Elkhorn corals (Acropora palmata) on the seafloor along the northeastern coast of Buck Island, U.S. Virgin Islands, have died and collapsed into rubble. As coral reef structure degrades, habitat for marine life is lost and nearby coastlines become more susceptible to storms, waves, and erosion.

Healthy elkhorn coral (Acropora palmata) on the seafloor along the southeastern coast of Buck Island, U.S. Virgin Islands. Elkhorn coral is one of many important reef-building species that create 3D structure on the seafloor. Coral reef structure provides habitat for marine life and helps break up waves as they approach the coastline.

Orthomosaic images of Matanzas, Florida, from (a) before and (b) after Hurricane Matthew, and (c) a digital elevation model (DEM) showing the associated topographic change. Note, these results were produced by applying Structure-from-Motion (SfM) to NOAA oblique photographs, but similar results can be obtained using UAS aerial imagery.

Multicores collected from the northern Gulf of Mexico. These cores contain roughly 1 meter of sediment from the seafloor, and represent the past ~2000 years of deposition.

Low dunes near Cape Canaveral launch pads 39A and 39B often overwash during storm events, transporting sand landward. Critical infrastructure may be buried or flooded. In addition, significant landward transport of sand may lead to extensive shoreline erosion.
