Boris Vilkitsky

In 1913—1915 he led the Arctic hydrographic expedition on the ships "Taimyr" and "Vaigach" with the purpose of further exploration of the Northern Sea Route.

In 1914–1915, Vilkitsky's expedition made the first through voyage from Vladivostok to Arkhangelsk, discovered Novopashenniy Island (now Zhokhov Island), and described the eastern coastline of the territory he named 'Emperor Nicholas II Land'.

He was awarded the prestigious Constantine Medal by the Russian Geographical Society for his endeavours.

[2] In 1918, Vilkitsky was appointed head of the first Soviet hydrographic expedition, which never took place due to its seizure by the North Russia intervention in Arkhangelsk.

In 1923 and 1924, Vilkitsky led commercial expeditions in the Kara Sea at the invitation of the Soviet foreign trade organizations.
