Translation: The caption says: "We can find out about the Lomonosov spine/ridge through the use of an x-ray machine." Explanation: It's a play on words. The extension of the so-called "Lomonosov Ridge" into the Arctic Ocean is the basis for Russia's recent claim to a large portion of the Arctic sea floor. The Russian word for "ridge" also means "spine". Lomonosov -- pictured in the cartoon -- was a 18th century scientist-writer (something like a Russian Benjamin Frankin, a Russian renaissance man).
