USGS staff used historical bathymetric point data from the 1930's (National Oceanic and Atmospheric Administration (NOAA) Office of Coast Survey, see Yates and others, 2017) and light detection and ranging (lidar)-derived data acquired in 2002 (Brock and others, 2006, 2007) to calculate historical seafloor elevation changes in the Upper Florida Keys (UFK) (Yates and others, 2017). Using those changes in seafloor elevation, annual rates of erosion were calculated for 13 habitat types found in the UFK reef tract. The annual rate of mean erosion for each habitat type was applied to a digital elevation model (DEM) extending from Port St. Lucie to Marquesas Key, FL that was modified from the NOAA National Centers for Environmental Information (NCEI) U.S. Coastal Relief Model coastal DEM (NOAA, 2001) to project future seafloor elevation (from 2001) along the Florida Reef Tract. Grid resolution for the DEM is 3-arc seconds (approximately 90 meters (m)). Purpose: These data were used to determine 50-year future seafloor elevation changes (from 2001) along the Florida Reef Tract, based on mean erosion. Supplemental_Information: USGS lidar elevation measurements (used in Yates and others, 2017, 2018) were collected over the Upper Florida Keys using the first-generation National Aeronautics and Space Administration (NASA) Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted on board an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068.

Where elevation inconsistencies occurred, the most recent and/or highest resolution dataset was selected for use in that region. Logical_Consistency_Report: Data cover the area specified for this project, without any known issues. Completeness_Report: This dataset is considered complete for the information presented, as described in the abstract section. Users are advised to read the rest of the metadata record and Yates and others (2017) carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Due to the cell size of the gridded National Ocean Service (NOS) data (NOAA, 2001), assume a horizontal accuracy no better than 3 arc-seconds (or roughly 90 m). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The vertical datum for the source bathymetric data (NOAA, 2001) was generally mean lower low water (MLLW). Source topographic data were in the North American Vertical Datum of 1988 (NAVD88). The differences between these datums are less than the vertical accuracy of the Coastal Relief Model (CRM), consequently, users can assign Mean Sea Level to the CRM, just recognize that the elevation values may not be as accurate as desired. Assume a vertical accuracy no better than 1 m for any elevation values in the CRM. Because of its relatively large cell size (3 arc-seconds or roughly 90 m), no effort was made to establish a common vertical datum as the uncertainty in the elevation value of each cell exceeds the differences between vertical datums (typically sub-meter).

Process_Step: Process_Description: Step 1: The original U.S. Coastal Relief Model Vol.3 - Florida and East Gulf of Mexico DEM was downloaded from https://data.nodc.noaa.gov/cgi-bin/iso?id=gov.noaa.ngdc.mgg.dem:307. The network common data format (netCDF) DEM file was converted to a tagged image file format (TIFF) using Blue Marble Global Mapper version 19.1.0. All remaining steps were completed with Esri ArcGIS Desktop Advanced version 10.6. Using the original TIFF, a footprint of the DEM was created with the "Reclassify (Spatial Analyst)" tool in ArcToolbox by replacing all old data values with 1 and the "No Data" value with 0 to create a raster file. Then, the "Raster to Polygon (Conversion)" tool was used to create a footprint of the original Florida Reef Tract DEM by converting the raster file to a polygon shapefile (SHP). Process_Date: 2018 Process_Step: Process_Description: Step 2: The original Unified Florida Reef Tract Map version 2.0 polygon SHP file was downloaded from http://ocean.floridamarine.org/IntegratedReefMap/UnifiedReefTract.htm. Using Esri ArcGIS, the Artificial, Land, and Mangrove areas (ClassLv2) were removed from the habitat SHP file using the "Select by Attribute" tool to select the three habitat types, and then the Editor Toolbox to delete them. Process_Date: 2018 Process_Step: Process_Description: Step 3: The original Florida Reef Tract DEM TIFF (from Step 1), was clipped to the extent of the modified habitat SHP file (from Step 2) using the "Clip (Data Management)" tool in Esri ArcGIS by specifying the Florida Reef Tract DEM TIFF as the 'Input Raster' and the modified habitat SHP file as the 'Output Extent'. The clipped TIFF was used to extract two shoreline contours with the "Contour List (Spatial Analyst)" tool by adding 'Contour values' for 0-m, 0.05 m and -0.4 m contours. The shoreline contour SHP file was manually connected across inlets and gaps using the "Straight Segment" tool in the Editor Toolbox to draw straight lines between the seaward most points of channels or other breaks along the coastline. The backshore was removed from the contour SHP file by using the "Buffer (Analysis)" tool with a 'Distance Linear unit' of 1000 m. Then, the shoreline contour was smoothed with the "Smooth Line (Cartography)" tool using the Polynomial Approximation with Exponential Kernel (PAEK) smoothing algorithm and a 50-m smoothing tolerance. Using the extended contour SHP file, a polygon SHP file was created using the "Feature to Polygon (Data Management)" tool by specifying the contour SHP file as the 'Input Features', to create the Coastal Clip SHP file. The clipped DEM TIFF was modified further using the "Clip (Data Management)" tool to remove coastal land areas by adding the DEM TIFF as the 'Input Raster' and the Coastal Clip SHP file as the 'Output Extent', creating the FloridaReefTract_ElevationSurface_OriginalClip TIFF. Process_Date: 2018 Process_Step: Process_Description: Step 4: The clipped habitat SHP file (from Step 2) was modified by removing coastal land areas using the "Clip (Analysis)" tool with the habitat SHP file as the 'Input Features' and the Coastal Clip SHP file (from Step 3) as the 'Clip Features', creating the FloridaReefTract_Habitat_Clip SHP file. Process_Date: 2018 Process_Step: Process_Description: Step 5: Mean future elevation for each habitat type in the FloridaReefTract_ElevationSurface_OriginalClip DEM was calculated by applying previously published mean erosion values in the Upper Florida Keys (UFK) that were projected 50 years into the future from the year 2002 (Yates and others, 2018, https://doi.org/10.5066/P9CI9LNH). Mean projected erosion rates in the UFK were compiled by habitat type into a comma separated values (CSV) file using Microsoft Excel 2016. Process_Date: 2018 Process_Step: Process_Description: Step 6: Using the FloridaReefTract_Habitat_Clip SHP file in Esri ArcGIS, individual polygon SHP files were created for each habitat type using the "Select by Attribute" tool and exporting each habitat type as a separate SHP file. Individual DEMs were created from the FloridaReefTract_ElevationSurface_OriginalClip TIFF using the "Clip (Data Management)" tool to clip the full DEM to the extent of each habitat type SHP file by specifying the FloridaReefTract_ElevationSurface_OriginalClip as the 'Input Raster' and the habitat type SHP file as the 'Output Extent'. The "Raster Calculator (Spatial Analyst)" tool was used to project future erosion per habitat type by modifying individual habitat DEMs by adding or subtracting the corresponding 'Mean projected erosion 50 years from 2002 in the Upper Florida Keys (m/50 years)' from the 50_Year_FloridaReefTract_Seafloor_Projection_MeanErosion CSV file. Individual habitat DEMs were merged together using the "Mosaic to New Raster (Data Management)" tool with the 'Pixel Type' set to 32_BIT_FLOAT, 'Number of Bands' set to 1 and the 'Mosaic Operator' set to MEAN to create the final 50_Year_FloridaReefTract_Seafloor_Projection_DEM_MeanErosion TIFF file.
