Jeffrey W. Riley 20240513 tabular digital data https://doi.org/10.5066/P92DD6RD This data release contains a zipped folder with two comma delimited data files and two companion metadata files. The data files are: 1.) sap_flux_data.csv and; 2.) biophysical_characteristics_of_instrumented_trees.csv The sap flux data were stored in data loggers every 10-minutes for 15 riparian trees. Sap flux was estimated using heat-pulse velocity sensors at three depths into the xylem of each tree. Sap flux estimates in the data release are 30-minute rolling medians which reduces data spikes that are common in high-frequency sap-flux data. The biophysical measurements are properties of the instrumented trees that allow scaling of sap flux to sap flow and total-tree water-use. These data were collected as part of an investigation of groundwater uptake by riparian trees at the Panola Mountain Research Watershed and were used to investigate transpiration derived from the saturated zone and to compare with other analytical approaches based on water table fluctuation methods. 20190404 20191023 ground condition Complete None planned -84.17931 -84.15270 33.64006 33.62305 ISO 19115 Topic Category biota None forests transpiration sap flux USGS Metadata Identifier USGS:63cae24ad34e06fef14f3f2c None Southeastern U.S. Georgia Panola Mountain Research Watershed None.
