US Ocean

This layer is a component of Ocean.

This map contains polygons representing water outside the coastline of the United States. It fills in the gaps between the coastline in the Hydrographic Base Map for Terrain map service (txpub.usgs.gov/arcgis/rest/services/Mapping/HydroB...) and the coastline in the ESRI World Terrain Base map service (server.arcgisonline.com/ArcGIS/rest/services/World...) and creates a seamless transition between the two. The Ocean map layer was created from National Atlas One Million-Scale National Boundaries of the United States, version 2.
