Lomonosov Ridge

A Canadian scientific expedition, based out of Alert on Ellesmere Island, established an ice camp on 22 March 1979. The camp, with two other smaller camps, Snowsnake and Iceman lasted a few months with all remnants gone by 10 June 1979.[5]

In the 2000s, the geological structure of the ridge attracted international attention due to a 20 December 2001 official submission by the Russian Federation to the UN Commission on the Limits of the Continental Shelf in accordance with the United Nations Convention on the Law of the Sea (article 76, paragraph 8). The document proposed establishing new outer limits for the Russian continental shelf, beyond the previous 200-nautical-mile (370 km; 230 mi) zone, but within the Russian Arctic sector.[6] The territory claimed by Russia in the submission is a large portion of the Arctic reaching the North Pole.[7] One of the arguments was a statement that the underwater Lomonosov Ridge and Mendeleev Ridge are extensions of the Eurasian continent.[1] In 2002 the UN Commission neither rejected nor accepted the Russian proposal, recommending additional research.[6]

Danish scientists hope to prove that the ridge is an extension of Greenland,[8] rather than an extension of Canada's adjacent Ellesmere Island, and Denmark became another claimant to the area in 2014.[9] Canada, also a claimant, asserts that the ridge is an extension of its continental shelf. In April 2007, Canadian and Russian scientists were sent to map the ridge as a possible precedent for determining sovereignty over the area.[1] In late June 2007, Russian scientists reiterated their claim that the ridge is an extension of Russia's territory,[10] and in 2011 a Russian scientist ignored Canada's claim, instead saying that Russia and Denmark claim different parts of the ridge and the claims are not conflicting.[11] Other sources indicate that some areas are disputed.[12]

Canada is expected to make further claims.[13] Denmark and Russia have agreed to follow certain procedures when making claims.[14] If the Danish claims are accepted by the Commission in summer 2015,[9] the distribution of areas may still be a matter of negotiation between claiming countries – a process which can take several years.[15] The rhetoric used in making claims is also subject to discussion.[16]

A 21-member UN arbitration panel is considering the competing claims, with the focus on the Lomonosov Ridge.[17]

In 2014 Denmark filed a claim with the UN Commission for a 895,000 square kilometres (346,000 sq mi) area around the Lomonosov Ridge,[9] using paragraphs 4, 5 and 6 of Article 76.[21][22] The connection between Greenland and Lomonosov is stated as going through the Lincoln shelf (400 metres or 1,300 feet below the Lincoln Sea, between the Wandel Sea in the east and Cape Columbia, Canada in the west), which was pushed up when Greenland moved northwards during the late Paleozoic, Paleocene and Eocene time frames.[2][23] Some rocks from the ridge are similar to those found in Ellesmere, Greenland, Scandinavia and United Kingdom.[2] Connectivity between land and the ridge may be defined from the Foot of the Slope.[15] From the ridge foot claims are made out to 60 nautical miles (110 km; 69 mi) ("Hedberg formula"), or 100 nautical miles (190 km; 120 mi) where the sedimentary layer is more than 1 nautical mile (1.9 km; 1.2 mi) deep ("Gardiner formula", 1% of the distance).[2][15]
