CTD data from FAROFA surveys, 2017-09-05 to 2019-04-22
This dataset contains hydrographical profiles achieved around Fernando de Noronha Archipelago off northeast Brazil within the framework of Fish around Fernando de Noronha FAROFA surveys performed in sept 2017 (9 profiles), April 2018 (17 profiles) and April 2019 (12 profiles). CTD profiles were achieved using a RBR Concerto logger measuring depth, temperature, salinity and fluorescence. Deployment were made using a fishing rod and 1 kg ballast installed under the logger.
