Fitting the chine to Hull #1
Today students glued up the bottom and hull stringers. The chine pieces were soaked for 30 minutes in a PVC tube filled with boiling water. This softened the mahogany frames enough for them to bend and twist to fit the shape of the bottom. Next we will glue up the chines and begin to fasten the plywood sides and bottom.

Aquatic Plants Featured at next Great Lakes Seminar


2009-2010 Great Lakes Seminar Series: "Aquatic Plant Survey of Grand Traverse Bay" March 9, 2010


The Inland Seas Education Association will present a seminar that focuses on aquatic plants found in Grand Traverse Bay at 7:00 pm on Tuesday, March 9, 2010, at the Inland Seas Education Center in Suttons Bay. The program will be presented by Sarah U’Ren, Program Director at The Watershed Center-Grand Traverse Bay. This seminar is free and open to the public.During the summer of 2009, the Watershed Center conducted a macrophyte bed survey of Grand Traverse Bay, utilizing aerial photography and their Bay Monitor tugboat. Macrophytes include rooted aquatic plants such as milfoil and algae such as Chara. Additionally, a variety of water quality and sediment tests at various bed locations were conducted to analyze for nutrients such as phosphorus.
Results from this study show a marked increase in the number of beds compared to previous surveys conducted in 1991 and 1998. The study also provides baseline data that will help ascertain the link between macrophyte bed growth, phosphorus cycling, and invasive mussels, as well as any connection to avian botulism.
Sarah U’Ren holds a Master’s degree in Environmental Science from the University of Maryland and has been Program Director at the Watershed Center since 2002. U’Ren authored the Grand Traverse Bay Watershed Protection Plan and administers its many grant-related programs. She also directs the Watershed Center’s beach and volunteer monitoring programs, and launched their Stream Search program in 2003.

Phragmites Seminar Tonight At ISEA

Tonight's Great Lakes Seminar is:

Phragmites Problems & Control in the Grand Traverse Bay Watershed


The Inland Seas Education Association will present a seminar that focuses on the issues surrounding the invasion of Phragmites at 7:00pm on Tuesday, February 9, 2010 at the Inland Seas Education Center in Suttons Bay. The seminar, "Phragmites Problems and Control in the Grand Traverse Bay Watershed," will be presented by Ellen Kohler, Policy Specialist at The Watershed Center-Grand Traverse Bay. This seminar is free and open to the public.Phragmites is one of the highest-threat invasive species in Michigan, and it is quickly establishing itself in this region. Phragmites grows up to 14 feet tall, forms extensive dense stands, and harms native habitat by crowding out native vegetation. It also limits water access, damages property values, blocks views, and is very expensive and difficult to control once well-established. The Watershed Center-Grand Traverse Bay is the lead organization for Phragmites detection and control in Grand Traverse County. The Michigan Department of Natural Resources and Environment received grants to begin Phragmites control efforts in the fall of 2009. However, Phragmites is very aggressive and it will take several years of surveying and additional control measures to contain it.Ellen Kohler is a Policy Specialist at The Watershed Center Grand Traverse Bay. The Watershed Center advocates for clean water in Grand Traverse Bay and acts to protect and preserve the Bay's watershed. They are the leader in protecting and preserving the Bay's watershed and achieving broad community commitment to clean water.
