Winter, Christian (2025): Master track of ALKOR cruise AL612 in 1 sec resolution (zipped, 38 MB) [dataset]. Christian-Albrechts-Universität zu Kiel, PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.987901 (DOI registration in progress)

Raw data acquired by position sensors on board RV Alkor during expedition AL612 were processed to receive a validated master track which can be used as reference of further expedition data. During AL612 data from the motion reference unit Kongsberg MRU-Z, the Trimble MPS865 GPS receiver, the Furuno GP-170 and Furuno GP-150 GPS receivers and from the NAVIGAT X MK 1 gyro compass were used to calculate the mastertrack. Data were downloaded from DAVIS SHIP data base (http://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.
