The sun rose over the horizon on March 9. We felt overjoyed after a six-month polar night, and the polar day began 20 days later.
We knew that the station would continue its work, and that a new crew, headed by Belov, Ph. D. (Geography), would arrive soon.
It took our station 12 months to drift 2,068 kilometers along a tricky route in a little-studied section of the Arctic Ocean and near the Pole of Inaccessibility. Therefore our research data proved highly important, especially for studying eastern Arctic nature.
The North Pole 7 station's drift confirmed a conjecture that the routes of the Central Polar Basin's ice formations are usually affected by local winds. The ice-floe's drift speeds tended to fluctuate throughout its 12-month journey. In summer, especially in August, the ice-floe attained maximum speeds, sometimes drifting at one kph daily. In winter, it drifted less than one kilometer per day
Meteorologists conducted about 4,000 observations. This data facilitated navigation along the Northern Sea Route. Observations involving about 800 radio-balloon probes helped study processes in various atmospheric layers over the Arctic.
Chernigovsky, Ph. D. (Geography), and meteorologist Rogachov conducted over 9,000 observations to monitor solar radiation levels near the surface of the ice. They also evaluated its impact on ice-and-snow layers and on the under-ice ocean waters.
Hydrologist Blinov conducted oceanological research that made it possible to specify the ocean-bed relief, the composition of soils and water masses, to study the animal world, to monitor ice-melting and ice-expansion processes and to watch an ice-floe appear on the surface. Contrary to initial estimates, the ocean-bed relief in the drift sector turned out to be more rugged and complex. The eastern slopes of an uplift, located east of Lomonosov Ridge, were steeper than western ones. On some days, ocean depths near the eastern slopes fluctuated between 1,600 and 3,000 meters, with the ice-floe drifting 10–12 kilometers per day.
Geophysicists Ignatov, Kuchuberia and Borisov often recorded geomagnetic and ionospheric aberrations caused by greater solar activity.
The North Pole 7 station closed on April 11, 1959 after its ice-floe shrank to a length of 700, with a width of 450 meters.
