The Arctic and Antarctic seas are the primary seas that freeze.
According to available information, sea ice, which is frozen seawater floating on the ocean's surface, forms extensively in both the Arctic and Antarctic regions. The lack of sunlight in these areas results in atmospheric conditions cold enough for the ocean water to freeze during winter months.
Here's a breakdown:
- Arctic Ocean: Surrounding the North Pole, large portions of the Arctic Ocean freeze each winter, creating vast expanses of sea ice.
- Southern Ocean (Antarctic): Encircling Antarctica, the Southern Ocean also experiences significant sea ice formation during the Antarctic winter.
