Abstract :
We moored a large buoy system in the Southern Ocean (60°S, 140°W) during 2012/01/16 - 2012/12/19. The safely moored buoy system collected valuable data. This time, a logger was developed for operation and assessed. Event analyses use collected data of the tension gauge of the buoy, acceleration information, and a magnetic direction. Furthermore, FFT analysis from a tension gauge and an accelerometer were conducted. Comparison of these with satellite data showed good agreement.
