Before 1981, many islands which are now included under Atlantic Ocean Islands were also included as narrower terms of Atlantic Ocean. For several others, the change was made in 1985. Also see Antarctic Ocean for S portion.
This term is used for islands and island groups which could not easily be assigned to adjacent land areas. Before 1981, many of these islands and island groups were also narrower terms of Atlantic Ocean. Added to Thesaurus in 1981.
