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.</para><para>All files are in csv format.</para></abstract><keywordSet><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; GASES &#x3E; DISSOLVED OXYGEN</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; ALKALINITY</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; CONDUCTIVITY</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; WATER TEMPERATURE</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; pH</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; GROUND WATER &#x3E; GROUNDWATER CHEMISTRY</keyword><keyword>EARTH SCIENCE &#x3E; LAND SURFACE &#x3E; SOILS</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; GROUND WATER</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY</keyword><keywordThesaurus>CATEGORICAL:NONE</keywordThesaurus></keywordSet><keywordSet><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; GASES &#x3E; DISSOLVED OXYGEN</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; ALKALINITY</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; CONDUCTIVITY</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; WATER TEMPERATURE</keyword><keyword>EARTH SCIENCE &#x3E; TERRESTRIAL HYDROSPHERE &#x3E; WATER QUALITY/WATER CHEMISTRY &#x3E; WATER CHARACTERISTICS &#x3E; pH</keyword><keywordThesaurus>VARIABLE:NONE</keywordThesaurus></keywordSet><intellectualRights><para>This work is licensed under the Creative Commons Attribution 4.0 International License.
