Researchers Confirm 19,940-Mile Longest Ocean Route, Dominated by the Pacific

1 articles · Updated · spacedaily.com · May 30

Summary

  • 32,090 kilometers is the longest straight-line path a vessel can sail without landfall, tracing a great-circle route from Pakistan to northeastern Russia and crossing mostly the Pacific.
  • 2018 work by Rohan Chabukswar and Kushal Mukherjee used NOAA’s ETOPO1 topographic model to verify a route first informally suggested by Reddit user Patrick Anderson.
  • The line threads between Madagascar and Africa, passes the Drake Passage, then spans the Pacific basin—whose uninterrupted size makes the route possible in a way no other ocean can match.
  • 11,241 kilometers is the longest comparable straight path on land, from eastern China to Portugal across 15 countries, underscoring how fragmented Earth’s continents are.
  • 155 million square kilometers of Pacific Ocean—larger than all global land area combined—help explain why nearly half of Earth’s ocean surface sits in a single basin.
