The Brazilian Ocean Acidification Research Group (BrOA; www.broa.furg.br) was created in December 2012, as an action of the activities of the workshop "Studying Ocean Acidification and its Effects on Marine Ecosystems" (Dec. 4-6, 2012, Cananéia, Brazil). BrOA operates in distinct environments along the Brazilian coast, including coastal and estuarine ecosystems and oceanic open waters.

The International Surface Ocean - Lower Atmosphere Study (SOLAS) project is an international research initiative aiming to understand the key biogeochemical-physical interactions and feedbacks between the ocean and atmosphere. For more than ten years, SOLAS has been fostering cutting-edge research in air-sea interactions, as well as promoting communication and integration of different research groups all over the world.

The focus of this joint workshop is to bring together the the international community that conducts research on sea-air CO₂ fluxes and their implication to ocean biogeochemistry (e.g. ocean acidification, changes in ocean biogeochemistry), as well as on the response of marine organisms to ocean acidification effects (bio-assays), paleoceanography and proxies of past ocean acidification events and carbonate system, and marine ecosystem modeling.

We encourage participation from BrOA and SOLAS researchers. The workshop will combine invited and selected talks, along with breakout group discussions corresponding to the main BrOA network and SOLAS topics. The general content of presentations, along with summations of general and breakout group discussions will be included in the Third BrOA Report/SOLAS Workshop Report. Here, participants will assess the advances in analytical methods and reporting scientific data on sea-air gas fluxes and ocean biogeochemistry, and the regional needs to study ocean acidification and sea-air gas fluxes, such as analytical and logistic facilities, data access, or capacity building. Activities of emerging research groups (e.g. Latin America, Asia, Africa) will also be reported. In addition it is anticipated that a journal manuscript assessing the state of the art of ocean acidification studies in South America will be prepared.
