Schütte, Florian (2026): Master track of ALKOR cruise AL661 in 1 sec resolution (zipped, 12 MB) [dataset]. GEOMAR - Helmholtz Centre for Ocean Research Kiel, PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.998081 (DOI registration in progress)

Raw data acquired by position sensors on board RV Alkor during expedition AL661 were processed to receive a validated master track which can be used as reference of further expedition data. During AL661 data from the Seapath 330 system, the Furuno GP-170 receiver and the SAAB R6 system were used to calculate the mastertrack. Data were downloaded from Insightics Marine DSHIP Extraction (https://dship.o2a-data.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.
