Krastel, Sebastian (2025): Master track of ALKOR cruise AL637 in 1 sec resolution (zipped, 26 MB) [dataset]. Institute of Geosciences, Christian-Albrechts University Kiel, PANGAEA, https://doi.org/10.1594/PANGAEA.988095

Raw data acquired by position sensors on board RV Alkor during expedition AL637 were processed to receive a validated master track which can be used as reference of further expedition data. During AL637 data from the Seapath 330 system, the Furuno GP-170 and the Furuno GP-150 GPS receivers were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (https://dship.bsh.de) with a resolution of 1 sec. Processing and evaluation of the data is outlined in the data processing report. Processed data are provided as a master track with 1 sec resolution derived from the position sensors' data selected by priority and a generalized track with a reduced set of the most significant positions of the master track.
