Ecological, Sedimentological, and Geochemical Results From 2019 Coring Along Main Creek and Bacon Ridge Branch, 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. The single shapefile included documents the depths cored at both detailed study sites, and their spatial locations. Seventeen comma-delimited tables are included. Fourteen record pollen records at various depths identified within sediment cores taken at this study's two detailed investigation sites: Main Creek, near Pasadena, MD, and Bacon Ridge Branch, near Crownsville, MD. The remaining three include: radiocarbon dates associated with woody material identified in these sediment cores, visible, near-infrared, and X-ray Fluorescence (XRF) information...

Under research permit YELL-SCI-8030, samples from 13 silicified tree remnants were collected adjacent to the Old Faithful Geyser cone in April and November 2019. The silicified wood samples were dated using the radiocarbon (14C) method and were analyzed by scanning electron microscope (SEM) to determine the extent of wood silicification. This study was conducted in order to provide new information on the geyser’s past decadal to centennial eruptive activity. Understanding Old Faithful’s past could provide a baseline for understanding future changes in its eruption intervals.
