Detailed explanation-2: -The Arctic Ocean is the smallest and shallowest of the world’s five major oceans.

Detailed explanation-3: -The Arctic Ocean is the shallowest (mean depth 1361 m) and has significantly larger continental shelves than other oceans. The deep central Arctic Ocean Basin consists of four abyssal plains separated by submarine ridges. The abyssal plains make 12 %, while ridges make 16 % of the total area of the Arctic Ocean.

Detailed explanation-4: -The Continental Shelf is the shallowest part of the ocean. It is an extension of land that is submerged under the ocean.

Detailed explanation-5: -Although the Arctic Ocean is by far the smallest of Earth’s oceans, having only a little more than one-sixth the area of the next largest, the Indian Ocean, its area of 5, 440, 000 square miles (14, 090, 000 square km) is five times larger than that of the largest sea, the Mediterranean.
