42° N. w. 51° east d. HGIOLCaspian Sea- the largest closed body of water on Earth, which can be classified as the largest closed lake, or as a full-fledged sea, due to its size, and also because its bed is composed of oceanic-type crust. Located at the junction of Europe and Asia. The water in the Caspian Sea is brackish, from 0.05 ‰ near the mouth of the Volga to 11-13 ‰ in the southeast. The water level is subject to fluctuations, according to 2009 data it was 27.16 m below sea level. The area of the Caspian Sea is currently approximately 371,000 km², the maximum depth is 1025 m.

Etymology
Geographical location
The Caspian Sea is located at the junction of Europe and Asia. The length of the sea from north to south is approximately 1200 kilometers (36°34"-47°13" N), from west to east - from 195 to 435 kilometers, on average 310-320 kilometers (46°-56° in .d.).
According to physical and geographical conditions, the Caspian Sea is conventionally divided into three parts - the Northern Caspian (25% of the sea area), the Middle Caspian (36%) and the Southern Caspian (39%). The conditional border between the Northern and Middle Caspian runs along the line Chechen Island - Cape Tyub-Karagan, between the Middle and Southern Caspian - along the line Chilov Island - Cape Gan-Gulu.
Coast
The territory adjacent to the Caspian Sea is called the Caspian region.
Peninsulas
- Absheron Peninsula, located on the western coast of the Caspian Sea on the territory of Azerbaijan, at the northeastern end of the Greater Caucasus, on its territory the cities of Baku and Sumgait are located
- Mangyshlak, located on the eastern coast of the Caspian Sea, on the territory of Kazakhstan, on its territory is the city of Aktau
Islands
There are about 50 large and medium-sized islands in the Caspian Sea with a total area of approximately 350 square kilometers.
Largest islands:

Kara-Bogaz-Gol
Off the east coast is salt lake Kara-Bogaz-Gol, until 1980, was a bay-lagoon of the Caspian Sea, connected to it by a narrow strait. In 1980, a dam was built separating Kara-Bogaz-Gol from the Caspian Sea, and in 1984 a culvert was built, after which the level of Kara-Bogaz-Gol dropped by several meters. In 1992, the strait was restored, through which water flows from the Caspian Sea to Kara-Bogaz-Gol and evaporates there. Every year, 8-10 cubic kilometers of water (according to other sources - 25 cubic kilometers) and about 15 million tons of salt flow into Kara-Bogaz-Gol from the Caspian Sea.
Rivers flowing into the Caspian Sea
130 rivers flow into the Caspian Sea, of which 9 rivers have a delta-shaped mouth. Large rivers flowing into the Caspian Sea are Volga, Terek, Sulak, Samur (Russia), Ural, Emba (Kazakhstan), Kura (Azerbaijan), Atrek (Turkmenistan), Sefidrud (Iran). Largest river, flowing into the Caspian Sea - the Volga, its average annual flow is 215-224 cubic kilometers. The Volga, Ural, Terek, Sulak and Emba provide up to 88-90% of the annual flow into the Caspian Sea.
Basin of the Caspian Sea
Coastal states
According to the Intergovernmental Economic Conference of the Caspian States:
The Caspian Sea washes the shores of five coastal states:
Cities on the Caspian Sea coast
On the Russian coast there are cities - Lagan, Makhachkala, Kaspiysk, Izberbash, Dagestan Lights and the most southern city Russia Derbent. port city The Caspian Sea is also considered Astrakhan, which, however, is not located on the shores of the Caspian Sea, but in the Volga delta, 60 kilometers from north coast Caspian Sea.
Physiography
Area, depth, volume of water
The area and volume of water in the Caspian Sea varies significantly depending on fluctuations in water levels. At a water level of −26.75 m, the area is approximately 371,000 square kilometers, the volume of water is 78,648 cubic kilometers, which is approximately 44% of the world's lake water reserves. The maximum depth of the Caspian Sea is in the South Caspian depression, 1025 meters from its surface level. In terms of maximum depth, the Caspian Sea is second only to Baikal (1620 m) and Tanganyika (1435 m). The average depth of the Caspian Sea, calculated from the bathygraphic curve, is 208 meters. At the same time, the northern part of the Caspian Sea is shallow, its maximum depth does not exceed 25 meters, and the average depth is 4 meters.
Water level fluctuations
Flora
The flora of the Caspian Sea and its coast is represented by 728 species. The predominant plants in the Caspian Sea are algae - blue-green, diatoms, red, brown, characeae and others, and flowering plants - zoster and ruppia. In origin, the flora is predominantly of Neogene age, however, some plants were brought into the Caspian Sea by humans deliberately, or on the bottoms of ships.
Story
Origin
The Caspian Sea is of oceanic origin - its bed is composed of oceanic-type crust. 13 million l. n. the resulting Alps separated the Sarmatian Sea from the Mediterranean. 3.4 - 1.8 million l. n. (Pliocene) there was the Akchagyl Sea, the sediments of which were studied by N. I. Andrusov. It was originally formed on the site of the dried-up Pontic Sea, from which Lake Balakhanskoe (in the southern Caspian Sea) remained. The Akchagyl transgression gave way to the Domashkin regression (a drop of 20 - 40 m from the level of the Akchagyl basin), accompanied by a strong desalination of sea waters, which is due to the cessation of the flow of sea (ocean) waters from the outside. After a short Domashkin regression at the beginning of the Quaternary period (Eopleistocene), the Caspian Sea is almost restored in the form of the Absheron Sea, which covers the Caspian Sea and floods the territories of Turkmenistan and the Lower Volga region. At the beginning of the Absheron transgression, the basin turns into a brackish water body. The Absheron Sea exists from 1.7 to 1 million years ago. The beginning of the Pleistocene in the Caspian Sea was marked by a long and deep Turkic regression (-150 m to −200 m), corresponding to the Matuyama-Brunhes magnetic reversal (0.8 million years ago). The water mass of the Turkian basin with an area of 208 thousand km² was concentrated in the South Caspian and part of the Middle Caspian basins, between which there was a shallow strait in the area of the Absheron threshold. In the early Neopleistocene, after the Turkic regression, there existed an isolated Early Baku and a Late Baku (level up to 20 m) drainage basins (approx. 400 thousand years ago). The Vened (Mishovdag) regression divided the Baku and Urundzhik (middle Neopleistocene, up to −15 m) transgressions at the end of the early - beginning of the late Pleistocene (basin area - 336 thousand km²). Between the marine Urundzhik and Khazar deposits, a large deep Cheleken regression (up to −20 m) was noted, corresponding to the optimum of the Likhvin interglacial (350-300 thousand years ago). In the Middle Neopleistocene there were basins: early Khazar (200 thousand years ago), early Khazar middle (level up to 35-40 m) and early Khazar late. In the late Neopleistocene, there was an isolated late Khazar basin (level up to −10 m, 100 thousand years ago), after which a small Chernoyarsk regression occurred in the second half - the end of the Middle Pleistocene (thermoluminescent dates 122-184 thousand years ago), in in turn, replaced by the Hyrcanian (Gyurgyan) basin.
The deep long-term Atelian regression of the mid-Late Pleistocene at the initial stage had a level of −20 - −25 m, at the maximum stage −100 - −120 m, at the third stage - −45 - −50 m. At the maximum, the basin area is reduced to 228 thousand km² . After Atel regression (−120 - −140 m), approx. 17 thousand l. n. The early Khvalynian transgression began - up to + 50 m (the Manych-Kerch Strait was functioning), which was interrupted by the Eltonian regression. The Early Khvalynsky II basin (level up to 50 m) was replaced at the beginning of the Holocene by a short-term Enotayev regression (from −45 to −110 m), coinciding in time with the end of the Preboreal and the beginning of the Boreal. The Enotayevskaya regression gave way to the Late Khvalynskaya transgression (0 m). The Late Khvalynian transgression was replaced in the Holocene (ca. 9-7 thousand years ago or 7.2-6.4 thousand years ago) by the Mangyshlak regression (from −50 to −90 m). The Mangyshlak regression gave way during the first phase of interglacial cooling and humidification (Atlantic period) to the New Caspian transgression. The New Caspian basin was brackish-water (11-13 ‰), warm-water and isolated (level up to −19 m). At least three cycles of transgressive-regressive phases have been recorded in the development of the Novo-Caspian basin. The Dagestan (Gousan) transgression previously belonged to the initial stage of the New Caspian era, however, the absence of a leading New Caspian form in its sediments Cerastoderma glaucum (Cardium edule) gives grounds for identifying it as an independent transgression of the Caspian Sea. The Izberbash regression, separating the Dagestan and the Neo-Caspian transgressions of the Caspian Sea itself, occurred between 4.3 and 3.9 thousand years ago. Judging by the structure of the Turali section (Dagestan) and radiocarbon analysis data, transgressions were noted twice - about 1900 and 1700 years ago.
Anthropological and cultural history of the Caspian Sea
Shipping
Shipping is developed in the Caspian Sea. On the Caspian Sea there are ferry crossings, in particular, Baku - Turkmenbashi, Baku - Aktau, Makhachkala - Aktau. The Caspian Sea has a shipping connection with the Sea of Azov through the Volga, Don and Volga-Don Canal rivers.
Fishing and seafood production
Fishing (sturgeon, bream, carp, pike perch, sprat), caviar production, as well as seal fishing. More than 90 percent of the world's sturgeon catch occurs in the Caspian Sea. In addition to industrial mining, illegal mining of sturgeon and their caviar flourishes in the Caspian Sea.
Recreational resources
Natural environment of the Caspian coast with sandy beaches, mineral waters and healing mud in the coastal zone creates good conditions for relaxation and treatment. At the same time, according to the degree of development of resorts and the tourism industry Caspian coast noticeably loses to the Black Sea coast of the Caucasus. At the same time, in recent years The tourism industry is actively developing on the coasts of Azerbaijan, Iran, Turkmenistan and Russian Dagestan. Azerbaijan is actively developing resort area in the Baku region. At the moment, a world-class resort has been created in Amburan, another modern tourist complex is being built in the area of the village of Nardaran, and holidays in the sanatoriums of the villages of Bilgah and Zagulba are very popular. A resort area is also being developed in Nabran, in northern Azerbaijan. However, high prices, a generally low level of service and a lack of advertising lead to the fact that there are almost no foreign tourists at the Caspian resorts. The development of the tourism industry in Turkmenistan is hampered by a long-term policy of isolation, in Iran - by Sharia laws, due to which mass holidays of foreign tourists on the Caspian coast of Iran are impossible.
Environmental issues
Environmental issues The Caspian Sea is associated with water pollution as a result of oil production and transportation on the continental shelf, the flow of pollutants from the Volga and other rivers flowing into the Caspian Sea, the life of coastal cities, as well as the flooding of individual objects due to rising levels of the Caspian Sea. Predatory production of sturgeon and their caviar, rampant poaching lead to a decrease in the number of sturgeon and to forced restrictions on their production and export.
Legal status
After the collapse of the USSR, the division of the Caspian Sea has long been and still remains the subject of unresolved disagreements related to the division of Caspian shelf resources - oil and gas, as well as biological resources. For a long time, negotiations were ongoing between the Caspian states on the status of the Caspian Sea - Azerbaijan, Kazakhstan and Turkmenistan insisted on dividing the Caspian along the median line, Iran insisted on dividing the Caspian by one-fifth between all Caspian states.
In relation to the Caspian Sea, the key is the physical-geographical circumstance that it is a closed inland body of water that does not have a natural connection with the World Ocean. Accordingly, the norms and concepts of international maritime law, in particular, the provisions of the 1982 UN Convention on the Law of the Sea, should not automatically apply to the Caspian Sea. Based on this, in relation to the Caspian Sea it would be unlawful to apply such concepts as “territorial sea”, “exclusive economic zone”, “continental shelf”, etc.
The current legal regime of the Caspian Sea was established by the Soviet-Iranian treaties of 1921 and 1940. These treaties provide for freedom of navigation throughout the sea, freedom of fishing with the exception of ten-mile national fishing zones and a ban on vessels flying the flag of non-Caspian states sailing in its waters.
Negotiations on the legal status of the Caspian Sea are currently ongoing.
Delineation of sections of the Caspian seabed for subsoil use
The Russian Federation concluded an agreement with Kazakhstan on delimiting the bottom of the northern part of the Caspian Sea in order to exercise sovereign rights to subsoil use (dated July 6, 1998 and the Protocol thereto dated May 13, 2002), an agreement with Azerbaijan on delimiting adjacent areas of the bottom of the northern part of the Caspian Sea (dated September 23, 2002), as well as the trilateral Russian-Azerbaijani-Kazakh agreement on the junction point of the demarcation lines of adjacent sections of the Caspian Sea bottom (dated May 14, 2003), which established geographical coordinates dividing lines limiting the areas of the seabed within which the parties exercise their sovereign rights in the field of exploration and production of mineral resources.
The Caspian Sea is the largest endorheic lake on Earth, located at the junction of Europe and Asia, called a sea due to the fact that its bed is composed of oceanic-type crust. The Caspian Sea is an endorheic lake, and the water in it is salty, from 0.05 ‰ near the mouth of the Volga to 11-13 ‰ in the southeast. The water level is subject to fluctuations, according to 2009 data it was 27.16 m below sea level. The Caspian Sea is located at the junction of two parts of the Eurasian continent - Europe and Asia. The length of the Caspian Sea from north to south is approximately 1200 kilometers, from west to east - from 195 to 435 kilometers, on average 310-320 kilometers. The Caspian Sea is conventionally divided according to physical and geographical conditions into 3 parts - the Northern Caspian, the Middle Caspian and the Southern Caspian. The conditional border between the Northern and Middle Caspian runs along the line of the island. Chechen - Cape Tyub-Karagansky, between the Middle and Southern Caspian Sea - along the line of the island. Residential - Cape Gan-Gulu. The area of the Northern, Middle and Southern Caspian Sea is 25, 36, 39 percent, respectively.
The length of the coastline of the Caspian Sea is estimated at approximately 6500-6700 kilometers, with islands - up to 7000 kilometers. The shores of the Caspian Sea in most of its territory are low-lying and smooth. In the northern part coastline indented by water channels and islands of the Volga and Ural deltas, the banks are low and swampy, and the water surface in many places is covered with thickets. The east coast is dominated by limestone shores adjacent to semi-deserts and deserts. The most winding shores are on the western coast in the area of the Absheron Peninsula and on the eastern coast in the area of the Kazakh Gulf and Kara-Bogaz-Gol. The territory adjacent to the Caspian Sea is called the Caspian region.
Is it correct to call the Caspian Sea a sea?
It is known that the sea is part of the World Ocean. From this geographically correct point of view, the Caspian Sea cannot in any way be considered a sea, since it is separated from the ocean by huge land masses. The shortest distance from the Caspian Sea to the Black Sea, the closest of the seas included in the World Ocean system, is 500 kilometers. Therefore, it would be more correct to talk about the Caspian Sea as a lake. This largest lake in the world is often called simply the Caspian or lake-sea.
The Caspian Sea has a number of characteristics of a sea: its water is salty (however, there are other salty lakes), its area is not much inferior to the area of such seas as the Black, Baltic, Red, Northern and even exceeds the area of the Azov and some others (however, the Canadian Lake Superior also has a huge area , like the three Seas of Azov). In the Caspian Sea there are often fierce storm winds and huge waves (and this is not uncommon on Lake Baikal).
So, after all, the Caspian Sea is a lake? Here we go Wikipedia says it And the Great Soviet Encyclopedia answers that no one has yet been able to give an exact definition of this issue - “There is no generally accepted classification.”
Do you know why this is very important and fundamental? And here's why...
The lake belongs to internal waters - the sovereign territories of coastal states, to which the international regime does not apply (the UN principle of non-interference in the internal affairs of states). But the sea area is divided differently, and the rights of coastal states here are completely different.
Due to its geographical location, the Caspian Sea itself, unlike the land territories surrounding it, has not been the object of any targeted attention from the coastal states for many centuries. Only at the beginning of the 19th century. the first treaties were concluded between Russia and Persia: Gulistan (1813) 4 and Turkmanchay (1828), summing up the results of the Russian-Persian war, as a result of which Russia annexed a number of Transcaucasian territories and received the exclusive right to maintain a military fleet in the Caspian sea. Russian and Persian merchants were allowed to trade freely on the territory of both states and use the Caspian Sea to transport goods. The Turkmanchay Treaty confirmed all these provisions and became the basis for maintaining international relations between the parties until 1917.
After the October Revolution of 1917, in a note dated January 14, 1918, the new Russian government that came to power renounced its exclusive military presence in the Caspian Sea. The treaty between the RSFSR and Persia of February 26, 1921 declared invalid all agreements concluded before it by the tsarist government. The Caspian Sea became a body of water for the common use of the parties: both states were granted equal rights of free navigation, with the exception of cases when the crews of Iranian ships could include citizens of third countries using the service for unfriendly purposes (Article 7). The 1921 agreement did not provide for a maritime border between the parties.
In August 1935, the following agreement was signed, the parties to which were new subjects of international law - the Soviet Union and Iran, which acted under a new name. The parties confirmed the provisions of the 1921 agreement, but introduced into the agreement a new concept for the Caspian Sea - a 10-mile fishing zone, which limited the spatial limits of this fishery for its participants. This was done in order to control and preserve the living resources of the reservoir.
In the context of the outbreak of World War II, unleashed by Germany, an urgent need arose to conclude a new agreement between the USSR and Iran on trade and navigation in the Caspian Sea. The reason for this was the concern of the Soviet side, caused by Germany's interest in intensifying its trade ties with Iran and the danger of using the Caspian Sea as one of the stages of the transit route. The agreement between the USSR and Iran 10 signed in 1940 protected the Caspian Sea from such a prospect: it repeated the main provisions of previous agreements, which provided for the presence of ships of only these two Caspian states in its waters. It also included a provision for its indefinite validity.
The collapse of the Soviet Union radically changed the regional situation in the former Soviet space, in particular in the Caspian region. Among a large number of new problems, the problem of the Caspian Sea arose. Instead of two states - the USSR and Iran, which previously bilaterally resolved all emerging issues of maritime navigation, fishing and the use of other living and non-living resources, now there are five of them. Of the former, only Iran remained, Russia took the place of the USSR as successor, the other three are new states: Azerbaijan, Kazakhstan, Turkmenistan. They had access to the Caspian Sea before, but only as republics of the USSR, and not as independent states. Now, having become independent and sovereign, they have the opportunity to participate on equal terms with Russia and Iran in discussions and decision-making in considering all the issues mentioned above. This was also reflected in the attitude of these states towards the Caspian Sea, since all five states that had access to it showed equal interest in using its living and non-living resources. And this is logical, and most importantly, justified: the Caspian Sea is rich in natural resources, both fish stocks and black gold - oil and blue fuel - gas. Exploration and production of the last two resources became the subject of the most heated and protracted negotiations for a long time. But not only them.
In addition to the presence of rich mineral resources, the waters of the Caspian Sea are home to about 120 species and subspecies of fish; here is the global gene pool of sturgeon, the catch of which until recently accounted for 90% of the total world catch.
Due to its location, the Caspian Sea has traditionally and long been widely used for shipping, acting as a kind of transport artery between the peoples of the coastal states. Along its banks there are such large sea ports, like Russian Astrakhan, the capital of Azerbaijan Baku, Turkmen Turkmenbashi, Iranian Anzeli and Kazakh Aktau, between which trade, cargo and passenger maritime transport routes have long been laid.
And yet, the main object of attention of the Caspian states is its mineral resources - oil and natural gas, which each of them can lay claim to within the boundaries that must be determined by them collectively on the basis of international law. And to do this, they will have to divide between themselves both the waters of the Caspian Sea and its bottom, in the depths of which its oil and gas are hidden, and develop rules for their extraction with minimal damage to a very fragile environment, especially the marine environment and its living inhabitants.
The main obstacle in resolving the issue of starting widespread mining of Caspian mineral resources for the Caspian states continues to be its international legal status: should it be considered a sea or a lake? The complexity of the issue lies in the fact that these states themselves must resolve it, and there is no agreement yet among them. But at the same time, each of them strives to quickly begin production of Caspian oil and natural gas and make their sale abroad a constant source of funds to form their budget.
Therefore, oil companies of Azerbaijan, Kazakhstan and Turkmenistan, without waiting for the end of the settlement of existing disagreements over the territorial division of the Caspian Sea, have already begun active production of its oil, in the hope of ceasing to be dependent on Russia, turning their countries into oil-producing countries and, in this capacity, starting to build their own long-term trade relations with neighbors.
However, the issue of the status of the Caspian Sea remains unresolved. Regardless of whether the Caspian states agree to consider it a “sea” or a “lake”, they will have to apply the principles corresponding to the choice made to the territorial division of its water area and bottom or develop their own for this case.
Kazakhstan advocated recognition of the Caspian Sea by the sea. Such recognition will make it possible to apply the provisions of the 1982 UN Convention on the Law of the Sea on Internal Waters, the Territorial Sea, the Exclusive Economic Zone, and the Continental Shelf to the division of the Caspian Sea. This would allow coastal states to gain sovereignty over the subsoil of the territorial sea (Article 2) and exclusive rights to the exploration and development of resources on the continental shelf (Article 77). But the Caspian Sea cannot be called a sea from the standpoint of the 1982 UN Convention on the Law of the Sea, since this body of water is closed and has no natural connection with the world ocean.
In this case, the option of sharing its water area and bottom resources is also excluded.
In the agreements between the USSR and Iran, the Caspian Sea was considered as a border lake. With the Caspian Sea being given the legal status of a “lake”, it is expected to be divided into sectors, as is done in relation to border lakes. But there is no norm in international law obliging states to do exactly this: division into sectors is an established practice.
The Russian Foreign Ministry has repeatedly made statements that the Caspian Sea is a lake, and its waters and subsoil are the common property of the coastal states. Iran also, from a position enshrined in treaties with the USSR, considers the Caspian Sea to be a lake. The country's government believes that this status implies the creation of a consortium for unified management of the production and use of its resources by the Caspian states. Some authors also share this opinion, for example, R. Mamedov believes that with this status, the extraction of hydrocarbon resources in the Caspian Sea by these states should be carried out jointly.
In the literature, a proposal was made to give the Caspian Sea the status of a “sui generis” lake, and in this case we are talking about the special international legal status of such a lake and its special regime. A regime implies the joint development by states of their own rules for the use of its resources.
Thus, recognition of the Caspian Sea as a lake does not require its obligatory division into sectors - each coastal state has its own part. In addition, in international law there are no rules at all on the division of lakes between states: this is their good will, behind which certain internal interests may be hidden.
Currently everything Caspian states recognize that the modern legal regime was established by the established practice of its use, but now the Caspian Sea is in actual common use not of two, but of five states. Even at the meeting of foreign ministers held in Ashgabat on November 12, 1996, the Caspian states confirmed that the status of the Caspian Sea can be changed only with the consent of all five coastal states. This was later also confirmed by Russia and Azerbaijan in a joint statement dated January 9, 2001 on the principles of cooperation, as well as in the Declaration on Cooperation in the Caspian Sea signed between Kazakhstan and Russia dated October 9, 2000.
But during numerous Caspian negotiations, conferences and four summits of the Caspian states (Ashgabat summit on April 23-24, 2002, Tehran summit on October 16, 2007, Baku summit on November 18, 2010 and Astrakhan on September 29, 2014) agreement was reached by the Caspian countries failed to achieve this.
So far, cooperation at the bilateral and trilateral level is proving more productive. Back in May 2003, Russia, Azerbaijan and Kazakhstan entered into an agreement on the junction point of the demarcation lines of adjacent sections of the Caspian Sea bottom, which was based on previous bilateral agreements. In the current situation, Russia, by its participation in these agreements, seemed to confirm that the agreements between the USSR and Iran are outdated and do not correspond to existing realities.
In the Agreement of July 6, 1998 between the Russian Federation and the Republic of Kazakhstan on the delimitation of the bottom of the northern part of the Caspian Sea in order to exercise sovereign rights to subsoil use, it was announced that the seabed would be delimited between adjacent and opposite parties along a modified median line based on the principle of fairness and agreement of the parties. At the bottom of the site, states have sovereign rights, but their common use of the water surface is preserved.
Iran perceived this agreement as separate and in violation of previous Treaties with the USSR in 1921 and 1940. However, it should be noted that in the preamble of the 1998 agreement, to which Russia and Kazakhstan were parties, the agreement was considered as a temporary measure pending the signing of the convention by all Caspian states.
Later, on July 19 of the same year, Iran and Russia made a joint statement in which they proposed three possible scenarios for the delimitation of the Caspian Sea. First: the sea should be shared on the basis of the condominium principle. The second scenario comes down to dividing the water area, waters, bottom and subsoil into national sectors. The third scenario, which is a compromise between the first and second options, involves dividing only the bottom between the coastal states, and considering the water surface to be common and open to all coastal countries.
The existing options for delimiting the Caspian Sea, including those mentioned above, are possible only if there is good political will of the parties. Azerbaijan and Kazakhstan have clearly expressed their position from the very beginning of the multilateral consultation process. Azerbaijan considers the Caspian Sea to be a lake and therefore should be divided. Kazakhstan proposes to consider the Caspian Sea a closed sea, citing the 1982 UN Convention (Articles 122, 123), and, accordingly, advocates its division in the spirit of the Convention. Turkmenistan has long supported the idea of joint management and use of the Caspian Sea, but foreign companies already developing resources off the coast of Turkmenistan influenced the policies of its president, who began to object to the establishment of a condominium regime, supporting the position of dividing the sea.
The first of the Caspian states to begin to use the hydrocarbon riches of the Caspian Sea under new conditions was Azerbaijan. After the conclusion of the “Deal of the Century” in September 1994, Baku expressed a desire to declare the adjacent sector an integral part of its territory. This provision was enshrined in the Constitution of Azerbaijan, adopted in order to exercise sovereign rights to subsoil use, Moscow, July 6, 1998, at a referendum on November 12, 1995 (Article 11). But such a radical position from the very beginning did not correspond to the interests of all other coastal states, especially Russia, which has expressed fears that this would open access to the Caspian Sea to countries in other regions. Azerbaijan agreed to a compromise. The 2002 Agreement between the Russian Federation and Azerbaijan on the delimitation of adjacent areas of the Caspian Sea established a provision in which the division of the bottom was carried out using the median line, and the water area of the reservoir remained in joint use.
Unlike Azerbaijan, which has expressed a desire to completely divide the Caspian Sea, Iran proposes to leave its subsoil and water for joint use, but does not object to the option of dividing the Caspian Sea into 5 equal parts. Accordingly, each member of the Caspian Five would be allocated 20 percent of the total territory of the reservoir.
Russia's point of view was changing. Moscow has long insisted on establishing a condominium, but wanting to build a long-term policy with its neighbors, who were not interested in considering the Caspian Sea as the property of five coastal states, it changed its position. This then prompted the states to begin a new stage of negotiations, at the end of which the above Agreement was signed in 1998, where Russia stated that it was “ripe” for the division of the Caspian Sea. Its main principle was the position “common water - divide the bottom.”
Taking into account the fact that some Caspian states, namely Azerbaijan, Kazakhstan and Russia, have reached agreements on the conditional delimitation of spaces in the Caspian Sea, we can conclude that they are actually satisfied with the already established regime with the division of its bottom along a modified median line and the joint use of the surface reservoir for navigation and fishing.
However, the lack of complete clarity and unity in the position of all coastal countries prevents the Caspian states themselves from developing oil production. And oil is of key importance to them. There is no clear data regarding their reserves in the Caspian Sea. According to the US Energy Information Agency in 2003, the Caspian Sea ranked second in oil reserves and third in gas reserves. The data from the Russian side is different: they speak of an artificial overestimation by Western experts of the energy resources of the Caspian Sea. Differences in assessments are due to the political and economic interests of regional and external players. The geopolitical significance of the region, which is associated with the foreign policy plans of the US and the EU, became a factor in the distortion of the data. Zbigniew Brzezinski expressed the opinion back in 1997 that this region is the “Eurasian Balkans”.
There are still disputes about the status of the Caspian Sea. The fact is that, despite its generally accepted name, it is still the largest endorheic lake in the world. It was called the sea because of the features of the structure of the bottom. It is formed by oceanic crust. In addition, the water in the Caspian Sea is salty. As at sea, there are often storms and strong winds that raise high waves.
Geography
The Caspian Sea is located at the junction of Asia and Europe. In its shape, it resembles one of the letters of the Latin alphabet - S. From south to north, the sea stretches for 1200 km, and from east to west - from 195 to 435 km.
The territory of the Caspian Sea is heterogeneous in its physical and geographical conditions. In this regard, it is conditionally divided into 3 parts. These include the Northern and Middle, as well as the Southern Caspian.
Coastal countries
Which countries is washed by the Caspian Sea? There are only five of them:
- Russia, located in the northwest and west. The length of the coastline of this state along the Caspian Sea is 695 km. Kalmykia, Dagestan and the Astrakhan region, which are part of Russia, are located here.
- Kazakhstan. It is a country on the shores of the Caspian Sea, located in the east and northeast. The length of its coastline is 2320 km.
- Turkmenistan. The map of the Caspian states indicates that this country is located in the southeast of the water basin. The length of the line along the coast is 1200 km.
- Azerbaijan. This state, stretching 955 km along the Caspian Sea, washes its shores in the southwest.
- Iran. A map of the Caspian states indicates that this country is located at southern shores endorheic lake. Moreover, the length of its sea borders is 724 km.
Is the Caspian Sea?
The dispute over what to call this unique body of water has not yet been resolved. And it is important to answer this question. The fact is that all countries on the Caspian Sea have their own interests in this region. However, the governments of five states have not been able to resolve the question of how to divide this huge body of water for a long time. The most important controversy revolved around the name. Is the Caspian Sea a sea or a lake? Moreover, the answer to this question is of no more interest to geographers. First of all, politicians need it. This is due to the application of international law.
Caspian states such as Kazakhstan and Russia believe that their borders in this region are washed by the sea. In this regard, representatives of the two indicated countries insist on the application of the UN Convention adopted in 1982. It concerns the law of the sea. The provisions of this document state that coastal states are allocated a twelve-mile water zone along it. In addition, the country is granted the right to economic maritime territory. It is located two hundred miles away. The coastal state also has rights to However, even the widest part of the Caspian Sea is narrower than the distance specified in the international document. In this case, the middle line principle can be applied. At the same time, the Caspian states, which have the greatest length of coastal borders, will receive a large maritime territory.
Iran has a different opinion on this matter. Its representatives believe that the Caspian Sea should be divided fairly. In this case, all countries will get twenty percent of the maritime territory. The position of official Tehran can be understood. With this solution to the issue, the state will manage a larger zone than when dividing the sea along the middle line.
However, the Caspian Sea changes its water level significantly from year to year. This does not allow us to determine its median line and divide the territory between states. Countries such as Azerbaijan, Kazakhstan and Russia have signed an agreement among themselves defining the bottom zones in which the parties will exercise their economic rights. Thus, a certain legal truce has been achieved in the northern territories of the sea. The southern countries of the Caspian Sea have not yet come to a common decision. However, they do not recognize the agreements reached by their northern neighbors.
Is the Caspian a lake?
Adherents of this point of view proceed from the fact that the reservoir, located at the junction of Asia and Europe, is closed. In this case, it is impossible to apply a document on the norms of international maritime law to it. Proponents of this theory are convinced that they are right, citing the fact that the Caspian Sea does not have a natural connection with the waters of the World Ocean. But here another difficulty arises. If the lake is the Caspian Sea, the boundaries of states according to what international standards should be determined in its water spaces? Unfortunately, such documents have not yet been developed. The fact is that the issues of the international lake have not been discussed anywhere by anyone.
Is the Caspian Sea a unique body of water?
In addition to those listed above, there is another, third point of view on the ownership of this amazing body of water. Its supporters are of the opinion that the Caspian Sea should be recognized as an international water basin, belonging equally to all countries bordering it. In their opinion, the resources of the region are subject to joint exploitation by countries bordering the reservoir.
Solving security problems
The Caspian states are doing everything possible to eliminate all existing disagreements. And in this matter, positive developments can be noted. One of the steps towards solving problems related to the Caspian region was the agreement signed on November 18, 2010 between all five countries. It concerns issues of security cooperation. In this document, the countries agreed on joint activities to eliminate terrorism, drug trafficking, smuggling, poaching, money laundering, etc. in the region.
Environmental protection
Particular attention is paid to solving environmental issues. The territory in which the Caspian states and Eurasia are located is a region under the threat of industrial pollution. Kazakhstan, Turkmenistan and Azerbaijan dump waste from energy exploration and production into the Caspian waters. Moreover, it is in these countries that large number abandoned oil wells that are not exploited due to their unprofitability, but nevertheless continue to have an adverse impact on the environmental situation. As for Iran, it dumps agricultural waste and sewage into sea waters. Russia threatens the ecology of the region with industrial pollution. This is due to the economic activity that took place in the Volga region.
Countries on the Caspian Sea have made some progress in addressing environmental problems. Thus, since August 12, 2007, the Frame Convection has been in force in the region, with the goal of protecting the Caspian Sea. This document develops provisions on the protection of biological resources and regulation of anthropogenic factors affecting the aquatic environment. According to this convection, the parties must interact when carrying out measures to improve the environmental situation in the Caspian Sea.
In 2011 and 2012, all five countries signed other documents significant for the protection of the marine environment. Among them:
- Protocol on cooperation, response and regional preparedness in the event of oil pollution incidents.
- Protocol concerning the protection of the region against pollution from land-based sources.
Development of gas pipeline construction
Today, another problem remains unresolved in the Caspian region. It concerns the laying of this idea. This idea is an important strategic task of the West and the United States, which continue to look for alternative energy sources to Russian ones. That is why, when resolving this issue, the parties do not turn to countries such as Kazakhstan, Iran and, of course, the Russian Federation. Brussels and Washington supported the statement made in Baku on November 18, 2010 at the summit of the heads of the Caspian countries. He expressed the official position of Ashgabat regarding the laying of the pipeline. Turkmen authorities believe that the project should be implemented. At the same time, only those states on whose bottom territories it will be located must give their consent to the construction of the pipeline. And this is Turkmenistan and Azerbaijan. Iran and Russia opposed this position and the project itself. At the same time, they were guided by the issues of protecting the Caspian ecosystem. To date, the construction of the pipeline is not underway due to disagreement between the project participants.
Holding the first summit
Countries on the Caspian Sea are constantly looking for ways to solve the problems that have arisen in this Eurasian region. For this purpose, special meetings of their representatives are organized. Thus, the first summit of the heads of the Caspian states took place in April 2002. Its venue was Ashgabat. However, the results of this meeting did not live up to expectations. The summit was considered unsuccessful due to Iran's demands to divide the sea area into 5 equal parts. Other countries categorically opposed this. Their representatives defended their own point of view that the size of national waters should correspond to the length of the state’s coastline.
The failure of the summit was also provoked by a dispute between Ashgabat and Baku over the ownership of three oil fields located in the center of the Caspian Sea. As a result, the heads of five states did not develop a consensus on any of all the issues raised. However, an agreement was reached to hold a second summit. It was supposed to take place in 2003 in Baku.
Second Caspian Summit
Despite the existing agreements, the planned meeting was postponed every year. The heads of the Caspian states gathered for the second summit only on October 16, 2007. It was held in Tehran. At the meeting, current issues related to determining the legal status of the unique body of water that is the Caspian Sea were discussed. The borders of states within the division of the water area were previously agreed upon during the development of the draft of the new convention. Problems of security, ecology, economics and cooperation of coastal countries were also raised. In addition, the results of the work that the states carried out after the first summit were summed up. In Tehran, representatives of the five states also outlined ways for further cooperation in the region.
Meeting at the third summit
Once again, the heads of the Caspian countries met in Baku on November 18, 2010. The result of this summit was the signing of an agreement to expand cooperation regarding security issues. During the meeting, it was pointed out that which countries are washed by the Caspian Sea, only those should ensure the fight against terrorism, transnational crime, weapons proliferation, etc.
Fourth summit
Once again, the Caspian states raised their problems in Astrakhan on September 29, 2014. At this meeting, the presidents of the five countries signed another statement.
In it, the parties recorded the exclusive right of the coastal countries to station armed forces in the Caspian Sea. But even at this meeting the status of the Caspian Sea was not finally regulated.
I was resting somehow in the camp. It's no secret that almost every day competitions are held there to entertain children and youth. So here it is. Was with us quiz. Question: “Which lake is the largest?” One guy of about fifteen was the first to raise his hand and answer: “Baikal.” The strangest thing was that his answer was counted as correct! How so? Isn't the Caspian Sea the largest lake? Now I will explain to you.
How to distinguish a sea from a lake
I'll list several signs by which a body of water is defined as a sea.
1. Rivers can flow into the sea.
2. The outer sea has direct access to the ocean.
3. If the sea is internal, then it is connected by straits with other seas or directly with the ocean.
Does the Caspian Sea fit sea parameters?
Need to check does the Caspian Sea have signs of a sea. into it really rivers flow in, but they flow into many bodies of water: seas, lakes, oceans, and other rivers. The Caspian Sea is surrounded from all sides by land. Is this really inland sea? Then it must connect with Black or Seas of Azov somehow strait. Strait Same No. Exactly due to the lack of access to the World Ocean, the Caspian Sea is considered a lake.
“But why was it called the sea then, if it is a lake?”- you ask. Answer very simple: because of his large sizes and salinity. In fact, The Caspian Sea is several times larger than the Azov Sea and almost equal in size to the Baltic Sea.
Great! The problem with the quiz has been resolved. Judge to hell!!!
Well then, I told, that the Caspian Sea In fact - lake. Now I want to you provide small a selection of interesting facts about this lake.
1. The Caspian Sea is below sea level (-28 m), which once again proves that this is a lake.
2. BC near the lake area lived nomadic Caspian tribes,in honor of which he was nicknamed Caspian.
3. This the deepest enclosed body of water on the planet.
4. Many people think that the name of the group “Caspian Cargo” is related to the Caspian Sea. In some ways they are right ( No). In fact the expression “Caspian cargo” can mean any illegal cargo.
5.Caspian Sea Fine suitable for tourism. During the USSR, a large number of sanatoriums were built here. Today or here you can see many hotels, water parks and beaches.
