Project PI Dr. Guy Meadows looks across the lake surface into a dense fog surrounding R/V Storm. As the AUV missions progressed, the vehicle would periodically surface to update its GPS position. In addition to establishing a wireless connection, the survey team would also attempt to get visual confirmation of the vehicle’s status. This was extremely challenging, however, when socked in with fog. Phase III Summary

Bulk freighter Norman was a large steel vessel, the predecessor to the modern-day Great Lakes Bulk Carrier. In May of 1895, Norman collided with Canadian steamer Jack off Presque Isle; Norman’s hull was broken forward of the boiler house, causing it to sink in nearly 200 feet of water. This sonar image passes closely over the freighter’s stern, showing the side of the aft cabin, the break in the hull, cargo hatches moving forward, terminating at the vessel’s bow. Phase III Summary
