The CTD raw data aredelivered from Dr. Sandra Tippenhauer (AWI). The station book of the RV Heincke cruise is extractedfrom the DAVIS SHIP data base (https://dship.awi.de). The first CTD station and cast is processedmanually in SBE Data Processing to configure the *.psa Seabird routines Data Conversion, WildEdit, Bottle Summary, Split, Translate, Cell Thermal Mass, Loop Edit and Bin Average. The Seabirdroutines are then run in a batch job CTDjob in ManageCTD to process the complete CTD dataset. The downcast of each CTD station/cast is used for further processing. In CTDjob the startrecord and the lowest altimeter point of the downcast is selected. With the Utilities → Dship Ebookfunction of ManageCTD the DAVIS SHIP station book extraction is used for getting the headerinformation of all CTD stations/casts of the cruise. ManageCTD Utilities → Find Profile functioncompares station times of the header with the entries in the station book to find out the correctnaming of the stations and casts. In CTDheader in ManageCTD the header information of each CTDstation/cast is displayed, controlled and corrected if necessary. CTDdespike in ManageCTD is usedfor a visual check of the data and to erase/interpolate spikes in the data if necessary. Additionally, asensor pair (Temp1/Sal1 or Temp2/Sal2) is chosen for each station/cast of the RV Heincke cruise inCTDdespike.ManageCTD Utilities → CheckDoubleSensors controls the quality of temperature and conductivitysensors. For this purpose outliers of too high sensor pair differences could be removed. The data isthen converted to spreadsheet format with dsp2odv for visualization of the data in Ocean Data View(ODV). The second visual inspection of the CTD data allows a comparison with data from other CTDcasts from close-by stations to verify the oxygen sensor data. Therefore, potential reference cruisedata is downloaded from PANGAEA (http://www.PANGAEA.de). The reference data is convertedto *.mat format. In the ManageCTD Final Processing the CTD data is displayed together with thereference data. Bad data points, sensors or casts are interpolated or erased from the data set andfilters are applied if necessary. The processed CTD data are written to text files and imported toPANGAEA (http://www.PANGAEA.de) for publication.Page 1 of 8Figure 1: CTD data Processing WorkflowPage 2 of 83 Expedition detailsVessel name RV HeinckeExpedition number HE596Expedition leader Brenner, MatthiasExpedition start 08.04.2022 BremerhavenExpedition end 13.04.2022 BremerhavenDuration 5 daysNo. of CTD casts 17BSH ID 20220156Expedition report https://doi.pangaea.de/10.48433/cr_he596Expedition map https://download.pangaea.de/reference/113265/attachments/HE596_nav.jpgEvent list https://www.pangaea.de/expeditions/events/HE5964 Sensor LayoutThis chapter describes the CTD sensors mounted during this cruise:SBE 911plus CTD (SN: 1015), SBE Instrument Configuration Version 7.23.0.1.ID Sensor Name Serial No. Calibration Date55 TemperatureSensor 4918 05-Mar-213 ConductivitySensor 3810 09-Feb-2145 PressureSensor 1015 26-Jan-1755 TemperatureSensor 5110 05-Mar-213 ConductivitySensor 3827 02-Feb-120 AltimeterSensor Valeport None71 WET_LabsCStar 435 None20 FluoroWetlabECO_AFL_FL_Sensor 1365 7.1.20225 ProcessingDetails of processing procedures and processing parameters are described in CTD Processing Log-book of RV Heincke (hdl:10013/epic.47427).Density Inversions and Manual ValidationObvious outliers were removed manually.

The CTD raw data aredelivered from Dr. Sandra Tippenhauer (AWI). The station book of the RV Heincke cruise is extractedfrom the DAVIS SHIP data base (https://dship.awi.de). The first CTD station and cast is processedmanually in SBE Data Processing to configure the *.psa Seabird routines Data Conversion, WildEdit, Bottle Summary, Split, Translate, Cell Thermal Mass, Loop Edit and Bin Average. The Seabirdroutines are then run in a batch job CTDjob in ManageCTD to process the complete CTD dataset. The downcast of each CTD station/cast is used for further processing. In CTDjob the startrecord and the lowest altimeter point of the downcast is selected. With the Utilities → Dship Ebookfunction of ManageCTD the DAVIS SHIP station book extraction is used for getting the headerinformation of all CTD stations/casts of the cruise. ManageCTD Utilities → Find Profile functioncompares station times of the header with the entries in the station book to find out the correctnaming of the stations and casts. In CTDheader in ManageCTD the header information of each CTDstation/cast is displayed, controlled and corrected if necessary. CTDdespike in ManageCTD is usedfor a visual check of the data and to erase/interpolate spikes in the data if necessary. Additionally, asensor pair (Temp1/Sal1 or Temp2/Sal2) is chosen for each station/cast of the RV Heincke cruise inCTDdespike.ManageCTD Utilities → CheckDoubleSensors controls the quality of temperature and conductivitysensors. For this purpose outliers of too high sensor pair differences could be removed. The data isthen converted to spreadsheet format with dsp2odv for visualization of the data in Ocean Data View(ODV). The second visual inspection of the CTD data allows a comparison with data from other CTDcasts from close-by stations to verify the oxygen sensor data. Therefore, potential reference cruisedata is downloaded from PANGAEA (http://www.PANGAEA.de). The reference data is convertedto *.mat format. In the ManageCTD Final Processing the CTD data is displayed together with thereference data.
