We have openings for two PhD (or exceptional MS) students at New Mexico Tech and one undergraduate student at the University of Florida to monitor geophysical responses to recharge events in a karst aquifer in Florida (funded by NSF Hydrologic Sciences). The students will use geophysical, hydrologic, and meteorological data to characterize karst conduits, subsurface flow dynamics, and the larger karst aquifer system and will collaborate with Andrew Luhmann, Susan Bilek, and Ronni Grapenthin at New Mexico Tech and Jonathan Martin at the University of Florida. Click here for the project abstract for more information. The students will ideally start in Summer 2018. Please contact me if you are interested.
The project will be conducted at the Santa Fe River Sink-Rise system in north-central Florida. River Rise photo from https://www.floridastateparks.org/park/River-Rise.
Field experiment that demonstrated that recharge events generate seismic signals in karst aquifers.
Seismometers (shown as red triangles), tiltmeters (shown as black hollow circles), and GPS stations will be deployed around the Santa Fe River Sink-Rise system to monitor geophysical responses as water levels rise and fall with recharge events. In addition, instruments will be deployed to collect hydrologic and meteorological data. Figure modified from Moore et al. (2009).
