Cruise Report, RV ATAIR, Cruise 067I033-1, Bremerhaven – Thybor?n – Aberdeen, 23 Jul – 15 Aug 2024 15 Figure 5.2. Distribution of stations carried out during cruise 067I033-1 with density sampling (red dots). 5.5 Near-Realtime Processing of CTD Data All CTD data have been recorded at an original resolution of 24 Hz. Data have been checked and pre-processed during the cruise using the SeaBird SBE Data Processing software, version 7.26.7.129. The preliminary data taken from the downcast of each CTD profile were binned at 1 dbar resolution and sent on a daily basis during the cruise in near-real-time to the Maritime Data Centre at BSH, Hamburg, Germany and there were uploaded to the CrossDataPortal (https://cdp.srx.bsh.de), the open data portal of BSH, from where the data are available to the public. In total, near-realtime data for 92 CTD profiles were submitted and published during the cruise. Pre-processing showed a better performance of the primary temperature/conductivity sensor pack (TC1) for most of the cruise. For station #086/GN053, the first CTD cast had to be can- celled during the upcast due to a search-and-rescue helicopter training manoeuvre of a HM Coast Guard helicopter directly above the vessel. A second CTD cast was later performed to collect the required water samples.
