The four oceans in the northern hemisphere are as follows: The ocean in the northern hemisphere is the Arctic Ocean.

The oceans on the earth are divided by land, forming four interconnected oceans: the Pacific Ocean, the Indian Ocean, the Arctic Ocean and the Atlantic Ocean. The Arctic Ocean is mainly located in the Arctic Circle, and all of them are located in the northern hemisphere.

All the oceans in the northern hemisphere are:

The Pacific Ocean lies between Asia, North America, South America, Antarctica and Oceania, the Indian Ocean between Asia, Africa, Oceania and Antarctica, the Arctic Ocean between Asia, Europe and North America, and the Atlantic Ocean between North America, South America, Europe, Africa and Antarctica.

The Arctic Ocean, also known as Arctic Ocean and Ice Water Ocean, is the smallest, shallowest and coldest ocean in the world, surrounded by Canada, Alaska, Russia, Norway, Iceland and other countries.

The Arctic Ocean is the ocean with the longest longitude span among the four oceans, covering an area of about 654.38+047,500 square kilometers, and it is the only uninhabited ocean in the world.

Arctic Ocean, also known as Arctic Ocean and Ice Water Ocean, is one of the four oceans of the earth and the smallest, shallowest and coldest ocean in the world.

Roughly centered on the Arctic Circle, it is located at the northernmost part of the earth, surrounded by Canada, Alaska, Russia, Norway, Iceland and Greenland (Denmark), and there is a narrow Bering Strait communicating with the Pacific Ocean. It is connected with the Atlantic Ocean through the Greenland Sea and many straits.

The Arctic Ocean is the longest ocean in the world and the only uninhabited ocean in the world. The area is only 654.38+047.5 thousand square kilometers, less than 654.38+00% of the Pacific Ocean.

Its depth is1097m, and its deepest point is 5527m. Ancient Greece once called it "the ocean facing Ursa major". 1845, named after the Geographical Society of Budapest, Hungary, translated into Arctic Ocean in Chinese.

Mbth Arctic comes from Greek, which means the ocean facing Ursa major. 20 12 On August 25th, the sea ice area of the Arctic Ocean reached the smallest in the observation history.
