Abstract

Geophysical surveys add value to biogeochemical studies because of their ability to characterize systems remotely, and their precise time resolution. One limitation, however, is their lack of biogeochemical process specificity. Here, electrochemical time series from an oxic-anoxic cyclical bioreactor experiment were reanalyzed with detrended fluctuation analysis (DFA) to distinguish dominant biogeochemical processes. Measurements of EH, pH, dissolved oxygen (DO) were recorded every 20 minutes for 74 days. The time series were divided by geochemical environment (aerobic respiration, NO3- reduction, mixed Fe(III), Mn(IV), SO42- reduction, and a...  more
