Ziel der Reise / Objectives of Cruise:

The scientific program of the RV MARIA S. MERIAN MSM129/1 expedition (expocode M6m²20240525 ) was dedicated to improvements in data acquisition and data/metadata management aspects of the DAM "Underway Research Data" project. A case study conducted during MSM129/1 addressed the establishment of a workflow in the DAM underway data workflow to favour situation-dependent sampling. Obviously, this needs to be done without additional steaming time. The test case chosen for MSM129/1 was the mapping of "potential seamounts", but other conceivable cases would be the sampling of mesoscale ocean structures. Upper ocean surveys were done with a profiling underway system (Moving Vessel Profiler, MVP) and for the purpose to estimate how deep the North Atlantic marine heat wave (established in 2023) is traceable. Four CTD's were acquired to calibrate mooring instruments (MSM129/leg 2) but also to estimate for the Orphan Knoll region if west/east differences in the T/S properties at the Deep Western Boundary Current core depth (approx. 2900m; referenced to the 53?N observatory) can be identified. Embedded in the DAM project thermosalinograph (TSG), Fluorometer, Acoustic Doppler Current Profiler (ADCP), FerryBox, and Bathymetry data were acquired. The expedition was a contribution to national (DAM Underway Research Data) and international projects (EU projects EuroGO-SHIP and ObsSea4Clim).
