This video, adapted from material provided by the ECHO partners, illustrates some of the methods that people from communities across the globe have used to navigate on the open ocean. European and American sailors relied on navigational instruments. Polynesian travelers used traditional techniques based on celestial navigation and on their observations of clouds, winds, birds, and other phenomena. And the Iñupiaq people of northern Alaska rely on their centuries-old knowledge of their environment to find their way while hunting and fishing.
