Bellingshausen expedition

Bellingshausen's expedition encounters continuous Antarctic ice

Through falling snow the ice looked like white clouds — an ambiguous view that is still fuelling an argument about who first saw Antarctica.

The ice edge, January 1820

On the conventionally reconstructed civil date of 27 January 1820, the Imperial Russian Navy expedition led by Fabian Gottlieb von Bellingshausen reached roughly 69°21′S, 2°14′W and recorded continuous ice and ice formations to the south.

There were two sloops at the ice edge, not one: Bellingshausen commanded Vostok and Mikhail Lazarev commanded Mirny.

The continuous ice stopped further progress south. The expedition went on probing the ice edge in other directions rather than landing or claiming that it had discovered a continent.

A date that moves

Bellingshausen's narrative dates the encounter to 16 January Old Style, which converts to 28 January New Style. A later reconstruction of the nautical day shifts the civil date back to 15 January Old Style — 27 January New Style.

His own April 1820 report to the naval minister gives the position as 69°25′S, 2°10′W, slightly different from the figure Terence Armstrong reconstructed.

What he saw, and who saw land first

Armstrong's 1971 Polar Record article accepted 27 January and read the observed ice as the continental edge off Dronning Maud Land. Rip Bulkeley's 2019 retranslation argues the January observation was not a sighting of an ice coast, and places the first convincing Russian sighting in mid-February.

Bellingshausen did not clearly announce that he had seen Antarctica, and Armstrong explicitly notes that he made no such claim.

Three civil-calendar days later, on 30 January 1820, the British naval officer Edward Bransfield independently recorded Antarctic land at the peninsula.

Date disputed. Sources disagree; the research places it at 1820-01-27.

What the sources leave uncertain

Bellingshausen's narrative dates the encounter 16 January Old Style, equivalent to 28 January New Style. A later nautical-day reconstruction shifts the civil date back one day to 15 January Old Style/27 January New Style.
Terence Armstrong's 1971 Polar Record article accepted 27 January and interpreted the observed ice as the continental edge. Rip Bulkeley's 2019 retranslation argues that the January observation was not a sighting of an ice coast and places the first convincing Russian sighting in mid-February.
Bellingshausen did not clearly announce that he had seen Antarctica. Priority depends partly on whether seeing a continent-connected ice shelf without recognizing it counts over Bransfield's sighting and charting of visible land.
Because both the date conversion and the physical interpretation are contested, the event should not be presented as an undisputed first sighting.
