how deep is the mediterranean sea

Europe started to revive, however, as more organized and centralized states began to form in the later Middle Ages after the Renaissance of the 12th century. [22] According to Robert Davis, from the 16th to 19th centuries, pirates captured 1million to 1.25million Europeans as slaves. The end of the Miocene also marked a change in the climate of the Mediterranean basin. Summary and overview of the CYCLOPS P addition Lagrangian experiment in the Eastern Mediterranean. (2008). By 2100 the overall level of the Mediterranean could rise between 3 and 61cm (1.2 and 24.0in) as a result of the effects of climate change. [103], The Mediterranean Sea has an average depth of 1,500m (4,900ft) and the deepest recorded point is 5,267m (17,280ft) in the Calypso Deep in the Ionian Sea. The countries have tried to extinguish rising human-made chaotic zones[clarification needed] that might affect the region's economies and societies in neighbouring coastal countries, and shipping routes. Bosc, E., Bricaud, A., and Antoine, D. (2004). None of that stops marine life, pollution and human expeditions. It is estimated that there are more than 17,000 marine species in the Mediterranean Sea with generally higher marine biodiversity in coastal areas, continental shelves, and decreases with depth.[116]. There the development of the intramontane Betic and Rif basins created two roughly parallel marine gateways between the Atlantic Ocean and the Mediterranean Sea. The Suez Canal connects the Mediterranean Sea to the Red Sea, making it the shortest maritime route to Asia from Europe. Since the Mediterranean is subject to the deposition of eolian dust from the Sahara during dry periods, whereas riverine detrital input prevails during wet ones, the Mediterranean marine sapropel-bearing sequences provide high-resolution climatic information. Lessepsian migrants are therefore "introduced" species (indirect, and unintentional). [148][149], The beach of la Courtade in the les d'Hyres, France, A view of Raouch off the coast of Beirut, Lebanon, Sunset at the Deir al-Balah beach, Gaza Strip, Coast of Alexandria, view From Bibliotheca Alexandrina, Egypt, "Mediterranean" redirects here. Large open-water fish like tuna have been a shared fisheries resource for thousands of years but the stocks are now dangerously low. In general, the water of this layer is homogeneous. The Mediterranean Sea is commonly referred to as an LNLC (Low-Nutrient, Low-Chlorophyll) area. The westernmost point of the Mediterranean is located at the transition from the Alborn Sea to the Strait of Gibraltar, the easternmost point is on the coast of the Gulf of Iskenderun in southeastern Turkey. It lies between latitudes 30 and 46 N and longitudes 6 W and 36 E. Aegean Sea, Greek Aigaon Plagos, Turkish Ege Deniz, an arm of the Mediterranean Sea located between the Greek peninsula on the west and Asia Minor on the east. Total annual precipitation is significantly higher on the European part of the Mediterranean basin, especially near the Alps (the 'water tower of Europe') and other high mountain ranges. Tourism is a source of income for small coastal communities, including islands, independent of urban centres. Lebeaupin Brossier, C., Branger, K., Deltel, C., and Drobinski, P. (2011). There are salt deposits accumulated on the bottom of the basin of more than a million cubic kilometresin some places more than three kilometres thick. Underwater calcarenite ridges (with hard substrate) are particularly common in northern Israel continental shelf up to a depth of approximately 40 m. Contents show 1 How deep is the bottom of the Mediterranean Some research has suggested that a desiccation-flooding-desiccation cycle may have repeated several times, which could explain several events of large amounts of salt deposition. The Suez Canal, being an artificial (human-made) canal, is a human agency. With the opening of the lockless Suez Canal in 1869, the flow of trade between Europe and Asia changed fundamentally. pp. As a consequence, the river discharges of the Rhne and Po are similar to that of the Nile, despite the latter having a much larger basin. While initially, the journey was by train and later by bus or car, today the plane is increasingly used. Ionian Sea - WorldAtlas [133] This could have adverse effects on populations across the Mediterranean: Coastal ecosystems also appear to be threatened by sea level rise, especially enclosed seas such as the Baltic, the Mediterranean and the Black Sea. The Major Subdivisions Of The Mediterranean Sea - WorldAtlas [125] It is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii and Herculaneum. (2005). When these species succeed in establishing populations in the Mediterranean Sea, compete with and begin to replace native species they are "Alien Invasive Species", as they are an agent of change and a threat to the native biodiversity. The Mediterranean Sea has an average depth of 1,500 m (4,900 ft) and the deepest recorded point is 5,109 m (16,762 ft) 1 m (3 ft) in the Calypso Deep in the Ionian Sea. How Deep is the Mediterranean Sea? - AZ Animals The sea is also notable for being one of the world's most seismically active areas. The Pacific Ocean is the world's largest and deepest ocean. The Alboran Sea has the largest population of bottlenose dolphins in the Western Mediterranean, is home to the last population of harbour porpoises in the Mediterranean and is the most important feeding grounds for loggerhead sea turtles in Europe. Other Arabic names were Bar al-m() ( ) ("the Sea of Syria") and Bar al-Maghrib () ("the Sea of the West"). It does not recognize the label Sea of Sardinia.[38]. Sea Of Crete - WorldAtlas How deep is the ocean? - The Conversation Unlike the vast multidirectional ocean currents in open oceans within their respective oceanic zones; biodiversity in the Mediterranean Sea is that of a stable one due to the subtle but strong locked nature of currents which affects favourably, even the smallest macroscopic type of volcanic life form. This strong summer degassing, combined with the prolonged and pronounced stratification results in the formation of aragonite crystals abiotically in the water column. Note 2: Thracian Sea and Myrtoan Sea are seas that are part of the Aegean Sea. Because of its latitude and its landlocked position, the Mediterranean is especially sensitive to astronomically induced climatic variations, which are well documented in its sedimentary record. [119] Among further current important threats to Mediterranean landscapes are overdevelopment of coastal areas, abandonment of mountains and, as mentioned, the loss of variety via the reduction of traditional agricultural occupations. The following countries are in the Mediterranean drainage basin while not having a coastline on the Mediterranean Sea: The following countries have a coastline on the Mediterranean Sea: Several other territories also border the Mediterranean Sea (from west to east): Exclusive economic zones in Mediterranean Sea:[50][51], The Coastline length is about 46,000km.[52][53][54]. In the ocean's deepest zones, many life forms have adapted to live in the dark under crushing .

Mediterranean Sea - Geology, Climate, Biodiversity | Britannica Many diatomites are found underneath the evaporite deposits, suggesting a connection between their[clarification needed] formations. Introduction to the Biogeochemistry from the Oligo- trophic to the Ultraoligotrophic Mediterranean (BOUM) experiment. Mediterranean Sea - WorldAtlas Global Biogeochemical Cycles, 26(2). Whatever wording is chosen, they represent a threat to the native Mediterranean biodiversity, because they are non-indigenous to this sea. The Mediterranean Sea: Cradle of Civilization | United Nations In the mid-1990s, the Aegean Sea became the main area for deep water formation in the eastern Mediterranean after particularly cold winter conditions. This was the last naval battle to be fought primarily between galleys. On the impact of the Bimodal Oscillating System (BiOS) on the biogeochemistry and biology of the Adriatic and Ionian Seas (Eastern Mediterranean). [92] However, in winter, light may be the limiting factor for primary productivity. Global Biogeochemical Cycles, 26(2). The deepest known spot in the ocean is devoid of light, exceeds 6.5 miles deep and packs 1,000 times the pressure of dry land. Dubbed the Betic and Rifian corridors, they gradually closed during the middle and late Miocene: perhaps several times. Natural divisions A submarine ridge between the island of Sicily and the African coast with a sill depth of about 1,200 feet (365 metres) divides the Mediterranean Sea into western and eastern parts. [70] The average salinity in the basin is 38 PSU at 5 m depth. [13] The origin of the name is not clear, as it is not known in earlier Greek, Byzantine or Islamic sources. Crops of the region include olives, grapes, oranges, tangerines, carobs and cork. [106] In the late Miocene the closure of the Betic Corridor triggered the so-called "Messinian salinity crisis" (MSC), characterized by the deposition of a thick evaporitic sequence with salt deposits up to 2km thick in the Levantine sea and by a massive drop in water level in much of the Basin. The Mediterranean Sea was formed by the most spectacular flood in Earth's history when water from the Atlantic Ocean breached the mountain range joining Europe and Africa with the force of a. Unlike the vast open oceans, the sea's closed position facilitates effective naval and rescue missions[citation needed], considered the safest[citation needed] and regardless of[clarification needed] any human-made or natural disaster.[147]. The Mediterranean Sea receives from the rivers that flow into it only about one-third of the amount of water that it loses by evaporation. What Has Been Found in the Deep Waters of the Mariana Trench? The history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. [119], The historical evolution of climate, vegetation and landscape in southern Europe from prehistoric times to the present is much more complex and underwent various changes. Mediterranean Sea Ibiza Mediterranean Sea, an intercontinental sea that stretches from the Atlantic Ocean on the west to Asia on the east and separates Europe from Africa. Invasive species have become a major component of the Mediterranean ecosystem and have serious impacts on the Mediterranean ecology, endangering a number of local and endemic Mediterranean species. For other uses, see, A satellite image showing the Mediterranean Sea. The Sea of Crete is often referred to as the Cretan Sea or the Sea of Candia. Mediterranean Sea - Wikipedia Krom, M. D., Thingstad, T. F., Brenner, S., Carbo, P., Drakopoulos, P., Fileman, T. W., Flaten, G. A. F., Groom, S., Herut, B., Kitidis, V., Kress, N., Law, C. S., Liddicoat, M. I., Mantoura, R. F.

S., Zodiatis, G., and Zohary, T. (2005). This resulted in more uniform, large-scale formations[of what?]. Large islands in the Med include Cyprus, Crete, Rhodes . Around 1200 BC the eastern Mediterranean was greatly affected by the Bronze Age Collapse, which resulted in the destruction of many cities and trade routes. Calypso Deep is the deepest part of the Mediterranean Sea, located in the Hellenic Trench, Ionian Sea, 62.6 km south-west of Pylos, Greece, with a maximum depth of 5,109 m (16,762 ft). Geography The Ligurian Sea has a depth of about 2,850 m at its deepest point, located northwest of Corsica island. As the naval prowess of the European powers increased, they confronted Ottoman expansion in the region when the Battle of Lepanto (1571) checked the power of the Ottoman Navy. The Viking raids further disrupted the trade in western Europe and brought it to a halt. That would explain the Bulgarian Byalo More, the Turkish Akdeniz, and the Arab nomenclature described above, lit. Today, evaporation of surface seawater (output) is more than the supply (input) of fresh water by precipitation and coastal drainage systems, causing the salinity of the Mediterranean to be much higher than that of the Atlanticso much so that the saltier Mediterranean waters sink below the waters incoming from the Atlantic, causing a two-layer flow across the Strait of Gibraltar: that is, an outflow submarine current of warm saline Mediterranean water, counterbalanced by an inflow surface current of less saline cold oceanic water from the Atlantic. In 2003, the World Wildlife Fund raised concerns about the widespread drift net fishing endangering populations of dolphins, turtles, and other marine animals such as the spiny squat lobster. [72] Without this Atlantic water, the sea level of the Mediterranean Sea would fall at a rate of about 1 m per year. The Alboran Sea is a transition zone between the two seas, containing a mix of Mediterranean and Atlantic species. The Mediterranean has played a central role in the history of Western civilization. Suez Canal | History, Map, Importance, Length, Depth, & Facts [119] The belief stems more from the failure of the recent landscape to measure up to the imaginary past of the classics as idealised by artists, poets and scientists of the early modern Enlightenment. The most-recent estimate of the average ocean depth of 3,682 meters (12,080 feet) was calculated in 2010 by scientists from NOAA and Woods Hole Oceanographic Institution using satellite measurements. Twenty-two countries border the Mediterranean Sea. The construction of the Aswan High Dam across the Nile River in the 1960s reduced the inflow of freshwater and nutrient-rich silt from the Nile into the Eastern Mediterranean, making conditions there even more like the Red Sea and worsening the impact of the invasive species. The impacts of some Lessepsian species have proven to be considerable, mainly in the Levantine basin of the Mediterranean, where they are replacing native species and becoming a familiar sight. Consists of gulfs, straits, channels and other parts that do not have the name of a specific sea. . Many rivers that originate in the Apennine Mountains drain into the Ligurian Sea.
