The Sedimentological Characteristics and Radiochemistry Data for the Marshes on Dauphin Island, Alabama

By Alisha M. Ellis, Christopher G. Smith, and Marci E. Marot

USGS, St. Petersburg, Florida

Summary

Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center collected push cores from the marshes of Dauphin Island, Little Dauphin Island, and Cedar Key, Alabama in August, 2015 (U.S. Geological Survey Field Activity Number 2015-322-FA). Sample sites varied between high marshes, low salt marshes, and sand flats. This report serves as an archive for the sedimentological and geochemical data derived from the marsh cores and select surface data from the corresponding marsh core sites. Downloadable data are available and include Excel spreadsheets, JPEG files, and formal Federal Geographic Data Committee metadata For further information regarding data collection and/or processing methods refer to USGS Open-File Report 2017–1165 (https://doi.org/10.3133/ofr20171165) and Data Series 1046 (https://doi.org/10.3133/ds1046).
