One method for minimizing climate change is to capture CO2 from power plants and inject it into the deep ocean, thus reducing the magnitude and rate of change of CO2 concentration in the atmosphere and the surface ocean. Many discharge options are possible, with varied mixing and retention characteristics. The ocean's capacity is vast, and mathematical models suggest that injected CO2 could remain sequestered for several hundred years. While theoretical and laboratory studies support the viability of ocean storage, field experiments are necessary to realistically evaluate the environmental impact.
