The exploration of the Arctic Ocean has always been a difficult and dangerous business. People who have studied the ocean in different periods are real heroes, they deserve appreciation and respect. At the end of the XVIII century. According to the results of the sailing of the Russian expedition Vitus Bering, a reliable map of the western part of the ocean was compiled. The first information about the nature of circumpolar regions was obtained only at the end of the 19th century. thanks to the drift of the vessel of the Norwegian explorer Fridtjof Nansen, and later the navigation of the Russian polar explorer Georgy Sedov.
In 1932, the Russian scientist Otto Schmidt led an expedition on the Sibiryakov icebreaker, during which depth measurements were made, a thickness of the ice cover was established in different parts of the ocean, and observations were made of the weather.
Nowadays, aviation and space vehicles are used for ocean exploration. Instruments installed on these apparatuses provide information on changes in the state of the atmosphere over the oceanic space and on the directions of movement of ocean ice. Today, I have already unraveled the secrets of the nature of the Arctic Ocean, but many of them still have to be revealed.
