ISEA has had a long working relationship with Northwestern Michigan College in Traverse City. This has continued this week as NMC's Watershed Studies Class, lead by Prof. Colleen Masterson Bzdok sailed aboard the schoolship Inland Seas on Tuesday morning. The class trawled for fish, took samples of the bottom sediments, hauled a net for zooplankton, and used an Alpha Bottle to collect water samples for pH, D. O. and temperature determinations. They also measured the water transparency with a secchi disk (12 meters). We had very little wind to work with, but we did sail, and it was a beautiful day to be on the lake. A second Watershed Class will sail with us on Monday September 14th.

NMC's Water Studies Institute project finds the wreck of the Lauren Castle in Grand Traverse Bay. The tug Lauren Castle, which sank 5 November 1980 off Lee Point near Suttons Bay, lies in water more than 400 feet deep. For details go to

And, finally, ISEA's Executive Director Tom Kelly will present a program today for NMC's new Freshwater Studies program entitled "An Ecological History of the Great Lakes."
