For a ridge in Alaska, see Alpha Ridge, Alaska

The Alpha Ridge is the principal tectonic feature under the Arctic Ocean between the Canada Basin (off the Ellesmere Island) and the Lomonosov Ridge. It was discovered in 1963. The highest elevation is about 2.7 km over the ocean floor, it is 200-450 km wide. The Alpha Ridge, Lomonosov Ridge, and Nansen-Gakkel Ridge are the three major ranges that divide the Arctic Ocean floor,^[1] running renerally parallel to each other.

The 1983 Canadian Expedition to Study the Alpha Ridge (CESAR) seemed to establish that the Alpha Ridge is an extension of the continent from the Ellesmere Island and hence there is a possibility that Canada may lay claim the resource rights for the region, in paricular for petroleum, according to the United Nation's Law of the Sea. However there is no final conslusion of the issue, and part of the research planned for the European Drilling Research Icebreaker (Aurora Borealis) was drilling of the Alpha Ridge to collect more immediate data.^[2] Pumpjack pumping an oil well near Lubbock, Texas Ignacy Łukasiewicz - inventor of the refining of kerosene from crude oil. ...
