NASA’s Operation IceBridge: A Decade of Advances in Observing and Understanding Changes in the Cryosphere from Airborne Remote Sensing
Session ID#: 72795
Session Description:
Since 2009, NASA’s Operation IceBridge (OIB) has surveyed Earth’s polar ice from aircraft in unprecedented detail to monitor ongoing changes in that ice, study the processes that control these changes and connect polar regions with the global climate system. Following the 2018 launch of ICESat-2, the final OIB campaign will take place in fall 2019. This session solicits submissions that synthesize the past decade of OIB airborne observations or identify the key scientific advances that OIB enabled. We encourage submissions that focus on comprehensive syntheses of individual measurement techniques over the mission’s lifetime (e.g., laser altimetry, radar thickness), integrated multi-measurement analyses (e.g., snow thickness on sea ice, bathymetry) or critical shorter periods (e.g., inter-seasonal changes) to better understand the fate of Arctic and Antarctic land and sea ice. Submissions that contextualize OIB’s scientific legacy using results from other airborne campaigns, satellites, ground- and ship-based fieldwork or models are especially encouraged.
