Ocean Acidification

Richard Matear is a biogeochemical modeller with CMAR's Climate Adaptation Flagship, with a special interest in understanding the role that the marine carbon cycle plays in controlling atmospheric carbon dioxide (CO2) concentrations, particularly in the Southern Ocean. Present estimates indicate the oceans are removing about 30 per cent of the anthropogenic CO2 emissions, approximately 40% of which occurs in the Southern Ocean. The oceans are expected to continue to absorb large quantities of anthropogenic carbon dioxide, but the extent to which the ocean uptake will be effected by climate change are uncertain. Current research involves the development and implementation of a hierarchy of ocean biogeochemical (BGC) models to model carbon cycling in the ocean, predict oceanic uptake of anthropogenic CO2 and the air-sea exchanges of 12CO2, 13CO2 and O2 into atmospheric transport models. Work by a joint observational and modeling team is aimed at critically comparing the models with observations to assess the BGC model performance. The development and application of BGC models is occurring on the one-dimensional, regional and global scales.
