Description
Reefense seeks to develop self-healing, hybrid biological and engineered reef-mimicking structures to mitigate the coastal flooding, erosion and storm damage that increasingly threaten civilian and DoD infrastructure and personnel. Under Reefense, custom wave-attenuating base structures will promote calcareous reef organism (coral or oyster) settlement and growth, which will enable the system to self-heal and keep pace with sea level rise over time. A system will be put in place that will also attract non-reef building organisms necessary to help maintain a healthy, growing system. Finally, adaptive biology (other than genetically modified organisms) will enable improved coral and oyster resilience against disease and temperature stress, to ensure compatibility with a changing environment.
