Description:
Explore geodetic techniques for monitoring water-driven dynamics in aquifers and ice sheets in this 49-minute AGU conference talk. Delve into the mechanics of aquifer systems, comparing poroelastic and inelastic responses to groundwater fluctuations. Examine the long history of inelastic subsidence in the San Joaquin Valley and learn how to characterize groundwater fluctuations at seasonal and drought timescales. Discover methods for mapping spatially-variable elastic storage properties of aquifers and understanding poroelastic deformation due to long-term groundwater decline. Investigate the expansion of supraglacial lakes in Greenland and their impact on ice dynamics. Learn about the 2022-2023 GNSS campaign in Western Greenland and how on-ice GNSS is used to track ice dynamics and supraglacial lake drainages. Gain insights into interpreting displacement signals from supraglacial lake drainage events and estimating large-scale elastic loading deformation using GRACE satellite data.
