141-596: Hvar's location at the north east centre of the Adriatic sailing routes has long made this island an important base for commanding trade up and down the Adriatic, across to Italy and throughout the wider Mediterranean . It has been inhabited since prehistoric times, originally by a Neolithic people whose distinctive pottery gave rise to the term Hvar culture , and later by the Illyrians . The ancient Greeks founded

282-594: A Catholic city—before proceeding to sack Constantinople . In the 13th century, Venice established itself as a leading maritime nation . During much of the 12th and 13th centuries, Venice and the Republic of Genoa were engaged in warfare culminating in the War of Chioggia , ousting the Genoese from the Adriatic. Still, the 1381 Treaty of Turin that ended the war required Venice to renounce claims to Dalmatia, after losing

423-645: A counterclockwise direction, thus bringing clearer waters up the eastern coast and returning increasingly polluted water down the western coast. This circulation has significantly contributed to the biodiversity of the countries along the eastern Adriatic coast; the common bottlenose dolphin is frequent in the eastern coast's waters only, and the Croatian coast provides refuge for the critically endangered monk seal and sea turtles. Recent studies revealed that cetaceans and other marine megafaunas , that were once thought to be vagrants to Adriatic Sea, migrate and live in

564-529: A few days a year, the worst-case sea level rise scenario between 2050 and 2100 would prompt deployment up to 187 days a year, essentially cutting off the Venetian Lagoon from the Adriatic Sea. Among other possible adverse effects, this can be expected to lower the lagoon's oxygen levels and trap pollution inside of the city. Geophysical and geological information indicate that the Adriatic Sea and

705-591: A major concern in terms of potential environmental impact and damage to tourism and fisheries. It is estimated that if a major oil spill happened, a million people would lose their livelihoods in Croatia alone. An additional risk is presented by oil refineries in the Po River basin where oil spills have occurred before, in addition to accidents occurring in the Adriatic already, so far with no significant environmental consequences. Since 2006, Italy has been considering

846-506: A million tonnes of cargo per year. The largest Adriatic seaport by annual cargo turnover is the Port of Trieste , while the Port of Split is the largest Adriatic seaport by passengers served per year. The origins of the name Adriatic are linked to the Illyrian settlement of Adria , which probably derives its name from Illyrian adur 'water, sea'. In classical antiquity , the sea

987-501: A more peaceful and prosperous time. On the coast, harbours were expanded, quays built, fishing and boat building businesses grew. At the same time, the island's wine exports increased, along with lavender and rosemary production for the French perfume industry. However, this prosperity did not continue into the 20th century as wooden sailing boats went out of fashion, and the phylloxera blight hit wine production. Many islanders left to make

1128-465: A national park in 1999. The Lim Canal is a 10-kilometre (6.2 mi) ria of the Pazinčica river. The Kornati national park was established in 1980; it covers approximately 220 square kilometres (85 sq mi), including 89 islands and islets. The marine environment encompasses three-quarters of the total area, while the island shores' combined length equals 238 kilometres (148 mi). Telašćica

1269-611: A new elevation benchmark referring to the upgraded tide gauge station in the coastal town of Koper . The Alps, which also have a large meteorological impact on the Mediterranean, touch the Adriatic in the area around Trieste towards Duino and Barcola . The Adriatic Sea contains more than 1,300 islands and islets , most along the Adriatic's eastern coast—especially in Croatia, with 1,246 counted. The number includes islands, islets, and rocks of all sizes, including ones emerging at ebb tide only. The Croatian islands include

1410-404: A new life elsewhere. One industry, tourism , has however continued to grow and is now a significant contributor to the island's economy. The formation of The Hygienic Association of Hvar in 1868 for the assistance of visitors to the island has been instrumental in developing an infrastructure of hotels, apartments, restaurants, marinas, museums, galleries and cafés . Today, the island of Hvar

1551-618: A sea surface of 2,227 hectares (5,500 acres) and is adjacent to the Torre Guaceto State Reserve covering 1,114 hectares (2,750 acres) of coast and sharing an 8-kilometre (5.0 mi) coastline with the marine protected area. Furthermore, there are 10 internationally important (Ramsar) wetland reserves in Italy located along the Adriatic coast. There are seven marine protected areas in Croatia: Brijuni and

1692-630: A season. The predominant winter winds are the bora and sirocco (called jugo along the eastern coast). The bora is significantly conditioned by wind gaps in the Dinaric Alps bringing cold and dry continental air; it reaches peak speeds in the areas of Trieste, Senj , and Split , with gusts of up to 180 kilometres per hour (97 kn; 110 mph). The sirocco brings humid and warm air, often carrying Saharan sand causing rain dust . [REDACTED] Bari [REDACTED] Venice [REDACTED] Trieste [REDACTED] Durrës On

1833-495: A series of 79 inflatable pontoons across the sea bed at the three entrances to the Venetian Lagoon . When tides are predicted to rise above 110 centimetres (43 in), the pontoons will be filled with air and block the incoming water from the Adriatic Sea. This engineering work was due to be completed by 2014, but as of November 2020 is expected to be completed in 2021. Implemented for the first time on October 3, 2020,

1974-712: A snake. The two animals symbolize the Pharian Greeks (goat) and the Illyrians (snake). Their victory over much larger forces was immortalized in one of the oldest known inscriptions of Croatia. Following Roman victory in the Second Illyrian War against Demetrius of Pharos , the island became a part of the Roman Republic in 219 BC and the Greek name Pharos was changed to Pharia. After the fall of

2115-670: A third of the fresh water flowing into the Mediterranean, acting as a dilution basin . The surface water temperatures generally range from 30 °C (86 °F) in summer to 12 °C (54 °F) in winter, significantly moderating the Adriatic Basin 's climate. The Adriatic Sea sits on the Apulian or Adriatic Microplate , which separated from the African Plate in the Mesozoic era . The plate's movement contributed to

2256-566: A wide range of soil types, Corsican origins grows poorly on limestone , while Turkish and Crimean origins grow well on limestone. Most provenances also show good growth on podzolic soils. Pinus nigra has become naturalised in a few areas of the US. In New Zealand it is considered an invasive species and noxious weed , along with lodgepole pine ( P. contorta ) and Scots pine ( P. sylvestris ), due to their habitat conversion nature in tussock grassland plant communities, shading out

2397-533: A yellow-buff wing 20–25 mm ( 3 ⁄ 4 –1 in) long; they are wind-dispersed when the cones open from December to April. maturity is reached at 15–40 years; large seed crops are produced at 2–5 year intervals. Pinus nigra is moderately fast growing, at about 30–70 cm (12–28 in) per year. It usually has a rounded conic form, that becomes irregular with age. The tree can be long-lived, with some trees over 500 years old. Multiple pests can damage P. nigra , including T. piniperda . The species

2538-490: Is hot-summer Mediterranean ( Csa in the Köppen climate classification ). It has mild winters and hot summers. The yearly average air temperature is 16 °C (61 °F), 703 mm (27.7 in) of precipitation fall on Hvar on average every year and the town has a total of 2800 sunshine hours per year. For comparison Hvar has an average of 7.7 sunshine hours per day while Dubrovnik has 7.2. The sea temperatures average from

2679-623: Is 68 kilometres (42 mi) long, and only 10.5 kilometres (6.5 mi) at its widest point. It covers an area of 297 square kilometres (115 sq mi), the 4th largest of the Adriatic islands by area, and has a coastline length of 254.2 kilometres (158.0 mi). The highest peak is Sv. Nikola, at 628 metres (2,060 ft). The island is part of Split-Dalmatia County in Dalmatia , Croatia. The island has two towns ( Hvar and Stari Grad ) and two municipalities ( Jelsa and Sućuraj ). Population figures are from 2021. The climate of Hvar

2820-855: Is a body of water separating the Italian Peninsula from the Balkan Peninsula . The Adriatic is the northernmost arm of the Mediterranean Sea , extending from the Strait of Otranto (where it connects to the Ionian Sea ) to the northwest and the Po Valley . The countries with coasts on the Adriatic are Albania , Bosnia and Herzegovina , Croatia , Italy , Montenegro , and Slovenia . The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It

2961-432: Is a light-demanding species, intolerant of shade but resistant to wind and drought. The eastern P. nigra subsp. nigra exhibits greater winter frost hardiness (hardy to below −30 °C) than the western P. nigra subsp. salzmannii (hardy to about −25 °C). Different provenances (seed sources by geographic area) or varieties are adapted to different soil types: Austrian and Pyrenees origins grow well on

3102-492: Is a nature park established on Dugi Otok in 1988. The park covers 69 kilometres (43 mi) of coastline, 22.95 square kilometres (8.86 sq mi) of land and 44.55 square kilometres (17.20 sq mi) of sea. The Bay of Mali Ston is located at the border of Croatia and Bosnia–Herzegovina, north of the Pelješac peninsula. The marine protected area covers 48 square kilometres (19 sq mi). The Lastovo nature park

3243-763: Is a tourist destination, consistently listed in the top 10 islands by Conde Nast Traveler magazine. The island of Hvar is located in the Adriatic Sea , off the Dalmatian coast. To the north, the island of Brač lies across the Hvar Channel ( Hvarski kanal ), to the west is Vis , separated by the Vis Channel, and to the south Korčula lies across the Korčula Channel, while the Pelješac Peninsula

3384-608: Is across the Neretva Channel. The eastern end of Hvar is just 6 kilometres (3.7 mi) from the mainland. Along the southern coast of the island there are several smaller islands, notably the Paklinski islands at the western end and Šćedro island, while Zečevo island lies off the north coast. Hvar is a high east–west ridge of Mesozoic limestone and dolomite , which was part of the mainland until approximately 11,000 years ago. Around that time, sea levels rose, filling

3525-435: Is also a site of international importance for waterbird species. The 429-hectare (1,060-acre) Strunjan Landscape Park was established in 2004 and comprises two nature reserves. It includes a 4 kilometres (2.5 mi) long cliff, the northernmost Mediterranean salt field and the only Slovenian lagoon system. It is also the northernmost point of growth of some Mediterranean plant species. The Škocjan Inlet Nature Reserve

3666-570: Is also one of the two most famous winemaking zones in Croatia. Vineyards on the southern side of the island are famous for red wines produced from the Plavac Mali grape. The central plain between Stari Grad and Jelsa is famous for its white wines. As a Greek colony , the island initially was known as Paros (Πάρος) because it was colonized by Greeks from the island of Paros in Aegean , and later as Pharos (Φάρος) "lighthouse". However, it

3807-494: Is at the mid-width east of Ancona. The normal tide levels are known to increase significantly in a conducive environment, leading to coastal flooding ; this phenomenon is most famously known in Italy—especially Venice—as acqua alta . Such tides can exceed normal levels by more than 140 centimetres (55 in), with the highest tide level of 194 centimetres (76 in) observed on 4 November 1966. Such flooding

3948-464: Is caused by a combination of factors, including the alignment of the Sun and Moon , meteorological factors such as sirocco related storm surges, and the basin's geometric shape (which amplifies or reduces the astronomical component). Moreover, the Adriatic's long and narrow rectangular shape is the source of an oscillating water motion ( French : seiche ) along the basin's minor axis. Finally, Venice

4089-453: Is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of 1,233 metres (4,045 ft). The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects

4230-526: Is divided into two subspecies, each further subdivided into three varieties. Some authorities (e.g. Flora Europaea ) treat several of the varieties at subspecific rank, but this reflects tradition rather than sound taxonomy, as the distinctions between the taxa are small. Pinus nigra is a tree of the Mediterranean forests, woodlands, and scrub biome . The majority of the range is in Turkey. It

4371-737: Is found in the higher elevations of the South Apennine mixed montane forests ecoregion in southern Italy and the Tyrrhenian-Adriatic sclerophyllous and mixed forests ecoregion in Sicily. There are remnant populations in the Mediterranean conifer and mixed forests ecoregion, and in the higher Atlas Mountains in Morocco and Algeria. It is found at elevations ranging from sea level to 2,000 m (6,600 ft), most commonly from 250–1,600 m (820–5,250 ft). Several of

4512-472: Is geographically divided into the Northern Adriatic, Central (or Middle) Adriatic, and Southern Adriatic. The Adriatic Sea drainage basin encompasses 235,000 square kilometres (91,000 sq mi), yielding a land–sea ratio of 1.8. The drainage basin's mean elevation is 782 metres (2,566 ft) above sea level, with a mean slope of 12.1°. Major rivers discharging into the Adriatic include

4653-633: Is gray to yellow-brown, and is widely split by flaking fissures into scaly plates, becoming increasingly fissured with age. The leaves ('needles') are thinner and more flexible in western populations. The ovulate and pollen cones appear from May to June. The mature seed cones are 5–10 centimetres (2–4 inches) (rarely to 11 cm) long, with rounded scales; they ripen from green to pale gray-buff or yellow-buff in September to November, about 18 months after pollination. The seeds are dark gray, 6–8 millimetres ( 1 ⁄ 4 – 5 ⁄ 16  in) long, with

4794-491: Is important both as a timber tree and in plantations (primarily Corsican pine subsp.). Recently however, serious problems have occurred with red band needle blight disease, caused by the fungus Dothistroma septosporum , resulting in a major recent decline in forestry planting there. In the United States it is of low importance as a timber species. In regard to Austrian pine, the fungus Dothistroma septosporum

4935-499: Is increasingly vulnerable to flooding due to coastal area soil subsidence . Such unusually high tides resulting in flooding have also been observed elsewhere in the Adriatic Sea, and have been recorded in recent years in the towns of Koper , Zadar and Šibenik as well. It is estimated that the Adriatic's entire volume is exchanged through the Strait of Otranto in 3.4±0.4 years, a comparatively short period. (For instance, approximately 500 years are necessary to exchange all

5076-403: Is not clear if the name really comes from the Greek word for lighthouse. It was more likely an Illyrian word "Fara" that in modern Albanian, translates to seed!since it is unlikely that the lighthouse preceded the name for the island. During the 3rd century BC, the Greek poet Apollonius of Rhodes referred to it as Piteyeia – a name derived from the Greek word pitys , meaning pine tree . From

5217-403: Is planted with great success as far north as Edmonton, Alberta, Canada. In both the US and UK most of the specimens planted are from Austrian sources, the P. nigra subsp. nigra and P. nigra subsp. nigra var. nigra seed selections. In the late 1950s and early 1960s, when demand for natural trees was extremely high, its rapid growth, deep green color and low cost made it briefly

5358-586: Is presented by ballast water discharge by ships, especially tankers . Still, since most of the cargo handled by the Adriatic ports, and virtually all liquid (tanker) cargo handled by the ports, is coming to—not coming from—the Adriatic Basin, the risk from ballast water (from tankers expelling ballast water then loading in the Adriatic) remains minimal. However, proposed export oil pipelines were objected to specifically because of this issue. Oil spills are

5499-421: Is shallower and closer to land than are oceans. During particularly cold winters, sea ice may appear in the Adriatic's shallow coastal areas, especially in the Venetian Lagoon but also in isolated shallows as far south as Tisno (south of Zadar). The Southern Adriatic is about 8 to 10 °C (14 to 18 °F) warmer during the winter than the more northerly regions. The Adriatic's salinity variation over

5640-425: Is the main tourist centre. It features a large public square (St Stephen's Square/ trg Sv. Stjepana ) that is open to the sea. During the tourist season, the port is filled with large yachts and sailboats . All-night discos attract large crowds of young visitors. Another major economic activity is the cultivation of lavender , used for aromatic oils and soaps. Hvar is often called the "island of lavender". Hvar

5781-663: Is the most indented Mediterranean coastline. Most of the eastern coast is characterised by a karst topography, developed from the Adriatic Carbonate Platform's exposure to weathering. Karstification there largely began after the Dinarides' final uplift in the Oligocene and the Miocene , when carbonate deposits were exposed to atmospheric effects; this extended to the level of 120 metres (390 ft) below

5922-473: Is threatened by excessive input of nutrients through drainage from agricultural land and wastewater flowing from cities; this includes both along its coast and from rivers draining into the sea—especially from the Po River . Venice is often cited as an example of polluted coastal waters where shipping, transportation, farming, manufacturing and wastewater disposal contribute to polluting the sea. A further risk

6063-481: Is widespread and rapidly spreading out of control throughout the United States. It is out of control and not recommended for landscaping, especially in groups or rows. In Turkey, this pine (subsp. pallasiana) was and is used in various ways, both topically and internally, as well as for construction and for livestock. Among its uses are curing acne , common cold , osteomyelitis , and viral infections ; acting as an oral antiseptic ; treating cracked hands and feet in

6204-631: The Apennine Mountains are further away from the shoreline. The coastal water dynamics are determined by the asymmetric coasts and the inflow of the Mediterranean seawater through the Straits of Otranto and further on along the eastern coast. The smooth Italian coast (with very few protrusions and no major islands) allows the Western Adriatic Current to flow smoothly, which is composed of the relatively freshwater mass on

6345-627: The Black Sea 's water.) This short period is particularly important as the rivers flowing into the Adriatic discharge up to 5,700 cubic metres per second (200,000 cu ft/s). This rate of discharge amounts to 0.5% of the total Adriatic Sea volume, or a 1.3-metre (4 ft 3 in) layer of water each year. The greatest portion of the discharge from any single river comes from the Po (28%), with an average discharge from it alone of 1,569 cubic metres per second (55,400 cu ft/s). In terms of

6486-743: The Ionian Sea at the 72-kilometre (45 mi) wide Strait of Otranto . The International Hydrographic Organization (IHO) defines the boundary between the Adriatic and the Ionian seas as a line running from the Butrinto River 's mouth ( latitude 39°44'N) in Albania to the Karagol Cape in Corfu , through this island to the Kephali Cape (these two capes are in latitude 39°45'N), and on to

6627-663: The Karaburun Peninsula where the Adriatic and Ionian Seas meet. The park covers a total of 12,570 hectares (31,100 acres). Two additional marine protection areas are planned in Albania: the Cape of Rodon ( Albanian : Kepi i Rodonit ) and Porto Palermo . In addition, Albania is home to two Ramsar wetland reserves: Karavasta Lagoon , and Butrint . Neither Bosnia–Herzegovina nor Montenegro have or plan to establish any marine protection areas. The Adriatic Sea ecosystem

6768-576: The Late Oligocene , the motion was reversed and the Apennine Mountains' orogeny took place. An unbroken zone of increased seismic activity borders the Adriatic Sea, with a belt of thrust faults generally oriented in the northeast–southwest direction on the east coast and the northeast–southwest normal faults in the Apennines, indicating an Adriatic counterclockwise rotation. An active 200-kilometre (120 mi) fault has been identified to

6909-594: The Lim Canal off the Istria peninsula's coast, near Pula and Rovinj respectively; Kornati and Telašćica in the Middle Adriatic basin, near Zadar ; and Lastovo , Bay of Mali Ston ( Croatian : Malostonski zaljev ) and Mljet in southern Dalmatia. The Brijuni national park encompasses the 743.3-hectare (1,837-acre) archipelago itself and 2,651.7 hectares (6,552 acres) of surrounding sea; it became

7050-611: The Po River delta, where an emporium (trading station) was founded in Adria . Roman economic and military influence in the region began to grow with the creation by 246 BC of a major naval base at Brundisium (now Brindisi ), which was established to bar Carthaginian ships from the Adriatic during the Punic Wars . This led to conflict with the Illyrians , who lived in a collection of semi- Hellenized kingdoms that covered much of

7191-616: The Po Valley are associated with a tectonic microplate —identified as the Apulian or Adriatic Plate —that separated from the African Plate during the Mesozoic era . This separation began in the Middle and Late Triassic , when limestone began to be deposited in the area. Between the Norian and Late Cretaceous , the Adriatic and Apulia Carbonate Platforms formed as a thick series of carbonate sediments ( dolomites and limestones), up to 8,000 metres (26,000 ft) deep. Remnants of

7332-594: The Po Valley , at the Adriatic's north-west coast, and as far west as Piacenza , dating to the Pleistocene as the sea advanced and receded over the valley. An advance began after the Last Glacial Maximum, which brought the Adriatic to a high point at about 5,500 years ago. Since then, the Po delta has been prograding (expanding/extending). The rate of coastal zone progradation between 1000 BC and 1200 AD

7473-651: The Roman Empire in the west, the island was under the control of the Byzantine or Eastern Roman Empire. The population increased in the Late Antiquity with an abundance of archaeological finds. A large number of new villa rustica in Stari Grad Plain and also on the previously vacant eastern shores were built. In the early Middle Ages, Slavic tribes occupied the island. In the first half of

7614-427: The Santa Maria di Leuca Cape (latitude 39°48'N). It extends 800 kilometres (500 mi) from the northwest to the southeast and is 200 kilometres (120 mi) wide. It covers 138,600 square kilometres (53,500 sq mi) and has a volume of 35,000 cubic kilometres (8,400 cu mi). The Adriatic extends northwest from 40° to 45° 47' north, representing the Mediterranean 's northernmost portion. The sea

7755-426: The Via Egnatia , a road that by about 130 BC the Romans had extended eastward across the Balkans to Byzantium (later Constantinople , now Istanbul ). This made the sea passage across the Adriatic between Brundisium and Dyrrachium (or Apollonia) a link in the primary route for travelers, trade, and troop movements, between Rome and the East. This route played a major role in some of the military operations that marked

7896-431: The formation of the surrounding mountain chains and Apennine tectonic uplift after its collision with the Eurasian Plate . In the Late Oligocene , the Italian Peninsula first formed, separating the Adriatic Basin from the rest of the Mediterranean. The western coast is alluvial or terraced , while the eastern coast is highly indented with pronounced karstification . There are dozens of marine protected areas in

8037-410: The maritime republics , was founded during this period and went on to become a significant maritime power after receiving a Byzantine tax exemption in 1082. The end of the period brought about the Holy Roman Empire 's control over the Kingdom of Italy (which would last until the Peace of Westphalia in 1648), the establishment of an independent Kingdom of Croatia and the Byzantine Empire's return to

Further on to the south, the sea floor rises to 780 metres (2,560 ft) to form the Otranto Sill at the boundary to the Ionian Sea. The South Adriatic Basin is similar in many respects to the Northern Ionian Sea, to which it is connected. Transversely, the Adriatic Sea is also asymmetric:

The project proposes laying

8460-399: The 2nd century BC, the region was under Rome 's control. In the Middle Ages , the Adriatic shores and the sea itself were controlled, to a varying extent, by a series of states—most notably the Byzantine Empire , the Croatian Kingdom , the Republic of Venice , the Habsburg monarchy and the Ottoman Empire . The Napoleonic Wars resulted in the Austrian Empire gaining control of most of

8601-402: The 7th century onwards, the Byzantine Theme of Dalmatia , including Fara , was settled by the Pannonian Avars and Croats . However, the population initially remained culturally Illyro-Roman and part of the Byzantine Roman world. Under the linguistic influence of the newcomers, the official name became Quarra – because the Slavic languages did not originally have the /f/-sound . Later,

8742-482: The 7th century the Narentines took over the island. Venetian sailors saw the island while sailing towards the south and were threatened by the Narentine pirates from the island. In the 11th century the island joined the Kingdom of Croatia . In the 12th century, the rise of the Republic of Venice brought vines and wine cultivation which blossomed into a major industry for the island in the Middle Ages. The island eventually again fell under Byzantine rule, and then under

8883-428: The Adriatic Sea in Italy alone, also forming alluvial coastlines, including the lagoons of Venice , Grado and Caorle . There are smaller eastern Adriatic alluvial coasts—in the deltas of the Dragonja, Buna and Neretva rivers. The Adriatic Sea is a unique water body in respect of its overall biogeochemical physiognomy. It exports inorganic nutrients and imports particulate organic carbon and nitrogen through

9024-426: The Adriatic Sea's coasts and islands, there are numerous small settlements and a number of larger cities. Among the largest are (counterclockwise) Trieste, Venice, Rimini, Ancona, Pescara and Bari in Italy; Vlorë and Durrës in Albania; Split, Zadar and Rijeka in Croatia; Koper in Slovenia. In total, more than 3.5 million people live on the Adriatic coasts. There are also some larger cities that are located very near

9165-475: The Adriatic Sea. Exclusive economic zones in Adriatic Sea: The Adriatic Sea's average depth is 259.5 metres (851 ft), and its maximum depth is 1,233 metres (4,045 ft); however, the North Adriatic basin rarely exceeds a depth of 100 metres (330 ft). The North Adriatic basin, extending between Venice and Trieste towards a line connecting Ancona and Zadar , is only 15 metres (49 ft) deep at its northwestern end; it gradually deepens towards

9306-493: The Adriatic Sea. The Northern Adriatic's comparatively shallow seabed is characterised by relict sand (from times when the water level was lower and the area was a sandy beach), while a muddy bed is typical at depths below 100 metres (330 ft). There are five geomorphological units in the Adriatic: the Northern Adriatic (up to 100 metres (330 ft) deep); the North Adriatic islands area protected against sediments filling it in by outer islands (pre- Holocene karst relief);

9447-401: The Adriatic Sea. The most common species are Cymodocea nodosa and Zostera noltii , while Zostera marina and Posidonia oceanica are comparatively rare. A number of rare and threatened species are also found along the Adriatic's eastern coast; it is relatively clearer and less polluted than the western Adriatic coast—in part because the sea currents flow through the Adriatic in

9588-467: The Adriatic Sea. These are particularly due to or dependent upon the karst morphology of the coastal or submarine topography; this includes inhabiting subterranean habitats, karst rivers, and areas around freshwater springs. There are 45 known subspecies endemic to the Adriatic's coasts and islands. In the Adriatic, there are at least 410 species and subspecies of fish, representing approximately 70% of Mediterranean taxa, with at least 7 species endemic to

9729-399: The Adriatic for a few centuries. The last part of the period saw the rise of the Carolingian Empire and then the Frankish Kingdom of Italy , which controlled the Adriatic Sea's western coast, while Byzantine Dalmatia on the east coast gradually shrunk into Dalmatian city-states following the Avar and Croatian invasions starting in the 7th century. The Republic of Venice , one of

9870-430: The Adriatic is solid waste. Drifting waste—occasionally relatively large quantities of material, especially waste plastic—is transported northwest by the sirocco. Air pollution in the Adriatic Basin is associated with the large industrial centres in the Po River valley and the large industrial cities along the coast. Italy and Yugoslavia established a joint commission to protect the Adriatic Sea from pollution in 1977;

10011-463: The Adriatic's coasts were ruled by Ostrogoths , Lombards and the Byzantine Empire . The Ostrogothic Kingdom ruled Italy following the fall of the Western Roman Empire in 476 AD. However, during the reign of Justinian the Byzantine Empire sent an army under the general Belisarius to regain control of Italy, resulting in the Gothic War (535–554) . The Byzantines established the Exarchate of Ravenna and by 553 AD their viceroy (Exarch) ruled almost

10152-411: The Adriatic, designed to protect the sea's habitats and biodiversity—more than 7,000 species are identified as native to the Adriatic, many of them endemic , rare and threatened ones. The Adriatic's shores are populated by more than 3.5 million people; the largest cities are Bari , Venice , Trieste and Split . Early settlements on the Adriatic shores were Etruscan , Illyrian , and Greek . By

10293-437: The Adriatic. Sixty-four known species are threatened with extinction, largely because of overfishing. Only a small fraction of the fish found in the Adriatic are attributed to recent processes such as Lessepsian migration , and escape from mariculture . The biodiversity of the Adriatic is relatively high, and several marine protected areas have been established by countries along its coasts. In Italy, these are Miramare in

10434-633: The Apennine peninsular coast is relatively smooth with very few islands and the Mount Conero and Gargano promontories as the only significant protrusions into the sea; in contrast, the Balkan peninsular coast is rugged with numerous islands, especially in Croatia. The coast's ruggedness is exacerbated by the Dinaric Alps ' proximity to the coast, in contrast to the opposite (Italian) coast where

10575-744: The Balkans and controlled the eastern shore of the sea, resulting in the Illyrian Wars from 229 to 168 BC. The initial Roman intervention in 229 BC, motivated in part by a desire to suppress Illyrian piracy in the Adriatic, marked the first time that the Roman navy crossed that sea to launch a military campaign. Those wars ended with the eastern shore becoming a province of the Roman Republic. However, resistance to Roman rule continued sporadically and Rome did not completely consolidate control of

10716-620: The Gulf of Trieste (in the Northern Adriatic), Torre del Cerrano and Tremiti Islands in the Middle Adriatic basin and Torre Guaceto in southern Apulia. The Miramare protected area was established in 1986 and covers 30 hectares (74 acres) of coast and 90 hectares (220 acres) of sea. The area encompasses 1.8 kilometres (1.1 mi) of coastline near the Miramare promontory in the Gulf of Trieste. The Torre del Cerrano protected area

10857-570: The Gulf of Trieste coast, especially along Slovenia's coast where the 80-metre (260 ft) Strunjan cliff —the highest cliff on the entire Adriatic and the only one of its type on the eastern Adriatic coast—is located, on the Kvarner Gulf coast opposite Krk, and in Dalmatia north of Split. Rocks of the same type are found in Albania and on the western Adriatic coast. There are alternations of maritime and alluvial sediments occurring in

10998-698: The Kingdom of Croatia and Hungary. In 1331 the Venetians put the island under protection from threats of piracy. According to the 1358 Treaty of Zadar , the island was handed over to the Kingdom of Hungary . For short time in the summer of 1390, it was held by the Bosnian king Stephen Tvrtko I . In 1409, the Republic of Venice finally again became its long-term owner. The island became prosperous from fishing, and

11139-673: The Middle Adriatic islands area (large Dalmatian islands); the Middle Adriatic (characterized by the Middle Adriatic Depression); and the Southern Adriatic consisting of a coastal shelf and the Southern Adriatic Depression. Sediments deposited in the Adriatic Sea today generally come from the northwest coast, being carried by the Po, Reno , Adige , Brenta , Tagliamento , Piave and Soča rivers. The volume of sediments carried from

11280-560: The Northern Adriatic, the Central Adriatic, and the Southern Adriatic. The unique nature of the Adriatic gives rise to an abundance of endemic flora and fauna. The Croatian National Biodiversity Strategy Action Plan identified more than 7,000 animal and plant species in the Adriatic Sea. The Central Adriatic is especially abundant in endemic plant species, with 535 identified species of green , brown and red algae . Four out of five Mediterranean seagrass species are found in

11421-532: The Northern Adriatic, the coast of the Gulf of Trieste and western Istria is gradually subsiding, having sunk about 1.5 metres (4 ft 11 in) in the past two thousand years. In the Middle Adriatic Basin, there is evidence of Permian volcanism in the area of Komiža on the island of Vis and the volcanic islands of Jabuka and Brusnik . Earthquakes have been observed in the region since

11562-535: The Po, Soča , Krka , Neretva , Drin , Buna , and Vjosë . In the late 19th century, Austria-Hungary established a geodetic network with an elevation benchmark using the average Adriatic Sea level at the Sartorio pier in Trieste , Italy . The benchmark was subsequently retained by Austria , adopted by Yugoslavia , and retained by the states that emerged after its dissolution . In 2016, Slovenia adopted

11703-636: The Strait of Otranto—acting as a mineralization site. The exchange of the substances is made more complex by bathymetry of the Adriatic Sea—75% of water flowing north through the strait recirculates at the Palagruža Sill and North Adriatic adds no more than 3–4% of water to the South Adriatic. This is reflected in its biogeography and ecology , and particularly in the composition and properties of its ecosystems . Its main biogeographic units are

11844-515: The annual total discharge into the entire Mediterranean Sea, the Po is ranked second, followed by the Neretva and Drin , which rank as third and fourth. Another significant contributor of freshwater to the Adriatic is the submarine groundwater discharge through submarine springs ( Croatian : vrulja ); it is estimated to comprise 29% of the total water flux into the Adriatic. The submarine springs include thermal springs , discovered offshore near

11985-444: The barriers are made to seal off three inlets that lead to the Venetian Lagoon and counteract floods of up to ten feet; in addition to protecting the city from flooding, the barrier system is also intended to stabilize Venice's water levels so as to minimize erosion of the brick walls and, subsequently, the foundations of various buildings in the city. However, concern has been raised regarding the frequency of its use—while only necessary

12126-469: The boundary between the Adriatic and Ionian seas at various places ranging from adjacent to the Gulf of Venice to the southern tip of the Peloponnese , eastern shores of Sicily and western shores of Crete . Mare Superum on the other hand normally encompassed both the modern Adriatic Sea and the sea off the Apennine peninsula's southern coast, as far as the Strait of Sicily . Another name used in

12267-540: The campaign moved inland. Marc Antony and Octavian (later Augustus) crossed the Adriatic to Dyrrachium with their armies in their campaign against two of Caesar's assassins, Brutus and Cassius , that culminated in the Battle of Philippi . Brundisium and Dyrrachium remained important ports well after the Roman period, but an earthquake in the 3rd century AD changed the path of a river causing Apollonia's harbor to silt up, and

12408-614: The city to decline. Another city on the Italian coast of the Adriatic that increased in importance during the Roman era was Ravenna . During the reign of Augustus, it became a major naval base as part of his program to re-organize the Roman navy to better protect commerce in the Mediterranean. During the 4th century AD the emperors of the Western Roman Empire had moved their official residence north from Rome to Mediolanum (now Milan ) in order to be better able to control

12549-489: The coast, such as the Italian cities of Ravenna and Lecce . Venice , which was originally built on islands off the coast, is most at risk due to subsidence, but the threat is present in the Po delta as well. The causes are a decrease in sedimentation rate due to loss of sediment behind dams, the deliberate excavation of sand for industrial purposes, agricultural use of water, and removal of ground water. The sinking of Venice slowed after artesian wells were banned in

12690-601: The colony of Pharos in 384 BC on the site of today's Stari Grad , making it one of the oldest towns in Europe . They were also responsible for setting out the agricultural field divisions of the Stari Grad Plain , now a UNESCO World Heritage Site . In medieval times, the town of Hvar rose to importance within the Venetian Empire as a major naval base. Prosperity brought culture and the arts, with one of

12831-478: The construction of an offshore and an onshore LNG terminal in the Gulf of Trieste , as well as a pipeline, in the immediate vicinity of the Slovenian–Italian border. The Slovenian government and municipalities, the municipal council of Trieste, and non-governmental organisations have voiced concern over their environmental hazards, effect on transport and effect on tourism. Another source of pollution of

12972-518: The control of a substantial part of the eastern Adriatic coast by the Kingdom of Hungary after a personal union was established between Croatia and Hungary in 1102. In this period, the Republic of Venice began to expand its territory and influence. In 1202, the Fourth Crusade was diverted to conquer Zadar at the behest of the Venetians—the first instance of a Crusader force attacking

13113-671: The cultivation of rosemary, lavender and olives. Hvar is important to the history of Croatia as it was one of the centres of Croatian literature during the Renaissance , with writers such as Petar Hektorović and Hanibal Lucić . In Stari Grad, tourists can see the Petar Hektorović fortress/villa called Tvrdalj Castle , architectonically designed by the poet himself. Churches on the island contain many important paintings and artworks by famous Venetian artists, including Tintoretto , Veronese , Bellini and others. In 1797 Hvar

13254-480: The earliest historical records. A recent strong earthquake in the region was the 1979 Montenegro earthquake , measuring 7.0 on the Richter scale . Historical earthquakes in the area include the 1627 Gargano peninsula and the 1667 Dubrovnik earthquakes, both followed by strong tsunamis. In the last 600 years, fifteen tsunamis have occurred in the Adriatic Sea. All types of seafloor sediments are found in

13395-636: The eastern Adriatic coast, related to the Cardium pottery culture. During classical antiquity, Illyrians inhabited the eastern coast, and the western coast was inhabited by the peoples of Ancient Italy , mainly Etruscans , before the Roman Republic 's rise. Greek colonisation of the Adriatic dates back to the 7th and 6th centuries BC when the ancient cities of Epidamnos and Apollonia were founded. The Greeks soon expanded further north establishing several cities, including Ancona , Black Corcyra , Epidaurus , Issa , with trade established as far north as

13536-578: The eastern Adriatic shore and the Po Valley, while the Kingdom of Italy gradually took control of the remaining Italian coast during the 19th century. Following the collapse of Austria-Hungary in 1918, control of the eastern coast passed to Yugoslavia and Albania, which agreed on their maritime boundaries with Italy in 1975 and 1992 respectively. After Yugoslavia's dissolution during the 1990s, its four coastal successor states—Slovenia, Croatia, Bosnia and Herzegovina, and Montenegro—continued to recognise

13677-534: The eastern shore by the Rječina , Zrmanja , Krka, Cetina , Ombla , Dragonja , Mirna , Raša and Neretva rivers is negligible, because these sediments are mostly deposited at the river mouths. The Adriatic's western shores are largely either alluvial or terraced , whereas the eastern shores are predominantly rocky, except for the southernmost part of the shore located in Albania that consists of sandy coves and rocky capes. The eastern Adriatic shore's Croatian part

13818-512: The eastern shores of the Mediterranean . The Hvar Culture lasted from 3500 to 2500 B.C. Beginning in the 4th century BC, the Greeks colonized the island. In 384 BC the Greek colonisers of Pharos defeated Iadasinoi warriors and their allies, invited by the Hvar indigenes in their resistance to the Greek colonization. The first coins which Pharos minted after the war depicted a goat standing opposed to

13959-600: The end of the Roman Republic and the start of the imperial period . Sulla used it during the First Mithridatic War . During Caesar's Civil War , there was a three-month delay in Caesar's Balkan campaign against Pompey caused when winter storms on the Adriatic and a naval blockade held up Mark Antony from reaching him from Brundisium with reinforcements; after the reinforcements finally arrived Caesar made an unsuccessful attempt to capture Dyrrachium before

14100-654: The entire Italian peninsula from that city. In 568 AD the Lombards invaded northern Italy, and over the course of the next century or so the importance of the Exarchate declined as the territory under Lombard control expanded and as the Byzantine outpost of Venice became increasingly independent. In 752 AD the Lombards overthrew the Exarchate, ending the influence of the Byzantine Empire on the western shore of

14241-649: The first public theatres in Europe, nobles' palaces and many fine communal buildings. The 16th century was an unsettled time, with the Hvar Rebellion , coastal raids by pirates and the Ottoman army from the mainland, resulting in some unusual fortified buildings on the northern shore to protect the local population. After a brief time under Napoleonic rule , the island became part of the Austrian Empire ,

14382-701: The former are found in the Adriatic Sea, as well as in the southern Alps and the Dinaric Alps , and remnants of the latter are seen as the Gargano Promontory and the Maiella mountain. In the Eocene and early Oligocene , the plate moved north and north-east, contributing to the Alpine orogeny (along with the African and Eurasian Plates ' movements) via the tectonic uplift of the Dinarides and Alps. In

14523-603: The former being intermittent and the latter permanent. The SAG measures 150 kilometres (93 miles) in diameter. It contributes to the flow of bottom water from the Adriatic to the Levantine Basin through the Ionian Sea. Through that process, the Adriatic Sea produces most of the East Mediterranean deep water. The Adriatic's surface temperature usually ranges from 22 to 30 °C (72 to 86 °F) in

14664-588: The high mountains of Northwest Africa. The world's oldest black pine, located in the Banaz district of Uşak, Türkiye, is estimated to be 1000 years old. This makes it significant in the country, which is known for a very dry climate, inhospitable for most trees. It has a length of 11 meters, a diameter of 3 meters and a circumference of 9.60 meters. Pinus nigra is a large coniferous evergreen tree , growing to 20–55 metres (66–180 feet) high at maturity and spreading to 6 to 12 m (20 to 39 ft) wide. The bark

14805-445: The island from 1918 until 1921, when Hvar with the rest of Croatia joined the Kingdom of Yugoslavia . In 1939, an autonomous Croatian Banate was formed that included the island. During WWII, it was under the control of Independent State of Croatia , but under military occupation of Fascist Italy until 1943. After 1945, it became a part of People's Republic of Croatia , a constituent republic of Communist Yugoslavia . Ivan Vučetić ,

14946-523: The largest— Cres and Krk , each covering about the same area of 405.78 square kilometres (156.67 sq mi)—and the tallest— Brač , whose peak reaches 780 metres (2,560 ft) above sea level. The islands of Cres and the adjacent Lošinj are separated only by a narrow navigable canal dug in the time of classical antiquity ; the original single island was known to the Greeks as Apsyrtides . The Croatian islands include 47 permanently inhabited ones ,

15087-508: The locals in the upper Adriatic for thousands of years. The very large schools consisted mainly of little tunny and moved as far as the Gulf of Trieste . However, increasing fishing prevented the migration of large schools of fish to the north. The last major tuna catch was made there in 1954 by the fishermen from Santa Croce, Contovello and Barcola . The Northern Adriatic in particular is rich in endemic fish fauna. Around thirty species of fish are found in only one or two countries bordering

15228-457: The lowest readings in February of 14 °C (57 °F) to their warmest during summer, when the sea temperatures usually stay between 23 °C (73 °F) to 27 °C (81 °F). The Köppen Climate Classification subtype for this climate is " Csa " (Mediterranean Climate). The first inhabitants of Hvar Island were Neolithic people who probably established trade links between Hvar and

15369-552: The man who perfected dactyloscopy at the turn of the 20th century, came from Hvar island. In the 21st century, Hvar's citizens include football player Igor Tudor and politician Tonči Tadić . Residents of Hvar mostly work in the fishing and tourism industries. Hvar has a very mild Mediterranean climate , several beaches and Mediterranean vegetation that make it one of the most attractive tourist centres in Europe. The island promotes itself as "the sunniest spot in Europe", with over 2715 hours of sunlight in an average year. Hvar town

15510-593: The marine and coastal protected nature areas are the Sečovlje Salina Landscape Park , Strunjan Landscape Park , Škocjan Inlet Nature Reserve , and the Debeli Rtič , Cape Madona and Lakes in Fiesa natural monuments. The Sečovlje Salina Landscape Park was established in 1990, covers 721 hectares (1,780 acres), and includes four nature reserves . In 1993, the area was designated a Ramsar site; it

15651-682: The military frontier with the Germanic tribes. In 402 AD, during a period of repeated Germanic invasions of Italy, the capital was shifted to Ravenna because nearby marshes made it more defensible, and the Adriatic provided an easy escape path by sea. When the Western Empire fell in 476 AD Ravenna became the capital of the Ostrogothic Kingdom of Italy. In the Early Middle Ages , after the Roman Empire's decline ,

15792-557: The most populous among them being Krk, Korčula and Brač. The islands along the Adriatic's western (Italian) coast are smaller and less numerous than those along the opposite coast; the best-known ones are the 117 islands on which the city of Venice is built. The northern shore of the Greek island of Corfu also lies in the Adriatic Sea as defined by the IHO. The IHO boundary places the Diapontia Islands (northwest of Corfu) in

15933-642: The name was Slavicised further as Hvar. Since the late 11th century, the Italian name of the island has been Lesina or, in Venetian , Liesena . These names appear to have their origin in the Proto-Slavic root les- , meaning "wood" or "forest". Liesena was the official name during the era of Venetian Dalmatia (16th and 17th centuries). Tourist board of City of Hvar Adriatic The Adriatic Sea ( / ˌ eɪ d r i ˈ æ t ɪ k / )

16074-492: The native bunch grasses as their forest canopy develops. The timber of European black pine is similar to that of Scots pine ( P. sylvestris ) and red pine ( P. resinosa ), being moderately hard and straight-grained. It does however tend to be rougher, softer, and not as strong, due to its faster growth. It is used for general construction, fuel, and in paper manufacture. In the United Kingdom, Pinus nigra

16215-555: The northern part of the eastern shore; Istria contained the important Roman colony at Pula and was incorporated into the province of Italy . During the Roman period, Brundisium, on the western shore, and Apollonia and Dyrrachium (originally called Epidamnos, now Durrës in Albania) on the eastern shore became important ports. Brundisium was linked by the Via Appia road to the city of Rome, and Dyrrachium and Apollonia were both on

16356-471: The northwest of Dubrovnik, adding to the Dalmatian islands as the Eurasian Plate slides over the Adriatic microplate. Furthermore, the fault causes the Apennine peninsula's southern tip to move towards the opposite shore by about 0.4 centimetres (0.16 in) per year. If this movement continues, the seafloor will be completely consumed and the Adriatic Sea closed off in 50–70 million years. In

16497-505: The organization later changed with Slovenia, Croatia and Montenegro replacing Yugoslavia. Future pollution hazards are addressed and pollution hotspots are assessed not only by nations in the basin but also through regional projects with World Bank support. 27 such hotspots have been determined as of 2011, 6 warranting an urgent response. Settlements along the Adriatic dating to between 6100 and 5900 BC appear in Albania and Dalmatia on

16638-527: The period was Mare Dalmaticum , applied to waters off the coast of Dalmatia or Illyricum . During the early modern period , the entire sea was also known as the Gulf of Venice ( Italian : golfo di Venezia ), although that name is now informally applied only to the northern area of the sea, from Maestra Point in the Po Delta to Cape Kamenjak on the Istrian Peninsula . The names for

16779-681: The present sea level, exposed during the Last Glacial Maximum . It is estimated that some karst formations are from earlier sea level drops, most notably the Messinian salinity crisis . Similarly, karst developed in Apulia from the Apulian Carbonate Platform. The largest part of the eastern coast consists of carbonate rocks, while flysch (a particular type of sedimentary rock) is significantly represented in

16920-428: The previous maritime border with Italy, but have disputed the borders between themselves. Fisheries and tourism are significant sources of income all along the Adriatic coast. Adriatic Croatia 's tourism industry has grown faster economically than the rest of the Adriatic Basin 's. Maritime transport is also a significant branch of the area's economy—there are 19 seaports in the Adriatic that each handle more than

17061-486: The region until Augustus 's general Tiberius put down the Great Illyrian Revolt , a bitter struggle waged from 6 to 9 AD. Following the repression of the revolt the Roman province of Illyricum was split into Dalmatia and Pannonia . Most of the eastern shore of the Adriatic was part of Dalmatia, except for the southernmost portion, part of the province of Macedonia , and the peninsula of Istria on

17202-446: The sea in the languages of the surrounding countries include Albanian : Deti Adriatik ; Emilian : Mèr Adriatic ; Friulian : Mâr Adriatic ; Greek : Αδριατική θάλασσα , romanized :  Adriatikí thálassa ; Istro Romanian : Marea Adriatică ; Italian : Mare Adriatico ; Serbo-Croatian : Jadransko more , Јадранско море; Slovene : Jadransko morje ; Venetian : Mar Adriàtico . In Serbo-Croatian and Slovene,

17343-518: The sea is often referred to as simply Jadran . The Adriatic Sea is a semi-enclosed sea, bordered in the southwest by the Apennine or Italian Peninsula , in the northwest by the Italian regions of Veneto and Friuli-Venezia Giulia , and in the northeast by Slovenia , Croatia , Bosnia and Herzegovina , Montenegro , and Albania —the Balkan peninsula . In the southeast, the Adriatic Sea connects to

17484-541: The semi-closed sea on larger scales. Largest of these live normally is the fin whale , and sperm whale , the largest of toothed whales also migrate but less common than fin whales, followed by Cuvier's beaked whales . Basking sharks and manta rays are some of migrant species to the sea. Historical presences of depleted or extinct species such as North Atlantic right whales (extinct or functionally extinct), Atlantic gray whales (extinct), and humpback whales have been speculated as well. Tuna has been caught by

17625-437: The slopes are necessary for the continued success of agriculture on the island. The island has a typical Mediterranean vegetation , mostly bare with woody scrub at higher, steeper elevations, turning to pine forests on the lower slopes with holm oak , Aleppo pines ( Pinus halapensis ) and black pines ( Pinus nigra dalmatica ). The islet of Šćedro is especially rich in various Mediterranean trees and plants. Hvar island

17766-660: The southeast. It is the largest Mediterranean shelf and is simultaneously a dilution basin and a site of bottom water formation. The Middle Adriatic basin is south of the Ancona–Zadar line, with the 270-metre (890 ft) deep Middle Adriatic Pit (also called the Pomo Depression or the Jabuka Pit). The 170-metre (560 ft) deep Palagruža Sill is south of the Middle Adriatic Pit, separating it from

17907-435: The southern Apennine peninsula. In addition, the Papal States were carved out in the area around Rome and central Italy in the 8th century. The High Middle Ages in the Adriatic Sea basin saw further territorial changes, including the Norman conquest of southern Italy ending the Byzantine presence on the Apennine peninsula in the 11th and 12th centuries (the territory would become the Kingdom of Naples in 1282) and

18048-406: The summer, or 12 to 14 °C (54 to 57 °F) in the winter, except along the western Adriatic coast's northern part, where it drops to 9 °C (48 °F) in the winter. The distinct seasonal temperature variations, with a longitudinal gradient in the Northern and transversal gradient in the Middle and Southern Adriatic, are attributed to the continental characteristics of the Adriatic Sea: it

18189-478: The surface and the cold and dense water mass at the bottom. The coastal currents on the opposite shore are far more complex owing to the jagged shoreline, several large islands and the proximity of the Dinaric Alps to the shore. The last produces significant temperature variations between the sea and the hinterland, which leads to the creation of local jets. The tidal movement is normally slight, usually remaining below 30 centimetres (12 in). The amphidromic point

18330-478: The territory to Hungary in 1358. In the same year, the Republic of Ragusa was established in Dubrovnik as a city-state after it was freed from Venetian suzerainty. European Black Pine Pinus nigra , the Austrian pine or black pine , is a moderately variable species of pine , occurring across Southern Europe from the Iberian Peninsula to the eastern Mediterranean, on the Anatolian peninsula of Turkey, Corsica and Cyprus, as well as Crimea and in

18471-469: The town of Izola . The thermal spring water is rich with hydrogen sulfide , has a temperature of 22 to 29.6 °C (71.6 to 85.3 °F), and has enabled the development of specific ecosystems. The inflow of freshwater, representing a third of the freshwater volume flowing into the Mediterranean, makes the Adriatic a dilution basin for the Mediterranean Sea. The Middle and South Adriatic Gyres (SAG), are significant cyclonic circulation features, with

18612-406: The valleys that are now the channels between the islands. Hvar has a typical karst landscape, which means limited or no surface water, despite adequate rainfall, which disappears quickly into crevices in the ground. Farming in such areas requires careful conservation of water and protection of the soil against erosion. The water cisterns in the fields, and the dry-stone walls, especially terracing on

18753-751: The varieties have distinct English names. It needs full sun to grow well, is intolerant of shade , and is resistant to snow and ice damage. It has naturalized in parts of the midwestern states of the United States, normally south of the normal native ranges of native pines. In Mediterranean Europe and the Anatolian Peninsula ( Asia Minor ), trees usually associated with this species include Scots pine ( Pinus sylvestris ), Serbian spruce ( Picea omorika ), Bosnian pine ( Pinus heldreichii ), Norway spruce ( Picea abies ), Taurus cedar ( Cedrus libani ), European silver fir ( Abies alba ) and related firs . Several species of juniper ( Juniperus spp.), and various broadleaf trees are associates. Pinus nigra

18894-438: The winter; and sealing wooden roofs. In the US and Canada, the European black pine is planted as a street tree, and as an ornamental tree in gardens and parks. Its value as a street tree is largely due to its resistance to salt spray (from road de-icing salt) and various industrial pollutants (including ozone ), and its intermediate drought tolerance. In the UK the tree is planted as an ornamental tree in parks and gardens. It

19035-503: The year is likewise distinct: it ranges between 38 and 39  PSUs . The southern Adriatic is subjected to saltier water from the Levantine Basin. According to the Köppen climate classification , the upper half of the Adriatic is classified as humid subtropical climate ( Cfa ), with wetter summers and colder and drier winters, and the southern Adriatic are classified as hot-summer Mediterranean climate ( Csa ) . The air temperature can fluctuate by about 20 °C (36 °F) during

19176-435: Was 4 metres (13 ft) per year. In the 12th century, the delta advanced at a rate of 25 metres (82 ft) per year. In the 17th century, the delta began to become a human-controlled environment, as the excavation of artificial channels started; the channels and new distributaries of the Po have been prograding at rates of 50 metres (160 ft) per year or more since then. There are more than 20 other rivers flowing into

19317-449: Was annexed with the fall of the Venetian Republic by the Habsburg monarchy as per the Treaty of Campo Formio . But forces of the French Empire seized it in 1806 during the Napoleonic wars before finally being taken by British marines and sailors in 1812. The Austrians regained control of the island in 1815 with the Treaty of Vienna . The beginning of the 20th century brought a period of relative prosperity. The Italian army occupied

19458-459: Was created in 2009, extending 3 nautical miles (5.6 km; 3.5 mi) into the sea and along 7 kilometres (4.3 mi) of coastline. Various zones of the protected area cover 37 square kilometres (14 sq mi) of sea surface. The Tremiti Islands reserve has been protected since 1989, while the Tremiti islands themselves are part of the Gargano National Park . The Torre Guaceto protected area, located near Brindisi and Carovigno , covers

19599-441: Was established in 1998 and covers 122 hectares (300 acres). The Debeli Rtič natural monument covers 24 hectares (59 acres), the Cape Madona natural monument covers 12 hectares (30 acres), and the Lakes in Fiesa natural monument, with the coastal lake as the only brackish lake in Slovenia, covers 2.1 hectares (5.2 acres). In 2010, Albania established its first marine protection area, the Karaburun-Sazan National Marine Park at

19740-407: Was established in 2006, and it includes 44 islands and islets, 53 square kilometres (20 sq mi) of land and 143 square kilometres (55 sq mi) of sea surface. The Mljet national park was established in 1960, covering a 24-square-kilometre (9.3 sq mi) marine protection area. In addition, there is a Ramsar wetland reserve in Croatia—the Neretva river's delta . In Slovenia,

19881-413: Was known as Mare Adriaticum ( Mare Hadriaticum , also sometimes simplified to Adria ) or, less frequently, as Mare Superum '[the] upper sea'. The two terms were not synonymous, however. Mare Adriaticum generally corresponds to the Adriatic Sea's extent, spanning from the Gulf of Venice to the Strait of Otranto. That boundary became more consistently defined by Roman authors—early Greek sources place
