[[File:LakeVostok-Location.jpg|thumb|270px|Location of Vostok in Antarctica]]&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Vostok Station&amp;#039;&amp;#039;&amp;#039; ({{langx|ru|станция Восток|stantsiya Vostok}}, {{IPA|ru|ˈstant͡sɨjə vɐˈstok|IPA}}, {{lit|station east}}) is a Russian [[Research stations in Antarctica|research station]] in inland [[Princess Elizabeth Land]], [[Antarctica]]. Founded by the [[Soviet Union]] in 1957, the station lies at the southern [[Pole of Cold]], with the [[List of weather records#Lowest temperatures recorded|lowest reliably measured natural temperature on Earth]] of {{cvt|−89.2|C|F K}}.&amp;lt;ref name=&amp;quot;NCDC&amp;quot;&amp;gt;[http://www.ncdc.noaa.gov/oa/climate/globalextremes.html Global Measured Extremes of Temperature and Precipitation.] [[National Climatic Data Center]]. Retrieved on 21 June 2007.&amp;lt;/ref&amp;gt; Research includes [[ice core]] drilling and [[Magnetometer|magnetometry]]. Vostok was named after &amp;#039;&amp;#039;[[Vostok (sloop-of-war)|Vostok]]&amp;#039;&amp;#039;, the lead ship of the First Russian Antarctic Expedition captained by [[Fabian Gottlieb von Bellingshausen|Fabian von Bellingshausen]]. The [[Bellingshausen Station]] was named after this captain (the second ship, &amp;#039;&amp;#039;[[Mirny (sloop-of-war)|Mirny]]&amp;#039;&amp;#039;, captained by [[Mikhail Lazarev]], became the namesake for [[Mirny Station]]).&lt;br /&gt;
&lt;br /&gt;
==Description==&lt;br /&gt;
Vostok Research Station is around {{convert|1301|km}} from the [[Geographic South Pole]], at the middle of the East [[Antarctic Ice Sheet]].&lt;br /&gt;
&lt;br /&gt;
Vostok is located near the southern [[pole of inaccessibility]] and the [[south geomagnetic pole]], making it one of the optimal places to observe changes in the Earth&amp;#039;s [[magnetosphere]]. Other studies include [[Actinometer|actinometry]], [[geophysics]], medicine and [[climatology]].&lt;br /&gt;
&lt;br /&gt;
The station is at {{convert|3488|m}} above [[sea level]] and is one of the most isolated established research stations on the Antarctic continent.&amp;lt;ref name=&amp;quot;Winchester 2003 168–169&amp;quot;&amp;gt;{{cite book|last=Winchester|first=Simon|authorlink=Simon Winchester|title=Extreme Earth|publisher=Collins|year=2003|pages=168–169|isbn=0-00-716392-4}}&amp;lt;/ref&amp;gt; The station was supplied from [[Mirny Station]] on the Antarctic coast.&amp;lt;ref&amp;gt;{{cite web|url=http://www.aari.nw.ru/projects/Antarctic/stations/mir/mir_en.html|archive-url=https://web.archive.org/web/20151219011635/http://www.aari.nw.ru/projects/Antarctic/stations/mir/mir_en.html|url-status=dead|archive-date=19 December 2015|title=Mirny Observatory|date=14 July 2018}}&amp;lt;/ref&amp;gt; The station normally hosts 30 scientists and engineers in the summer. In winter, their number drops to 15.&amp;lt;ref name=&amp;quot;comnap-catalogue&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The only permanent research station located farther south is the [[Amundsen–Scott South Pole Station]], operated by the United States at the geographic [[South Pole]]. The Chinese [[Kunlun Station]] is farther south than Vostok but is occupied only during summers.&lt;br /&gt;
&lt;br /&gt;
Some of the challenges faced by those living on the station were described in [[Vladimir Sanin]]&amp;#039;s books such as &amp;#039;&amp;#039;Newbie in the Antarctic&amp;#039;&amp;#039; (1973), &amp;#039;&amp;#039;72 Degrees Below Zero&amp;#039;&amp;#039; (1975), and others.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
[[File:GISP2 team photo core37.jpeg|thumb|left|Ice cores at Vostok, with a portion of the station behind]]&lt;br /&gt;
Vostok Station was established on 16 December 1957 (during the [[International Geophysical Year]]) by the [[2nd Soviet Antarctic Expedition]] and was operated year-round for more than 72 years.&amp;lt;ref name=igsoc&amp;gt;{{cite web|url=http://www.igsoc.org/annals/47/a47a012.pdf|title=Deep drilling at Vostok station, Antarctica: history and recent events}}&amp;lt;/ref&amp;gt; The station was temporarily closed from January 1962 to January 1963,&amp;lt;ref name=dubrovin&amp;gt;{{cite book |last1=Dubrovin and Petrov |first1=L.

In 1974, when British scientists in Antarctica performed an airborne ice-penetrating [[radar]] survey and detected strange radar readings at the site, the presence of a liquid, freshwater lake below the ice did not instantly spring to mind.&amp;lt;ref&amp;gt;{{cite journal |last=Oswald |first=G.

In 2019, the Russian government began construction on a new, modern station building to replace the aging facilities.

Of official weather stations that are currently in operation, Vostok is the coldest on Earth in terms of mean annual temperature. However, it has been disputed that Vostok Station is the coldest-known location on Earth. The now inactive [[Plateau Station]], located on the central Antarctic plateau, is believed to have recorded an average yearly temperature that was consistently lower than that of Vostok Station during the 37-month period that it was active in the late 1960s,&amp;lt;ref&amp;gt;{{cite web|url=http://traverse.npolar.no/expedition-diary/archive/2007/12/22/discovering-historic-plateau-station|title=Discovering historic Plateau Station|access-date=30 December 2007|author=Mary Albert|publisher=Norwegian-U.S. Scientific Traverse of East Antarctica}}{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }}&amp;lt;/ref&amp;gt; and satellite readings have routinely detected colder temperatures in areas between Dome A and Dome F.{{citation needed|date=December 2018}} The most recent record set was the October record low, set on 1 October 2021.&amp;lt;ref&amp;gt;{{cite web |url=https://www.ogimet.com/cgi-bin/gsodres?lang=en&amp;amp;mode=0&amp;amp;state=United+K&amp;amp;ind=89606&amp;amp;ord=REV&amp;amp;ano=2021&amp;amp;mes=10&amp;amp;day=20&amp;amp;ndays=50 |title=  Vostok (Antarctica) |publisher=Ogimet |access-date= October 22, 2021}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

Vostok is one of the [[Pole of Cold|coldest places on Earth]].

&lt;br /&gt;
Though unconfirmed, it has been reported that Vostok reached a temperature of {{cvt|-91|C}} on 28 July 1997.&amp;lt;ref&amp;gt;{{cite web| year=2000|last=Liang |first= Yong Li |url=http://hypertextbook.com/facts/2000/YongLiLiang.shtml| title=Coldest Temperature on Earth| work=The Physics Factbook| access-date=2 September 2007}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The warmest recorded temperature at Vostok is {{cvt|-14.0|C}}, which occurred on 5 January 1974.&amp;lt;ref name=&amp;quot;poguda&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
In addition to the extremely cold temperatures, other factors make Vostok one of the most difficult places on Earth for human habitation:&lt;br /&gt;
*An almost complete lack of [[Humidity|moisture]] in the air.&lt;br /&gt;
*An average windspeed of {{convert|5|m/s|mph kph}}, sometimes rising to as high as {{convert|27|m/s|mph kph}}.&lt;br /&gt;
*The lack of [[oxygen]] in the air because of its [[altitude sickness|high elevation]] at {{convert|3488|m|abbr=off}}.&lt;br /&gt;
*A higher [[ionization]] of the air.&lt;br /&gt;
*A [[polar night]] that lasts approximately 120 days, from late April to mid-August, including 85 continuous days of civil polar night (i.e. too dark to read, during which the sun is more than 6 degrees below the horizon.)&amp;lt;ref&amp;gt;{{cite web|url=http://www.timeanddate.com/sun/antarctica/vostok-station?month=5&amp;amp;year=2015|title=Sunrise and sunset times in Vostok Station, May 2015|website=www.timeanddate.com}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
[[Acclimatization]] to such conditions can take from a week to two months and is accompanied by [[headache]]s, eye twitches, ear pains, nose bleeds, perceived suffocation, sudden rises in [[blood pressure]], loss of sleep, reduced [[appetite]], [[vomiting]], joint and muscle pain, arthritis, and weight loss of {{cvt|3-5|kg|0}} (sometimes as high as {{cvt|12|kg|0}}).{{citation needed|date=March 2016}}&lt;br /&gt;

== Ice core drilling ==&lt;br /&gt;
[[Image:Vostok 420ky 4curves insolation.jpg|thumb|right|310px|420,000 years of ice core data from Vostok, Antarctica, research station. Current period is at left. From bottom to top: [[insolation]] at 65°N due to [[Milankovitch cycles]] (connected to &amp;lt;sup&amp;gt;18&amp;lt;/sup&amp;gt;O); &amp;lt;sup&amp;gt;18&amp;lt;/sup&amp;gt;O isotope of [[oxygen]]; levels of [[methane]] (CH&amp;lt;sub&amp;gt;4&amp;lt;/sub&amp;gt;); relative temperature; levels of [[carbon dioxide]] (CO&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;)]]&lt;br /&gt;
&lt;br /&gt;
In the 1970s, the [[Soviet Union]] drilled a set of cores {{convert|500|–|952|m}} deep. These have been used to study the oxygen isotope composition of the ice, which showed that ice of the last glacial period was present below about 400 metres&amp;#039; depth. Then three more holes were drilled: in 1984, Hole 3G reached a final depth of 2,202&amp;amp;nbsp;m; in 1990, Hole 4G reached a final depth of 2,546&amp;amp;nbsp;m; and in 1993 Hole 5G reached a depth of 2,755&amp;amp;nbsp;m; after a brief closure, drilling continued during the winter of 1995. In 1996 it was stopped at depth 3,623 m, by the request of the [[Scientific Committee on Antarctic Research]] that expressed worries about possible contamination of [[Lake Vostok]]. This [[ice core]], drilled collaboratively with the French, produced a record of past environmental conditions stretching back 420,000 years and covering four previous glacial periods. For a long time it was the only core to cover several glacial cycles; but in 2004 it was exceeded by the [[EPICA]] core, which, whilst shallower, covers a longer time span. In 2003 drilling was permitted to continue, but was halted at the estimated distance to the lake of only 130&amp;amp;nbsp;m.&lt;br /&gt;
&lt;br /&gt;
The ancient lake was finally breached on 5 February 2012 when scientists stopped drilling at the depth of 3,770 metres and reached the surface of the subglacial lake.&lt;br /&gt;
&lt;br /&gt;
The [[Ice core brittle zone|brittle zone]] is approximately between 250 and 750 m and corresponds to the [[Last Glacial Maximum]],&amp;lt;ref name=Lipenkov&amp;gt;{{cite journal |vauthors=Lipenkov VY, Salamatin AN, Duval P |title=Bubbly-ice densification in ice sheets: 11.

&lt;br /&gt;
Although the Vostok core reached a depth of 3,623&amp;amp;nbsp;m the usable climatic information does not extend down this far. The very bottom of the core is ice refrozen from the waters of Lake Vostok and contains no climate information. The usual data sources give proxy information down to a depth of 3,310&amp;amp;nbsp;m or 414,000 years.&amp;lt;ref&amp;gt;[http://www.ncdc.noaa.gov/paleo/icecore/antarctica/vostok/vostok_data.html Vostok Ice Core Data] www.ncdc.noaa.gov, 2005-12-22. Retrieved 27 March 2007.&amp;lt;/ref&amp;gt; Below this there is evidence of ice deformation. It has been suggested that the Vostok record may be extended down to 3,345&amp;amp;nbsp;m or 436,000 years, to include more of the interesting MIS11 period, by inverting a section of the record.&amp;lt;ref&amp;gt;{{cite journal |last1=Raynaud |first1=Dominique |last2=Barnola |first2=Jean-Marc |last3=Souchez |first3=Roland |last4=Lorrain |first4=Reginald |last5=Petit |first5=Jean-Robert |last6=Duval |first6=Paul |last7=Lipenkov |first7=Vladimir Y. | title= Palaeoclimatology: The record for marine isotopic stage 11 | journal=Nature | volume=436 | year=2005 | pages=39–40| doi=10.1038/43639b | pmid=16001055 | issue=7047 | bibcode= 2005Natur.436...39R | s2cid= 4363692 }}&amp;lt;/ref&amp;gt; This then produces a record in agreement with the newer, longer EPICA record, although it provides no new information.&lt;br /&gt;
