Ziel der Reise / Objectives of Cruise:
Physical oceanographic measurements conducted during cruise M164 (GPF-19-1-105) were funded by the German Ministry for Education and Research (BMBF) through the RACE-Synthesis effort, work package 1.2. Focus was on collecting physical-oceanographic data along the geographic latitude of ~47?/48?N as well as along a survey line located on the western flank of the Mid-Atlantic Ridge. Scientific tools comprised vertical profiling of the entire water column using two lowered Acoustic Doppler Current Profilers (LADCP) and a Conductivity-Temperature-Depth-Oxygen (CTDO) unit, all attached to a carousel water sampler. Water sampling activities consisted of taking oxygen and salinity samples for the sake of conductivity-/oxygen-sensor calibration as well as taking samples for the analysis of anthropogenic trace gases (chlorofluorocarbon-12, CFC-12; sulphurhexafluoride, SF6). Hydrographic work on 126 stations was complemented by the recovery and redeployment of deep-sea moorings located at the eastern and western continental margins of the North Atlantic (Goban Spur at the Irish shelf break; eastern flank of Flemish Cap; Flemish Pass). Eight locations with inverted echo-sounders carrying pressure sensors (PIES) installed along 47?/48?N were visited. Respective station work was related to data retrieval via acoustic telemetry and subsequent instrument recovery. The deep-sea moorings and the PIES formed the oceanic long-term observatory NOAC ("North Atlantic Changes"), which was deinstalled by the end of the cruise. Only two moorings located at Goban Spur have remained in the water at the end of the cruise. In total, 15 Argo floats (seven with a profiling depth of 2000m and eight with a profiling depth of 4000 m) were deployed along 47?/48?N.
