Why the Panama Canal Lifts Ships 85 Feet Above the Ocean

How can a giant ship climb 85 feet above sea level without an elevator—or pumps? The Panama Canal is far more than a channel between two oceans. It is a gravity-powered system of locks, lakes, dams and gates that raises ships across Panama’s interior and lowers them back to sea level on the other side. In this documentary, you’ll follow the full journey from the Atlantic entrance through the Gatun Locks, Gatun Lake, the Culebra Cut, Pedro Miguel and Miraflores. You’ll see why a sea-level canal failed, how the original locks work without pumps, why Panamax ships were built around the canal’s dimensions, how the 2016 expansion opened a new lane for Neopanamax vessels, and why freshwater—not concrete—is the canal’s most important resource.
