▲The '''Bellingshausen Sea''' is an area along the west side of the [[Antarctic Peninsula]] between 57°18'W and 102°20'W, west of [[Alexander Island]], east of [[Cape Flying Fish]] on [[Thurston Island]], and south of [[Peter I Island]] (there the southern ''Vostokkysten'').<ref>[http://data.aad.gov.au/aadc/gaz/display_name.cfm?gaz_id=107742 Australian Antarctic Data Centre, Antarctic Gazetteer: Bellingshausen Sea]</ref> InThe theBellingshausen southSea are,borders from west to east,the [[Eights Coast]], the [[Bryan Coast]], and [[Englishthe Coast]] (west part) of the [[WestEnglish AntarcticaCoast]]. To the west of Cape Flying Fish it joins the [[Amundsen Sea]].

Bellingshausen Sea has an area of {{convert|487,000|km2|abbr=on}} and reaches a maximum depth of {{convert|44704.5|mkm|sp=us}}.<ref>[https://web.archive.org/web/20110823210609/http://ostranah.com/lists/sea.php?id=18 Gazetteer «About countries»: Bellingshausen (sea)]</ref> It contains the undersea plain [[Bellingshausen Plain]].

The Antarctic Slope Current (ASC) is thought to originate in the Bellingshausen Sea as the result of a density front at the shelf break, rather than being wind-driven.<ref>{{Cite journal |last1=Thompson |first1=Andrew F. |last2=Speer |first2=Kevin G. |last3=Schulze Chretien |first3=Lena M. |date=2020-08-28 |title=Genesis of the Antarctic Slope Current in West Antarctica |url=https://authors.library.caltech.edu/records/a4mft-xj680/files/2020GL087802.pdf?download=1 |journal=Geophysical Research Letters |language=en |volume=47 |issue=16 |doi=10.1029/2020GL087802 |bibcode=2020GeoRL..4787802T |issn=0094-8276}}</ref>
