The Water Quality of Green Bay

For January 22, 2020                     Please share this invitation with your friends
Hi WN@TL Fans,
The the shape of Wisconsin is happily and historically defined largely by waters that bound it:  The St. Louis, St. Croix, Montreal, Brule, Menominee and Mississippi Rivers, and Lakes Michigan and Superior. 
But it’s Green Bay that gives us our thumb.  
With Green Bay there is much we can grasp about geology, glaciology, hydrology, continental exploration, European colonization, freshwater fisheries, and maritime culture.
With Green Bay we can also put our thumb on what it means to slide from a pristine estuarine place to a Superfund site.
This week (January 22) Julia Noordyk of UW Sea Grant Institute will be here to talk about “The Water Quality of Green Bay:  Past, Present & Future.”  
She writes:
“Since the arrival of the Europeans in the 17th century, the world’s largest freshwater estuary has undergone tremendous ecological changes. The once stunningly clearwater bay, surrounded by wetlands, is now primarily known for its legacy of industrial pollution, blue-green algae blooms and a dead zone. 
“But all is not lost! Today, we are witnessing the largest PCB cleanup in the world in the Fox River and the re-construction of the Cat Island Chain which will provide 242 acres of island habitat for threatened and endangered shorebirds. Join me for a trip through time as we look at the ups and downs of one of Wisconsin’s greatest natural assets: the Bay of Green Bay.”  
About the Speaker:

Julia Noordyk is the Water Quality Outreach Specialist with the University of Wisconsin Sea Grant Institute who works closely with the Clean Bay Backers, a citizen’s advisory committee dedicated to restoring the health of the Fox River and bay of Green Bay. She also focuses on community resilience and reducing stormwater impacts with green infrastructure. 
Julia has a M.S. degree in conservation biology and sustainable development from the University of Wisconsin-Madison and a B.S. in zoology from Colorado State University.

Next week (January 29) Tony Goldberg of the School of Veterinary Medicine will share his work from Wisconsin and around the world in discovering new pathogens in old wildlife.  He writes:
“The race is on to discover the world’s pathogens, driven by new diagnostic technologies and unprecedented access to remote locations. These technologies and field methods are revolutionizing our understanding of the diversity and distribution of wildlife diseases worldwide. This talk describes how such an approach has revealed novel pathogens and their ecological transmission pathways in diverse wildlife systems in Wisconsin and beyond, sometimes by design and sometimes fortuitously. Examples from bald eagles to fish to chimpanzees highlight how the disease impacts the ecology and sustainability of wildlife populations, and how wildlife populations are evolving in response to disease threats. Adoption of such approaches is sorely needed in today’s rapidly changing global environment.”
Of particular interest to me is the description of a new virus found in bald eagles living along the Wisconsin River. It’ll be good stuff.
Hope to see you this week at Wednesday Nite @ The Lab!
