| Outline of Final Research Achievements |
This study developed the estimation method of geographical location of marine organisms by using the geomagnetic and gravity sensors equipped with animal-borne data loggers. We developed micro data logger that can record geomagnetic and gravity data for longer period. Through the several experiments on the nesting loggerhead turtles, we figured out the needs of strict corrections of geomagnetic sensor, and also of data correction of geomagnetic sensor drifted by water temperature to achieve the estimation of geographical location of loggerhead turtles with sufficient accuracy.
