Abstract:
Offshore macroalgal farming is being assessed for its potential as a biofuel resource. Yet, scalability and siting are still under evaluation. We have developed a framework to site and estimate offshore macroalgal harvest potential by simulating farm growth from oceanographic inputs coupled to a dynamic macroalgal growth model. Potential farm locations are also constrained by operational requirements and existing use of ocean spaces. We will demonstrate the utility of this framework for giant kelp, Macrocystis pyrifera, along the California coast and evaluate industry scaling required for consideration as a biofuel resource.
