Rime ice coats telemetry system at Mount St. Helens.
To monitor volcanoes, scientists rely on remote monitoring equipment that can operate 24-hours a day and 365-days a year to deliver real-time data. When scientists design and install monitoring stations, they must consider the remoteness of sites, terrain, and winter conditions. Here, rime ice coats a telemetry system that transmits data near Mount St. Helens, Washington. Rime ice can damage structures by its weight and interfere with signal transmission, at times challenging monitoring efforts.
