    • Wetland Paleoecological Study of Coastal Louisiana: Surface Sediment and Diatom Calibration Dataset

    Metadata Updated: November 13, 2025

    Wetland sediment data was collected from coastal Louisiana as part of a pilot study to develop a diatom-based proxy for past wetland water chemistry and the identification of sediment deposits for tropical storms. The complete dataset includes forty-six surface sediment samples and nine sediment cores. The surface sediment samples were collected in fresh to brackish marsh throughout the southwest Louisiana Chenier plain and are located coincident with Coastwide Reference Monitoring System (CRMS). Sediment cores were collected at Rockefeller Wildlife Refuge. The data described here include both sedimentary properties and diatom species counts for the surface sediment samples.
