AB: This paper presents the results from eight subglacial wireless probes inserted into the till and ice beneath Briksdalsbreen during summer 2004. This is a new technique in glaciology, to understand glacier processes, and the relationship between glacier dynamics and climate change. These probes were installed in the ice where it was approximately 70m deep and they record temperature, pressure, stress, outside resistivity and tilt. The sensors are held within a small probe which mimics a natural clast. They send their data back by radio communications to a Base Station on the surface of the glacier, which is then sent to the Internet as part of an Environmental Sensor Network. Data was also collected from the surface of the glacier (weather, ice movement, images). Once the probes were installed they began to transmit their data immediately. This is combined with other data (GPR, video camera images and sediment sampling) to investigate the processes occurring beneath a temperate glacier resting on a thin deforming bed.
