Country Profile: Arctic Ocean

The Arctic Ocean is the smallest of the world's five ocean basins, situated primarily north of the Arctic Circle and bordered by Europe, Asia, and North America. Its geographic features include extensive continental shelves and a unique polar climate, which influences both the ecosystem and navigation routes. The shrinking polar ice pack has raised concerns about potential shipping disputes among Arctic coastal states, impacting both governance and economic interests in the region.

Geography

The Arctic Ocean covers an area of approximately 15.558 million square kilometers, making it slightly less than 1.5 times the size of the US. It is characterized by a polar climate, with extensive ice coverage for much of the year, and a coastline extending 45,389 km. The ocean's terrain includes features such as abyssal plains and continental shelves, with notable currents influencing its hydrology.

18.75 million cu km: Total volume of the Arctic Ocean, accounting for 1.4% of the world ocean's total volume.
-5,577 m: The Molloy Deep marks the lowest point in the ocean.
200 m: The depth at which light penetrates significantly, defining the euphotic zone.

Environment

The Arctic Ocean faces several environmental challenges, including biodiversity loss, water pollution, and thinning ice. These issues have been exacerbated by climate change, impacting marine ecosystems and species. Efforts are underway, such as a 16-year fishing ban in the Central Arctic Ocean established in 2017, to study and protect its ecological systems.

708 mt: Total catch in the Arctic fishery region in 2019, the smallest in the world.
2017: Year when a significant fishing ban was agreed upon by several nations to study ecological systems.

Government

The term "Arctic" derives from the Greek word arktikos, meaning "near the bear," which refers to prominent constellations in the northern celestial sphere. This nomenclature underscores the region's significance in cultural and scientific contexts.

Transportation

Transportation within the Arctic Ocean features a sparse network of air, ocean, river, and land routes. The Northwest Passage and the Northern Sea Route are crucial seasonal waterways that facilitate navigation in this remote region.
