Description:
Abstract:
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify the combined effect of all constructive and destructive processes on modern coral reef ecosystems by projecting future regional-scale changes in seafloor elevation for several sites along the Florida Reef Tract, Florida (FL) including the shallow seafloor along Key West, FL. 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 Big Pine Key to Marquesas Key, FL that was modified from the NOAA National Centers for Environmental Information (NCEI) Key West coastal DEM (NOAA, 2011) to project future seafloor elevation (from 2011) along the Key West section of the Florida Reef Tract. Grid resolution for the DEM is 1/3 arc-second (approximately 10 meters).
Purpose:
These data were used to determine 50-year future seafloor elevation changes (from 2011) along the Key West section of 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.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of bathymetric and topographic features in the DEM (NOAA, 2011) is dependent upon the accuracy of the input datasets used to determine corresponding cell values. Topography: Positional accuracy of input topographic datasets limits accuracy of corresponding cell values in the DEM. South Florida Water Management District (SFWMD) lidar DEM: 1.15 meters; U.S. Geological Survey National Elevation Dataset (USGS NED) DEM: 10 meters. DEM cell-value relative-contribution factors: SFWMD: 10; NED: 1. Bathymetry: less than 1 meter to tens of meters. Positional accuracy of input bathymetric datasets limits accuracy of corresponding cell values in the DEM. National Ocean Services (NOS): less than 1 meter to tens of meters; Multibeam surveys: 30 meters. U.S. Army Corps of Engineers (USACE) surveys: less than 1 meter. DEM cell-value relative-contribution factors: NOS surveys: 10; Multibeam surveys: 1; USACE surveys: 10; Electronic Navigational Charts (ENC) soundings: 1.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical accuracy of bathymetric and topographic features in the DEM (NOAA, 2011) is dependent upon the accuracy of the input datasets used to determine corresponding cell values. Vertical accuracy of input topographic datasets limits accuracy of corresponding cells in the DEM. SFWMD lidar DEM: 0.18 to 0.36 meters; USGS NED: 7 to 15 meters. DEM cell-value relative-contribution factors: SFWMD: 10; NED: 1. Bathymetry: 0.3 meters to 5% of water depth. Vertical accuracy of input bathymetric datasets limits accuracy of corresponding cells in the DEM. NOS: less than 1 meter to tens of meters; Multibeam surveys: less than 1 meter to tens of meters; USACE surveys: less than a meter. DEM cell-value relative-contribution factors: NOS surveys: 10; Multibeam surveys: 1; USACE surveys: 10; ENC soundings: 1. Gridding interpolation to determine cell values between sparse NOS hydrographic soundings in deep water degrades the vertical accuracy of deep-water elevations.

This data release contains the UFK projected seafloor elevation change for 13 habitat types that were applied to the Key West DEM.
Process_Step:
Process_Description:
Step 1: The original Key West 1/3 arc-second NAVD 88 Coastal DEM was downloaded from https://data.nodc.noaa.gov/cgi-bin/iso?id=gov.noaa.ngdc.mgg.dem:3121. 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 Key West DEM by converting the raster file to a polygon shapefile (SHP).

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 original habitat SHP file was modified using the "Clip (Analysis)" tool to clip the habitat SHP file to the extent of the original Key West DEM footprint (from Step 1) by specifying the habitat SHP file as the 'Input Features' and the DEM footprint SHP file as the 'Clip Features'. Then 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 the "Editor Toolbox" to delete them.
Process_Date: 2018
Process_Step:
Process_Description:
Step 3: The original Key West 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 Key West 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 a 0.05-meter (m) contour. 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 KeyWest_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 KeyWest_Habitat_Clip SHP file.
Process_Date: 2018
Process_Step:
Process_Description:
Step 5: Mean future elevation for each habitat type in the KeyWest_ElevationSurface_OriginalClip DEM was calculated by applying previously published mean erosion rates 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 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 KeyWest_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 KeyWest_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 KeyWest_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 rates 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_KeyWest_Seafloor_Projection_MeanErosion CSV file. For habitats present in the KeyWest_Habitat_Clip SHP file, but not present in the UFK (Dredged/Excavated and Reef Rubble with Seagrass), the mean erosion rate for the total UFK study site was applied. 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_KeyWest_Seafloor_Projection_DEM_MeanErosion TIFF file.
