To directly measure fluid and solute fluxes across aquifer/ estuary interface in Guinea Creek, Rehoboth Bay, DE, USA
Location
Guinea Creek tributary, Rehoboth Bay, Delmarva Peninsula, Delaware, United States
Summary
Groundwater geochemistry, surface water quality parameters, and groundwater seepage rates were measured along the South shore of Guinea Creek, Millsboro, DE, USA in June, August, and October of 2015. Parameters included nitrate, ammonium, dissolved carbon and carbon isotopes, trace elements, salinity, dissolved oxygen, oxidation-reduction potential, pH, temperature, water depth, and ultrasonically and manually measured groundwater seepage from seepage meters. ~10 days of semi-continuous groundwater seepage and surface water quality data, and 157 sets of water samples for geochemical analysis were collected.
Info derived
ultrasonic and manual groundwater seepage measurements, surface water quality and tidal elevation, chemistry of interstitial and discharging groundwater
Comments
Used USGS pick-up truck. Sampling equipment also included ultrasonic flow sensor.
This FAN was assigned after the field work was completed.
