Five Flags on the Seabed

In 2007, a Russian submarine planted a titanium flag on the seabed beneath the North Pole, 4,261 meters underwater. The gesture was dismissed as theater. The documents that followed were not.

I’ve read the UN continental shelf submissions from Russia (2015 and 2023), Denmark/Greenland (2014), and Canada (2019 and 2022), the US extended continental shelf report (2024), the Congressional Research Service’s 98-page analysis updated July 2025, Japan’s official Arctic policy from the Cabinet Office, China’s Arctic white paper (2018), Brazil’s PROANTAR Antarctic program documentation, and the DoD Arctic Strategy (2024). Here is what the primary sources say about who owns the top of the world.

The UN Convention on the Law of the Sea (UNCLOS) gives coastal states sovereign rights over natural resources on their continental shelves — up to 200 nautical miles from their coastlines, or farther if they can prove the shelf extends geologically. A state that wants to claim the seabed beyond 200 miles must submit scientific evidence to the Commission on the Limits of the Continental Shelf (CLCS).

Russia, Canada, and Denmark have all submitted claims that overlap at the North Pole. The United States has not ratified UNCLOS and therefore cannot submit a formal claim, though it has mapped its extended continental shelf and published the results.

The claims overlap because the Lomonosov Ridge — a submarine mountain range running 1,800 kilometers across the Arctic Ocean floor — passes near the Pole, and all three nations argue it is a natural extension of their continental shelf.

Russia

Russia’s 2015 revised submission to the CLCS claimed approximately 1.2 million square kilometers of Arctic seabed, including the Lomonosov Ridge, the Mendeleev-Alpha Rise, and portions of the Gakkel Ridge and Nansen Basin.

In 2023, the CLCS issued partial recommendations. It accepted Russia’s claims over the Mendeleev-Alpha Rise and parts of the Lomonosov Ridge. It rejected the Gakkel Ridge claim.

Russia’s Arctic Strategy 2035, which I read in the English translation provided by the U.S. Naval War College’s Russia Maritime Studies Institute, identifies the Northern Sea Route as a “nationally important transport corridor” and Arctic natural resources as essential to Russia’s economic future.

The CRS report notes that Russia has undertaken “a substantial Arctic military modernization program” including rebuilding Soviet-era bases, deploying new nuclear-powered icebreakers, and conducting military exercises north of the Arctic Circle.

Canada

Canada’s 2019 submission to the CLCS covers approximately 2.4 million square kilometers of Arctic seabed. The 2022 addendum extends the claim along the full Central Arctic Plateau — the Lomonosov Ridge, Alpha Ridge, and Mendeleev Rise.

The claim directly overlaps with Russia’s. Both countries argue the Lomonosov Ridge is a geological extension of their continental shelf. The resolution depends on where the ridge’s geological origin is classified — from the Siberian margin or the North American margin.

Canada and Denmark have an additional overlapping claim. In 2012, they reached a partial agreement on the Lincoln Sea boundary. The seabed claims in the Central Arctic remain unresolved.

Denmark (via Greenland)

Denmark’s 2014 submission on behalf of Greenland claims Arctic seabed extending from Greenland’s northern coast across the Lomonosov Ridge. It overlaps with both Russia’s and Canada’s claims.

This claim matters more than its size suggests, because Greenland is the reason the Arctic is in American domestic politics.

The Greenland problem

The CRS report — this is a Congressional Research Service document advising Congress, not a newspaper — documents the following:

  • Trump expressed interest in annexing Greenland on multiple occasions since 2019
  • The White House was, as of April 2025, “preparing an estimate of what it would cost the federal government to control Greenland as a territory”
  • U.S. intelligence agencies were directed in May 2025 to increase surveillance of Greenland’s independence movement
  • The Pentagon transferred operational responsibility for Greenland from USEUCOM to USNORTHCOM in June 2025
  • Denmark summoned the American ambassador, and France’s president visited Greenland in solidarity

The CRS report frames this within what it calls “Monroe Doctrine 2.0” — a strategy to enhance U.S. influence over the Western Hemisphere in preparation for a “spheres-of-influence world featuring three primary spheres led by the United States, Russia, and China.”

Greenland’s mineral deposits include rare earth elements critical to electronics and defense manufacturing. China has invested in Greenland mining projects. Greenland’s business minister told the Financial Times in May 2025: “We do want to partner up with European and American partners. But if they don’t show up I think we need to look elsewhere.”

China

China published its first Arctic white paper in 2018, declaring itself a “near-Arctic state” — a geographic claim that raised eyebrows, given that China’s northernmost point is 53°N, more than 1,500 kilometers south of the Arctic Circle.

The white paper introduced the concept of a “Polar Silk Road” — extending the Belt and Road Initiative into Arctic shipping routes. China now operates two icebreakers (Xuelong and Xuelong 2) and maintains a research station on Svalbard.

The Arctic Institute’s 2025 China Series, which I read in full, documents China’s expanding Arctic footprint: scientific research stations as dual-use infrastructure, investments in Greenland and Iceland mining, and growing participation in Arctic governance forums despite being a non-Arctic state.

The CRS report notes that “Russia-China cooperation” in the Arctic has increased since the Ukraine war, with joint naval exercises and China financing Russian Arctic LNG infrastructure after Western sanctions cut off other investment.

The United States

The US mapped its extended continental shelf and published the results in a 2024 report from the Ted Stevens Arctic Center. The mapped area covers seven regions, including the Arctic.

But the US has not ratified UNCLOS. This means it cannot submit a formal claim to the CLCS, and any claim it makes has no standing under international law as currently structured. The CRS report notes this fact repeatedly, in what reads as a sustained institutional nudge toward ratification.

The DoD Arctic Strategy (2024) identifies the Arctic as a domain of “strategic competition” and calls for enhanced military presence, infrastructure investment, and cooperation with Arctic allies.

NOAA’s Arctic Vision and Strategy (2025), which I also read, is primarily focused on climate science and maritime safety — a different institutional emphasis than the DoD document, both of which apply to the same geography.

Japan and Brazil

Japan’s official Arctic Policy, published by the Cabinet Office, identifies Japan as a major user of Arctic shipping routes and a participant in Arctic scientific research through its National Institute of Polar Research.

Brazil’s participation is Antarctic, not Arctic — through the PROANTAR program and the rebuilt Comandante Ferraz station. But Brazil participates in the Antarctic Treaty system, which has implications for how sovereignty claims work at the poles. The Antarctic Treaty suspends all territorial claims. No equivalent treaty exists for the Arctic.

That asymmetry matters. The Arctic is governed by UNCLOS — a framework designed for oceans, not for a ocean that used to be ice. As the ice retreats, the gap between the legal framework and the physical reality widens.

The pattern

In 1909, two men raced to plant flags at the North Pole on ice. In 2007, a submarine planted a flag on the seabed. In 2025, five nations were submitting geological surveys to a UN commission to determine who owns the rocks under the water under the ice that is melting.

The Peary-Cook controversy was about whether someone had stood at a geographic point. The current Arctic competition is about who controls the resources beneath a geographic region. The flags are the same gesture. The stakes are different by orders of magnitude.

Russia’s claim is backed by a submarine fleet and nuclear icebreakers. Canada’s claim is backed by geological surveys and legal filings. Denmark’s claim runs through Greenland, which the United States wants to annex. China calls itself a “near-Arctic state” and finances the infrastructure that Arctic nations won’t build. The United States has the military capacity but not the legal standing because it hasn’t ratified the treaty that governs the claims.

And the ice is still melting.
