Located off the coast of Delaware and composed of disposed subway cars, marine vessels, and military vehicles, Redbird Reef serves as one of the most unique underwater laboratories in the U.S. Since 1996, a wide variety of methods including geoacoustics, ROVs and AUVs, and cameras have allowed scientists to track how this artificial reef has evolved. This study combines almost two decades of data to understand the degradation of reef structures, shifts in the surrounding seabed, and how marine organisms are using the reef. Outcomes help answer pertinent questions: How long do artificial reefs last? When do they transition to becoming marine debris? How can our knowledge about artificial reefs be applied to building other nearshore underwater structures like wind farms? New data visualization tools such as maps and 3D models are being developed to share these results with the public and coastal planners.
