Bathymetry Arctic Ocean, in 4 editions.

continental shelf: The continental shelf (see Figure 1), a rather flat area of the sea floor adjacent to the coast that gradually slopes down from the shore to water depths of about that are typically less than 200 m (660 ft). Dimensions can vary: they may be narrow or nearly nonexistent in some places or extend for hundreds of miles in others. The waters along above the continental shelf are usually productive in both plant and animal life, both from sunlight and nutrients from ocean upwelling and terrestrial runoff. More than one quarter of the Arctic sea floor is continental shelf . The Eurasian shelf is very wide wide, extending out 1,500 km (930 mi) mi), and is the largest continental shelf in the World. world. The following are examples of features found on the continental shelf of the Arctic Ocean (see Figure 2).

Beaufort Shelf
Davis Sill
Chukchi Shelf
East Siberian Shelf
Kara Shelf
Laptev Shelf
Lincoln Shelf
continental slope: The continental slope (see Figure 1) is where the ocean bottom drops off more rapidly until it meets the deep-sea floor (abyssal plain) at about 3,200 depths exceeding 3,000 m (10,500 ft) water depth. (9,850 ft). The deep waters of the continental slope are characterized by cold temperatures, low light conditions, and very high pressures. Sunlight does not penetrate to these depths, having been absorbed or reflected in the water above. The continental slope can be indented by submarine canyons, often associated with the outflow of major rivers. Another feature of the continental slope are is alluvial fans fans, or cones of sediments carried sediments, that major rivers carry downstream to the ocean by major rivers and deposited deposit down the slope. The following are examples of features found on the continental slope of the Arctic Ocean (see Figure 2). 2):
Litke Trough
Novaya Zemlya Trough
Svyataya Anna Trough (Saint Anna Trough)
Voronin Trough
abyssal plains: The abyssal plains (see Figure 1), at depths of over 3,000 m (10,000 ft) and covering 70% of the ocean floor, are the largest habitat on earth. Sunlight does not penetrate to the sea floor, making these deep, dark ecosystems less productive than those along the continental shelf. Despite their name, these “plains” are not uniformly flat; they are interrupted by features like hills, valleys, and seamounts. The following are examples of features found on the abyssal plains of the Arctic Ocean (see Figure 2). 2):
Baffin Basin
Canada Basin
Fram/Amundsen Basin
Greenland Abyssal Plain
Iceland Basin
Makarov Basin
Molloy Deep; note - deepest point in the Arctic Ocean
Nansen Basin
Norwegian Basin
mid-ocean ridge: The mid-ocean ridge (see Figure 1), rising up 1) that rises from the abyssal plain, plain is an underwater mountain range, range over 64,000 km (40,000 mi) long, rising to reaching an average depth of 2,400 m (8,000 ft). Mid-ocean ridges form at divergent plate boundaries where two tectonic plates are moving apart and new crust is created by magma pushing up from the mantle. mantle creates new crust. Tracing their way around the global ocean, this system of underwater volcanoes forms the longest mountain range on Earth. Fracture Zones zones are linear transform faults that develop perpendicular to the line of the mid-ocean ridge ridge, which can offset the ridge line and divide it into segments. The following are examples of mid-ocean ridges found on the floor of in the Arctic Ocean (see Figure 2). 2):
Gakkel Ridge
Mohns Ridge
seamounts: undersea terrain features: The Abyssal Plain is commonly interrupted by a variety of undersea terrain features including seamounts , guyots , ridges , and plateaus .
Seamounts (see Figure 1) are submarine mountains at least 1,000 m (3,300 ft) high that are formed from individual volcanoes on the ocean floor. They are distinct from the plate-boundary volcanic system of the mid-ocean ridges, ridges because seamounts tend to be circular or conical. A circular collapse circular-collapse caldera is often centered at the summit, evidence of a magma chamber within the volcano. Flat topped seamounts are known as guyots . Long chains of seamounts are often fed by "hot "Hot spots" in the deep mantle. mantle often feed long chains of seamounts. These hot spots are associated with stationary plumes of molten rock rising from deep within the Earth's mantle. These hot spot The hot-spot plumes melt through the overlying tectonic plate as it moves and supplies magma to the active volcanic island at the end of the chain of volcanic islands and seamounts.
Flat-topped seamounts are known as guyots .
An undersea ridge is an elongated elevation of varying complexity and size, generally having steep sides.
An undersea plateau is a large, relatively flat elevation that is higher than the surrounding relief, with one or more relatively steep sides. Although submerged, these features can reach close to sea level.
The following are examples of seamounts undersea terrain features found on the floor of the Arctic Ocean (see Figure 2). 2):
Alpha Lomonosov Ridge
Chukchi Plateau
Iceland Plateau Gakkel Ridge
Lomonosov Alpha Ridge
Mendeleev Rise
Voring Plateau
Yermak Chukchi Plateau
ocean trenches: note - there are no oceanic trenches on the Arctic sea floor
atolls: note - there are no atolls found in the Arctic Ocean
