[1] We present ocean chemistry calculations based on ocean general circulation model simulations of atmospheric CO 2 emission, stabilization of atmospheric CO 2 content, and stabilization of atmospheric CO 2 achieved in total or in part by injection of CO 2 to the deep ocean interior. Our goal is to provide first-order results from various CO 2 pathways,(More)
The prevention of deforestation and promotion of afforestation have often been cited as strategies to slow global warming. Deforestation releases CO(2) to the atmosphere, which exerts a warming influence on Earth's climate. However, biophysical effects of deforestation, which include changes in land surface albedo, evapotranspiration, and cloud cover also(More)
A coupled climate and carbon (CO 2) cycle model is used to investigate the global climate and carbon cycle changes out to the year 2300 that would occur if CO 2 emissions from all the currently estimated fossil fuel resources were released to the atmosphere. By the year 2300, the global climate warms by about 8 K and atmospheric CO 2 reaches 1423 ppmv. The(More)
[1] We simulate direct injection of CO 2 and uptake of CFC-11 in a global, three-dimensional ocean general circulation model using two model resolutions: a coarse resolution of 4° in longitude by 2° in latitude and a finer resolution of 1° in both longitude and latitude. We assess the impact of resolution on the relative effectiveness of ocean carbon(More)
Direct injection of CO 2 into the ocean is a potentially effective carbon sequestration strategy. Therefore, we want to understand the effectiveness of oceanic injection and develop the appropriate analytic framework to allow us to compare the effectiveness of this strategy with other carbon management options. Here, after a brief review of direct oceanic(More)
In the present work, the two-equation k-L model [G. Dimonte and R. Tipton, Phys. Fluids 18, 085101 (2006)] is extended by the addition of a third equation for the mass-flux velocity. A set of model constants is derived to satisfy an ansatz of self-similarity in the low Atwood number limit. The model is then applied to the simulation of canonical(More)
