This data set provides tracer parcels to simulate sea ice advection paths in the Northern Hemisphere combined with sea ice concentration data. Sea ice parcels are identified in 25 km grid cells...
-
Three wells in New Hampshire were sampled bimonthly over three years to evaluate the temporal variability of arsenic concentrations and groundwater age. All samples had measurable concentrations...
-
This dataset provides groundwater age estimates for 203 wells used as public- and domestic-supply in two selected areas of California. Groundwater ages were estimated by calibration of...

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed historical produced water chemistry data and ancillary oil well...
-
We computed mean groundwater ages and age distributions at eight wells by calibrating lumped parameter models (LPMs) to concentrations of tracers (3H, CFCs, SF6) in samples using the computer...

Residence time distribution (RTD) is a critically important characteristic of groundwater flow systems; however, it cannot be measured directly. RTD can be inferred from tracer data with...
-
Continuous monitoring and discrete water-quality sampling were coupled in a karst aquifer to assess drivers and timescales of water-quality change. Water-quality data included environmental...
