CMHRP Lidar Coordinator/National Geospatial Program Associate National Map Liaison invited as Keynote speaker for the Management Association for Private Photogrammetric Surveyors 2021 Winter Meeting
Xan Fredericks, Lidar Coordinator for the Coastal and Marine Hazards and Resources Program (CMHRP) and Associate National Map Liaison to Florida, Puerto Rico, and the US Virgin Islands for the National Geospatial Program, has been invited by MAPPS to provide the Keynote during their 2021 Winter Meeting.
Groundwater discharge impacts marine isotope budgets.
Groundwater is an important pathway for materials to flow from land to sea. This is particularly true for materials that are concentrated in groundwater due to chemical interactions between water and aquifer rocks as groundwater flows to the coast.

Increasing threat of coastal groundwater hazards from sea-level rise in California
Projected sea-level rise will raise coastal water tables, resulting in groundwater hazards that threaten shallow infrastructure and coastal ecosystem resilience. Here we model a range of sea-level rise scenarios to assess the responses of water tables across the diverse topography and climates of the California coast. With 1 m of sea-level rise,...
Befus, K.M.; Barnard, Patrick L.; Hoover, Daniel J.; Finzi Hart, Juliette; Voss, Clifford I. Distribution of earthquakes on a branching fault system using integer programming and greedy sequential methods
A new global optimization method is used to determine the distribution of earthquakes on a complex, connected fault system. The method, integer programming, has been advanced in the field of operations research, but has not been widely applied to geophysical problems until recently. In this application, we determine the optimal distribution of...
Geist, Eric L.; Parsons, Thomas E. The predictive skills of elastic Coulomb rate-and-state aftershock forecasts during the 2019 Ridgecrest, California, earthquake sequence
Operational earthquake forecasting protocols commonly use statistical models for their recognized ease of implementation and robustness in describing the short-term spatiotemporal patterns of triggered seismicity. However, recent advances on physics-based aftershock forecasting reveal comparable performance to the standard statistical counterparts...
