Information regarding methodology can be found in Sections 3, S1, S4-5, and S8-9 of the associated publication. Much of the information included in this file is also listed in Appendix A of the associated publication. The data from this study are reported in the NAD 83 (CORS 96) datum, with elevations relative to mean sea level using the NAVD 88 vertical datum (GEOID09 geoid model). The column headings for the tabular data are defined as follows: SHORE_ID shoreline identification number, numbered 1 through 178 LAT latitude (decimal degrees) LON longitude (decimal degrees) ELEV_DGPS mean dGPS elevation of the shoreline indicator of each shoreline feature ELEV_STDEV standard deviation (1-sigma range) of dGPS elevation NUM_PTS number of measurements included in mean elevation calculation TYPE shoreline type, where 1 = gravel barrier, 2 = depositional terrace, 3 = incised alluvial fan CONF level of confidence on a scale of 1 through 4, with 4 representing the greatest confidence ELEV_SWL corresponding estimate of the elevation of the SWL SWL_STDEV standard deviation of SWL elevation estimate CURREY_ID identification number of corresponding data from Currey (1982), if available CURREY_ELEV shoreline feature elevation by Currey (1982), if available; reported in the NGVD 29 vertical datum CURREY_ERR error of shoreline feature elevation by Currey (1982), if available CURREY_METHOD method of measurement used by Currey (1982), where 1 = photo-mapping on the best available aerial photos and topographic maps at the time; 2 = field-checked with "rough-and-ready" closed hand level surveys relative to known-elevation benchmarks; and 3 = field checked with a telescopic alidade SAME_FEAT for comparison with Currey (1982); indicates if measurements were made on the exact same feature (yes) or on separate, but nearby features (no) ELEV_NG29 for comparison with Currey (1982); conversion of this study's shoreline elevation data (ELEV_DGPS) to the NGVD 29 vertical datum DEM_10M mean elevation of the shoreline indicator of each shoreline feature according to the 10 m DEM by the National Elevation Dataset assembled by the USGS DEM_10M_STDEV standard deviation (1-sigma range) of 10 m DEM mean elevation DEM_30M mean elevation of the shoreline indicator of each shoreline feature according to the 30 m DEM by the National Elevation Dataset assembled by the USGS DEM_30M_STDEV standard deviation (1-sigma range) of 30 m DEM mean elevation DEM_90M mean elevation of the shoreline indicator of each shoreline feature according to the 90 m DEM from Shuttle Radar Topography Mission (SRTM) DEM_90M_STDEV standard deviation (1-sigma range) of 90 m DEM mean elevation --------------------------------------------------------------- DOCUMENTATION FOR 'bonneville_shoreline_feature_elev_cychen_v1' --------------------------------------------------------------- These GIS data files contain the same tabular information listed in the tabular data files called 'bonneville_shoreline_feature_elev_table_cychen_v1'. Information regarding methodology can be found in Sections 3, S1, S4-5, and S8-9 of the associated publication. The data from this study are reported in the NAD 83 (CORS 96) datum, with elevations relative to mean sea level using the NAVD 88 vertical datum (GEOID09 geoid model). Null value = -9999. The KMZ file was generated by converting the ESRI shapefile into a KMZ file in ArcMap 10.4.1. ---------------------------------------------------------- DOCUMENTATION FOR 'bonneville_shoreline_outline_cychen_v1' ---------------------------------------------------------- These GIS data files represent the reconstructed shoreline of the Bonneville shoreline. Each segment is meant to capture the location of the shoreline indicator of each segment of shoreline. Information regarding methodology can be found in Sections 3 and S5-6 of the associated publication. The data from this study are reported in the NAD 83 (CORS 96) datum, with elevations relative to mean sea level using the NAVD 88 vertical datum (GEOID09 geoid model). Null value = . The column headings of the datasets are as follows: TYPE indicates the shoreline type represented by each particular segment of the shoreline outline; (1) gravel barrier, (2) depositional terrace, (3) or incised alluvial fan METHOD describes the sources of data and observations used to construct the particular segment of the shoreline outline; the phrases below may appear in this column on their own or with others, indicating that multiple sources were used in determining the best trace for the segment: 'aerial' modern aerial and satellite imagery were referenced and examined for geomorphic evidence of shoreline features 'old aerial' old aerial imagery was referenced due to modern human disturbance of the landscape (e.g., farms, quarries) 'no contour' the shoreline feature is discernible with little uncertainty in aerial imagery and traced by photo- interpretation, OR field dGPS measurements and observations constrain the location of the shoreline indicator on the shoreline feature 'XXXX m contour' the contour line of XXXX m elevation (30 m NED DEM) is used to represent this segment of shoreline due to the poor or non-existent geomorphic expression of shoreline features in aerial imagery; the elevation of the contour line was based on the measured elevation of shoreline indicators located in the vicinity of the segment 'inferred' aerial imagery does not show distinct geomorphic evidence of shoreline features along this segment, but adjacent segments for which the interpretation of shoreline features is better constrained allow for the inference of the shoreline indicator location for this area; the area may have been disturbed by clear post-depositional erosion by natural processes (e.g., alluvial washes) or human impacts (e.g., farmland) VISITED a value of 'yes' indicates that this feature was field verified, either by a physical visit to the feature or an examination from a distance SHAPE_LENGTH length of shoreline segment (decimal degrees); this column is auto-populated by ESRI ArcMap 10.4.1 ------------------------------------------------------------------ DOCUMENTATION FOR 'bonneville_shoreline_outline_pts_cychen_v1.csv' ------------------------------------------------------------------ This dataset is a tabular list of 1000 pairs of latitude and longitude coordinates that describe equally-spaced locations along the reconstructed Bonneville shoreline outline. This list of coordinates was made with the intention of providing the broader community with a way to easily plot the outline of the maximum lake extent of Lake Bonneville. The list was generated in ESRI ArcMap 10.4.1 using the 'Construct Points' feature in the Editor Toolbar on the bonneville_shoreline_outline_cychen_v1.shp feature class. The data from this study are reported in the NAD 83 (CORS 96) datum, with elevations relative to mean sea level using the NAVD 88 vertical datum (GEOID09 geoid model). --------------------------------------------------------- DOCUMENTATION FOR 'bonneville_vol_NAD83_CORS96_cychen_v1' --------------------------------------------------------- These data files represent the ballpark estimate of lake volume of the Bonneville shoreline derived from the shoreline feature elevation measurements and the reconstructed Bonneville shoreline outline. Information regarding methodology can be found in Sections 3 and S7. The .tif file is a georeferenced raster file representing a map of lake depth for the lake occurring at the Bonneville lake stage (Figure S6). The .txt file lists in columns the latitude, longitude, and estimated lake depth represented in each pixel of the .tif file. ------------------------------------------------------------------------------------------- DOCUMENTATION FOR 'antelope_drone_dsm_maloof_v1.tif' and 'antelope_drone_rgb_maloof_v1.tif' ------------------------------------------------------------------------------------------- We refer the reader to Section S2 of the associated publication for detailed methodology on the survey of Bonneville shoreline features at Antelope Island (Utah) using unmanned aircraft. The data from this study are reported in the NAD 83 (CORS 96) datum, with elevations relative to mean sea level using the NAVD 88 vertical datum (GEOID09 geoid model). ------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------ ACKNOWLEDGEMENTS: The bulk of this research was conducted as part of an undergraduate senior thesis completed in 2013, and primarily was funded by the following sources: the Department of Geosciences at Princeton University; the Round Table Senior Thesis Fund from the Office of the Dean of the College at Princeton; and the Princeton Energy Grand Challenge Initiative.
