Southern Ocean
A large body of recent oceanographic research has
shown that the Antarctic Circumpolar Current (ACC), an ocean current
that flows from west to east around Antarctica, plays a crucial role
in global ocean circulation. The region where the cold waters of the
ACC meet and mingle with the warmer waters of the north defines a
distinct border - the Antarctic Convergence - which fluctuates with
the seasons, but which encompasses a discrete body of water and a
unique ecologic region. The Convergence concentrates nutrients,
which promotes marine plant life, and which in turn allows for a
greater abundance of animal life. In the spring of 2000, the
International Hydrographic Organization decided to delimit the
waters within the Convergence as a fifth world ocean - the Southern
Ocean - by combining the southern portions of the Atlantic Ocean,
Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the
coast of Antarctica north to 60 degrees south latitude, which
coincides with the Antarctic Treaty Limit and which approximates the
extent of the Antarctic Convergence. As such, the Southern Ocean is
now the fourth largest of the world's five oceans (after the Pacific
Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic
Ocean). It should be noted that inclusion of the Southern Ocean does
not imply recognition of this feature as one of the world's primary
oceans by the US Government.

Spain
Spain's powerful world empire of the 16th and 17th centuries
ultimately yielded command of the seas to England. Subsequent
failure to embrace the mercantile and industrial revolutions caused
the country to fall behind Britain, France, and Germany in economic
and political power. Spain remained neutral in World Wars I and II,
but suffered through a devastating civil war (1936-39). A peaceful
transition to democracy following the death of dictator Francisco
FRANCO in 1975, and rapid economic modernization (Spain joined the
EU in 1986), have given Spain one of the most dynamic economies in
Europe and made it a global champion of freedom. Continuing
challenges include Basque Fatherland and Liberty (ETA) terrorism and
relatively high unemployment.

Spratly Islands
The Spratly Islands consist of more than 100 small
islands or reefs. They are surrounded by rich fishing grounds and
potentially by gas and oil deposits. They are claimed in their
entirety by China, Taiwan, and Vietnam, while portions are claimed
by Malaysia and the Philippines. About 45 islands are occupied by
relatively small numbers of military forces from China, Malaysia,
the Philippines, Taiwan, and Vietnam. Brunei has established a
fishing zone that overlaps a southern reef, but has not made any
formal claim.

Sri Lanka
The Sinhalese arrived in Sri Lanka late in the 6th century
B.C., probably from northern India. Buddhism was introduced
beginning in about the mid-third century B.C., and a great
civilization developed at the cities of Anuradhapura (kingdom from
circa 200 B.C. to circa A.D. 1000) and Polonnaruwa (from about 1070
to 1200). In the 14th century, a south Indian dynasty seized power
in the north and established a Tamil kingdom. Occupied by the
Portuguese in the 16th century and by the Dutch in the 17th century,
the island was ceded to the British in 1796, became a crown colony
in 1802, and was united under British rule by 1815. As Ceylon, it
became independent in 1948; its name was changed to Sri Lanka in
1972. Tensions between the Sinhalese majority and Tamil separatists
erupted into war in 1983. Tens of thousands have died in the ethnic
conflict that continues to fester. After two decades of fighting,
the government and Liberation Tigers of Tamil Eelam (LTTE)
formalized a cease-fire in February 2002, with Norway brokering
peace negotiations. Violence between the LTTE and government forces
intensified in 2006, but neither side has formally withdrawn from
the cease-fire.

Sudan
Military regimes favoring Islamic-oriented governments have
dominated national politics since independence from the UK in 1956.
Sudan was embroiled in two prolonged civil wars during most of the
remainder of the 20th century. These conflicts were rooted in
northern economic, political, and social domination of largely
non-Muslim, non-Arab southern Sudanese. The first civil war ended in
1972, but broke out again in 1983. The second war and famine-related
effects resulted in more than 4 million people displaced and,
according to rebel estimates, more than 2 million deaths over a
period of two decades. Peace talks gained momentum in 2002-04 with
the signing of several accords; a final Naivasha peace treaty of
January 2005 granted the southern rebels autonomy for six years,
after which a referendum for independence is scheduled to be held. A
separate conflict that broke out in the western region of Darfur in
2003 has resulted in at least 200,000 deaths and nearly 2 million
displaced; as of late 2005, peacekeeping troops were struggling to
stabilize the situation. Sudan also has faced large refugee influxes
from neighboring countries, primarily Ethiopia and Chad, and armed
conflict, poor transport infrastructure, and lack of government
support have chronically obstructed the provision of humanitarian
assistance to affected populations.

Suriname
First explored by the Spaniards in the 16th century and
then settled by the English in the mid-17th century, Suriname became
a Dutch colony in 1667. With the abolition of slavery in 1863,
workers were brought in from India and Java. Independence from the
Netherlands was granted in 1975. Five years later the civilian
government was replaced by a military regime that soon declared a
socialist republic. It continued to exert control through a
succession of nominally civilian administrations until 1987, when
international pressure finally forced a democratic election. In
1990, the military overthrew the civilian leadership, but a
democratically elected government - a four-party New Front coalition
- returned to power in 1991 and has ruled since, expanding to eight
parties in 2005.

Svalbard
First discovered by the Norwegians in the 12th century, the
islands served as an international whaling base during the 17th and
18th centuries. Norway's sovereignty was recognized in 1920; five
years later it officially took over the territory.

Swaziland
Autonomy for the Swazis of southern Africa was guaranteed
by the British in the late 19th century; independence was granted in
1968. Student and labor unrest during the 1990s pressured King
Mswati III, the world's last absolute monarch, to grudgingly allow
political reform and greater democracy, although he has backslid on
these promises in recent years. Swaziland recently surpassed
Botswana as the country with the world's highest known rates of
HIV/AIDS infection.

Sweden
A military power during the 17th century, Sweden has not
participated in any war in almost two centuries. An armed neutrality
was preserved in both World Wars. Sweden's long-successful economic
formula of a capitalist system interlarded with substantial welfare
elements was challenged in the 1990s by high unemployment and in
2000-02 by the global economic downturn, but fiscal discipline over
the past several years has allowed the country to weather economic
vagaries. Sweden joined the EU in 1995, but the public rejected the
introduction of the euro in a 2003 referendum.

Switzerland
The Swiss Confederation was founded in 1291 as a
defensive alliance among three cantons. In succeeding years, other
localities joined the original three. The Swiss Confederation
secured its independence from the Holy Roman Empire in 1499.
Switzerland's sovereignty and neutrality have long been honored by
the major European powers, and the country was not involved in
either of the two World Wars. The political and economic integration
of Europe over the past half century, as well as Switzerland's role
in many UN and international organizations, has strengthened
Switzerland's ties with its neighbors. However, the country did not
officially become a UN member until 2002. Switzerland remains active
in many UN and international organizations, but retains a strong
commitment to neutrality.
