Long-term climate trends and urbanization reveal human impacts and decoupling of dissolved organic carbon quantity and composition in streams

This repository contains data, R code, graphical objects, and outputs in Kelley et al. (2025) entitled Climate Change and Urbanization Decouple Dissolved Organic Carbon Quantity and Composition in Streams accepted for publication in Global Biogeochemical Cycles. https://doi.org/10.1029/2025GB008534 In this finalized repository, we provide a detailed meta data file (1_repository_meta_data.xlsx) containing lists and descriptions of all data files, variables, figures, and scripts within. Note that previous versions contained water quality parameters for forms of nitrogen and phosphorus, which have been removed from this final version. These parameters were neither used in any analyses in this work nor underwent QA/QC protocols; thus, we suggest caution in their use from previous versions. Additionally, this repository contains a publication license for a graphical object created using the BioRender platform.
