Data Repository associated with: High-resolution record of global cooling during a large Mississippian positive carbon isotope excursion

Github repository for Anderson, N.T., Bergmann, K.B., Braun, M.G., Griffith, E.M., Saltzman, M.R., 2025. High-resolution record of global cooling during a large Mississippian positive carbon isotope excursion. Earth and Planetary Science Letters. This repository contains the data, code, and figures supporting our study of Mississippian carbonates in the Briggs Woods core in Iowa. Our research integrates sedimentological observations, geochemical data, and isotopic analyses to evaluate the effects of multiple processes: temperature change, water changes, and diagenetic alteration. Contents: code/: Python scripts for data analysis and figure generation. data/: Contains processed datasets for petrographic and isotopic analyses. data/photomicrographs: corresponding GPS locations for all sample sites in Excel format data/stitched_photomicrographs: A composite stratigraphic column. Detailed drawn stratigraphic columns in PDF format. data/sem_eds: BSE images and EDS elemental maps from various samples. data/clumped_isotope_results: Processed and raw datasets of clumped isotope measurements from Mississippian samples collected at MIT. Includes raw voltage data for each analysis and processed outputs from ClumpyCrunch and BLIMP, as well as plots summarizing standards and results, in CSV, HTML, and PNG formats.
