The Arctic Ocean is the coldest ocean.
According to our reference, the Arctic Ocean is even colder than the waters surrounding Antarctica. This is because the Arctic Ocean consistently has sea ice, even during the summer months. This constant presence of ice keeps the surface temperature of the water near the freezing point of seawater.
| Ocean | Temperature Characteristics |
|---|---|
| Arctic Ocean | Coldest; Consistent sea ice, even in summer. |
| Antarctic Ocean | Very cold, but generally warmer than the Arctic. |
Therefore, due to the perpetual ice cover, the Arctic Ocean maintains the lowest average temperature compared to other oceanic regions.
