Optimized observation cycle for the tidal harmonic analysis
The Japan Coast Guard observes the tidal time series using the Autonomous Ocean Vehicle （AOV） to precisely determine datum levels. As the AOVs utilize solar energy for their observation equipment, interruptions of observation caused by the power shortage due to decrease in the amount of sunshine in the winter becomes an operational issue. In this paper, we investigate whether short observations during interruptions or prolonged observation are effective to obtain reliable tidal harmonic constants. We found that short observations of more than 24 hours during interruptions or observations from the next year on the same date as the interruption make the tidal harmonic constants close to the value calculated from no missing data. The results of this study can be used as index for deciding the implementation of observation in winter or making plans for observation using AOVs.
