                         ABSTRACT: Using a micrometeorololical tower, direct measurements 
                         of sensible (H) and latent (Le) heat fluxes were performed onboard 
                         the Brazilian Navy Research Ship Vital de Oliveira, during the 
                         period between 14 November and 6 December 2017, along her route on 
                         the 38 oW meridian during the 17th cruise of the PIRATA Brazil 
                         (Prediction and Research Moored Array in the Tropical Atlantic) 
                         project. Using conventional meteorological and oceanographic data, 
                         the heat fluxes were also estimated from bulk parameterizations. 
                         The present study describes for the first time the direct 
                         measurements and the estimates, as well as the differences between 
                         H and Le taken from the Eddy Covariance method (EC) and by the 
                         bulk parameterizations. Both the EC and bulk time series presented 
                         a very similar variability, especially for the Le magnitude. The 
                         bulk method, in general, sub estimated H in respect to the EC 
                         method. The mean sensible heat flux was 12 W/mē for the EC method 
                         whereas it was 5 W/mē for bulk, and there were a dependency of the 
                         series with the difference between the sea surface temperature and 
                         the air temperature. For Le, the magnitudes presented by both 
                         methods differed, with the bulk method, in the temporal mean of 
                         the time series, super estimating substantially Le in respect to 
                         the EC (117 W/mē for the bulk estimate and 48 W/mē for EC). For 
                         both heat fluxes but especially for Le, the major differences 
                         between the tow methods occurred on strong wind conditions.",
