Start-Finish: St John’s, Newfoundland – St John’s, Newfoundland
Vessel: RV L’Atalante
Lead scientist: Damien Desbruyeres, IFREMER
Work area: Flemish Cap, Grand Banks (NW Atlantic)
Key objectives: Better understanding of the physics that disconnect subarctic and subtropical AMOC variability, in particular i) the interactions between Deep Western Boundary Current (DWBC) and seafloor topography, and ii) interactions between the DWBC – and the North Atlantic Current (NAC). The expedition will recover 9 tall mooring lines deployed for EPOC by MSM121 in 2023 as well as the micro-ryo and 3 EPOC Bottom Pressure Recorders. The team will carry out CTD-LADCP sections (42 stations) and VMP (25 profiles) and take 9+ sediment cores, plus RAFOS deployments (16), Deep-Argo Deployment and high-resolution tow-yos (3 or more). This cruise is part of IFREMER’s CROSSROAD project
EPOC partners involved: IFREMER, others
