A wireless subglacial probe for deep ice applications
We present the design and first results from two experiments using a wireless subglacial sensor system (WiSe) that is able to transmit data through 2500m thick ice. Energy consumption of the probes is minimized, enabling the transmission of data for at least 10 years. In July 2010 the first prototyp...

We present the design and first results from two experiments using a wireless subglacial sensor system (WiSe) that is able to transmit data through 2500m thick ice.
