Resumo
The carbon biogeochemical cycle in nature involves the atmosphere, ocean, terrestrial and marine
biota, and mineral reservoirs, with major fluxes between the atmosphere and both terrestrial biota and
ocean waters. Studies link the increase of CO2 and CH4 (GHG) to climate change and anthropogenic
activities. Coastal zones have a significant impact on the carbon cycle. This study examines GHG
concentrations in estuary systems close to port zones, focusing on Santos and São Sebastião ports in
São Paulo, Brazil. Santos Port, the largest in Latin America, and São Sebastião Port, with a petroleum
terminal, can be significant contributors of GEE. A preliminary campaign measured CO2 and CH4 for 27
hours using a portable GHG analyzer on the research vessel Albacora from the University of São Paulo's
Oceanographic Institute. Results showed promising GHG concentrations, with CO2 levels above 420
ppm near Santos and above 450 ppm near São Sebastião, for methane, the major concentration was
~3 ppm, but in short period of acquisitions, in the major part of traject the level was between ~1.8 - ~1.9
ppm.
