POLAR SEA Meaning and
Definition
-
A polar sea refers to a large body of saltwater found in the Earth's polar regions, principally around the North Pole (Arctic Ocean) and the South Pole (Southern Ocean). It is different from ordinary seas as it is primarily encompassed by ice and has unique ecological and climatic conditions.
Characterized by extremely low temperatures, polar seas are covered in year-round ice sheets, known as sea ice, that often extend for miles. This ice cover varies in thickness and extent, with the Arctic Ocean experiencing significant seasonal melting and refreezing. The Southern Ocean, though less navigable due to extreme storms and icebergs, is mainly ice-free during the summer.
Polar seas possess distinct ecosystems and are home to a variety of marine wildlife adapted to cold environments, including polar bears, seals, whales, penguins, and various fish species. They also play a vital role in regulating Earth's climate, acting as a reservoir for cold water that influences ocean temperature and currents.
Furthermore, these seas have attracted scientific interest due to their potential for natural resource exploration, including oil and gas reserves. Additionally, they serve as key transportation routes for international trade, particularly the Northern Sea Route and the Northwest Passage. Considered delicate ecosystems, polar seas and their biodiversity require careful preservation and management to mitigate the effects of climate change and human activity.

The English word "polar" began to be used in the 16th century to describe things connected to the Earth's polar regions. It is primarily used to refer to the areas around the North and South Poles.
2. Sea: The word "sea" originated from the Old English word "sǣ", which referred to a large body of saltwater. The Old English word is believed to have derived from the Proto-Germanic word "*saiwiz", meaning "lake" or "sea".
