Overview
Loggerhead and green turtles were captured by set nets in coastal area. They were transferred to International Coastal Research Center, Atmosphere and Ocean Research Institute, University of Tokyo. When they were released into the sea, devices were attached. The devices were automatically detached from the turtles and were retrieved. Swim speed, acceleration, geomagnetism, depth, temperature and video were obtained. Field study was conducted at the breeding colony of streaked shearwaters. Video camera will be deployed on the berry of birds and movie were obtained during their foraging trips.

Overview of the Observation

Results and Future Plan
During the study period, in total 31 loggerhead and 16 green turtles were captured by set nets. Data loggers were deployed on 1 green turtle and they were retrieved from the green turtle. Behavior and video data were obtained from 38 streaked shearwaters during chick rearing period.
