“…This finding suggests that precipitation water exchanged with salt marsh porewater, diluting the
concentration. This result agrees with previous observations of multilevel decomposition of continuous redox potential measurements across this salt marsh transect during a precipitation event that showed precipitation water changed redox potential at depth (Grande, Arora, Visser, et al,
2022; Grande, Arora, & Zimmer,
2022). These interactions occur at relatively short timescales because we see a relatively instantaneous dilution pattern during the storm event in the
time series that recovered quickly post event.…”
