Dates: 5 February – 10 March 2023
Vessel: RV Endeavour
Lead scientist: Ben Moat (NOC, PI of RAPID project), Louis Clement
Work area: Western boundary of the subtropical North Atlantic at the RAPID moorings at 26°N
Key objectives: Deployment of two Sonardyne AZA drift-correcting pressure sensors (as part of a wider RAPID expedition)
EPOC partners involved: WP5
The two pressure sensors will be used to evaluate whether the barotropic large-scale transport variability can be directly measured. At present, this contribution to the measured AMOC transport is inferred using various assumptions at the different measurement arrays.
Data will be recovered in a future expedition and evaluated alongside existing tall moorings from the RAPID 26°N project and satellite altimetry data.
