Continental Shelf Boundary - Alaska NAD83

This data set contains Continental Shelf Boundaries (CSB) lines in ESRI shapefile format for the BOEM Alaska Region. The CSB defines the seaward limit of federally managed OCS lands. This CSB file only includes the lateral boundaries between the United States and Canada or Russia. That portion of the CSB defined by the 200 nautical mile line has not yet been calculated. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are NOT an OFFICIAL record for the exact CSB.
