Brix-Elsig, Saskia (2026): Master track of MARIA S. MERIAN cruise MSM145 in 1 sec resolution (zipped, 70 MB) [dataset]. Senckenberg am Meer, Wilhelmshaven, PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.997220 (DOI registration in progress)

Raw data acquired by position sensors on board RV MERIAN during expedition MSM145 were processed to receive a validated master track which can be used as reference of further expedition data. During MSM145 the motion reference unit Kongsberg SeaTex AS MRU-5 combined with Kongsberg SeaTex AS Seapath 320 and the GPS receivers Trimble SPS855 and SAAB R4 were used as navigation sensors. 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.
