Multibeam bathymetry processed data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS142, Atlantic Ocean

Multibeam data were collected during RV Polarstern cruise PS142 (2024-04-16 to 2024-05-13). Multibeam sonar system was Atlas Hydrographic Hydrosweep DS 3 multibeam echo sounder. Data are processed with Caris HIPS, including sound velocity correction with SV data from CTDs and World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18), tidal correction with TPXO9_atlas_v5 (https://www.tpxo.net/global/tpxo9-atlas), and manual cleaning. The soundings are combined in daily files, the format is XYZ ASCII (<Lon> <Lat> <Depth in meters, positive up, relative to mean sea level>). Additional blockmedian grids have been computed with depth dependent cell size to visualize the data. These grids are not meant for scientific analysis or navigation, but for overview purposes only.

Column water vapour (CWV) measurements in NetCDF format retrieved from GNSS antenna gathered during Polarstern cruise PS147

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.

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 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.

Collection of CTD raw data files of RV POLARSTERN cruises since PS122, September 2019

This data collection contains the CTD raw data files of RV POLARSTERN cruises from 2019-09-20 (starting with PS122) to today. The collection is regularly updated with data from new campaigns. If data was processed and published here on Pangaea, it is linked to the raw data of a respective cruise. Navigate to the respective cruise and see link to "Other version" . Previous CTD raw data was collected in Rohardt (2017) for the time range 2013-06-08 (PS81) to 2019-09-13 (PS121) which can be found here https://doi.org/10.1594/PANGAEA.852715.

Raw data of physical oceanography during RV POLARSTERN cruise PS132

Raw physical oceanography data was acquired by a ship-based Seabird SBE911plus CTD-Rosette system onboard RV POLARSTERN during research cruise PS132. The CTD was equipped with duplicate sensors for temperature (SBE3plus) and conductivity (SBE4). Additional sensors such as an oxygen sensor (SBE43), a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer (FLRTD) and an altimeter (Teledyne Benthos PSA-916) were mounted to the CTD. During this cruise issues with the ECO-AFL fluorometer and the C-Star transmissometer were faced. Cables and sensors were changed several times but the issue remained. Chlorophyll as well as beam transmission values should be treated with extreme care. The data was recorded using pre-cruise calibration coefficients (possibly wrong coefficients for the ECO-AFL fluorometer and the C-Star transmissometer). No correction, post-cruise calibration or quality control was applied. Text files containing bottle-Data were created using SBEDataProcessing steps "Data Conversion" and "Bottle Summary" without applying any correction.

Multibeam bathymetry raw data (Atlas Hydrosweep DS 3 echo sounder entire dataset) of RV POLARSTERN during cruise PS132

Multibeam data were collected with RV Polarstern along the route of cruise PS132 and data acquisition was continuously monitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVPs were retrieved from CTD data. SVPs were processed with HydrOffice SoundSpeedManager (https://www.hydroffice.org/soundspeed/main) and extended with World Ocean Atlas 18 (https://www.ncei.noaa.gov/archive/accession/NCEI-WOA18). SVP data were applied during acquisition. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne/Atlas multibeam processing format (.asd) were recorded with Teledyne/Atlas Parastore software as well as Teledyne Reson format (.s7k) in Teledyne PDS. Raw data files can be processed using software packages like CARIS HIPS/SIPS. For updated vessel configuration files check further details.

Continuous thermosalinograph oceanography along RV POLARSTERN cruise track PS132

Raw data acquired by two SBE21 thermosalinograph and two auxiliary SBE38 temperature sensor (Sea-Bird Scientific, USA) installed in an underway seawater flow-through system on board RV Polarstern were processed to yield a calibrated and validated data set of temperature and salinity along the cruise track. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) at a resolution of 1 sec, and converted to temperature and conductivity using the pre-deployment factory calibration coefficients. The converted data were averaged to 1 min values, outliers were removed, and sensor drift was corrected using coefficients obtained from a post-season calibration performed at Sea-Bird at the end of the measurement season. Salinity was calculated from internal temperature, conductivity and pressure according to the PSS-78 Practical Salinity Scale. Processed data are provided as 1 min means of seawater temperature, conductivity and salinity, aligned with position data taken from the master track. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010). More details are described in the attached processing report.
