CReSIS will host the International Symposium on Radioglaciology, in conjunction with the International Glaciological Society from September 9 to 13, 2013 at the University of Kansas, Lawrence, Kansas. This symposium will take a comprehensive look at the latest technological innovations in radars and signal processing techniques for investigating ice-sheets, glaciers and their geophysical settings, with emphasis on polar and other logistically challenging settings. Recent advances in radio frequency, microwave, and digital technologies have enabled the development of innovative radars that are used to sound and image glacial ice in new ways. This has allowed researchers to produce 3-D images of the ice-bed interface even when that surface is covered by more than 3km of ice. Radars have been developed that can successfully sound most challenging areas such as fast-flowing glaciers and ice-sheet margins. In addition, ultra-wideband radars are being used for fine-resolution mapping of near-surface internal layers in polar firn, for strain rate measurements, ice melt, and other innovative applications. The symposium will cover recent measurements and signal processing advances that are leading to new discoveries. It will also examine the observational needs of the next-generation ice sheet models, and how radioglaciology can support modeling requirements. The overarching purpose of this meeting is to discuss the latest technical improvements in radars and signal-processing techniques for polar research, to present recent measurements, and to report on analyses and interpretations of recent observations. Additionally, the meeting will provide an opportunity to discuss observational requirements for radars that will most benefit and support development and validation of next-generation ice-sheet models.
