***** Dataset abstract ***** The ship's cruise track, velocity, course over ground and heading at one-minute resolution for all five legs of the Antarctic Circumnavigation Expedition (ACE) are derived from a combination of: - the latitude/longitude record of the Quality-checked, one-second cruise track for 21.12.2016 to 11.04.2017. - the latitude/longitude record of the Uncorrected inertial navigation dataset (one-second resolution) for 27.11.2016 to 21.12.2016 - the latitude/longitude record of the raw meteorological data (30-second resolution) until 27.11.2016 - where no latitude/longitude record at one-second resolution is available and the ship's velocity was above 2 meters per second, the three-second resolution record of the true and relative wind speed and direction, as well as the heading are used to re-calculate the ship's velocity under the assumption that the course of the ship equalled the heading. Basic filtering are applied to remove erroneous observations before the data are averaged to a one-minute resolution. ***** Dataset contents ***** - cruise-track-1min-legs0-4.csv, data file, comma-separated values - data_file_header, metadata, text format - README.txt, metadata, text format ***** Dataset license ***** This one-minute averaged cruise track and velocity 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/ The Antarctic Circumnavigation Expedition was made possible by funding from the Swiss Polar Institute and Ferring Pharmaceuticals.
