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.

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.

The fastest water wave to radiate away from the eruption is being pushed by an atmospheric wave triggered by the explosion.

A digital elevation model (DEM) was created from underwater images collected at Eastern Dry Rocks coral reef near Key West, Florida, in May 2021 using the SQUID-5 camera system. The underwater images were processed using Structure-from-Motion (SfM) photogrammetry techniques into a classified two-class ('unclassified' and 'low noise') 3D point cloud.

Noa Randall and Rachel Allen are installing an optical turbidity sensor on the mudflats in Wellfleet harbor, to pair with the altimeter run by the Center for Coastal Studies.  The Herring River, which drains into Wellfleet Harbor, is slated to have its 100-yo dam removed in the next 6 months, with the potential to dramatically increase the sediment load and sus

Scientists collected sand auger cores from Fire Island to help reconstruct the evolution of the barrier over the last several centuries, with the goal of quantifying changes in sediment input and partitioning through time (e.g., how sand is distributed between the terrestrial portion of the barrier and the beach/shoreface).

In collaboration with the National Park Service, Woods Hole Oceanographic Institution, and the Vesta Corporation, the Environmental Geosciences group researched a new approach to climate change mitigation. The team led an experiment at the Herring River site as a first examination.
