Vostok, Lake

Lake Vostok (vä´stôk), c.3,900 sq mi (10,000 sq km), c.155 mi (250 km) long and 30 mi (50 km) at its greatest width, in East Antartica beneath the remote Vostok research station. One of the largest subglacial lakes in Antarctica, the presumably freshwater lake is located beneath c.2.5 mi (4 km) of ice, and is 30 to 1,650 ft (10–500 m) deep. It is divided into north and south basins, which are separated by an underwater ridge. Since the lake was discovered in 1996, scientists have speculated it may hold microbes that have been isolated for millions of years, but have not drilled down to its waters for fear of contaminating them. Cores drilled to within c.500 ft (150 m) of the lake have returned ice samples some 420,000 years old; drilling reached the lake's surface in 2012.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
