  • University of North Dakota researchers have found an expensive buoy on Devils Lake that stopped sending radio reports two months ago.
    Two university flight instructors in a helicopter located the buoy last week hung up in dead trees and stuck in frozen mud along the lake's shoreline, professor Xiadong Zhang told the Grand Forks Herald. The university isn't giving the exact location because the buoy is valuable.
    Officials will attempt to thaw the mud and remove the buoy after the holidays. Zhang said he couldn't get the buoy to budge this week.
    "It's so hard, like concrete," he said of the frozen mud.
    UND's Department of Earth System Science and Policy had been using the $30,000 instrument to monitor water quality in the northeastern North Dakota lake. The buoy was put in the water about two years ago as part of a $3 million project funded by NASA. The goal is to research changes in water saltiness due to flooding and climate change.
    A meteorological sensor attached to the top of the buoy is safe but Zhang worries that the water sensor attached to the bottom has been ruined by the ice.
