education work either, as this excerpt from her nomination proves:
“No description of Robin would be complete without a mention of Zelda the zebra mussel, a ‘spokesmussel,’ as Robin describes her. Zelda is a costume that Robin is not afraid to pull out at public events. While maybe not quite ready for Disneyworld, Zelda draws a crowd. People start with a laugh, are compelled to ask questions, and end up with a better understanding of invasive species for the unconventional approach.”
Those examples don’t begin to touch on the work that Robin has engaged in throughout her many years with the program–from direct engagement with students of all grade levels, to educational displays at some of the Midwest’s biggest events, to forging partnerships with other environmental organizations to better educate, inform, and engage people in protecting and preserving natural resources.
Robin’s many years of work on environmental issues, and her dedication to fostering ever higher levels of science education for students of all ages, make her a terrific and very deserving choice for this award.
Phragmites Australis, also know as the Common Reed, is a wetland plant that is not native to the Great Lakes. The invasive plant grows and spreads rapidly in the wetlands around the Lakes, and as a result can crowd out native plants that are beneficial to the local ecosystems.
Researchers at Michigan Tech are working on mapping the spread of the plant, though, in an effort to better understand its spread and plan for managing and reducing it.
From Upper Peninsula’s Second Wave:
“The common reed, or phragmites australis, isn’t native to the Great Lakes, but grows quickly in our climate conditions into large, tall stands that can threaten wetlands habitat.
The plant hasn’t been studied very much, or mapped, which was the goal of the Tech scientists, in cooperation with the U.S. Geological Survey, Boston College and the U.S. Fish and Wildlife Service. Together, teams first mapped the U.S. coastlines of all five Great Lakes using satellites.
Then, they did field studies along the coastlines to confirm the satellite findings, and plot the locations of large stands of the reed, in a first-of-its-kind map.”

Activities associated with the purchase, sale, and use of commercially available organisms or “organisms-in-trade” can potentially result in the introduction of aquatic invasive species (AIS) to waterways such as the Great Lakes. Preventing these introductions is a much more cost-effective way to protect waterways, as opposed to the cost and effort involved in controlling or managing them once they become established.
Building on a University of Notre Dame-led project to examine the environmental risks posed by certain “organisms in trade” (OIT), Illinois-Indiana Sea Grant has been awarded grant funding through the Great Lakes Restoration Initiative (GLRI) for a project titled “GLSGN OIT Initiative – Expanding Risk Assessment Outreach.”
By creating an opportunity to remove these potentially invasive species from circulation, risk assessment is one way to prevent non-native species from becoming invasive. Risk assessment information is also important to AIS education, because studies have shown that education and outreach encourage and shape the behavioral changes necessary for preventing species introduction. For example, horticulturists decided against purchasing a given species once they learned it had the potential to become an invasive species.
This new GLRI grant provides for the creation of new risk assessment and OIT outreach tools including webinars, a training video, non-technical summaries of state laws and regulations, and publications for people involved with fish, reptile, and amphibian commerce. Development of these tools will be guided by a survey that assesses the needs and preferences of OIT user groups. The goal of all these efforts is to reduce the introduction of potentially invasive species, thereby helping to protect and preserve waterways from invasive threats.
This initiative, a collaboration among the Great Lakes Sea Grant Network, North Carolina State University (NCSU), the National Sea Grant Law Center at the University of Mississippi School of Law (NSGLC), and IISG, will also help educate and inform the public about alternatives to high-risk aquarium, water garden, bait, live food, and classroom species.
