Quality-checked, one-hour resolution cruise track of the Antarctic Circumnavigation Expedition (ACE) undertaken during the austral summer of 2016/2017.

<strong>Dataset abstract</strong> The Antarctic Circumnavigation Expedition (ACE), undertaken in the austral summer of 2016/2017 recorded the cruise track using two independent geo-location instruments: one using GLobal NAvigation Satellite Systems (GLONASS; hereafter referred to as GLONASS) and another primarily using the Global Positioning System (GPS; hereafter referred to as the Trimble GPS). Daily log files were recorded in real-time from both instruments during the expedition and added to MySQL database tables. Following the expedition, quality-checking work has been undertaken to provide a one-second resolution set of positions for the cruise track. Here we present the final quality-checked dataset aggregated to a resolution of one hour. This is of use for understanding the position of the vessel to a lower precision, such as for plotting the track throughout the voyage. <strong>Dataset contents</strong> ace_cruise_track_1hour_YYYY-MM.csv, data file, comma-separated values README.txt, metadata, text file data_file_header.txt, metadata, text file <strong>Dataset license</strong> This quality-checked cruise track dataset is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/
