Raw data acquired by position sensors on board RV Alkor during expedition AL644 were processed to receive a validated master track which can be used as reference of further expedition data. During AL644 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.
The ship campaign PS147 (Atlantic Transit) with the German research vessel Polarstern took place from 12 March to 14 April 2025. The transit proceeded from Stanley, Falkland Islands, to Bremerhaven, Germany, with a stopover in Mindelo, Cape Verde, dividing the campaign into two sections, PS147/1 and PS147/2. During the voyage, several climate zones were crossed, including the Intertropical Convergence Zone (ITCZ). Here, we present the column water vapour retrieved from GNSS data. These data form part of a series of standardized datasets of atmospheric observations collected during the PS147 campaign.
Raw data acquired by position sensors on board RV Elisabeth Mann Borgese during expedition EMB380 were processed to receive a validated master track which can be used as reference of further expedition data. During EMB380 data from the motion reference unit exail Phins Gen.3, the Trimble SPS356 GPS receiver, the Furuno GP-170 and the Furuno GP-150 GPS receiver 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.
Raw data acquired by position sensors on board RV Heincke during expedition HE673/1 were processed to receive a validated master track which can be used as reference of further expedition data. During HE673/1 the inertial navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV were used as navigation sensors. Data were downloaded from DAVIS SHIP data base (https://dship.awi.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.

During the voyage, several climate zones were crossed, including the Intertropical Convergence Zone (ITCZ). Here, we present data from the ship-integrated instruments within the DavisShip system (DShip), including meteorological parameters from the weather station as well as ship position and orientation from the navigation system. These data form part of a series of standardized datasets of atmospheric observations collected during the PS147 campaign.
Raw data acquired by position sensors on board RV Heincke during expedition HE672 were processed to receive a validated master track which can be used as reference of further expedition data. During HE672 the inertial navigation system IXSEA PHINS III and the GPS receivers Trimble Marine SPS461 and SAAB R5 SUPREME NAV were used as navigation sensors.

Ocean velocities were collected by a Teledyne RDI 600 kHz Workhorse Mariner ADCP that was mounted on RV HEINCKE during RV HEINCKE cruise HE667. The transducer was located at 4 m below the water line. The instrument was operated in single-ping, broadband mode with bin size of 1 m and a blanking distance of 1 m. The velocity of the ship was calculated from position fixes obtained by the Global Positioning System (GPS) received directly from RV HEINCKE. Heading, Pitch and Roll were obtained both from the MRU of RV HEINCKE and the internal ADCP gyro. Heading as well as pitch and roll data from ADCP's internal gyrocompass and the navigation and motion data were used by the data acquisition software ViSea DAS (AquaVision®) internally to convert ADCP velocities into earth coordinates. Accuracy of the ADCP velocities mainly depends on the quality of the position fixes and internal ADCP heading data. Further errors stem from a misalignment of the transducer with RV HEINCKE's centerline. ADCP data is provided at minutely sample rate. Raw data or secondly binned data are available on request.
