“…The authors also observed a positive trend in the partial pressure of CO 2 in water and air during the study period and emphasized the meridional gradient in the direction of air-sea fluxes, in which the northern areas off the coast of Brazil tend to be sources of CO 2 , while the southern regions tend to be sink areas for atmospheric CO 2 . Santos and Garcia (2023) used new data collected by a meteoceanographic buoy belonging to the Brazilian Coastal Monitoring System (SiMCosta) to study coastal currents and salinity variability on the inner shelf of southern Brazil at 32 o S. The authors described a high correlation between currents and the winds, emphasizing the predominance of correlated energy peaks in the period from day 3 to day 10, referring to the passage of atmospheric frontal systems in the study area. They also reported a negative correlation between surface salinity and the discharge of Patos Lagoon, especially during the winter period.…”
