Two new data layers showing the Northeast’s robust network of ferry routes and terminals have been added to the Marine Transportation theme on the Northeast Ocean Data Portal. Both datasets are provided and maintained by the U.S. Department of Transportation’s Bureau of Transportation Statistics.

The Ferry Terminals map shows the origin and departure sites for ferries. The Ferry Routes map shows the approximate alignment of routes as determined through GPS and Automatic Identification System (AIS) data, as well existing government datasets from the Census Bureau, the U.S. Geological Survey, the National Oceanic and Atmospheric Association, and the U.S. Army Corps of Engineers. Users can click on any route for information about its operator, where it begins/ends, the time of year it runs, and more.

Related passenger vessel data available in the Marine Transportation theme includes a decade of interactive maps showing annual and monthly passenger vessel transit counts in the region. To view them, go to the Data Explorer, click on Commercial Traffic under Marine Transportation, and choose one of the Passenger Vessel Transit Counts options. Then go to the Active Layers tab to select monthly maps.
