Abstract
The atmospheric concentration of CO2 and other greenhouse gases are increasing and changing the radiative properties of the atmosphere. To study the response of the ocean-climate system to this climate perturbation, investigators have integrated ocean-climate models with an atmospheric CO2 concentration that rises over time to double, triple or quadruple the control CO2 level [Bi et al., 2001; Hirst, 1999; Manabe and Stouffer, 1993; Goosse and Renssen, 2001]. The oceanic response in these experiments typically includes widespread surface warming, retreat of sea ice and a general increase in upper ocean stratification, all of which may impact upon the ocean biogeochemistry. The substantial reductions in formation rate and/or density of intermediate and deep water masses that occur in these simulations would likely affect biogeochemical cycling in the ocean and the air-sea exchange of oxygen and CO2. This chapter uses a biogeochemical model to examine the effect of global warming on biogeochemical cycling in the ocean focusing on the oceanic oxygen distribution. The chapter discusses the simulated oxygen changes in the ocean and demonstrates the potential of using oxygen changes to track global warming and provide observations to assess climate model simulations.
