Field Activity 07SGD01

Identifier 07SGD01
Purpose 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
Location Florida Bay, Barnes Sound, Blackwater Sound
Summary 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.
Info 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).
