Data associated with the publication: Trends in estuarine pyrite formation point to an alternative model for Paleozoic pyrite burial

This data set contains three components. Component 1 is a set of geochemical data from sediment cores collected from the Chesapeake Bay (Maryland and Virginia, USA). Component 2 is a spreadsheet containing a modified copy of a geochemical dataset downloaded from Phase 1 of the Sedimentary Geochemistry and Paleoenvironments repository (Farrell et al., 2021; doi.org/10.1111/gbi.12462) in August 2023. A text file associated with Component 2 describes how the data in the spreadsheet have been filtered from the original SGP download. Component 3 contains a modified section of code from the COPSE biogeochemical model (Lenton et al., 2018; doi.org/10.1016/j.earscirev.2017.12.004) as well a Matlab file (.mat format) that contains vectors for use in the modified section of code.
