Drifting ice station

A drifting ice station is a temporary or semi-permanent facility built on an ice floe. During the Cold War the Soviet Union and the United States maintained a number of stations in the Arctic Ocean on floes such as Fletcher's Ice Island for research and espionage, the latter of which were often little more than quickly constructed shacks. Extracting personnel from these stations proved difficult and in the case of the United States, employed early versions of the Fulton surface-to-air recovery system. Soviet and Russian-staffed drifting ice stations are research stations built on the ice of the high latitudes of the Arctic Ocean. They are important contributors to exploration of the Arctic. The stations are named "North Pole" (NP; Северный полюс, СП), followed by an ordinal number: North Pole-1, etc. NP drift stations carry out the program of complex year-round research in the fields of oceanology, ice studies, meteorology, aerology, geophysics, hydrochemistry, hydrophysics, and marine biology. On average, an NP station is the host for 600 to 650 ocean depth measurements, 3500 to 3900 complex meteorology measurements, 1200 to 1300 temperature measurements and sea water probes for chemical analysis, and 600 to 650 research balloon launches. Magnetic, ionosphere, ice and other observations are also carried out there. Regular measurements of the ice floe coordinates provide the data on the direction and speed of its drift. The modern NP drifting ice station resembles a small settlement with housing for polar explorers and special buildings for the scientific equipment. Usually an NP station begins operations in April and continues for two or three years until the ice floe reaches the Greenland Sea. Polar explorers are replaced yearly. Since 1937 some 800 people were drifting at NP stations. There are two groups of NP stations: stations, drifting on the pack ice (i.e. relatively thin and short-lived ice): NP-1 through NP-5, NP-7 through NP-17, NP-20, NP-21 stations, drifting on ice islands (glacier fragments, that were split from the shore): NP-6, NP-18, NP-19, NP-22.

Franz Josef Land

Franz Josef Land (Zemlya Frantsa-Iosifa; Fridtjof Nansen Land) is a Russian archipelago in the Arctic Ocean. It is inhabited only by military personnel. It constitutes the northernmost part of Arkhangelsk Oblast and consists of 192 islands, which cover an area of , stretching from east to west and from north to south. The islands are categorized in three groups (western, central, and eastern) separated by the British Channel and the Austrian Strait. The central group is further divided into a northern and southern section by the Markham Sound.

Icebreaker

An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice.
