Record low sea ice in 2018 sent ripples through the entire Arctic ecosystem. Peggy’s data were a bit of a shock. From an anchored vantage point in an expanse of the southeastern Bering Sea west of Alaska, Peggy, or mooring M2, had monitored conditions in the water for 25 years. A line of sensors extended down more than 70 meters to where Peggy was tethered to the seafloor, collecting information on temperature, salinity and other properties of the water.
