USGS SPCMSC staff used seafloor elevation-change data from Yates and others (2017a) derived from an elevation-change analysis between two elevation datasets acquired in 1938 and 2004 using the methods of Yates and others (2017b). A seafloor stability threshold was determined for the 1938-2004 Looe Key elevation-change dataset based on the vertical uncertainty of the 1938 historical hydrographic survey and 2004 digital elevation model (DEM). Five stability categories (which include, Stable: 0.0 meters (m) to ±0.24 m or 0.0 m to ±0.49 m; Moderately stable: ±0.25 m to ±0.49 m; Moderately unstable: ±0.50 m to ±0.74 m; Mostly unstable: ±0.75 m to ±0.99 m; and Unstable: ±1.00 m to Max/Min elevation change) were created and used to define levels of stability and instability for each elevation-change value (1,687 data points) based on the amount of erosion and accretion during the 1938 to 2004 time period. Seafloor-stability point and triangulated irregular network (TIN) surface models were created at five different elevation-change data resolutions (1st order through 5th order) with each resolution becoming increasingly more detailed. The stability models were used to determine the level of seafloor stability at potential areas of interest for coral restoration and ten habitat types found at Looe Key. Stability surface (TIN) models were used for areas defined by specific XY geographic points, while stability point models were used for areas defined by bounding box coordinate locations. This data release includes ArcGIS map packages containing the binned and color-coded stability point and surface (TIN) models, potential coral restoration locations, and habitat files; maps of each stability model; and data tables containing stability and elevation-change data for the potential coral restoration locations and habitat types. Data were collected under Florida Keys National Marine Sanctuary permit FKNMS-2016-068. Coral restoration locations were provided by Mote Marine Laboratory under Special Activity License SAL-18-1724-SCRP. Purpose: These data were used to identify areas of seafloor elevation stability and instability, from 1938 to 2004, at Looe Key, FL.

Process_Step: Process_Description: Step 1: The original 1938-2004 Looe Key elevation-change points (1938_2004_LooeKey_SeafloorStability_Points shapefile) were processed and published by Yates and others (2017a). For more information on the elevation-change data processing steps, source elevation data, and elevation-change points, see Yates and others (2017a). Horizontal coordinates of the original 1938-2004 elevation-change points are referenced to the North American Horizontal Datum of 1983 (NAD83), National Readjustment of 1986 and vertical coordinates are referenced to the North American Vertical Datum of 1988 (NAVD88), GEOID03 geoid model. Using VDatum version 3.9, a publicly available software from the National Oceanic and Atmospheric Administration (NOAA) (https://vdatum.noaa.gov/), the 1938_2004_SeafloorStability_Points shapefile was transformed from the NAD83 to the NAD83 National Spatial Reference System of 2007 (NSRS2007) National Readjustment horizontal datum, and from GEOID03 to the GEOID12B geoid model. Process_Date: 2020 Process_Step: Process_Description: Step 2: An elevation-change surface model was created in Esri ArcGIS Desktop Advanced version 10.6 (ArcMap) using the calculated elevation-change (Diff_m) points from the 1938_2004_LooeKey_SeafloorStability_Points shapefile and methods of Yates and others (2017b). The TIN was created using the “Create TIN (3D Analyst)” tool by specifying the 1938_2004_LooeKey_SeafloorStability_Points shapefile as the “Input Feature Class”, Diff_m as the “Height Field” and Mass_Points as the “Type”, creating the 1938_2004_LooeKey_SeafloorStability_TIN file. The 1938_2004_LooeKey_SeafloorStability_TIN file was delineated using the “Delineate TIN Data Area (3D Analyst)” tool by specifying the 1938_2004_LooeKey_SeafloorStability_TIN file as the “Input TIN”, a “Maximum Edge Length” of 900 (Yates and others, 2017b) and the “Method” set to ALL. The delineated 1938_2004_LooeKey_SeafloorStability_TIN was then clipped to the extent of the 1938 and 2004 data using the “Edit TIN (3D Analyst)” tool with the following parameters: “Input TIN”: 1938_2004_LooeKey_SeafloorStability_TIN file; “Input Features Class”: 1938-2004 geometric intersection footprint; “Height Field”: None; “Tag Field”: None; and “Type”: Hard clip. This step was required to remove unwanted triangles that spanned data gaps in the original data used to generate the 1938_2004_LooeKey_SeafloorStability_Points shapefile. For information on how to generate a geometric intersection between the 1938 and 2004 data, see Yates and others (2017b). Process_Date: 2020 Process_Step: Process_Description: Step 3: The 1938_2004_LooeKey_SeafloorStability_TIN file was classified into five stability categories using a defined stability threshold to identify areas of stability and instability. The stability threshold is the total root mean square error (RMSE) calculated for the 1938-2004 Looe Key elevation-change points using the vertical uncertainty of the 1938 historical hydrographic survey and 2004 DEM. A total RMSE of 0.29 m was calculated and rounded down to create a stability threshold of 0.25 m that is consistent with corresponding datasets. See Yates and others (2017b) for methods on calculating the RMSE. Based on the specified stability threshold of 0.25 m, the following five stability categories were identified: Stable: 0.0 m to ±0.24 m or 0.0 m to ±0.49 m; Moderately stable: ±0.25 m to ±0.49 m; Moderately unstable: ±0.50 m to ±0.74 m; Mostly unstable: ±0.75 m to ±0.99 m; and Unstable: ±1.00 m to Max/Min elevation change. Category boundaries use the pattern of “lower bound < or = x < upper bound” to avoid inclusion of individual elevation-change values in multiple categories. The categories were assigned based on the absolute value of the elevation-change values. For example, values within ±0.24 m of change were classified as Stable. Process_Date: 2020 Process_Step: Process_Description: Step 4: The 1938_2004_LooeKey_SeafloorStability_TIN file was opened in ArcMap and the “Layer Properties” window was opened by double clicking the TIN in the “Table of Contents”. Within the “Symbology” tab, “Show: Elevation” was enabled, and “Classification Classes” was set to 10. To specify the bin values, “Classify” was selected within the “Classification” window, and the following “Break Values” were used to classify and bin the elevation-change values into ten classes: -0.994999 (class1); -0.744999 (class 2); -0.494999 (class 3); -0.244999 (class 4); 0 (class 5); 0.244999 (class 6); 0.494999 (class 7); 0.744999 (class 8); 0.994999 (class 9); and maximum positive elevation-change value (class 10). The “Break Values” were based on the 0.25 m stability threshold, with each class increasing in increments of 0.24 m up to ±1 m of change. Classes 4, 5 and 6 represent the stable elevation-change values with no change detected (Stable), classes 1 and 10 represent the unstable elevation-change values with change greater than ±1 m (Unstable), and the remaining classes represent the elevation-change values in between (Moderately stable through Mostly unstable). Process_Date: 2020 Process_Step: Process_Description: Step 5: The color symbology of the classes listed in the “Table of Contents” were changed to represent each stability category. A color gradient of red, gray, and blue shades was applied to the binned TIN to distinguish the stability level of each elevation-change value and distinguish areas of erosion and accretion. Both positive and negative elevation-change values that fell within the Stable category were colored gray. However, red and blue shades were applied to elevation-change values that fell within categories Moderately stable through Unstable to distinguish areas of erosion and accretion. Blue shades were applied to elevation-change values with positive elevation change (accretion) and red shades were applied to elevation-change values with negative elevation change (erosion). Lighter shades indicate the smallest amount of change while darker shades indicate the largest amount of change. Process_Date: 2020 Process_Step: Process_Description: Step 6: Additionally, the 1938-2004 Looe Key elevation-change points were classified into the five stability categories. The process was similar to the methods described in steps 3-5; however, the “Break Values” were defined differently because the method for binning points is different than delineating break points for a TIN in ArcMap. The 1938_2004_LooeKey_SeafloorStability_Points shapefile was opened in ArcMap and the “Layer Properties” window was opened by double clicking the points in the “Table of Contents”. Within the “Symbology” tab, “Show: Quantities” was expanded, “Graduated Colors” was selected, “Value” was set to the attribute containing the elevation-change values (Diff_m) and “Classification Classes” was set to 10. The maximum sample size was reached. To change the sample size, “Classify” was selected within the “Classification” window, and the “Data Sampling” window was opened by selecting “Sampling”. Within the “Data Sampling” window, “Maximum Sample Size” was set to the total number of points, 1,687. The following “Break Values” were used to classify and bin the Diff_m values into ten classes: -0.995 (class 1); -0.745 (class 2); -0.495 (class 3); -0.245 (class 4); 0 (class 5); 0.244999 (class 6); 0.494999 (class 7); 0.744999 (class 8); 0.994999 (class 9); and max positive Diff_m value (class 10). The remaining steps to change the color symbology are the same as described in step 5. Process_Date: 2020 Process_Step: Process_Description: Step 7: The above process steps were repeated four times using different stability categories to represent a total of five different resolutions of elevation-change stability maps. The same color scheme was used for each resolution map. The above stability categories and “Break Values” described in Steps 3-6 represent the highest resolution map, 5th order. The remaining four resolutions of maps (1st through 4th order) required different “Break Values” and stability category ranges. The specific parameters for each resolution map are described in steps 8 through 11. Process_Date: 2020 Process_Step: Process_Description: Step 8: The 4th order resolution map was generated for the 1938_2004_LooeKey_SeafloorStability_TIN file using the following eight “Break Values”: -0.744999, -0.494999, -0.244999, 0, 0.244999, 0.494999, 0.744999, and max positive elevation-change value. The following eight “Break Values” were used for the 1938_2004_LooeKey_SeafloorStability_Points shapefile: -0.745, -0.495, -0.245, 0, 0.244999, 0.494999, 0.744999, and max Diff_m value. The four associated stability categories for both are as follows: Stable: 0.0 m to ±0.24 m, Moderately stable: ±0.25 m to ±0.49 m, Moderately unstable: ±0.50 m to ±0.74 m, Unstable: ±0.75 m to Max/Min elevation change. The 4th order resolution maps combine the Mostly unstable values into the Unstable category. Process_Date: 2020 Process_Step: Process_Description: Step 9: The 3rd order resolution map was generated for the 1938_2004_LooeKey_SeafloorStability_TIN file using the following six “Break Values”: -0.494999, -0.244999, 0, 0.244999, 0.494999, and max positive elevation-change value. The following six “Break Values” were used for the 1938_2004_LooeKey_SeafloorStability_Points shapefile: -0.495, -0.245, 0, 0.244999, 0.494999, and max positive Diff_m value. The three associated stability categories for both are as follows: Stable: 0.0 m to ±0.24 m, Moderately stable: ±0.25 m to ±0.49 m, Unstable: ±0.50 m to Max/Min elevation change. The 3rd order resolution maps combine the Moderately unstable and Mostly unstable values into the Unstable category. Process_Date: 2020 Process_Step: Process_Description: Step 10: The 2nd order resolution map was generated for the 1938_2004_LooeKey_SeafloorStability_TIN file using the following three “Break Values”: -0.494999, 0.494999, and max positive elevation-change value. The following three “Break Values” were used for the 1938_2004_LooeKey_SeafloorStability_Points shapefile: -0.495, 0.494999, and max positive Diff_m value. The two associated stability categories for both are as follows: Stable: 0.0 m to ±0.49 m and Unstable: ±0.50 m to Max/Min elevation change. The 2nd order resolution maps combine the Moderately stable values into the Stable category, and the Moderately unstable and Mostly unstable values into the Unstable category. Process_Date: 2020 Process_Step: Process_Description: Step 11: The 1st order resolution map was generated using the same “Break Values” and stability category ranges as the 2nd order resolution map. However, both positive and negative values that fell within the Unstable category were colored dark red regardless of being negative or positive to depict only stable and unstable areas regardless of gain or loss in elevation. Process_Date: 2020 Process_Step: Process_Description: Step 12: The USGS SPCMSC analyzed seafloor elevation change and stability throughout the Florida Reef Tract (FRT) at potential coral reef restoration locations provided by partnering stakeholders. Ten reef locations of interest throughout the FRT were identified by NOAA Florida Keys National Marine Sanctuary, one reef of which (Looe Key reef and research only area) falls within the bounds of the 1938-2004 Looe Key data extent. Additionally, seafloor stability data were requested from Mote Marine Laboratory for 50 authorized coral outplant sites (Special Activity License: SAL-18-1724-SCRP) and five potential coral outplant sites along the FRT. Seven of the 50 authorized outplant sites fell within the bounds of the 1938-2004 Looe Key data extent. Process_Date: 2020 Process_Step: Process_Description: Step 13: Boundaries for the coral reefs of interest were downloaded as a Keyhole Markup Language Zipped file (KMZ) from the NOAA Florida Keys National Marine Sanctuary webpage (https://floridakeys.noaa.gov/fknms_map/welcome.html; last accessed: 27 November 2019). Using ArcMap, the KMZ file was converted to a single merged polygon shapefile, creating the NOAA_CoralReef_LocationsOfInterest shapefile. The polygons encompassing the ‘Looe Key reef and research only area’ were included in this file. A point shapefile containing the seven authorized outplant sites (MotesAuthorized_OutplantSites shapefile) was created using the coordinate locations from Mote Marine Laboratory. Mote Marine Laboratory provided the USGS SPCMSC with the latitude, longitude, and site description of each outplant site. Horizontal coordinates are referenced to the UTM NAD83 (NSRS2007) National Readjustment and vertical coordinates are referenced to the NAVD88, GEOID12B geoid model. Process_Date: 2020 Process_Step: Process_Description: Step 14: Elevation-change information was extracted from the 1938_2004_LooeKey_SeafloorStability_TIN file at the location of the MotesAuthorized_OutplantSites shapefile using the “Add Surface Information (3D Analyst)” tool by specifying the MotesAuthorized_OutplantSites shapefile as the “Input Feature Class”, the 1938_2004_LooeKey_SeafloorStability_TIN file as the “Input Surface”, Z as the “Output Property”, LINEAR as the “Method”, and “Sampling Distance” and “Z Factor” left blank. A single elevation-change value was extracted from the TIN at the location of each point that fell within the bounds of the 1938_2004_LooeKey_SeafloorStability_TIN file. Process_Date: 2020 Process_Step: Process_Description: Step 15: The average elevation change and standard deviation was calculated from the 1938_2004_LooeKey_SeafloorStability_Points shapefile at the location of the ‘Looe Key reef and research only area’ polygons using the “Statistics” tool in ArcMap. When calculating average elevation change and standard deviation for locations defined by bounding box coordinates, the elevation-change points were used. Process_Date: 2020 Process_Step: Process_Description: Step 16: Using Microsoft Excel 2016, all statistics were entered into a table and color coded based on the defined stability colors for each map resolution. Additionally, average elevation changes and standard deviations calculated by the USGS SPCMSC for each habitat found within the 1938-2004 elevation-change points data extent were included in the table. No-data values are indicated by -99. For information on how to calculate elevation-change statistics by habitat type, see Yates and others (2017b). Process_Date: 2020 Process_Step: Process_Description: Step 17: Map packages (.mpk) containing a map document and the data it contains were created for each resolution map. Each map document contains the MotesAuthorized_OutplantSites shapefile, NOAA_CoralReef_LocationsOfInterest shapefile, habitat map, and the binned and color coded 1938_2004_LooeKey_SeafloorStability_Points shapefile and 1938_2004_LooeKey_SeafloorStability_TIN file. For users that have access to ArcMap, the map packages can be downloaded and opened to display the coral restoration locations, habitat types, and binned points and TIN for each resolution. The individual contents of the map packages are also provided in this data release, including layer files that store the symbology information for each resolution of the seafloor stability points and TIN. The layer files can be applied to the stability points or TIN in ArcMap within the “Symbology” tab of the “Layer Properties” window.
