Title: Integrating geological realism into subglacial investigations

Abstract: The conditions beneath ice sheets play an important role in governing ice sheet behavior and determining their vulnerability to climate change. However, these subglacial conditions are challenging to resolve at the scale and resolution required to capture critical basal processes. Geostatistical simulation can be used to address this challenge by providing a mechanism for filling gaps in observations, introducing geologically realistic textures into models of the subsurface, and quantifying uncertainty. Furthermore, geostatistical simulation can be used within a Markov Chain Monte Carlo framework to produce more rigorous geophysical inversions for basal conditions. These approaches present new opportunities for resolving basal conditions and provide insights into the dynamic behavior of our ice sheets.
