Though the Southern Ocean does not have a landmass bordering it to the north, it is treated as a separate oceanic division due to the difference in water properties of the ocean south of the 60° S latitude. It is a deep ocean with depth ranging between 4,000 and 5,000 m across most parts.
What is the Arctic Ocean?
The Arctic Ocean is located in a polar climatic zone characterized by frigid year-round temperatures. Long hours of darkness engulf the ocean during winters and summers are characterized by continuous daylight.

Plant life in the Arctic Ocean is scarce except for abundant volumes of phytoplanktons. The Lion’s mane jellyfish and the banded gunnel are among the few species of marine creatures inhabiting the Arctic Ocean’s waters. The ocean bed also hosts petroleum and natural gas fields, polymetallic nodules, and placer deposits.
