VMADCP settings for different periods of cruise 067I033-1. The VMADCP worked properly during the entire cruise, and the data is of good quality. Some exceptions have to be made due to the temporary malfunctioning of the ship’s navigational system, which led to a wrong input of position and heading data between the CTD stations #021/GN017S and #022/GN018A on 27 July 2024. These data were removed from the LTA dataset during processing and must be exckuded from any further additional post-cruise quality control and post-processing (single ping data and STA data). Further exceptions must be made due to severe weather conditions between 12 and 13 August 2024 (track between 60°N and 59°N), which resulted in disturbed data due to a large abun- dance of air bubbles beneath the ship. On 14 August, short-time tests of other sounding de- vices of the vessel were performed resulting in disturbed VMADCP data due to interference between the different systems. These errorneous data have to be removed from the dataset during post-processing.
