Briefly describe the Arctic Ocean

The Arctic Ocean is the smallest ocean on Earth, located completely in the northern hemisphere, between Eurasia and North America. The ocean area is 14.75 million km2, the volume of water is 18.07 million km3. The average depth is 1225 m, the deepest is 5527 m in the Greenland Sea. The majority of the bottom topography of the Arctic Ocean is occupied by the shelf (more than 45% of the ocean floor) and the underwater margins of the continents (up to 70% of the bottom area). The ocean is usually divided into three vast water areas: the Arctic basin, the North European basin, and the Canadian basin. Due to the polar geographical position, the ice cover in the central part of the ocean remains throughout the year, although it is in a mobile state
