Denmark used Russian research data to substantiate its application for the expansion of its Arctic shelf, TASS reports citing Russian Minister of Natural Resources and Environment Sergei Donskoi.

"We have questions for Denmark and are currently discussing the issue with them. Last month, our experts went to Copenhagen to present our perspective and our comments regarding their claim. <…> We had our say about the claim and the points where we have significant differences of opinion. Our view is that Denmark's application is mainly based on Russia's geological data that we published in open sources," Mr Donskoi commented.

In 2014, Denmark and Greenland, an autonomous administrative division within the Danish Realm, announced its claim to the North Pole and 895,000 sq km of the Arctic Ocean seabed, according to TASS. They declared that the Lomonosov Ridge on the ocean floor is an extension of the Greenland Shelf. This is Denmark's fifth application. Three earlier submissions were partially accepted by the commission. The country has already spent $50 million on research.
