The USGS Utah Water Science Center and the Woods Hole Coastal and Marine Science Center conducted a collaborative geophysical research effort within Lake Powell, UT-AZ to map the bathymetry of the lake and characterize shallow sediment deposition near the mouths of the San Juan and Colorado Rivers.

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.
