An unusually late, cold spring has delayed snow melt in northern Alaska. Our site visit this year included re-installing the methane sensor, calibrating and repairing analyzers and communications equipment, all in winter-like conditions despite it being late May. This will be the second summer of continuous CH4 flux measurement at the Fen moist-acidic tundra site. The instrument was set up well ahead of the melt, so we hope to get some exciting data. Our webcams are all online now, and images are still being harvested by the PhenoCam network.
