Marina Director Gene Elmer demonstrates how he shuts off individual bubblers at the St. Ignace Public Marina Thursday, February 18. Mr. Elmer has shut off 10 of the marina's 21 bubblers, which use three-horsepower electric motors and air compressors to release air bubbles underwater, preventing ice formation around the floating docks. Six of the bubblers he shut off will remain off for the entire winter and four more, turned off Thursday, will stay off as long as the weather stays warm enough to allow it. By reducing the number of bubblers running in the $100,000 system, Mr. Elmer said he can save on the marina's winter electrical costs.
