Service Description: Tile Layer used in the A Century of Change in Grand Bay, Mississippi and Alabama geonarrative.

Data depicts single-beam bathymetry data utilizing tile layers hosted on ArcGIS Online. Bathymetry data were downloaded from the USGS data release web pages (see data sources below). The downloaded files were opened in ArcGIS Pro 2.8, re-projected into WGS84 to match ArcGIS Online basemap projections, the depth value range was set to 0 to 3.81, and the symbology was set to a blue color range. Darker blue values indicate a deeper depth, and lighter blue values indicate a shallower depth. Each bathymetry dataset was shared to ArcGIS Online as a hosted tile layer and accompanying service definition. This tile layer is to be used in the Grand Bay Bathymetry Web Map.
