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

***** 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.
