In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Summary
This data release features two digitized historical shorelines for the Mississippi (MS) and Alabama (AL) coastline (Pascagoula, MS to Point aux Pins, AL) from 2010 and 2012. The shorelines were heads-up digitized using ArcMap 10.3.1 from 0.5-meter (m) resolution orthorectified aerial photos sourced from the City of Mobile, Alabama (http://maps.cityofmobile.org/gis/gisdata_order.aspx) and 1-m resolution orthorectified aerial photos sourced from the National Agriculture Imagery Program (https://gdg.sc.egov.usda.gov/). These shoreline datasets are suited for long-term shoreline and wetland analyses and physical change assessment.
