Data from Dumont et al. (2026), Self- and Electrodic-Potential Response to Hydrological and Biogeochemical Processes in the Soil-Tree Continuum

These data are published in Dumont, M., Takver, X., Jarecke, K., Yilangai, R., Slater, L., Graham, E., Holly, B., Sullivan, P., Singha, K. (2026). Self- and Electrodic-Potential Response to Hydrological and Biogeochemical Processes in the Soil-Tree Continuum. Journal of Geophysical Research-Biogeochemistry, doi: 10.1029/2025JG009375. • We explore the potential of passive electrical methods to concurrently track water and biochemical fluxes across the soil–tree continuum. • We hypothesize and test an electro-hydro-biogeochemical conceptual model using electrical potential monitored within the soil-root-trunk continuum at the H.J. Andrews Experimental Forest, Oregon, USA during the summer of 2023. • Despite disturbances caused by wildfire smoke, electrical signals revealed strong correlations with daily and seasonal tree transpiration, water uptake, hydraulic redistribution, and soil respiration. • This study presents a framework for using passive electrical methods as proxies for monitoring forest ecohydrological sustainability.
