Time-series of the array positions and sea-surface tracks for campaigns at G20. a Time-series of the array positions. Open black circles, blue x-marks, red crosses, open green squares show the solutions estimated using Method-1, Method-2, Method-3, and Method-4, respectively. b Sea-surface platform positions when the acoustic signals were transmitted. The colors show NTDs subtracting the long-term fluctuation of NTDs estimated by Model-3
