Cruise Report, RV ATAIR, Cruise 0671013-1, Bremerhaven - Skagen - Aberdeen, 19 Jul - 11 Aug 2022 
4. Narrative of the Cruise 
The RV ATAIR left its berth at Kohlenkai in Bremerhaven/Germany at 06:00 UTC on 19 July 
2022. It subsequently passed the Bremerhaven Sleuth to begin cruise 067/013-1, the North 
Sea Summer Survey of 2022. The scientific mission began at 10:45 UTC with a test station. 
The continuous logging of underway data for the vessel-mounted Acoustic Doppler Current 
Profiler (VMADCP) was activated at 13:03 UTC after having reached station 
#002/GNO03/ELBE1. Underway measurements for the thermosalinograph (TSG) system were 
activated at 16:10 UTC, after leaving coastal waters enriched with sediment and small-scale 
particles that could obstruct the system’s water flow. Between 19 July 2022 at 19:05 UTC and 
21 July 2022 at 17:00 UTC, respective data could not be obtained due to issues with the elec- 
tronic data transfer and a depleted TSG clock battery. After resolving these issues, the system 
could be activated again. 
The course was set towards the west and initially followed the 54°N latitude. After finishing 
work at station #004/GN007 on 19 July, the boundary between the German and the Dutch 
exclusive economic zones (EEZ) was in reach. Unfortunately, the required permission to con- 
duct scientific research in Dutch waters could not be obtained in time. Instead, the course was 
changed towards the northeast to continue station work at the eastern end of the 55°N section 
at station #005/GN025, which was reached on 20 July. Between 20 July and 22 July, the 55°N 
section was completed without any work being carried out within the Dutch EEZ. 
From 22 July 2022 onwards, the vessel headed south to conduct work at stations 
#016/GN017S to #023/GN014. The latter station (#023/GN014), which was reached on 23 
July, was the southernmost station of cruise 067/013-1. Between 23 and 24 July, the vessel 
transited through the Dutch EEZ on a northeasterly course. Station work and underway meas- 
urements were resumed when reaching the German EEZ near station #024/NEFB on 24 July. 
With two more stations to be completed in German waters, work on the 56°N section was 
resumed in Danish waters at station #027/GN026 on 25 July 2022. The section was completed 
at its western end in UK waters at station #037/GN033A on 27 July. Between 27 and 29 July. 
station work was carried out at stations along the 57°N section in an eastward direction. The 
easternmost station of this section was station #048/GN039. 
Between 29 and 31 July, the vessel crossed the Norwegian Trench several times, thereby 
(eaving or entering the Danish or Norwegian EEZ, depending on the location of the stations. 
The first of eight stations that are part of the Skagerrak station net extension was reached on 
30 July: #052/GN801. After finishing work at station #053/GN802, the vessel headed north to 
station #060/GN808 in Norwegian waters. With a water depth of around 680 m, this was the 
deepest of the Skagerrak stations. After finishing the CTD cast there, a number of large-volume 
samplers (LVS) with capacities of 270 L and 333 L were attached to a steel wire and one after 
the other deployed. They were closed at their respective sampling depths by dropping a fall 
weight that was attached to the wire. Proper closing of the LVS was only partly successful.
