Abstract
Abstract
The quantitative assessment of the carbonate system represents one of the biggest challenges toward the "Sustainable Development Goals" defined by the United Nations in 2015. In this sense, the present study investigated the Spatio-temporal dynamics of the carbonate system and the effects of the phenoms ENOS and ENSO over the Cabo Frio upwelling area. The physical characterization of the site was carried out through data on wind speed and sea surface temperature (SST). Water samples were also collected during the oceanographic cruise onboard the Diadorim Oceanographic Research Vessel. From these samples, the parameters of absolute and practical salinity, density, pH, total alkalinity, carbonate, calcite, aragonite, \(C{O}_{3}^{2-}\), \(HC{O}_{3}^{-}\), dissolved inorganic carbon, carbon dioxide, partial pressure of carbon, calcium, and total boron were obtained. After the physical-chemical survey described above, the same parameters were calculated through thermodynamic modeling with the Marine Chemical Analysis (AQM) software loaded with temperature, salinity, TA, and pH parameters. This manuscript presents original data on the carbonate system and the "acidification" process influenced by the Cabo Frio upwelling, which directly depends on the El Niño and La Niña phenomena oscillations in the sea surface temperature (SST).
