The Brusilov expedition (Russian: Экспедиция Брусилова) was a Russian maritime expedition to the Arctic led by Captain Georgy Brusilov, which set out in 1912 to explore and map a route from the Atlantic Ocean to the Pacific via a northeast passage known as the Northern Sea Route. The expedition was ill-planned and ill-executed by Brusilov[according to whom?], and disappeared without a trace. Earlier searches were unsuccessful, and the fate of the ship and its crew is still not known.
One of the members of the expedition was the second Russian woman to go to the Arctic, Yerminia Zhdanko, a 22-year-old nurse and daughter of a general of the Russo-Japanese War.
