ABSTRACT:

We conducted a three-year field study from May 2018 to May 2021 at the Santa Fe River Sink-Rise flow system in O’Leno and River Rise Preserve State Parks in north-central Florida, USA, that involved the collection of hydrologic, geophysical, and meteorological datasets and photos. We collected hydrologic data (water level, specific conductance, and temperature) at eight surface water bodies (River Sink, River Rise, and six intermediate karst windows), seven deep wells, and four shallow wells. The Santa Fe River sinks at River Sink, flows through conduits that are ~20 m in diameter and ~30 m below the surface, periodically reemerges at karst windows, and finally emerges at River Rise. We also collected meteorological data at a site in O’Leno State Park (wind speed, gust speed, wind direction, rain, atmospheric pressure, temperature, relative humidity, and dew point). All of the hydrologic and meteorological data are published as a separate, but linked resource in this collection. Our instrument network also included 14 seismometers (12 short period (L-22) and two broadband (CMG 3T) seismometers), four borehole and two platform tiltmeters, and 149 nodal seismometers for a one-month campaign. Bilek (2018) provide the seismic data, and the tilt data will soon be available. Finally, we deployed five motion cameras near seismometer stations to identify sources of seismic signals at the surface. The photos are published here as well as csv files that include the dates, times, and sources of motion that activated the cameras.

ABSTRACT:

We conducted water injection experiments at Bear Spring in southeastern Minnesota. We injected water from a pool into the overflow spring and monitored hydrologic responses at the perennial spring. The experiments were conducted to monitor for seismic signals as water flows through the karst aquifer, and all corresponding seismic data are provided in Bilek (2016). The experiments confirmed that the overflow spring and perennial spring were connected by at least one conduit in the karst aquifer. The overflow spring was dry for the first two experiments, but it started flowing after a large rainfall event. Because the overflow spring was flowing during the third experiment, the water from the pool simply flowed across the overflow spring run instead of entering the conduit. The hydrologic data are provided that illustrate the response to the three injection experiments and the rain event. Information about the field site and the methods are described below.
