| Over the last 30 years, the global Argos system (CLS France/NOAA USA) has supported the increasing use of satellite telemetry to map the movements of sea turtles worldwide. Small water-tight transmitters have become increasingly smaller and more accurate with the introduction of GPS technology to recent tags. Positional data are collected by these tags and the data are transmitted via sensors on polar orbiting satellites that allow positions to be calculated by ground processing stations. The accuracy of the position is dependent on the type of tag used (Argos only or GPS/Argos) and the number of transmissions received by the satellite during its transit. Satellite telemetry can be a great tool for education and to foster conservation as internet technology allows for near real time mapping of the turtle¡¯s positions and can also be used to teach children more about the world by allowing them to plot these positions themselves as they follow the turtles journey. Creating maps from satellite telemetry can also show areas that might be important to sea turtles or ¡°hot spots¡± for resting and foraging which can help in conservation of the species. The international nature of sea turtle movement can also open up avenues for cooperation and collaborative research with other countries. |
