Cornish Natalie natalie.cornish@awi.de 2025 Master tracks in different resolutions of POLARSTERN cruise PS145/2, Las Palmas - Walvis Bay, 2024-12-05 - 2024-12-21 dataset Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven https://doi.org/10.1594/PANGAEA.975265 2025-02-12T12:12:41 Raw data acquired by position sensors on board RV Polarstern during expedition PS145/2 was processed to receive a validated master track which can be used as reference of further expedition data. During PS145/2 two Trimble Marine R750 GPS receivers and the iXBlue HYDRINS hydrographic survey inertial navigation system were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.o2a-data.de) with a resolution of 1 sec. 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.
