The Brazilian Ocean Acidification Network (BrOA) was established in December 2012 during the Workshop "Studying Ocean Acidification and its effects on marine ecosystems", organized by the IGBP, USP, CNPq, and INPE. Briefly, the group aims to integrate the Brazilian researchers in a wide interdisciplinary national network on Ocean Acidification (OA) studies and to contribute with the international programs in course (LAOCA, GOA-ON, SOLAS, CLIVAR-CLIC). The group acts on distinct environments along the Brazilian coast from estuaries to open ocean regime. Recently, BrOA published in the journal Environmental Management a review entitled "The Western South Atlantic Ocean in a High CO2-World: current measurements capabilities and perspectives"
