The paper analyzes nonlinear optimal control of integral–differential equations that describe the optimal management of a forest taking into account intra-species competition and carbon sequestration. The objective function includes the revenues from timber production, operational expenses, and the net benefits from carbon sequestration. A dual system is derived and a necessary extremum conditi...

[1] Successful geologic sequestration of carbon in deep saline aquifers requires accurate predictive models of rock-brine-CO2 interaction. Often overlooked in siliciclastichosted saline reservoirs is the carbonate buffering of the groundwater. Carbonate minerals are ubiquitous, even in siliciclastic host rocks, resulting in some carbonate buffering. Geochemical modeling of rock-brine-CO2 system...

As of 2012, there were an estimated 14,243 ha of seagrass meadows in Tampa Bay. Seagrass meadows are the dominant blue carbon habitat in Tampa Bay, compared to the estimated 6,127 ha of mangroves and 1,779 ha of saltmarsh. However, and unlike mangroves and saltmarshes, the entirety of carbon fixation, growth and decay in seagrass meadows occurs in a submerged environment. While rates of primary...

Mineral carbon dioxide sequestration binds carbon dioxide by reacting it with magnesium silicate minerals to form solid magnesium carbonates that are ready for disposal. Research onmineral sequestration has focused on enhancing process kinetics in aqueous processing schemes. High costs of these processes are associatedwithmineral processing, such as ultrafine grinding, or the consumption of aci...

Will Hawkins discusses carbon sequestration and end-of-life processes in timber structures, the implications for sustainable decision-making structural design.
