Geography and hydrography

File:DEM Baikal lake.png|thumb|left|A digital elevation modeldigital elevation modelFile:Yeniseirivermap.png|thumb|left|The Yenisei RiverYenisei RiverLake Baikal is in a rift valley, created by the Baikal Rift Zone, where the Earth's crust is slowly pulling apart.WEB,weblink The Oddities of Lake Baikal, Alaska Science Forum, 7 January 2007, At {{convert|636|km|abbr=on}} long and {{convert|79|km|abbr=on}} wide, Lake Baikal has the largest surface area of any freshwater lake in Asia, at {{convert|31722|km2|abbr=on}}, and is the deepest lake in the world at {{convert|1642|m|abbr=on}}. The bottom of the lake is {{convert|1186.5|m|abbr=on}} below sea level, but below this lies some {{convert|7|km|abbr=on}} of sediment, placing the rift floor some {{convert|8|-|11|km|abbr=on}} below the surface, the deepest continental rift on Earth. In geological terms, the rift is young and active – it widens about 2 cm (0.8 in) per year. The fault zone is also seismically active; hot springs occur in the area and notable earthquakes happen every few years. The lake is divided into three basins: North, Central, and South, with depths about {{convert|900|m|abbr=on}}, {{convert|1600|m|abbr=on}}, and {{convert|1400|m|abbr=on}}, respectively. Fault-controlled accommodation zones rising to depths about {{convert|300|m|abbr=on}} separate the basins. The North and Central basins are separated by Academician Ridge, while the area around the Selenga Delta and the Buguldeika Saddle separates the Central and South basins. The lake drains into the Angara tributary of the Yenisei. Notable landforms include Cape Ryty on Baikal's northwest coast.Baikal's age is estimated at 25–30 million years, making it the most ancient lake in geological history. It is unique among large, high-latitude lakes, as its sediments have not been scoured by overriding continental ice sheets. Russian, U.S., and Japanese cooperative studies of deep-drilling core sediments in the 1990s provide a detailed record of climatic variation over the past 6.7 million years.Kravchinsky, V.A., M.A. Krainov, M.E.

As the autumn begins, the surface temperature falls again and a second homothermic period at around {{convert|4|C|F|abbr=on}} of the upper circa {{convert|300|m|ft|abbr=on}} occurs in October–November. In the deepest parts of the lake, from about {{convert|300|m|ft|abbr=on}}, the temperature is very stable at {{convert|3.1-3.4|C|F|abbr=on}} with only minor annual variations.The average surface temperature has risen by almost 1.5 Â°C (2.7 Â°F) in the last 50 years, resulting in a shorter period where the lake is covered by ice. At some locations, hydrothermal vents with water that is about {{convert|50|C|F|abbr=on}} have been found.

Flora

The watershed of Lake Baikal has numerous floral species represented. The marsh thistle (Cirsium palustre) is found here at the eastern limit of its geographic range.C. Michael Hogan. 2009.

Granina, Lake Baikal, Shahgedanova, M., 2002, The Physical Geography of Northern Eurasia, Oxford University Press, 403–421, 978-0-19-823384-8, More than 85 species of submerged macrophytes have been recorded, including genera such as Ceratophyllum, Myriophyllum, Potamogeton, and Sparganium. The invasive species Elodea canadensis was introduced to the lake in the 1950s. Instead of vascular plants, aquatic flora is often dominated by several green algae species, notably Draparnaldioides, Tetraspora, and Ulothrix in water shallower than {{convert|20|m|ft|abbr=on|round=5}}; although Aegagrophila, Cladophora, and Draparnaldioides may occur deeper than {{convert|30|m|ft|abbr=on|round=5}}. Except for Ulothrix, there are endemic Baikal species in all these green algae genera. More than 400 diatom species, both benthic and planktonic, are found in the lake, and about half of these are endemic to Baikal; however, significant taxonomic uncertainties remain for this group.

Mammals

The Baikal seal or nerpa (Pusa sibirica) is found throughout Lake Baikal.Peter Saundry. 2010. Baikal seal. Encyclopedia of Earth. Topic ed. C. Michael Hogan, Ed. in chief C. NCSE, Washington D.C. It is one of only three entirely freshwater seal populations in the world, the other two being subspecies of ringed seals.A wide range of land mammals can be found in the habitats around the lake, such as Eurasian brown bear, Eurasian wolf, red fox, sable, stoat, elk, Siberian red deer, reindeer, Siberian roe deer, Siberian musk deer, wild boar, red squirrel, Siberian chipmunk, marmot, lemming, and Alpine hare.WEB, Wildlife of Lake Baikal,weblink bww.irk.ru, 9 June 2017, Until the Early Middle Ages, the wisent (European bison) was present near the lake, which was the easternmost part of its range.Sipko P.T.. 2009.

Amphipod and ostracod crustaceans

File:Baikal-Flohkrebs.jpg|thumb|A "giant" Brachyuropus reicherti (Acanthogammaridae) amphipod caught during ice fishingice fishingMore than 350 species and subspecies of amphipods are endemic to the lake. They are exceptionally diverse in ecology and appearance, ranging from the pelagic Macrohectopus to the relatively large deep-water Abyssogammarus and Garjajewia, the tiny herbivorous Micruropus, and the parasitic Pachyschesis (parasitic on other amphipods).Sherbakov; Kamaltynov; Ogarkov; and Verheyen (1998). Patterns of Evolutionary Change in Baikalian Gammarids Inferred from DNA Sequences (Crustacea, Amphipoda). Molecular Phylogenetics and Evolution 10(2): 160–167 The "gigantism" of some Baikal amphipods, which has been compared to that seen in Antarctic amphipods, has been linked to the high level of dissolved oxygen in the lake.BBC News (13 May 1999). Oxygen boosts polar giants. Retrieved 17 July 2014. Among the "giants" are several species of spiny Acanthogammarus and Brachyuropus (Acanthogammaridae) found at both shallow and deep depths.Daneliya, M.E.; Kamaltynov, R.M.; and Väinölä, R. (2011).

History

The Baikal area, sometimes known as Baikalia, has a long history of human habitation. An early known tribe in the area was the Kurykans.BOOK, Lincoln, W.B., The Conquest of a Continent: Siberia and the Russians, 246, 2007, Cornell University Press, 978-0-8014-8922-8, Located in the former northern territory of the Xiongnu confederation, Lake Baikal is one site of the Han–Xiongnu War, where the armies of the Han dynasty pursued and defeated the Xiongnu forces from the second century BC to the first century AD. They recorded that the lake was a "huge sea" (hanhai) and designated it the North Sea (Běihǎi) of the semimythical Four Seas.BOOK, Chun-shu, Chang, The Rise of the Chinese Empire: Nation, State, and Imperialism in Early China, ca. 1600 B.C.-A.D. 8, 2007, University of Michigan Press, 978-0-472-11533-4, 264, The Kurykans, a Siberian tribe who inhabited the area in the sixth century, gave it a name that translates to "much water". Later on, it was called "natural lake" (Baygal nuur) by the Buryats and "rich lake" (Bay göl) by the Yakuts.BOOK, W. Bruce, Lincoln, The Conquest of a Continent: Siberia and the Russians, 2007, Cornell University Press, 978-0-8014-8922-8, 246, Little was known to Europeans about the lake until Russia expanded into the area in the 17th century. The first Russian explorer to reach Lake Baikal was Kurbat Ivanov in 1643.WEB,weblink Research of the Baikal, Irkutsk.org, 18 January 2006, 2012-01-02, Russian expansion into the Buryat area around Lake BaikalGeorge V. Lantzeff and Richard A. Price, 'Eastward to Empire',1973 in 1628–58 was part of the Russian conquest of Siberia. It was done first by following the Angara River upstream from Yeniseysk (founded 1619) and later by moving south from the Lena River. Russians first heard of the Buryats in 1609 at Tomsk. According to folktales related a century after the fact, in 1623, Demid Pyanda, who may have been the first Russian to reach the Lena, crossed from the upper Lena to the Angara and arrived at Yeniseysk.WEB,weblink ru:Открытие Русскими Средней И Восточной Сибири, Randewy.ru, 2012-01-02, Russian, Vikhor Savin (1624) and Maksim Perfilyev (1626 and 1627–28) explored Tungus country on the lower Angara. To the west, Krasnoyarsk on the upper Yenisei was founded in 1627. A number of ill-documented expeditions explored eastward from Krasnoyarsk. In 1628, Pyotr Beketov first encountered a group of Buryats and collected yasak (tribute) from them at the future site of Bratsk. In 1629, Yakov Khripunov set off from Tomsk to find a rumored silver mine. His men soon began plundering both Russians and natives. They were joined by another band of rioters from Krasnoyarsk, but left the Buryat country when they ran short of food. This made it difficult for other Russians to enter the area. In 1631, Maksim Perfilyev built an ostrog at Bratsk. The pacification was moderately successful, but in 1634, Bratsk was destroyed and its garrison killed. In 1635, Bratsk was restored by a punitive expedition under Radukovskii. In 1638, it was besieged unsuccessfully.{{citation needed|date=August 2015}}In 1638, Perfilyev crossed from the Angara over the Ilim portage to the Lena River and went downstream as far as Olyokminsk. Returning, he sailed up the Vitim River into the area east of Lake Baikal (1640) where he heard reports of the Amur country. In 1641, Verkholensk was founded on the upper Lena. In 1643, Kurbat Ivanov went further up the Lena and became the first Russian to see Lake Baikal and Olkhon Island. Half his party under Skorokhodov remained on the lake, reached the Upper Angara at its northern tip, and wintered on the Barguzin River on the northeast side.{{citation needed|date=August 2015}}In 1644, Ivan Pokhabov went up the Angara to Baikal, becoming perhaps the first Russian to use this route, which is difficult because of the rapids. He crossed the lake and explored the lower Selenge River. About 1647, he repeated the trip, obtained guides, and visited a 'Tsetsen Khan' near Ulan Bator. In 1648, Ivan Galkin built an ostrog on the Barguzin River which became a center for eastward expansion. In 1652, Vasily Kolesnikov reported from Barguzin that one could reach the Amur country by following the Selenga, Uda, and Khilok Rivers to the future sites of Chita and Nerchinsk. In 1653, Pyotr Beketov took Kolesnikov's route to Lake Irgen west of Chita, and that winter his man Urasov founded Nerchinsk. Next spring, he tried to occupy Nerchensk, but was forced by his men to join Stephanov on the Amur. Nerchinsk was destroyed by the local Tungus, but restored in 1658.{{citation needed|date=August 2015}}The Trans-Siberian Railway was built between 1896 and 1902. Construction of the scenic railway around the southwestern end of Lake Baikal required 200 bridges and 33 tunnels. Until its completion, a train ferry transported railcars across the lake from Port Baikal to Mysovaya for a number of years. The lake became the site of the minor engagement between the Czechoslovak legion and the Red Army in 1918. At times during winter freezes, the lake could be crossed on foot, though at risk of frostbite and deadly hypothermia from the cold wind moving unobstructed across flat expanses of ice. In the winter of 1920, the Great Siberian Ice March occurred, when the retreating White Russian Army crossed frozen Lake Baikal. The wind on the exposed lake was so cold, many people died, freezing in place until spring thaw.

Ecotourism

(File:Лёд_Байкала.jpg|thumb|Crevasses of Baikal ice)Baikal has a number of different tourist activities, depending on season. Generally Baikal has two top tourist seasons. The first season is ice season, which starts usually in mid-January and lasts till mid-April.WEB,weblink Lake Baikal Travel Guide - Top Ten Attractions on Lake Baikal, 23 November 2017, During this season ice depth increases up to 140 centimeters, that allows quite safe vehicle driving on the ice cover (except heavy vehicles, such as tourist buses, that do not take this risk). This allows access to the figures of ice that are formed at rocky banks of Olkhon Island, including Cape Hoboy, the Three Brothers rock, and caves to the North of Khuzhir. It also provides access to small islands like Ogoy Island and Zamogoy.The ice itself has a transparency of one meter depth, having different patterns of crevasses, bubbles, and sounds.{{citation needed|date=March 2019}} That is why this season is popular for hiking, ice-walking, ice-skating, and bicycle-riding.{{citation needed|date=March 2019}} An ice route around Olkhon is around 200 km. Some tourists may spot a Baikal seal along the route. Local entrepreneurs offer overnight in Yurt on ice. Also this season attracts fans of ice fishing. This activity is most popular on Buryatia side of Baikal (Ust-Barguzin). Non-fishermen may try fresh Baikal fresh fish on local markets in villages (Listvyanka, Ust-Barguzin).The ice season ends in mid-April. Owing to increasing temperatures ice starts to melt and becomes shallow and fragile, especially in places with strong under-ice flows. Vehicles and people start to fall under ice. This leads to many casualties every year.{{citation needed|date=March 2019}}Second tourist season is summer, which lets tourists dive deeper into virgin Baikal nature. Hiking trails become openweblink many of them cross two mountain ranges: Baikal Range on the western side and Barguzin Range on the eastern side of Baikal. The most popular trail starts in Listvyanka and goes along the Baikal coast to Bolshoye Goloustnoye. The total length of the route is 55 km, but the most part of tourists usually take only a part of it — a section of 25 km to Bolshie Koty.

Baykalsk Pulp and Paper Mill

(File:Bajkal'sk paper.jpg|thumb|left|Baykalsk Pulp and Paper Mill in 2008, 5 years before its closure)The Baykalsk Pulp and Paper Mill was constructed in 1966, directly on the shoreline of Lake Baikal. The plant bleached paper using chlorine and discharged waste directly into Lake Baikal. The decision to construct the plant on the Lake Baikal resulted in strong protests from Soviet scientists; according to them, the ultra-pure water of the lake was a significant resource and should have been used for innovative chemical production (for instance, the production of high-quality viscose for the aeronautics and space industries). The Soviet scientists felt that it was irrational to change Lake Baikal's water quality by beginning paper production on the shore. It was their position that it was also necessary to preserve endemic species of local biota, and to maintain the area around Lake Baikal as a recreation zone.Sobisevich A. V., Snytko V. A.

Protests against Chinese investments at Lake Baikal

Chinese investments to develop the new Silk Road have triggered protests in Russia. After Chinese investors presented plans to pump water from Lake Baikal and send it to China, an anti-Chinese-investor attitude has emerged in Siberia. Many people in Siberia complain that the Chinese build hotels, but the jobs go to Chinese people rather than Russians. Russian guest house and hotel operators complain that Chinese investors do not involve them and take tourism business away from the local people. Especially great concerns arise because of environmental damage. The local authorities have already stopped numerous projects by Chinese investors in response to the protests.WEB,weblink Fuelled by China fears, Russians protest Baikal bottling plant, phys.org, en-us, 2019-05-06, WEB,weblink Russland: Angst vor China – Weltspiegel – ARD {{!, Das Erste|website=www.daserste.de|language=de|access-date=2019-05-06}}
