Abstract:
To characterize coastal change, historical maps and complementary records were compiled including: topographic sheets (T-sheets), hydrographic sheets (H-sheets, smooth sheets), shorelines, and bathymetric soundings surrounding the Mississippi (MS) barrier islands over several time periods (1916-1920, 2008-2009 and 2016). One goal of this work was to create a time-series of bathymetric change maps around the islands. Datasets include 1916 through 1920 soundings collected by the United States Coast and Geodetic Survey as downloaded H-sheets and some digitized soundings from the National Oceanic and Atmospheric Administration (NOAA), 2008 to 2009 soundings collected by the United States Geological Survey St. Petersburg and Woods Hole Coastal and Marine Science Center (USGS SPCMSC and WHCMSC, respectively), and 2016 soundings collected by the USGS SPCMSC in the nearshore environment of Ship, Horn, and Petit Bois Islands. This USGS data release includes three digital elevation models (DEMs) for 1916 to 1920, 2008 to 2009, and 2016; however, this metadata file pertains only to the 1916 to 1920 DEM (1916_1920_MS_NAD83NAVD88g12B_50m.tif). This work was completed in cooperation with the United States Army Corps of Engineers (Mobile, Alabama) and the National Park Service as part of the Mississippi Coastal Improvements Program (MsCIP).
Purpose:
The purpose of this effort was to create bathymetric grids and bathymetric change maps around the MS barrier islands to broadly characterize subaqueous morphologic change both spatially and temporally.
Supplemental_Information:
Elevation XYZ data used to create the 1916 to 1920 and 2008 to 2009 DEMs are included in this USGS data release; 2016 XYZ data can be downloaded from DeWitt and others, 2017. The 1916 to 2009 elevation (z) values were adjusted to account for sea-level rise, using the NOAA tide gauge at Pensacola, FL. For further information on XYZ processing, refer to the accompanying elevation point metadata and Dewitt and others (2017). Within ArcGIS 10.4.1, XYZ soundings for 1916-1920, 2008-2009, and 2016 were used to create Triangular Irregular Network (TIN) surfaces, individual TIN surfaces were later utilized to create a time-series of 50-m bathymetric rasters. All spatial files provided in this data release are referenced to the Universal Transverse Mercator (UTM) North American Datum (NAD83) horizontal datum and North American Vertical Datum of 1988 (NAVD88) GEOID12B.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of this DEM is directly linked to the accuracy of the XYZ point data on which it is based (Buster and Morton, 2011). These datasets were from multiple research cruises spanning over four years (1916-1920) and were collected following variable methodologies; therefore, they are not internally consistent. Additionally, vertical datums associated with XYZ data have been recalculated (using NOAA's Vdatum software and a NOAA tide gauge at Pensacola, FL) to allow for time series comparisons and this process introduces uncertainties into the data. Uncertainties are also introduced in interpolating DEM surfaces within Esri ArcGIS. The DEMs have not been independently verified for accuracy. Please see Buster and Morton, (2011) and Dewitt and others (2012) for full accuracy and error information.
Logical_Consistency_Report:
This dataset includes the post-processed bathymetric data (XYZ) presented as an interpolated DEM. The source data for the DEM was collected during multiple bathymetry surveys from 1916-1920 near Ship, Horn, and Petit Bois islands in Mississippi. All spatial files provided in this data release are referenced in NAD83 NAVD88g12B UTM 16N, meters.
Completeness_Report:
The source data is historical and; therefore, not complete in its coverage. The source data was used to create DEM surfaces that best represent the historical soundings, using best practice methods to keep the data as accurate as possible. See above accuracy report information for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
No formal positional accuracy tests were conducted; however, Buster and Morton (2011) estimate horizontal accuracy values less than 20 and 29 meters for historic T-sheets and H-sheets that were used to create the original 1916-1920 XYZ bathymetric dataset. Additional uncertainty was introduced throughout DEM interpoloation steps outlined below. These additional sources of error include 1) vertical datum conversion using NOAA's Vdatum software and, 2) creation of a triangulated Irregular Network (TIN) and interpolation of the DEM raster, with 50-m cell size and using nearest neighbor interpolation, within ArcGIS (version 10.4.1).
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Likely due to the age of the data and variable survey collection methods, no formal vertical accuracy tests were conducted in association with the original publication of the 1916-1920 bathymetric dataset (Buster and Morton, 2011). Subsequent data processing steps, specifically converting the vertical datum of the XYZ data and interpolating DEM surfaces within Esri ArcGIS, are additional sources of uncertainty that have not been fully assessed.

Process_Description:
Using Esri ArcGIS 10.4.1, XYZ bathymetric point data for the 1916-1920 time period (1916_1920_MSAL_NAD83NAVD88g12B_XYZ.zip,) were used to create a TIN surface using the 'Create TIN' tool within the 3D Analyst toolbox. The subaerial extent of Ship, Horn, Petit Bois, and Dauphin Island were assigned the regional operational mean high water (MHW) value of 0.23 m (Weber and others, 2005) by soft clipping the TIN to coincident island shoreline shapefile (1917_shoreline_MSAL.zip within Buster and Morton [2011]) with elevation values of 0.23 m. The TIN was also clipped to the outer spatial extent of reliable data coverage of the XYZ dataset.

Process_Description:
Using Esri ArcGIS 10.4.1, the TIN dataset for 1916-1920 was used to create gridded raster surfaces using the 'TIN to Raster' tool within the 3D Analyst toolbox. The raster was interpolated using the nearest neighbor algorithm with a 50 m cell size and the processing extent was a common 50-m snap raster (MS_2017_snapraster50m.tif within this data release) used for the interpolation to ensure the pixel cell center locations of the resulting raster matched other DEM rasters in this data release, allowing for direct comparisons. The 1916-1920 DEM was also clipped to an overall spatial coverage more comparable to the 2008-2009 and 2016 datasets.
