Abstract:
This dataset contains the hydrographic profile data collected with the ship based CTD rosette during the cruise PS129 - HAFOS Projekts (Hybrid Antarctic Float Observing System). The CTD is an SBE911plus with 24 bottles, 12 liters each. The CTD/Rosette was equipped with duplicate sensors for temperature (SBE3plus), conductivity (SBE4) and oxygen (SBE43). Additional sensors such as a WET Labs C-Star transmissometer, a WET Labs ECO-AFL fluorometer and an altimeter (PSA-916 Teledyne (Benthos)) were mounted to the CTD. The dataset contains calibrated and quality-controlled parameters as well as uncalibrated parameters, where no quality control was applied. Quality flags are given based on paragraph 6. Quality flags from https://www.seadatanet.org/content/download/596/file/SeaDataNet_QC_procedures_V2_%28May_2010%29.pdf . The CTD bottle data, the cruise report as well as publications using this data are linked below. Additional information on the sensor used for the final data set as well as the water depth is given in a separate info-file.
