The Arctic Ocean, located mostly in the Arctic north polar region, is the smallest and the shallowest. Even though the International Hydrographic Organization (IHO) recognizes it as an ocean, oceanographers may call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it as one of the mediterranean seas of the Atlantic Ocean.

Medieval European and Arabic literature often spoke of the Seven Seas. Which seven seas are intended depends on the context. The "Seven Seas" was a commonplace phrase in many ancient literatures before it was taken up by the Greeks and Romans; it appears in a translation of one of Enheduanna's hymns to Inanna (Hymn 8), written about 2300 BC in Sumer (Meador 2001). The number seven has ancient magic of its own in many traditions, informing many groupings of seven. "Seven" as an indefinite number remains for a long time synonymous with "several", as in the Greek Seven Seas. In Greek and Western culture, the "seven" seas were arbitrary and changed over time, varying depending upon the part of the world and the period of time. However, they were usually seven out of the following list of nine bodies of water:

•Adriatic Sea
A large body of water on the west side of the Mediterranean Sea separating the Apennine peninsula from the Balkan peninsula, and the system of the Apennine Mountains from that of the Dinaric Alps and adjacent ranges. The western coast is Italian, while the eastern coast runs along Italy, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, and Albania.

It extends northwest from 40° to 45° 45' N., with an extreme length of about 770 km (415 nm, 480 mi). It has a mean breadth of about 160 km (85 nm, 100 mi), although the Strait of Otranto, through which it connects at the south with the Ionian Sea, is only 45-55 nautical miles wide (85-100 km). Moreover, the chain of islands which fringes the northern part of the eastern shore reduces the extreme breadth of open sea in this part to 145 km (78 nm, 90 mi). Its total surface area is about 60,000 square miles (160,000 km²).
The northern part of the sea is very shallow, and between the southern promontories of Istria and Rimini the depth rarely exceeds 46 m (25 fathoms). Between Å ibenik and Ortona a well-marked depression occurs, a considerable area of which exceeds 180 m (100 fathoms) in depth.

From a point between Korčula and the north shore of the spur of Monte Gargano there is a ridge giving shallower water, and a broken chain of a few islets extends across the sea.
The deepest part of the sea lies east of Monte Gargano, south of Dubrovnik, and west of Durrës where a large basin gives depths of 900 m (500 fathoms) and upwards, and a small area in the south of this basin falls below 1,460 m (800 fathoms). The mean depth of the sea is estimated at 240 m (133 fathoms).

•Aegean Sea
Greek: Αιγαίο Πέλαγος, Aeyéo Pélagos; Turkish: Ege Denizi) is a sea arm of the Mediterranean Sea located between the southern Balkan and Anatolian peninsulas, i.e., between the mainlands of Greece and Turkey respectively. In the north, it is connected to the Marmara Sea and Black Sea by the Dardanelles and Bosporus. The Aegean Islands are within the sea and some bound it on its southern periphery, including Crete and Rhodes. The sea was traditionally known as the Archipelago (Greek: Αρхιπέλαγος), the general sense of which has since changed to refer to the Aegean Islands and, generally, to any island group because the Aegean Sea is remarkable for its large number of islands.

It covers about 214 000 square kilometres in area, and measures about 610 kilometres longitudinally and 300 kilometres latitudinally. The sea's maximum depth is 3 543 metres, east of Crete. The Aegean Islands are found within its waters, with the following islands delimiting the sea on the south (generally from west to east): Kythera, Antikythera, Crete, Karpathos, and Rhodes.

•Arabian Sea
(Arabic: بحر العرب; transliterated: Bahr al-'Arab, Latin: Mare Erythraeum) is a region of the Indian Ocean bounded on the east by India, on the north by Pakistan and part of the southern Persian littoral, on the west by Arabian Peninsula, on the south, approximately, by a line between Cape Guardafui, the north-east point of Somalia, Socotra and Kanyakumari (Cape Comorin) in India. It was known as the Sindhu Sagar to Indians in the Vedic period of their history.

It has two important branches — the Gulf of Aden in the southwest, connecting with the Red Sea through the strait of Bab-el-Mandeb; and the Gulf of Oman to the northwest, connecting with the Persian Gulf. Besides these larger ramifications, there are the gulfs of Cambay and Kutch on the Indian coast. Its islands are few, the chief being Socotra, off the African, and the Laccadives, off the Indian coast.

Ocean trade routes have crossed the Arabian Sea since ancient times, linking the Near East with East Africa, India, Southeast Asia, and China. Historically, sailors in a type of ship called a dhow used the seasonal Monsoon winds to cross the sea. The sea forms part of the chief shipping route between Europe and India via the Suez Canal, which links the Red Sea with the Mediterranean Sea.

The maximum width of the Arabian Sea is approximately 2,400 km, and its maximum depth is 4,652 metres, in the Arabian Basin approximately at the same latitude as the southernmost tip of India. The Indus River, also known as the Sindhu river, is the largest river flowing directly into this sea; others include the Narmada, Tapti, Mahi, and the numerous rivers of Kerala in India. The Arabian Sea coast of central India is known as the Konkan Coast, and that of southern India is known as the Malabar Coast.

The countries with coastlines on the Arabian Sea are India, Iran, Oman, Pakistan, Srilanka, Yemen, Somalia and the Maldives.

Cities on the coast include Mumbai (Bombay), Surat, Mangalore, and Kochi (often described as the Queen of the Arabian Sea[1]) in India, Karachi and Gwadar in Pakistan, and Aden in Yemen. Famous beaches on the coast include
•beaches of Karachi, Main Khye
•the beaches of Goa
•Juhu Beach, Mumbai
•Kovalam beach in Kerala

•Black Sea
is an inland sea between southeastern Europe and Anatolia that is actually a distant arm of the Atlantic Ocean by way of the Mediterranean Sea. It is connected to the Mediterranean by the Bosporus and the Sea of Marmara, and to the Sea of Azov by the Strait of Kerch.

There is a net inflow of seawater through the Bosporus, 200 km³ per year. There is an inflow of freshwater from the surrounding areas, especially central and middle-eastern Europe, totalling 320 km³ per year. The most important river entering the Black Sea is the Danube. The Black Sea has an area of 422,000 km² and a maximum depth of 2210 m.

Countries bordering on the Black Sea are Turkey, Bulgaria, Romania, Ukraine, Russia, and Georgia. The Crimean peninsula is a Ukrainian autonomous republic. Important cities along the coast include: Istanbul, Burgas, Varna, Constanţa, Yalta, Odessa, Sevastopol, Kerch, Novorossiysk, Sochi, Sukhumi, Poti, Batumi, Trabzon, Samsun and Zonguldak.

The Black Sea forms an enclosed basin, located between south-eastern Europe and Asia Minor. The basin was formed during the Miocene orogenies which uplifted the mountain ranges and divided the ancient Tethys Ocean into several brackish basins, including the Sarmatic Sea. The Caspian, Azov, Aral and Black Seas are the remnants of this evaporated basin.

The Bulgarian coastline of the Black Sea has only a few small, barren islands.

The basin is divided into two sub-basins by a convexity extending south from the Crimean peninsula. The north-west of the basin is characterized by a relatively large shelf up to 190 km wide, which has a relatively shallow apron with gradients between 1:40 and 1:1000. The southern edge around Turkey and the eastern edge around Georgia however, are typified by a shelf that rarely exceeds 20km in width and an apron that is typically 1:40 gradient with numerous submarine canyons and channel extensions. The Euxine abyssal plain in the centre of the Black Sea reaches a maximum depth of 2,206m just south of Yalta on the Crimean peninsula. The basin is connected to the Mediterranean Sea via the Turkish Straits System (TSS) in the south-west, which includes the Bosporus and Dardanelles straits and the Sea of Marmara. The Black Sea is connected to the Sea of Azov in the north-east via the Kerch straits.

•Caspian Sea
is the largest lake on Earth by both area and volume, with a surface area of 371,000 square kilometres (143,244 mi²) and a volume of 78,200 cubic kilometres (18,761 mi³).It is a landlocked endorheic body of water and lies between Asia and Europe. It has a maximum depth of about 1025 meters (3,363 ft). It is called a sea because when the Romans arrived for their first time, they tasted the water and found it to be salty. The Caspian Sea is bordered by Russia (Dagestan, Kalmykia, Astrakhan Oblast), Azerbaijan, Iran (Guilan, Mazandaran and Golestan provinces), Turkmenistan (Balkan Province), and Kazakhstan, with the central Asian steppes to the north and east. On its eastern Turkmen shore is a large embayment, the Garabogazköl.

The sea is connected to the Sea of Azov by the Manych Canal and the Volga-Don Canal.

It has a salinity of approximately 1.2%, about a third the salinity of sea water. Caspian Sea has characteristics common to both seas and lakes. It is often listed as the world's largest lake, though it is not a freshwater lake.

•Indian Ocean
The Indian Ocean is the third largest body of water in the world, covering about 20% of the Earth's water surface. It is bounded on the north by Southern Asia (including the Indian subcontinent, hence its name); on the west by the Arabian Peninsula and Africa; on the east by the Malay Peninsula, the Sunda Islands, and Australia; and on the south by the Southern Ocean. It is separated from the Atlantic Ocean by the 20° east meridian running south from Cape Agulhas,[1] and from the Pacific by the 147° east meridian. The northernmost extent of the Indian Ocean is approximately 30° north latitude in the Persian Gulf. This ocean is nearly 10,000 kilometers (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometers (28,400,000 mi²), including the Red Sea and the Persian Gulf.
The ocean's volume is estimated to be 292,131,000 cubic kilometers (70,086,000 mi3). Small islands dot the continental rims. Island nations within the ocean are Madagascar (formerly Malagasy Republic), the world's fourth largest island; Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka. Indonesia borders it. The ocean's importance as a transit route between Asia and Africa has made it a scene of conflict. Because of its size, however, no nation had successfully dominated most of it until the early 1800s when Britain controlled much of the surrounding land. After World War II, the ocean has been dominated by India and Australia.

•Mediterranean Sea
is a sea of the Atlantic Ocean almost completely enclosed by land: on the north by Europe, on the south by Africa, and on the east by Asia. It covers an approximate area of 2.5 million km² (965 000 mi²), but its connection to the Atlantic (the Strait of Gibraltar) is only 14 km (9 mi) wide. In oceanography, it is sometimes called the Eurafrican Mediterranean Sea or the European Mediterranean Sea, to distinguish it from mediterranean seas elsewhere.
It was a superhighway of transport in ancient times, allowing for trade and cultural exchange between emergent peoples of the region — the Mesopotamian, Egyptian, Semitic, Persian, Phoenician, Carthaginian, Greek, Roman and Turkish cultures. The history of the Mediterranean is important in understanding the origin and development of Western Civilization.

The Mediterranean Sea has an average depth of 1,500 m and the deepest recorded point is 5267 meters (about 3.27 miles) in the Calypso Deep in the Ionian Sea. The coastline extends for 46,000 km. A shallow submarine ridge (the Strait of Sicily) between the island of Sicily and the coast of Tunisia divides the sea in two main subregions (which in turn are divided into subdivisions), the Western Mediterranean and the Eastern Mediterranean. The Western Mediterranean covers an area of about 0.85 million km² and the Eastern Mediterranean about 1.65 million km².

•Persian Gulf
Persian: خليج فارس khalīj-e-Fārs; in Arabic: الخليج الفارسي al-khalīj al-fārisī), in the Southwest Asian region, is an extension of the Gulf of Oman located between Iran (Persia) and the Arabian Peninsula.
The Persian Gulf was the focus of the Iraq-Iran War that lasted from 1980 to 1988, with each side attacking the other's oil tankers. In 1991, the Persian Gulf again was the background for what was called the "Persian Gulf War" or "The Gulf War" when Iraq invaded Kuwait and was subsequently pushed back, despite the fact that this conflict was primarily a land conflict.
The natural environment of the Persian Gulf is very rich with good fishing grounds, extensive coral reefs, and abundant pearl oysters, but its ecology has become increasingly under pressure from the heavy industrialisation and in particular the repeated major petroleum spillages associated with recent wars fought in the region.

•Red Sea
is an inlet of the Indian Ocean between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb sound and the Gulf of Aden. In the north are the Sinai Peninsula, the Gulf of Aqaba or the Gulf of Eilat and the Gulf of Suez (leading to the Suez Canal).
Occupying a part of the Great Rift Valley, the Red Sea has a surface area of roughly 174,000 square miles (450,000 km²): being roughly 1,200 miles (1,900 km) long and, at its widest point, over 190 miles (300 km) wide. It has a maximum depth of 8,200 feet (2,500 m) in the central median trench and an average depth of 1,640 feet (500 m), but there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species and 200 soft and hard corals and is the world's most northern tropical sea.
The Red Sea is regarded as one of the most saline water bodies in the world that is governed by the effects of the water circulation pattern, resulting from evaporation and wind stress in the Red Sea. Salinity ranges between 36 and 38 ‰.


Not all Roman uses of septem maria (Latin) would strike a responsive chord today. The navigable network in the mouths of the Po river discharge into saltmarshes on the Adriatic shore; these were locally called the "Seven Seas" in ancient Roman times. Pliny the Elder, a Roman author and fleet commander, wrote about these lagoons, separated from the open sea by sandbanks:

"All those rivers and trenches were first made by the Etruscans, thus discharging the flow of the river across the marshes of the Atriani called the Seven Seas, with the famous harbor of the Etruscan town of Atria which formerly gave the name of Atriatic to the sea now called the Adriatic." (Historia Naturalis, III 120[3].

Thus today at the Septem Maria Museum we can trace water civilization from protohistory until today. This early cultural root may be visited at Adria in Rovigo, the modern Atria

The 17th century churman and scholar John Lightfoot mentions a very different set of seas in his Commentary on the New Testament. A chapter titled The Seven Seas according to the Talmudists, and the four Rivers compassing the Land includes the "Great Sea" (now called the Mediterranean Sea), the "Sea of Tiberias" (Sea of Galilee), the "Sea of Sodom" (Dead Sea), the "Lake of Samocho", and the "Sibbichaean".

Among mariners, starting from Colonial times, "sailing the Seven Seas" meant one had been to the seven small seas throughout the Dutch East Indies. In effect it meant they had sailed to, and returned from the other side of the world.

Finally, some modern geographical classification schemes count seven oceans in the world:
•North Pacific Ocean
•South Pacific Ocean
•North Atlantic Ocean
•South Atlantic Ocean
•Indian Ocean
•Southern Ocean
•Arctic Ocean
