Gabriel, Corey J.; Robock, Alan; Xia, Lili; Zambri, Brian (2016): The G4Foam Experiment. Global Climate Impacts of Regional Ocean Albedo Modification. In Atmos. Chem. Phys. Discuss., pp. 1–30. DOI 10.5194/acp-2016-849.

"Here we present the results of climate model simulations of a unique Geoengineering Model Intercomparison Project Testbed experiment to investigate the benefits and risks of a scheme that would brighten certain oceanic regions. The National Center for Atmospheric Research CESM-CAM4-CHEM global climate model was modified to simulate a scheme in which the albedo of the ocean surface is raised over the subtropical ocean gyres in the Southern Hemisphere. Like the commonly studied stratospheric geoengineering and marine cloud brightening proposals, this ocean albedo modification scheme is not currently possible. However, a stable, nondispersive foam, comprised of tiny, highly reflective microbubbles has been developed under idealized conditions, and, hence, a geoengineering scheme which simulates the effects of large-scale deployment of these microbubbles is appropriate to study at this time."
