Our Mission

The Sedimentary Geochemistry and Paleoenvironments Project (SGP) is a research consortium that seeks to address questions of environmental evolution across Earth history through statistical analyses of the sedimentary geochemical record. This search website allows you to search our Phase 2 data product, which was made available in Winter 2025. If you are interested in joining SGP please visit our informational website here.

The SGP wiki, containing information on our SQL database, how we code data, and the data in the Phase 1 and 2 data products, can be found here.

The Phase 2 data product is now openly available. Users downloading and re-using this data in publications should cite Farrell et al., 2021, Geobiology, in their methods sections and note they are using the Phase 2 data. This paper can be accessed here. We are currently in the process of publishing a new citable reference describing the Phase 2 product.
