Ship Routes (IMAGE) American Geophysical Union Caption This is a map of ships crossing the Indian Ocean and surrounding seas during June 2012. Most ships crossing the northern Indian Ocean follow a narrow, nearly straight track around 6 degrees North between Sri Lanka and the island of Sumatra. East of Sumatra, ships travel southeast through the Strait of Malacca, rounding Singapore and extending northeast across the South China Sea. Aerosol particle emissions in these shipping lanes are ten times or more greater than in other shipping lanes in the region, and are among the largest globally.
