Sea-Level Geophysics

Along the Gulf Coast, relative sea level rise is impacted by subsidence connected to fluid extraction and land use. As part of local fieldwork, we combine multi-mission InSAR and GNSS observations with drone-borne SAR observations to map contemporary land motion at neighborhood scales. Using Bayesian poromechanical models we can then project subsidence under scenarios of recharge, pumping, and extraction. These modeling and remote observations complement a growing network of GNSS interferometric reflectometry tide-gauge stations our group is building in southeastern Texas. Together, these data and models can be used to represent regional processes contributing to vertical land motion (VLM) in probabilistic sea-level projection frameworks.
