Russia’s 511-Billion-Barrel Find in Antarctica Tests the Antarctic Treaty

Russia says seismic surveys off Antarctica’s Weddell Sea identified about 511 billion barrels of oil, a claim that could challenge the Antarctic Treaty’s mining ban by blurring science and prospecting. The work, conducted by Rosgeo aboard the Akademik Alexander Karpinsky, has raised concerns in London about whether such data could enable future extraction if treaty safeguards weaken, and about Moscow’s expanding footprint in a matter where seven countries claim parts of the continent. No violation has been proven, and Article VII allows inspections, but the next Antarctic Treaty Consultative Meeting is expected to weigh tighter transparency on seismic activity; for now no drilling has occurred.
