To determine the scalability of our farm system and algal biomass, we have selected three sites representing three different tropical environments: Florida (seasonally variable), Puerto Rico (low seasonal variability), and Belize (low terrestrial inputs). Working with NOAA’s National Centers for Coastal Ocean Science, we developed site suitability assessments for the Gulf Coast of Florida and the US Caribbean to determine where seaweed farms could be deployed with little or no conflict with other uses.
