The 9 nautical mile line was derived by creating a buffer from the U.S. baseline points and closing lines.
NOAA National Ocean Service (NOS) Baseline Committee Representative provided updated U.S. baseline points and closing lines to GIS Coordinator in October 2017. Points and lines were projected to an equidistant projection and buffered out to 9 nautical miles. NOS uses Caris LOTS software to buffer the baseline to create the U.S. Territorial Sea boundary. They have created and compared unprojected data (WGS-84 datum) using Esri software and found it was sufficient. Therefore, a 9 nautical mile buffer was created using the baseline data as received (in WGS-84 datum) from NOS.

The 9 nautical mile buffers created seaward from the baseline points and closing lines were merged with the most seaward boundary taking precedence to create a single 9 nautical mile boundary line for the entire Gulf of Mexico States.

As a quality check, the same baseline points and closing lines were buffered to 12 nautical miles. The output was compared to the U.S. Territorial Sea boundary downloaded from MarineCadastre.gov (MMC). The currentness of the MMC data is 2013. Most data was within 2 meters difference, with some areas at most 10 meters different. These differences may be related to the difference between Caris LOTS and Esri software to create the boundary, as the baseline points supplied for this project were current.
