Study on Navigation Environment of Arctic Northeast Passage from 2005 to 2015
摘要
Abstract
Sea ice is one of the main factors that restricts the opening of the Arctic Passage. The rapid shrinking of the Arctic Sea ice makes it possible for the opening of the Northeast Passage. Based on the concentration and type of sea ice, this paper divided the navigation environment into four levels, made the navigation environmental maps of the Arctic Route, and analyzed the changes of navigation environment of four sea areas along the Arctic Northeast Passage from 2005 to 2015. The results show that the Chukchi Sea has the longest navigable period compared with other seas, which lasts from the beginning of July to the mid-to-late November. The annual trends of the East Siberian Sea are similar, while the navigable period extends slightly in Laptev Sea in recent years and navigation conditions of the Kara Sea are mainly affected by the sea ice located in its northeast. The navigable period of these three seas is from August to the beginning of October. The condition of East Siberian Sea, Laptev Sea and Severnaya Zemlya determines the opening time of the Northeast Passage in August and September.关键词
