1.1 Definition Telemetry includes an array of techniques that allow remote monitoring, measurement and recording or reporting of information. It was first used in weather research and has expanded quickly to other disciplines. Relatively accurate measurements without direct observer participation allow some important research that was impossible to conduct in the past. This has an important implication for study of life history traits of species that migrates long-distances, such as sea turtles. The ocean habitat, wide distribution ranges and movement across political boundaries all create difficulties for direct study of sea turtle behavior. Telemetry can overcome these obstacles and is a cost-effect tool for behavioral ecology.
