The data was generated as part of the work targeting the overarching research question for the SLAC SFA: How do ubiquitous subsurface interfaces mediate molecular-scale biogeochemical processes and groundwater quality in floodplains and watersheds? The data package includes 5 data files, one for each measured variable: specific conductivity, pH, dissolved oxygen, water temperature and alkalinity. All measurements were recorded in the field immediately after water sampling. Groundwater samples were extracted from a network of installed rhizons (Rhizosphere Research Products, part no. 19.60.21F, 0.6 micrometer mesh size) and piezometer wells within the floodplain. In addition to the data files, there is a terminology file explaining the terms used, a file level metadata file, and a sensor file with metadata about the sensors used.All files are in csv format.EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > GASES > DISSOLVED OXYGENEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > ALKALINITYEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > CONDUCTIVITYEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > WATER TEMPERATUREEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > pHEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > GROUND WATER > GROUNDWATER CHEMISTRYEARTH SCIENCE > LAND SURFACE > SOILSEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > GROUND WATEREARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRYCATEGORICAL:NONEEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > GASES > DISSOLVED OXYGENEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > ALKALINITYEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > CONDUCTIVITYEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > WATER TEMPERATUREEARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > WATER CHARACTERISTICS > pHVARIABLE:NONEThis work is licensed under the Creative Commons Attribution 4.0 International License.

Specific conductivityWater samples were filtered in-situ through installed 0.6 micrometer rhizon membranes and measured with a Thermo Sci Orion DuraProbe 4-Electrode conductivity cell. Analysis occurred immediately after extraction.2. pHWater samples were filtered in-situ through installed 0.6 micrometer rhizon membranes and measured with a Thermo Sci Orion Triode 3-in-1 probe. Analysis occurred immediately after extraction.3. TemperatureThe probe ending for a Digi-Sense Thermistor was routed to the bottom of the well and measurements were allowed to stabilize for 1 minute until taking a final measurement.4. Dissolved OxygenWater samples were filtered in-situ through installed 0.6 micrometer rhizon membranes and analyzed using CHEMetrics K-7553 and K7513 test kits (see CHEMetrics website for test kit sampling procedure). Test kits were measured using a CHEMetrics V-2000 photometer.6. AlkalinityWater samples were filtered in-situ through installed 0.6 micrometer rhizon membranes and analyzed using CHEMetrics K-9810 and K-9815 test kits (see CHEMetrics website for test kit sampling procedure).
