Marine protected areas

The location of protected areas in IUCN categories I-VI that are entirely or in part marine, with map symbols graded according to protected area size (including any land present).
Note: for presentation purposes it has been necessary to use symbols that in most cases at this map scale greatly exceed the size of the protected area represented, giving the impression that much more of the world's coastal waters are protected than is in fact the case.
