AB: Understanding subglacial behaviour is vital to our understanding of glacier dynamics and the relationship between climate change and glacier response. Over the last 10 years dramatic advances have been made by examining subglacial behaviour by in situ `wired' instruments. This talk describes a new way of examining the subglacial environment by the insertation of autonomous multi-sensor subglacial probes. These are `wire free' and send data back to the surface by radio transmission. Compared to wired-in probes they behave more like clasts within the subglacial environment. The preliminary findings from the first field season at Briksdalsbreen, Norway will be reported, with data from GPR, ice drilling, till samples and probe insertation.
