Abstract

This issue of Global Biogeochemical Cycles contains a remarkable set of papers, which critically evaluate a variety of model- and observation-based approaches addressing the oceanic distribution, storage, and transport of CO2. Three of the papers are concerned with observation-based estimates of excess (or anthropogenic) CO2 [Coatanoan et al., this issue; Sabine and Feely, this issue; Chen, this issue]. They focus on the approaches, assumptions, and uncertainties involved in detecting the excess CO2 signal above the ocean's large and variable natural dissolved inorganic carbon (DIC) background.
