On behalf of Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung we post-processed navigation data from former campaigns of the research vessels Polarstern and Heincke. The job was about data validation, filtering, interpolation, generalization and documentation of all applied processes. The objective was to achieve a valid “master track” for each campaign which will be used for georeferencing scientific data and for visualization in data portals. All mastertracks are now available in the longterm data archive PANGAEA.de (Heincke mastertracks, Polarstern mastertracks in column master track).
