What does this data set describe?
    Title:
    pr_eez_region - United States Exclusive Economic Zone Regional Boundary
    Abstract:
    Exclusive Economic Zone (EEZ) and Maritime Boundaries; Notice of Limits By Presidential Proclamation No. 5030 made on March 10, 1983, the United States established an exclusive economic zone, the outer limit of which is a line drawn in such a manner that each point on it is 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. The Government of the United States of America has been, is, and will be, engaged in consultations and negotiations with governments of neighboring countries concerning the delimitation of areas subject to the respective jurisdiction of the United States and of these countries. The limits of the exclusive economic zone of the United States as set forth below are intended to be without prejudice to any negotiations with these countries or to any positions which may have been or may be adopted respecting the limits of maritime jurisdiction in such areas. Further, the limits of the exclusive economic zone set forth below are without prejudice to the outer limit of the continental shelf of the United States where that shelf extends beyond 200 nautical miles from the baseline in accordance with international law.
