The EUREC4A-OA oceanographic campaign that took place in January-February 2020 in the tropical North-West Atlantic Ocean aboard several research vessels, was a contribution to the broader international research initiative EUREC4A (http://eurec4a.eu/). The cruise was carried out in conjunction with the research vessels L'Atalante (France), Maria S. Merian and Meteor (Germany) and the Ron Brown (USA) as well as with the aircraft and UAV operations and continuous observations from the ground site on the island of Barbados (BCO) and the Saildrone© operations as part of the US ATOMIC project.
This dataset is composed of the uCTD measurements obtained from the R/Vs L'Atalante and Maria S. Merian, processed using a toolbox from GEOMAR-PO based on the article from Ullman and Hebert (JAOT, 2014). A secondary quality check is performed by comparing the uCTD measurements with the nearest CTD stations.
|Utilisation||The Moving Vessel Profiler (MVP) is a profiler measuring temperature, salinity (through conductivity) and pressure. The acquisition was made from the R/Vs L'Atalante and Maria S. Merian during the EUREC4A-OA/ATOMIC experiment from early 2020. The calibration and validation were made by comparing the measurements of near-by CTD stations.|

uCTD are developped by TELEDYNE Oceanscience.
For the R/V L'Atalante two uCTD probes were deployed: S/N 70200293 and 70200333
