The Living Seas at EPCOT Center is a 5.7 million gallon sea water aquarium constructed from reinforced concrete. The design of a sacrificial magnesium cathodic protection system to remediate corrosion of the Main Tank wall and Aeration Tower has required an understanding of its impact on the marine life, sea water chemistry and other structures in the aquarium. This has been achieved by an ongoing research project and the application of a recently developed method (Reinforcement Inspection System for Concrete) that can measure the magnitude and direction of current flow at submerged concrete surfaces.
