The Arctic Ocean

The Arctic Ocean is the smallest and northernmost of the world's five oceans, located around the North Pole. It is characterized by icy waters, often covered with sea ice that varies seasonally. The ocean is bordered by North America, Eurasia, Greenland, and parts of Canada and Russia. Despite its cold temperatures, it supports diverse marine life such as polar bears, seals, and whales. The Arctic Ocean plays a crucial role in Earth's climate system by regulating temperature and climate patterns through its ice cover and ocean currents. Its health is vital for the global environment, especially amid climate change concerns.
