Polar bear in Manitoba, Canada. November 2004. Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its ...
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans.
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
An extreme exception to this occurred during a rapid transit to Pt. Barrow, Alaska between January 29 and February 11, 1981. While traversing 1000 miles of sea ice, Polar Sea was able to break through ice up to 40 ft thick. [7] Polar Sea alongside her sister ship Polar Star (WAGB-10) near McMurdo Station, Antarctica.

The ice extent trends from 1979 to 2002 have been a statistically significant Arctic sea ice decrease of −2.5% ± 0.9% per decade during those 23 years. [7] Climate models simulated this trend in 2002. [8] The September minimum ice extent trend for 1979–2011 declined by 12.0% per decade during 32 years. [9]
