Data Type(s): Electro-Magnetic: Resistivity, Environmental Data: CTD, Environmental Data: Conductivity, Environmental Data: Radon, Geochemical: Experiments (geochemical), Geochemical: Surveys (geochemical), Location-Elevation: Navigation
Scientific Purpose/Goals: Collection of Radon and Resistivity profiles in Florida Bay and surrounding waters to look for SGD that may be enhancing the recent algal blooms in the region
Vehicle(s):
Start Port/Location: Key Largo, FL
End Port/Location: Key Largo, FL
Start Date: 2007-09-04
End Date: 2007-09-09
Equipment Used: Conductivity, Temperature and Depth (CTD) Logger/Probe, Rad 7 Radon Detector, Peristaltic Pump, Continuous Resistivity Profiler (CRP), YSI 556, GPS
Information to be Derived: Resistivity profiles through various portions of Florida Bay, Barnes Sound and Blackwater sound looking for variations in subsurface resistivity which either represent lithologic or groundwater salinity changes. Radon mapping concurrent with resistivity provides additional data for the detection of enhanced groundwater surface water interaction (SGD).
Summary of Activity and Data Gathered: Approximately 45 line kilometers per day was collected during the study. This included resistivity, radon and continuous surface water quality (salinity, temperature, pH). Shinn, Reich and Hickey installed numerous monitoring wells in Florida Bay in the mid 1990s and were revisited during this trip to collect various groundwater parameters. Wells were selected in the study region of eastern Florida Bay and were sampled for nutrients, trace metals, field parameters (temp, salinity, pH), and Radon and Radium isotopes.
