Maritime Commerce Maps

About These Maps

The ocean is a critical resource for supporting domestic and international transportation and trade. This map shows navigation and marine operation areas based on nautical charts, information provided by the industry, and many other sources. It also includes potential natural and human hazards to shipping, and it provides vessel traffic patterns derived from the Automated Identification System (AIS).

We are working with BOEM, NOAA, the US Coast Guard, and the industry to improve these data sources, including identifying additional marine operation areas and deriving more information from AIS to better represent different types of vessel traffic and commerce.
