Data and analysis scripts for "Redox-network reconfiguration inferred from the ln[O2]–Eh relationship under mixed-potential conditions in a shallow pond time series"

This repository contains the data and Wolfram Language (Mathematica 12) analysis scripts associated with the manuscript “Redox-network reconfiguration inferred from the ln[O2]–Eh relationship under mixed-potential conditions in a shallow pond time series”. The dataset comprises weekly fixed-depth water-quality observations and biweekly vertical profiles collected at a constructed shallow pond in Japan from July 2022 to March 2024, together with a follow-up vertical-profile survey conducted in February 2025. Measurements include dissolved oxygen (DO), oxidation–reduction potential (ORP/Eh), electrical conductivity (EC), pH, water temperature, and water depth. The archive includes original data spreadsheets, analysis-ready data files, and analysis scripts used for change-point detection, time-series visualization, ln[O2]–Eh regression and residual analyses, and the minimal two-branch mixed-potential model. See README.md for the file structure and data-processing details.
