Zhokhov Island is an island in the East Siberian Sea, situated 128 km north east of Novaya Sibir Island, the easternmost of the New Siberian Islands. Administratively the island belongs to the Yakutia administrative division of Russia.

Geography

Zhokhov Island is part of the De Long group. The nearest island is Vilkitsky Island, the southernmost island of the group. Zhokhov is in length and has an area of. The highest point of the island is.
Although the island itself is unglaciated, the sea surrounding Zhokhov Island is covered with fast ice, even during the summer, and the climate is severe.

Geology

Zhokhov Island is an eroded late Cenozoic stratovolcano. Deeply cut seacliffs expose alternating flows of massive and blister lava, agglomerate and tuff. The exposed throat of this volcano is filled with columnar jointed basalts. The surrounding volcanic edifice consists of interlayered picrite–olivine basalts lava flows and beds of volcanic ash containing large volcanic bombs. The basalt lava flows range in age from 1.2 to 10 Ma according to K–Ar dating. The basalts contain xenoliths of sandstones, limestones, granites, syenites, and dolerites. Rare limestone xenoliths contain middle Carboniferous, tropical, marine invertebrate fossils.

Vegetation

Rush/grass, forb, cryptogam tundra covers the Zhokhov Island. It is tundra consisting mostly of very low-growing grasses, rushes, forbs, mosses, lichens, and liverworts. These plants either mostly or completely cover the surface of the ground. The soils are typically moist, fine-grained, and often hummocky.

History

Mesolithic humans occupied the island as early as 6000 BCE. Tools of stone, bone, antler, and ivory have been found, as well as wooden arrow shafts and a sledge runner. Animal remains suggest a culture dependent on the hunting of polar bears and reindeer. Evidence published in 2017 suggests that the early inhabitants of Zhokhov Island were among the first humans to selectively breed dogs. Findings indicate that larger dogs may have been bred for hunting and smaller dogs weighing to were bred for pulling sleds. DNA extracted from a 9,500-year-old dog, Zhokhov, named after the island, contributed significant genetic material to the Greenland Dog, the Alaskan Malamute and the Siberian Husky.
In modern times, Zhokhov Island was discovered by the 1910–1915 Russian Arctic Ocean Hydrographic Expedition under Boris Vilkitsky on the ships Vaygach and Taymyr. It was originally named Novopashenniy Island, after Piotr Alekseyevich Novopashenniy (1881–1950) Captain of icebreaker Vaygach, but in 1926 it was renamed after Lieutenant Alexey Zhokhov, a member of the expedition.

In popular culture

Zhokhov Island is mentioned in Stanley Kubrick's Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb as a place where the Russians built the doomsday device.
Ostrov Zhokhova is also mentioned in the Soviet "sad comedy" film by Georgii Danelia "Osennii Marafon". The film's "hero" Andrei Buzykin's daughter and her husband depart to take up a job in the weather station on Zhokhov Island, to Andrei's horror.
