View of exposure tank and three species of coral. The coral species represent three different growth morphologies and are covered by fine-grain sediment as part of an experiment conducted by the U.S. Army Engineer Research and Development Center’s Justin Wilkens and Dr. Burton Suedel and the University of Hawaii (UH) at UH’s Kewalo Marine Laboratory February 2021. The white PVC caps were used to measure sedimentation. (U.S. Army Corps of Engineers photo by Justin Wilkens)
