This dataset contains ice motion observations made under the Australian Antarctic Program, projects 4593 and 4506. Data was obtained using two open-source ice motion loggers, hereafter ice buoys. Two ice buoys were deployed on landfast ice just north of the Swain Group, Antarctica (66.2 degr. S, 110.6 degr. E), on 13 October 2020. Instruments were retrieved on 10 November 2020. The ice buoys measure motion in 9-degrees-of-freedom at 10Hz using a VectorNAV VN-100 IMU, with an accuracy of O(mm) for short waves and O(cm) for long waves. Both instruments also record their geographical location through GPS. Full time series of their motion is processed on board and summaries are send through Iridium. Wave spectra and GPS coordinates were transmitted roughly every 4 hours. The dataset comprises the raw data measured by the two ice buoys, we have referred to them as AAD_17 and AAD_18 for administrative reasons. Data output for each buoy is: A = vertical acceleration (mean subtracted) (m/s^2); P = pitch (degrees); R = roll motion (degrees); z = surface elevation (m); t = UTC time (Matlab ‘datenum’ format, i.e., days since year 0000); lat = latitude; lon = longitude. The geographical coordinates ‘lat’ and ‘lon’ are in degrees.
