C14A:
Glacier Processes from Large-Scale Remote Sensing I


Submit an Abstract to this Session


Session ID#: 60413

Session Description:
In glaciology, as in many fields, the rate of data production has reached a pace that often exceeds the rate of insight generation. A wide array of earth-observing satellites allow scientists to investigate glacier processes over larger spatial scales at higher temporal resolution than ever before. However, extracting process understanding from this rich data record remains a challenge.

Deeper understanding of glacier processes is critical for accurately assessing and predicting current and future glacier change and associated downstream impacts. In this session, we seek studies that exploit the wealth of remote sensing data to increase our understanding of glacier processes, including: basal motion, calving, grounding line migration, elevation change, ice flow, surging, and mass balance. We particularly seek large spatial and/or temporal scale studies that characterize process variability and its controlling physical factors. We also solicit studies using innovative analysis techniques, such as cross-sensor approaches, machine learning, and modeling-aided interpretation.
