Dataset identification

Title of datasetCTD DATA - EUREC4A_OA Atalante Cruise
Narrative summary of datasetThe EUREC4A-OA oceanographic campaign that took place in January-February 2020 in the tropical North-West Atlantic Ocean aboard the research vessel L'Atalante was a contribution to the broader international research initiative EUREC4A ( The cruise was carried out in conjunction with the research vessels 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. The overall objective of the EUREC4A-OA campaign was to collect observational data that will enable research on dynamic and thermodynamic processes in the atmosphere and the ocean, in order to better understand the role of fine ocean scales both in the internal dynamics of the ocean and in air-sea interactions.  To this end, measurements of oceanic and atmospheric profiles have been carried out to observe the temporal evolution and spatial heterogeneity of the atmospheric and oceanic boundary layers and the properties in these two fluids beyond these layers. Autonomous observation platforms (submarine glider, Argo profiling floats, surface buoys and the OCARINA and PICCOLO prototypes) complemented the observations carried out on board ships. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.
Summary of processing methodologyThe frame is equipped with a SBE911+ CTD, 2 LADCP, electronic reversing sensors and other sensors.The CTD was controlled from the LOPS computer container. The same Seabird 911+ CTD probe (s/n. 813) was used throughout the cruise. It was equipped with two sets of T, C, and O2 sensors. On the CTD frame were also mounted, 2 LADCP (RDI 300 kHz), 4 SIS reversing sensors (Pressure and Temperature), a Wet labs transmissometer, a Chelsea fluorometer, a Par & Spar and an IXSEA pinger. The CTD sensors used are as follows: Primary sensors Secondary sensors Temperature (SBE3+) s/n 2911 s/n 4594 Conductivity (SBE4c) s/n 3194 s/n 3166 Oxygen (SBE43) s/n 1402 s/n 526
