Sea lanes are specific routes on the ocean that ships use to travel from one port to another. These routes are important for international trade, as they connect different countries and allow for the efficient movement of goods. Sea lanes are often marked by navigational aids and are monitored to ensure safe passage for vessels. The most significant sea lanes are located in busy maritime regions, such as the Strait of Malacca and the Panama Canal. These areas experience high traffic due to their strategic locations, making them vital for global commerce. Proper management of sea lanes helps prevent accidents and ensures the security of maritime trade.
