Datasheets associated with borehole sampling of surficial sediments in Northern Virginia and Southern Maryland conducted by the U.S. Geological Survey for the Federal Highways Administration Turner-Fairbanks Research Center In Situ Scour Testing Device

This spreadsheet contains the results of open-bore auger samples collected by the U.S. Geological Survey in Maryland and Virginia for the Federal Highways Administration Turner-Fairbanks Highway Research Center. 19 sites were selected in 14 different locations across northern Virginia and southern Maryland by FBGC scientists to drill boreholes for the development of the TFHRC’s In-situ Scour Testing Device (ISTD) and to investigate the sedimentological properties of different layers of the near-surface soil column. Each worksheet in this excel workbook contains the detailed log information for one site, including its name, gps coordinates, surface elevation, borehole depth, information about the drilling rig used to collect the sample, and core observations. Full core logs were not recorded for every site, but the sites where logs were recorded include the sites of Janelia, Moran Landing, Foxboro, Huntley Meadows, Grist Mill, Muddy Hole, Meadowood 1, Meadowood 2, and Algonkian. The data includes general information about the core as well as detailed sediment characteristics, notes and comments on the lithology, whether photos were taken, the number of blows and the N-value of the standard penetration test (SPT), and the amount of sediment recovered of that section of the core. Certain characteristics were not recorded for each core, however the categories of the logs were kept the same for consistency in this report.
