Study reveals how long-distance ocean migrators reorient using compass headings in mid-ocean
By
Nicole Esteban
Summary
This scientific research article investigates how animals navigate during long-distance ocean migrations to specific targets. The authors developed and deployed tracking technology to study compass heading and mid-ocean reorientation behaviors in long-distance ocean migrators. The study addresses the long-standing mystery of animal navigation, building on over a century of research into how animals use celestial cues (like the sun) for compass heading, while also needing a map sense or goal-directed cues to estimate their position relative to their destination. The research provides empirical records of how these animals reorient themselves in the open ocean during migration.

Many animals can maintain a particular compass heading by using the sun or other celestial compass
In addition to a compass sense, animals also need a mechanism to estimate their position with respect to the goal, for example, through a map sense or the use of cues emanating from the goal
