Updates? Oil wells were being dug in the region as early as the 10th century to reach oil "for use in everyday life, both for medicinal purposes and for heating and lighting in homes". The Caspian Sea Shipping Company CJSC has two fleets plus shipyards. The Caspian basin, as a whole, is usually divided into the northern, middle, and southern Caspian, based partly on underwater relief and partly on hydrologic characteristics. The proposed Pechora–Kama Canal was a project that was widely discussed between the 1930s and 1980s. Thus boron content in product water exceeds hygienic standards. Overfishing has depleted a number of the historic fisheries. In the North Caspian, the majority of the islands are small and uninhabited, like the Tyuleniy Archipelago, an Important Bird Area (IBA), although some of them have human settlements. A series of submerged ridges breaks up the relief to the north, but otherwise the bottom of the depression is a flat plain and contains the Caspian’s greatest depths. Whether it was in law a sea, lake or an agreed hybrid, set the demarcation rules and was heavily debated. The Caspian Sea is salty because it receives flow from many rivers that bring dissolved salts downstream. [27] Caviar harvesting further endangers the fish stocks, since it targets reproductive females. Scheduled ferry services (including train ferries) across the sea chiefly are between: As an endorheic basin, the Caspian Sea basin has no natural connection with the ocean. Unlike many other lakes, the Caspian has no outflowing rivers, and major rivers such as the Volga, Ural, Kura and Terek feed into the sea. (Comparable evaporite beds underlie the Mediterranean.) [64], The Caspian Summit is a head of state-level meeting of the five littoral states. A second affluent, the Ural River, flows in from the north, and the Kura River flows into the sea from the west. Lacking an outlet, the Caspian Sea loses water only by evaporation, leading to the accumulation of salt. The current disputes along Azerbaijan's maritime borders with Turkmenistan and Iran could impinge future development. By 1900, Baku had more than 3,000 oil wells, 2,000 of which were producing at industrial levels. For the most part, the eastern shore of the middle Caspian is precipitous, with the sea destroying the margin of the limestone plateaus of Tüpqaraghan and Kendyrli-Kayasansk. Russia, Kazakhstan, and Azerbaijan have bilateral agreements with each other based on median lines. [67], The five littoral states build consensus on legally binding governance of the Caspian Sea through Special Working Groups of a Convention on the Legal Status of the Caspian Sea. Roughly 130 rivers feed the giant lake, and nearly all of them enter from the north or west. Depth reaches near the centre 788 metres, and in the southern part, 1,025 metres. The Vladimir Filanovsky oil field in the Russian section of the body of water was discovered in 2005. Blue-green algae (cyanobacteria) and diatoms constitute the greatest biomass concentrations, and there are several species of red and brown algae. Calculations of the speed of sound (u) and compressibility (/3) of Caspian Sea water from the composition data indicate differences of 4.8 m s- 1 in u and 2.10 10-6 bar 1 in/3 between Caspian Sea and seawaters. This has been attributed to a general lack of seeding material in newly formed coastal lagoons and water bodies. [46], The Caspian countries develop robust cooperation in the tech and digital field as part of the Caspian Digital Hub. [45], Caspian littoral states join efforts to develop infrastructure, tourism and trade in the region. The maximum depth, toward the south, is 3,360 feet (1,025 metres) below the sea’s surface. The salt content increases over time as more of it is brought down with the rivers and streams that empty into the Caspian Sea. [7] Currently, the mean salinity of the Caspian is one third that of Earth's oceans. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. The UN Environment Programme warns that the Caspian "suffers from an enormous burden of pollution from oil extraction and refining, offshore oil fields, radioactive wastes from nuclear power plants and huge volumes of untreated sewage and industrial waste introduced mainly by the Volga River". The most likely route for the canal, the officials at the Committee on Water Resources at Kazakhstan's Agriculture Ministry say, would follow the Kuma–Manych Depression, where currently a chain of rivers and lakes is already connected by an irrigation canal (the Kuma–Manych Canal). [9] The Volga River (about 80% of the inflow) and the Ural River discharge into the Caspian Sea, but it has no natural outflow other than by evaporation. It is called a sea and not a lake because when the Ancient Romans arrived there, they discovered that the water was salty (about a third as salty as regular seawater); they named the sea after the Caspian tribe that lived there. However, the comparison of of the Caspian water to oceanic water shows that it contains three times less salt than that of the World Ocean. [2] Strabo (died about 24 AD) wrote that "to the country of the Albanians (Caucasus Albania not to be confused with the country of Albania) belongs also the territory called Caspiane, which was named after the Caspian tribe, as was also the sea; but the tribe has now disappeared". The sea stretches nearly 1,200 kilometres (750 mi) from north to south, with an average width of 320 km (200 mi). [53] However, analysts note that the pipelines would bypass Russia completely, thereby denying the country valuable transit fees, as well as destroying its current monopoly on westward-bound hydrocarbon exports from the region. This underpinning a modest birth rate and wide higher education sector leads them capitalise from their high-value natural-resource-based economies. Its lower reaches are heavily developed with numerous unregulated releases of chemical and biological pollutants. Although a lake, the Caspian is not a freshwater lake; the water delivered by the Volga River minimizes the lake’s salt content at the northern end, but the Caspian grows more saline to the south. The Caspian Sea is the world's largest inland sea. If the Caspian Sea is a lake, it contains 40 percent of all lake water in the world. These were published in 1720 by the Russian Academy of Sciences.[40].

The Caspian Sea is an important regional water reservoir, as well as a biological and commercial center, despite its salt content. During warm and dry climatic periods, the landlocked sea almost dried up, depositing evaporitic sediments like halite that were covered by wind-blown deposits and were sealed off as an evaporite sink when cool, wet climates refilled the basin. Over the centuries, Caspian Sea levels have changed in synchrony with the estimated discharge of the Volga, which in turn depends on rainfall levels in its vast catchment basin. The Caspian littoral states' meeting in 2007 signed an accord that only allows litoral-state flag-bearing ships to enter the sea. If water is, in law, a sea, many precedents and international treaties oblige free access to foreign vessels. The Caspian is divided into three distinct physical regions: the Northern, Middle, and Southern Caspian. Hoxhaj in 2005 could prove salt water (Fresh water is 0.3 parts per thousand of salts or less; on average, ocean water is about 35 parts per thousand; average for the Caspian Sea is about 13.) In 1980, a dam was built at the mouth of the Kara-Bogaz-Gol to control wa… Iran has an estimated 988.4 trillion cubic feet of natural gas, around 16 percent of world reserves, thus key to current paradigms in global energy security. Fresh water goes into the Caspian Sea through Ural and the Volga Rivers in the north, but the Sea continues to be somewhat salty, south and central. While the Caspian Sea is not fresh water, its salty water is diluted by the inflow of fresh water, especially in the north. Its seafloor is, therefore, a standard oceanic basalt and not a continental granite body. Please select which sections you would like to print: Corrections? "Although Iran is located in an arid and semi-arid area, having access to vast resources of salt water in the north (Caspian Sea) and south (Sea of Oman and the Persian Gulf) offers good prospects. All water entering the sea accumulates or evaporates. The Caspian Sea is the world's largest salt lake. [9] The coastlines of the Caspian are shared by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. [65] The five leaders signed the ‘Convention on the Legal Status of the Caspian Sea’. The shores of the northern Caspian are low and reflect the great accumulation of alluvial material washed down by the Ural, Terek, and, above all, Volga rivers, whose deltas are extensive. The shallowest portion—a shelf with depths reaching 330 to 460 feet (100 to 140 metres)—extends along both shores, with the western slope furrowed by submerged landslides and canyons. [37] By the 16th century, Europeans were aware of the rich oil and gas deposits locally. Conversely, the climate to the southwest and south are generally warm with uneven elevation due to a mix of highlands and mountain ranges; the drastic changes in climate alongside the Caspian have led to a great deal of biodiversity in the region.[8]. This bay was closed between 1980 and 1992. He drew a set of four maps and wrote Pilot of the Caspian Sea, the first lengthy report and modern maps. But, the northern part of the lake can be frozen during winter. It is bordered on the northeast by Kazakhstan, on the southeast by Turkmenistan, on the south by Iran, on the southwest by Azerbaijan, and on the northwest by Russia. [43] Russia's extensive mineral and energy resources are the largest such reserves in the world,[44] making it the second leading producer of oil and natural gas globally. [16], The magnitude of fossil fuel extraction and transport activity in the Caspian also poses a risk to the environment. [16], The Volga River, the largest in Europe, drains 20% of the European land area and is the source of 80% of the Caspian's inflow. [35][36], The area is rich in fossil fuel. Stretching 1,200 kilometers (750 miles) from north to south, it intersects five countries in Asia and Europe. [47], The Caspian Sea region presently is a significant, but not major, supplier of crude oil to world markets, based upon estimates by BP Amoco and the U.S. Energy Information Administration, U.S. Department of Energy. By the end of the 19th century, Baku became known as the "black gold capital", and many skilled workers and specialists flocked to the city.
