Samudra Arktik: Perbedaan antara revisi

Central surface covered by a perennial drifting polar icepack that averages about 3 meters in thickness, although pressure ridges may be three times that size; clockwise drift pattern in the [[Beaufort Gyral Stream]], but nearly straight-line movement from the [[New Siberian Islands]] ([[Russia]]) to [[Denmark Strait]] (between [[Greenland]] and [[Iceland]]); the icepack is surrounded by open seas during the summer, but more than doubles in size during the winter and extends to the encircling landmasses; the [[ocean]] floor is about 50% [[continental shelf]] (the highest percentage of any ocean) with the remainder a central basin interrupted by three submarine ridges ([[Alpha Cordillera]], [[Nansen Cordillera]], and [[Lomonosov Ridge]])
