An Azerbaijani official described the sea as "a burial ground ... where people die". Following the 2013 Lampedusa migrant shipwreck, the Italian government decided to strengthen the national system for the patrolling of the Mediterranean Sea by authorising " Operation Mare Nostrum", a military and humanitarian mission in order to rescue the migrants and arrest the traffickers of immigrants. In 2015, more than one million migrants crossed the Mediterranean Sea into Europe. Italy was particularly affected by the European migrant crisis. Since 2013, over 700,000 migrants have landed in Italy, mainly sub-Saharan Africans.

have converged and receded, resulting in the current tectonically active basin and its surrounding mountain chains. According to the interpretation of geologic data, there are currently several major places where Africa and Eurasia collide, causing land submergence, mountain building, and volcanism. Sediment cores drilled in 1970 and 1975 led to theories that about 6 million years ago, the Mediterranean was around below the current sea level and included arid deserts blanketed with evaporite salts. It was thought that Gibraltar's high ridges prevented Atlantic waters from entering until roughly 5.5 million years ago, when they broke through and flooded the Mediterranean. According to more recent seismic and microfossil research, the seafloor was never entirely dry. Rather approximately 5 million years ago, the seafloor was made up of many basins with varying topography and sizes, spanning in depth from . Salts were likely accumulated on the bottom of highly salinised waters of widely differing depths. The uncertainty of the timing and nature of sea-bottom salt formation and evidence from later seismic research and core samples has been the subject of intense scientific debate.

General circulation

Water circulation in the Mediterranean can be attributed to the surface waters entering from the

before exiting the Mediterranean. The surface waters entering the eastern Mediterranean Basin circulate along the Libyan and Israeli coasts. Upon reaching the Levantine Sea, the surface waters having warmed and increased its salinity from its initial Atlantic state, is now denser and sinks to form the Levantine Intermediate Waters (LIW). Most of the water found anywhere between deep in the Mediterranean originates from the LIW. LIW are formed along the coasts of Turkey and circulate westwards along the Greek and south Italian coasts. LIW are the only waters passing the Sicily Strait westwards. After the Strait of Sicily, the LIW waters circulate along the Italian, French and Spanish coasts before exiting the Mediterranean through the depths of the Strait of Gibraltar. Deep water in the Mediterranean originates from three main areas: the
Adriatic Sea The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Se ...

fueled by intense cold winds like the Bora. When new deep water is formed, the older waters mix with the overlaying intermediate waters and eventually exit the Mediterranean. The residence time of water in the Mediterranean is approximately 100 years, making the Mediterranean especially sensitive to climate change.


Other events affecting water circulation

Being a semi-enclosed basin, the Mediterranean experiences transitory events that can affect the water circulation on short time scales. 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 transitory switch in the origin of deep waters in the eastern Mediterranean was termed Eastern Mediterranean Transient (EMT) and had major consequences on water circulation of the Mediterranean. Another example of a transient event affecting the Mediterranean circulation is the periodic inversion of the North Ionian Gyre, which is an anticyclonic ocean gyre observed in the northern part of the Ionian Sea, off the Greek coast. The transition from anticyclonic to cyclonic rotation of this gyre changes the origin of the waters fueling it; when the circulation is anticyclonic (most common), the waters of the gyre originate from the Adriatic Sea. When the circulation is cyclonic, the waters originate from the Levantine Sea. These waters have different physical and chemical characteristics, and the periodic inversion of the North Ionian Gyre (called Bimodal Oscillating System or BiOS) changes the Mediterranean circulation and biogeochemistry around the Adriatic and Levantine regions.


Climate change

Because of the short residence time of its waters, the Mediterranean Sea is considered a hot-spot for climate change records, registering indeed marked increases in temperature across the entire water column since the 1950s. According to climate projections, the decrease in precipitation over the region will lead to more evaporation, ultimately increasing marine salinity. As a result of both temperature and salinity increases, the Mediterranean Sea is likely to become more stratified by the end of the 21st century, with notable consequences on water circulation and

. The stratification and warming have already led the eastern Mediterranean to become a net source of CO2 to the atmosphere notably during summer. Human-induced climate change appears to play a growing role in the development of marine heatwaves that have become a prominent subject of research in recent years, particularly in the Mediterranean where a number of areas in both western and eastern sub-basins now experience peaks of temperatures, along with more frequent, more intense, more prolonged warming events than ever seen on record. These events, mainly driven by a combination of oceanic and atmospheric factors, are often triggered by high pressure systems that will reduce cloud cover and increase solar absorption by the sea surface. Their impacts on marine ecosystems, such as mass mortality in benthic communities, coral bleaching events, disruptions in fishery catches and shifts in species distributions, can be devastating. Extreme warming can lead to

There are steep gradients in nutrient concentrations, chlorophyll concentrations and primary productivity in the Mediterranean. Nutrient concentrations in the western part of the basin are about double the concentrations in the eastern basin. The Alboran Sea, close to the Strait of Gibraltar, has a daily

of about 0.25 g C (grams of carbon) m−2 day−1 whereas the eastern basin has an average daily productivity of 0.16 g C m−2 day−1. For this reason, the eastern part of the Mediterranean Sea is termed "ultraoligotrophic". The productive areas of the Mediterranean Sea are few and small. High (i.e. more than 0.5 grams of Chlorophyll ''a'' per cubic meter) productivity occurs in coastal areas, close to the river mouths which are the primary suppliers of dissolved nutrients. The Gulf of Lion has a relatively high productivity because it is an area of high vertical mixing, bringing nutrients to the surface waters that can be used by phytoplankton to produce Chlorophyll ''a''. Primary productivity in the Mediterranean is also marked by an intense seasonal variability. In winter, the strong winds and precipitation over the basin generate vertical mixing, bringing nutrients from the deep waters to the surface, where phytoplankton can convert it into

difference virtually isolates the surface waters from the rest of the water column and nutrient exchanges are limited. As a consequence, primary productivity is very low between June and October. Oceanographic expeditions uncovered a characteristic feature of the Mediterranean Sea biogeochemistry: most of the chlorophyll production does not occur on the surface, but in sub-surface waters between 80 and 200 meters deep. Another key characteristic of the Mediterranean is its high nitrogen-to-phosphorus ratio (N:P). Redfield demonstrated that most of the world's oceans have an average N:P ratio around 16. However, the Mediterranean Sea has an average N:P between 24 and 29, which translates a widespread phosphorus limitation. Because of its low productivity, plankton assemblages in the Mediterranean Sea are dominated by small organisms such as picophytoplankton and

. Because it is a near-landlocked body of water in a normally dry climate, the Mediterranean is subject to intensive evaporation and the precipitation of evaporites. The Messinian salinity crisis started about six million years ago (mya) when the Mediterranean became landlocked, and then essentially dried up. There are salt deposits accumulated on the bottom of the basin of more than a million cubic kilometres—in some places more than three kilometres thick. Scientists estimate that the sea was last filled about 5.3 million years ago (mya) in less than two years by the Zanclean flood. Water poured in from the Atlantic Ocean through a newly breached gateway now called the Strait of Gibraltar at an estimated rate of about three orders of magnitude (one thousand times) larger than the current flow of the Amazon River.

times, as the northwest corner of Africa converged on Iberia, it lifted the Betic-Rif mountain belts across southern Iberia and northwest Africa. There the development of the intramontane Betic and Rif basins created two roughly parallel marine gateways between the Atlantic Ocean and the Mediterranean Sea. Dubbed the Betic and Rifian corridors, they gradually closed during the middle and late Miocene: perhaps several times. In the late Miocene the closure of the Betic Corridor triggered the so-called " Messinian salinity crisis" (MSC), characterised by the deposition of a thick evaporitic sequence – with salt deposits up to 2 km thick in the Levantine sea – and by a massive drop in water level in much of the Basin. This event was for long the subject of acute scientific controversy, now much appeased, regarding its sequence, geographic range, processes leading to evaporite facies and salt deposits. The start of the MSC was recently estimated astronomically at 5.96 mya, and it persisted for some 630,000 years until about 5.3 mya; see Animation: Messinian salinity crisis, at right. After the initial drawdown and re-flooding, there followed more episodes—the total number is debated—of sea drawdowns and re-floodings for the duration of the MSC. It ended when the Atlantic Ocean last re-flooded the basin—creating the Strait of Gibraltar and causing the Zanclean flood—at the end of the Miocene (5.33 mya). 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. Recent studies, however, show that repeated desiccation and re-flooding is unlikely from a geodynamic point of view.


Desiccation and exchanges of flora and fauna

The present-day Atlantic gateway, the Strait of Gibraltar, originated in the early Pliocene via the Zanclean Flood. As mentioned, there were two earlier gateways: the Betic Corridor across southern Spain and the Rifian Corridor across northern Morocco. The Betic closed about 6 mya, causing the Messinian salinity crisis (MSC); the Rifian or possibly both gateways closed during the earlier Tortonian times, causing a " Tortonian salinity crisis" (from 11.6 to 7.2 mya), long before the MSC and lasting much longer. Both "crises" resulted in broad connections between the mainlands of Africa and Europe, which allowed migrations of flora and fauna—especially large mammals including primates—between the two continents. The Vallesian crisis indicates a typical extinction and replacement of mammal species in Europe during Tortonian times following climatic upheaval and overland migrations of new species: see Animation: Messinian salinity crisis (and mammal migrations), at right. The almost complete enclosure of the Mediterranean basin has enabled the oceanic gateways to dominate seawater circulation and the environmental evolution of the sea and basin. Circulation patterns are also affected by several other factors—including climate, bathymetry, and water chemistry and temperature—which are interactive and can induce precipitation of

), and in the whole Mediterranean basin (during the MSC and the Messinian age). Many diatomites are found underneath the evaporite deposits, suggesting a connection between their formations. 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 Atlantic—so 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 the 1920s, Herman Sörgel proposed the building of a hydroelectric dam (the Atlantropa project) across the Straits, using the inflow current to provide a large amount of hydroelectric energy. The underlying energy grid was also intended to support a political union between Europe and, at least, the Maghreb part of Africa (compare Eurafrika for the later impact and Desertec for a later project with some parallels in the planned grid).

Much of these forests and shrublands have been altered beyond recognition by thousands of years of human habitation. There are now very few relatively intact natural areas in what was once a heavily wooded region.

in coastal areas, continental shelves, and decreases with depth. As a result of the drying of the sea during the Messinian salinity crisis, the marine biota of the Mediterranean is derived primarily from the Atlantic Ocean. The North Atlantic is considerably colder and more nutrient-rich than the Mediterranean, and the marine life of the Mediterranean has had to adapt to its differing conditions in the five million years since the basin was reflooded. The Alboran Sea is a transition zone between the two seas, containing a mix of Mediterranean and Atlantic species. 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. The Alboran Sea also hosts important commercial fisheries, including sardines and swordfish. The Mediterranean monk seals live in the Aegean Sea in Greece. 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. There was a resident population of orcas in the Mediterranean until the 1980s, when they went extinct, probably due to long-term PCB exposure. There are still annual sightings of orca vagrants.


Environmental issues

For 4,000 years, human activity has transformed most parts of Mediterranean Europe, and the "humanisation of the landscape" overlapped with the appearance of the present Mediterranean climate. The image of a simplistic, environmental determinist notion of a Mediterranean paradise on Earth in antiquity, which was destroyed by later civilisations, dates back to at least the 18th century and was for centuries fashionable in archaeological and historical circles. Based on a broad variety of methods, e.g. historical documents, analysis of trade relations,

as idealised by artists, poets and scientists of the early modern Enlightenment. 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. For example, some of the deforestation had already taken place before the Roman age. While in the Roman age large enterprises such as the latifundia took effective care of forests and agriculture, the largest depopulation effects came with the end of the empire. Some assume that the major deforestation took place in modern times—the later usage patterns were also quite different e.g. in southern and northern Italy. Also, the climate has usually been unstable and there is evidence of various ancient and modern " Little Ice Ages", and plant cover accommodated to various extremes and became resilient to various patterns of human activity. Even Grove considered that human activity could be the cause of climate change. Modern science has been able to provide clear evidence of this. The wide ecological diversity typical of Mediterranean Europe is predominantly based on human behaviour, as it is and has been closely related to human usage patterns. The diversity range was enhanced by the widespread exchange and interaction of the longstanding and highly diverse local agriculture, intense transport and trade relations, and the interaction with settlements, pasture and other land use. The greatest human-induced changes, however, came after

Natural hazards

The Mediterranean region is one of the most geologically active maritime area of the globe, sitting on a complex tectonic boundary zone between the European and African plates. The geology of the region, with the presence of plate boundaries and active faults, makes it prone to quite frequent earthquakes, tsunamis and submarine landslides with can have devastating consequences in densely populated coastal areas. In addition climate change now intensifies the frequency and impacts of storm surges and coastal flooding, putting additional human lives and property at risk. Earthquakes are relatively frequent in the Mediterranean Basin, ranking among the most damaging geohazards. One of the most destructive was the Crete earthquake in 365 BC, with Mw > 8, which lifted the western tip of the island by up to 9 m and caused a mega tsunami that destroyed many harbors in the eastern sub-basin. Volcanic eruptions are not uncommon either and left their mark in historical and archaeological records. The largest include the Thera eruption, dated around 1600 BC, and the eruptions of

. In the same region the Phlegraean Fields west of Naples constitute one of the most significant volcanic systems in the world, still very active. In the same general area, volcanoes like Mt. Etna and Stromboli are considered in a state of permanent activity, with frequent eruptions and lava emissions through the past 1500 years. Tsunamis, usually triggered by earthquakes, volcanic eruptions and submarine landslides, have caused a number of documented disasters in the Mediterranean Basin in the past 2500 years. Historical examples include the 365 and 1303 tsunamis in the Hellenic Arc, more recently the disastrous 1908 event that destroyed the cities of Messina and Reggio Calabria, and the large tsunami that occurred off the Algerian margin in 2003. On the diplomatic front, the experience of coastal countries and regional authorities is leading to exchange at the international level with the cooperation of NGOs, states, regional and municipal authorities. The Greek–Turkish earthquake diplomacy is a quite positive example of natural hazards leading to improved relations between traditional rivals in the region after earthquakes in İzmit and Athens in 1999. The European Union Solidarity Fund (EUSF) was set up to respond to major natural disasters and express European solidarity to disaster-stricken regions within all of Europe. The largest amount of funding requests in the EU relates to

, so the canal functions as a tidal strait that pours Red Sea water into the Mediterranean. The Bitter Lakes, which are hyper-saline natural lakes that form part of the canal, blocked the migration of Red Sea species into the Mediterranean for many decades, but as the salinity of the lakes gradually equalised with that of the Red Sea, the barrier to migration was removed, and plants and animals from the Red Sea have begun to colonise the Eastern Mediterranean. The Red Sea is generally saltier and more nutrient-poor than the Atlantic, so the Red Sea species have advantages over Atlantic species in the salty and nutrient-poor Eastern Mediterranean. Accordingly, Red Sea species invade the Mediterranean biota, and not vice versa; this phenomenon is known as the Lessepsian migration (after Ferdinand de Lesseps, the French engineer) or Erythrean ("red") invasion.

terminologies, they are alien species, as they are non-native (non-indigenous) to the Mediterranean Sea, and are found outside their normal, non-adjacent area of distribution. 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. In the context of CBD, "introduction" refers to the movement by human agency, indirect or direct, of an alien species outside of its natural range (past or present). The Suez Canal, being an artificial (human-made) canal, is a human agency. Lessepsian migrants are therefore "introduced" species (indirect, and unintentional). Whatever wording is chosen, they represent a threat to the native Mediterranean biodiversity, because they are non-indigenous to this sea. In recent years, the Egyptian government's announcement of its intentions to deepen and widen the Canal raised concerns from marine biologists, fearing that such an act will only worsen the invasion of Red Sea species into the Mediterranean, and lead to even more species passing through the Canal.


Arrival of new tropical Atlantic species

In recent decades, the arrival of exotic species from the tropical Atlantic has become noticeable. In many cases this reflects an expansion – favoured by a warming trend of sub-tropical Atlantic waters, and also by a fast-growing maritime traffic – of the natural range of species that now enter the Mediterranean through the Strait of Gibraltar. While not as intense as Lessepsian migration, the process is of importance and is therefore receiving increased levels of scientific coverage.

Tourism

The coast of the Mediterranean has been used for tourism since ancient times, as the Roman villa buildings on the Amalfi Coast or in Barcola show. From the end of the 19th century, in particular, the beaches became places of longing for many Europeans and travellers. From then on, and especially after World War II, mass tourism to the Mediterranean began with all its advantages and disadvantages. While initially, the journey was by train and later by bus or car, today the plane is increasingly used. Tourism is today one of the most important sources of income for many Mediterranean countries, despite the human-made geopolitical conflicts in the region. The countries have tried to extinguish rising human-made chaotic zones that might affect the region's economies and societies in neighbouring coastal countries, and shipping routes. Naval and rescue components in the Mediterranean Sea are considered to be among the best due to the rapid cooperation between various naval fleets. Unlike the vast open oceans, the sea's closed position facilitates effective naval and rescue missions, considered the safest and regardless of any human-made or

. Tourism is a source of income for small coastal communities, including islands, independent of urban centres. However, tourism has also played a major role in the degradation of the coastal and marine environment. Rapid development has been encouraged by Mediterranean governments to support the large numbers of tourists visiting the region, but this has caused serious disturbance to marine habitats by erosion and

Overfishing

Fish stock levels in the Mediterranean Sea are alarmingly low. The European Environment Agency says that more than 65% of all fish stocks in the region are outside safe biological limits and the United Nations Food and Agriculture Organisation, that some of the most important fisheries—such as albacore and bluefin tuna, hake, marlin, swordfish, red mullet and sea bream—are threatened. There are clear indications that catch size and quality have declined, often dramatically, and in many areas, larger and longer-lived species have disappeared entirely from commercial catches. Large open-water fish like tuna have been a shared fisheries resource for thousands of years, but the stocks are now dangerously low. In 1999,

published a report revealing that the amount of bluefin tuna in the Mediterranean had decreased by over 80% in the previous 20 years, and government scientists warn that without immediate action, the stock will collapse.


Marine heatwaves

A study showed that climate change-related exceptional marine heatwaves in the Mediterranean Sea during 2015–2019 resulted in widespread mass sealife die-offs in five consecutive years.
