SPNA transport 2020 The scientific program of the MARIA S. MERIAN MSM94 expedition was dedicated to studies on the intensity of water mass transformation and the transport of water masses in the boundary current systems off Labrador and at the southwestern tip of Greenland. During the expedition we redeployed 11 moorings and recovered 1 bottom lander. Measurements of the vertical structure of temperature, salinity, density, oxygen, optical properties and the flow along selected sections have been surveyed during the MSM94 expedition. Close to the surface, permanent registrations are carried out with the thermosalinograph (temperature, salinity) and meteorological data are continuously collected. Flow measurements up to 1000m depth are performed with the ships installed ADCPs. Argo floats (IFREMER, BSH) and surface drifter (NOC, UK) were also deployed. The expedition is a contribution to international projects (OSNAP, Blue Action, EuroSea). The expedition was conducted during the COVID-19 pandemic and modifications to the science program had to be applied (e.g. Start/end-port Emden, Germany, reduced science crew and respective cut’s in data acquisition).
