Subsea Cable Surveys Are Converging on the Same Behavioral Signature
Four Chinese state-owned research vessels conducted surveys above five Pacific cable systems this summer. A Russian oceanographic vessel loitered above six transatlantic cable systems for more than 550 hours combined. A Liberia-flagged bulk carrier spent approximately 71 hours inside the Finland-Estonia subsea cable corridor.
Why it matters: This matters for the theme of critical infrastructure, as the repeated behavioral signatures across different regions indicate systematic mapping of subsea cables.
