This dataset contains the validated master track of the S/Y Eugen Seibold during expedition ES19C12, with a time resolution of about 10 seconds. This master track can be used as reference for further expedition data. For creating the master track, the 1-second resolution raw data acquired by the GPS position sensor on board S/Y Eugen Seibold were processed, averaging latitude and longitude within equidistant 10-second intervals. Quality control was performed visually and by checking the maximum speed calculated between neighbouring positions. In case of unrealistically high speeds, data points have been removed.

Details about the processing routine and the meaning of the quality flag are given in the Standard Operating Procedure (SOP). Cruise-specific remarks are given in the Data Processing Report (DPR).
