One-minute average cruise track and ship velocity of the Antarctic Circumnavigation Expedition (ACE) undertaken during the austral summer of 2016/2017.

<strong>Dataset abstract</strong> 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:<br> - the latitude/longitude record of the Quality-checked, one-second cruise track for 21.12.2016 to 11.04.2017.<br> - the latitude/longitude record of the Uncorrected inertial navigation dataset (one-second resolution) for 27.11.2016 to 21.12.2016<br> - the latitude/longitude record of the raw meteorological data (30-second resolution) from 17.11.2016 to 27.11.2016<br> - 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.<br> Basic filtering are applied to remove erroneous observations before the data are averaged to a one-minute resolution. <strong>Dataset contents</strong> cruise-track-1min-legs0-4.csv, data file, comma-separated values data_file_header, metadata, text format README.txt, metadata, text format ace-cruise-track-1min-legs0-4-change-log.txt, metadata, text format <strong>Change log</strong> <strong>v1.1</strong> - Added additional data coverage from 2016-11-17 - 2016-11-22 inclusive.
