began fighting over the area in 1988; the struggle escalated after
both countries attained independence from the Soviet Union in 1991.
By May 1994, when a cease-fire took hold, Armenian forces held not
only Nagorno-Karabakh but also a significant portion of Azerbaijan
proper. The economies of both sides have been hurt by their
inability to make substantial progress toward a peaceful resolution.
Turkey imposed an economic blockade on Armenia and closed the common
border because of the Armenian occupation of Nagorno-Karabakh and
surrounding areas.

Aruba
Discovered and claimed for Spain in 1499, Aruba was acquired
by the Dutch in 1636. The island's economy has been dominated by
three main industries. A 19th century gold rush was followed by
prosperity brought on by the opening in 1924 of an oil refinery. The
last decades of the 20th century saw a boom in the tourism industry.
Aruba seceded from the Netherlands Antilles in 1986 and became a
separate, autonomous member of the Kingdom of the Netherlands.
Movement toward full independence was halted at Aruba's request in
1990.

Ashmore and Cartier Islands
These uninhabited islands came under
Australian authority in 1931; formal administration began two years
later. Ashmore Reef supports a rich and diverse avian and marine
habitat; in 1983, it became a National Nature Reserve. Cartier
Island, a former bombing range, is now a marine reserve.

Atlantic Ocean
The Atlantic Ocean is the second largest of the
world's five oceans (after the Pacific Ocean, but larger than the
Indian Ocean, Southern Ocean, and Arctic Ocean). The Kiel Canal
(Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of
Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US)
are important strategic access waterways. The decision by the
International Hydrographic Organization in the spring of 2000 to
delimit a fifth world ocean, the Southern Ocean, removed the portion
of the Atlantic Ocean south of 60 degrees south latitude.

Australia
Aboriginal settlers arrived on the continent from
Southeast Asia about 40,000 years before the first Europeans began
exploration in the 17th century. No formal territorial claims were
made until 1770, when Capt. James COOK took possession in the name
of Great Britain. Six colonies were created in the late 18th and
19th centuries; they federated and became the Commonwealth
