Two PhD RAs in Karst Hydrology and Geophysics focusing on geophysical analysis of a karst aquifer. The study will employ fieldwork in the Santa Fe River Sink-Rise system in northcentral Florida. Geophysical responses to recharge events will be monitored using seismometers, tiltmeters, and GPS instruments and interpreted alongside hydrologic and meteorological data to facilitate aquifer characterization and regionally integrated flow monitoring. Implications range
from the development of karst hazards maps, illustrating areas susceptible to sinkhole formation, to subsurface flow monitoring, aiding water supply management. Interested candidates may contact Dr. Andrew Luhmann (
