Riley, J.W., 2024, Sap Flux and Biophysical Measurements of Select Trees at Panola Mountain Research Watershed, Georgia, 2019: U.S. Geological Survey data release, https://doi.org/10.5066/P92DD6RD.

Summary

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.

Purpose

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.
