Ecological, Geomorphological, Sedimentological, and Geochemical Records of Pre- and Post-Colonial Riparian Ecosystems in Anne Arundel County, Maryland

This data release includes data collected in the pursuit of identifying pre- and post-colonial riparian ecosystems found throughout Anne Arundel County, Maryland, USA. A single raster file is included, and represents a topological classification of the entire county according to a hydrologically conditioned Digital Elevation Model (DEM). Ten shapefiles are also included, nine of which represent the depths of various soil layers as identified by ground-penetrating radar for two detailed study sites within Anne Arundel County. A tenth documents the depths cored at both detailed study sites, and their spatial locations. Finally, twenty comma-delimited tables are included in this release with fifteen tables documenting pollen records at various depths identified within sediment samples taken throughout the country's flood plains. The remaining five tables include the following: general summary information for all sample sites; radiocarbon dates associated with woody material within the sediment cores; morphological information identifying tree species found buried in-situ throughout the county; visible, near-infrared, and X-Ray Fluorescence (XRF) information associated with each core; and a data dictionary for the previous information.
