The PanStar Acro entered Arctic waters on Monday, beginning the first government-backed trial voyage through the Northern Sea Route by a South Korean container ship. The Ministry of Oceans and Fisheries said the vessel reached the Arctic region around 8 a.m. Korea time, nine days after departing Busan New Port on Aug. 22. It is carrying 737 twenty-foot-equivalent units (TEUs), a standard measure of container capacity, and is expected to leave the Arctic Ocean around Sept. 7–8.
