Pathways to eureka from unexplained phenomena and interdisciplinary approaches to glaciology

Session ID#: 77934

Session Description:
A theme of major advancement in glaciology has been the application of approaches already well-developed in other disciplines – for example, our understanding of the brittle behavior of ice originates from materials science, and representations of ice melanges are based in granular mechanics. Other glaciological discoveries emerge from something unexpected or seemingly out of place. These could include bifurcation points or oscillatory equilibria in modeled or observed systems, behavior at model discontinuities, and/or anomalous signals in field or remote-sensing data such as unconformities in radar images, or any other peculiarities. This session solicits oddities at any stage of discovery, from unexplained anomalies to glaciological paradigm shifters, and contributions that adapt extra-disciplinary knowledge to glaciology.

The purpose of this session is to broaden thinking, encourage creativity, and pose glaciological research puzzles to participants placed in this mindset. It was inspired by the AGU Centennial themes of Transforming Science and Bridging Communities.
