and Research (SEAMONSTER) project we are establishing a sensor web to monitor the hydrology and mass balance of the 11 square km Lemon Glacier near Juneau, Alaska. We have installed climate stations, one on a ridge above the glacier and a second 3 km below the terminus. An in-situ water quality sonde measures water temperature, conductivity, turbidity, pH, and dissolved oxygen continuously in Lemon Creek, the proglacial stream draining the glacier. In addition, the U.S. Geological Survey maintains a stream gauging station at the location of the sonde. To study glacier lake outburst flood events, we have installed a pressure transducer to monitor stage in a supra glacial lake that forms annually in the spring and early summer and drains in the late summer. A communication system allows data from all of these sensors to be transmitted to our lab at the University of Alaska Southeast in real-time and throughout the
