The U.S. Geological Survey is conducting research to guide the restoration and recovery of threatened corals in Dry Tortugas National Park and throughout the western Atlantic. Shown here are two colonies of the threatened elkhorn coral, Acropora palmata, with a colony of staghorn coral, Acropora cervicornis, in the center.

The U.S. Geological Survey is conducting research to guide the restoration and recovery of threatened corals in Dry Tortugas National Park and throughout the western Atlantic. Shown here is a colony of the threatened elkhorn coral, Acropora palmata, that has grown over the sides of a cinderblock experimental platform.

A vibracore being deployed by USGS staff from the FSU R/V Apalachee for the Naval Research Laboratory (NRL). The objective of this field effort was to establish a baseline environmental characterization for a test bed to predict mobility and burial of unexploded ordnance (UXO) in response to waves and currents. 

The USGS Processes Impacting Seafloor Change and Ecosystem Services (PISCES) project team meeting at the St. Petersburg Coastal and Marine Science Center in May 2022 to coordinate Structure-from-motion (SfM) Quantitative Underwater Imaging Device with 5 cameras (SQUID-5) and diver-based SfM data acquisition and processing for field work.

Our coasts, the most familiar part of the ocean are the gateway to the larger deeper ocean world. USGS studies processes and hazards in the coastal zone and how they affect people, wildlife, and ecosystems.

In the background, Andy Farmer (SPCMSC) and Gerry Hatcher (PCMSC) prep the R/V Sallenger, the vessel being used to tow the device. 

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 Scientists-at-Sea program.

Screenshot of an idealized animation of tsunamis produced by the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai volcano in the Kingdom of Tonga. View to the north-northeast. The fastest water wave to radiate away from the eruption is being pushed by an atmospheric wave triggered by the explosion.

BJ Reynolds of the St. Petersburg Coastal and Marine Science Center operates a personal watercraft near the shoreline of Seven Mile Island, New Jersey. This vessel is used to collect single beam bathymetry (depth and seafloor shape) in the nearshore, and the equipment on the shoreline is used to collect chirp seismic reflection on the shoreface and inner shelf.
