The Adriatic Sea is an arm of the Mediterranean Sea which separates the Italian Peninsula from the Balkan peninsula, and the system of the Apennine Mountains from that of the Dinaric Alps and adjacent ranges. It extends from the Gulf of Venice southward to the Strait of Otranto, which links it to the Ionian Sea. It has an approximate length of 500 miles (800 km), an average width of 100 miles, and an area of 50,590 sq mi (131,050 sq km).

The sea's western coast runs the length of Italy, while the eastern coast forms the borders of Croatia, Bosnia and Herzegovina, Montenegro and Albania. A small slice of Slovenia also reaches to the Sea. Major rivers joining the Adriatic are the Reno, Po, Adige, Brenta, Piave, Soča/Isonzo, Zrmanja, Krka, Cetina, Neretva, Drin (Drini).


Name and etymology

Map of the Adriatic Sea

The name has existed since antiquity; in the Latin of the Romans (Ancient Latin) it was Mare Superum; in medieval Latin it was Mare Hadriaticum or Mare Adriaticum. The name, derived from the Etruscan colony of Adria (or Hadria), originally designated only the upper portion of the sea [1], but was gradually extended as the Syracusan colonies gained in importance. The word Adria probably derives from the Illyrian word adur meaning "water" or "sea". [2]

But even then the Adriatic in the narrower sense only extended as far as the Monte Gargano, the outer portion being called the Ionian Sea. The name was sometimes, however, inaccurately used to include the Gulf of Tarentum (the modern-day Gulf of Taranto), the Sea of Sicily, the Gulf of Corinth and even the sea between Crete and Malta[3].

The Adriatic Sea is situated largely between the eastern coast of Italy and the western coast of Croatia, both major tourist attractions. It was used by the ancient Romans to transport goods, including animals and slaves, to Ostia, the Roman port.

Extent and Bathymetry

The Adriatic extends northwest from 40° to 45° 45' N., with an extreme length of about 770 km (415 nautical miles, 480 mi). It has a mean breadth of about 160 km (85 nautical miles, 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).

The chain of islands which fringes the northern section of the eastern shore reduces the extreme breadth of open sea in this area 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 Šibenik 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).

Coasts and islands

The east and west coasts of the Adriatic vary greatly. The west shore, along Italy, is relatively straight, continuous, and generally low, merging in the northwest, into the marshes and lagoons on either hand of the protruding delta of the River Po, the sediment of which has pushed forward the coastline for several miles within historic times — Adria is now some distance from the shore.

The east coast along the Balkan Peninsula is generally bold and rocky, with over one thousand islands varying in size. Numerous straits form inlets between the islands similar to those of the Norwegian fjords, forming an intricate coastline. South of the Istrian Peninsula, which separates the Gulfs of Venice and Gulf of Trieste from the Bay of Kvarner, the island-fringe of the east coast extends as far south as Dubrovnik.

The islands, which are long and narrow (the long axis lying parallel with the coast of the mainland), rise rather abruptly to elevations of a few hundred feet, with the exception of a few larger islands such as Brač (Vidova gora, 778 m) or the peninsula Pelješac (St. Ilija, 961 m). There are over a thousand islands in the Adriatic, 66 of which are inhabited. On the mainland, notably in the Gulf of Kotor (Boka Kotorska; named after the town of Kotor), lofty mountains often fall directly to the sea.

The prevalent color of the rocks is a light, dead grey, contrasting harshly with the dark vegetation, which on some of the islands is luxuriant. Attesting to this, Montenegro (Black Mountain) was named for the black pines that cover the coast there, and similarly the Greek name for the island of Korčula is Korkyra Melaina meaning "Black Corfu".

Notable cities on the Italian coast are Trieste, Ravenna, Rimini, Ancona, Pescara, Bari and Brindisi. The city of Venice stretches across numerous small islands in the marshy Venetian Lagoon, which stretches along the shoreline of the Adriatic in northeast Italy between the mouths of the Po (south) and the Piave (north) Rivers.

Major cities on the northeastern coast include Trieste in Italy; Koper in Slovenia; Umag, Poreč, Rovinj, Pula, Opatija, Rijeka, Senj, Zadar, Biograd, Šibenik, Trogir, Split, Makarska, Ploče and Dubrovnik in Croatia; Neum in Bosnia and Herzegovina; Herceg Novi, Kotor, Tivat, Bar, Budva and Ulcinj in Montenegro; and Durrës in Albania.

Weather patterns

The bora (northeast wind), and the prevalence of sudden squalls from this quarter or the southeast, are dangers to navigation in winter. Also notable are sirocco (southern wind) which brings rain in the winter and maestral (western wind) which brings clear weather in the summer.

Tidal movement is slight. The amphidromic point is just off the northwestern shore, near Ancona.
