The research team (including Mark Behn, standing here near a meltwater stream) set up a variety of instruments on the ice to learn about supraglacial lakes. These included GPS stations to track the movement of the ice; seismometers to record vibrations from "icequakes" that occur when cracks form beneath supraglacial lakes and drains the lakes: weather stations; and pressure loggers to measure changes in lakes levels over the year.
