Location: Elmwood Township Harbor
Depth: Approximately 15 ft
Environmental Conditions: The first thaw of the year (Air temp 50 degrees) with sunny skies. Ice is just beginning to recede around shore and docks.
During the winter dockage systems are subject to Ice damage from the adjacent freezing water. A pressurized air system “bubbles” the dock system to keep ice from forming and potentially crushing the docks. Student built ROVs can be used for dock inspection and examination of the health of the bubble system. On occasion you may be able to see ice formations on the surface. Also note the difference in illumination when looking into the sun and then again away from the sun which tends to challenge the camera. Clip#1 shows the ice shelf of the frozen harbor looming about 5-10 ft from the docks. During the dead of winter the ice will form just inches from the dock. Also notice the formation of zebra mussel formations on some of the bubble lines.
