Sediment and Radiochemical Characteristics from Shore-Perpendicular Estuarine and Marsh Transects in the Grand Bay National Estuarine Research Reserve, Mississippi

To examine sediment transport and provenance between a marsh and estuary, surface sediments were collected along two transects in the Grand Bay National Estuarine Research Reserve, Mississippi (GNDNERR). Each shore-perpendicular transect consisted of fifteen surface samples, collected every 2.5 meters (m) from 10-m out into the estuary to 25-m into the marsh from the shoreline. Sediment samples were analyzed for their physical and radiochemical properties or signatures. Sediment samples were collected during U.S. Geological Survey (USGS) field activity number (FAN) 2017-315-FA (alternate FAN, [altFAN] 17CCT02) in April 2017. Marsh and estuarine surface samples were collected as part of the St. Petersburg Coastal and Marine Science Center (SPCMSC) Estuarine-MaRsh Geology (EMRG) research project.
