Shown here is a colony of the threatened Elkhorn coral, Acropora palmata, in Dry Tortugas National Park that has become "bleached," that is, lost all its algal symbionts (also called zooxanthellae) because of the summer 2023 ocean-heat wave.

Coastal communities on the Great Lakes may experience coastal change, including dune erosion. The USGS and NOAA are developing the Total Water and Coastal Change Forecast at sites like this one in Ontanogan, Michigan to provide communities with real-time information for decision making.

Dr. Legna Torres-García participated in camper interviews for the 2023 Oceanography Camp for Girls, during which she explained the types of oceanographic equipment that is used to collect data to help create and improve coastal change hazard predictions.

The Caribbean Coastal Ocean Observing System (CARICOOS) hosted a General Assembly May 26, 2023, in San Juan, Puerto Rico, and featured a presentation about USGS coastal hazards research, shoreline change geonarrative, natural hazards web pages, and other research related to the island.

The R/V Weatherbird II docked at the Florida Institute of Oceanography at University of South Florida (USF) College of Marine Science in St. Petersburg, Florida. USGS scientists and partners at Eckerd College and USF load the vessel in preparation for a research cruise as part of a National Science Foundation (NSF)-funded Scientist-at-Sea program.
