Dataset: Sediment grain size data collected from a shallow subterranean estuary (STE) in Gloucester Point, Virginia USA, from 2018 to 2019

The grain size of sediment samples was collected from a sandy subterranean estuary (STE) located in Gloucester Point (GP), Virginia, USA. Sediments were measured for grain size with a laser diffraction particle size analyzer (LDPSA, model: LS 13 320, Beckman Coulter). Particle size distributions of GP-STE sediment were determined with an LDPSA using the Fraunhofer Theory. Samples were subsampled from sediment vibracores collected at the GP-STE  in July 2018 and replicate samples (0 centimeters, 50 centimeters, and 100 centimeters) from the January 2019 core. The data output produced by the LDPSA corresponds to the Wentworth scale range of sediment grain size categories. Samples were prepped with 10 percent (%) Calgon solution prior to analysis.
