Resazurin, resorufin, and chloride concentrations for input to resazurin processing rate calculations

Abstract

Included in final_data.csv are data collected during field stream tracer experiments using the resazurin tracer system. The goal of the tracer experiments was to assess differences in hyporheic exchange and aerobic respiration between unrestored control reaches and realigned treatment reaches. This was done on Chester Creek, Keene Creek, Miller Creek, Mission Creek, and Sargent Creek in Duluth, Minnesota in the summer of 2022. This data file contains the pertinent raw and calculated data to generate breakthrough curves used to assess hyporheic exchange and aerobic respiration using the methods in Knapp et al. (2018). Data in nrri_chloride_conc.csv contains the ion chromatograph output information of chloride concentration with batch information, date of analysis, dilution factors, and sample notes.
