A USGS scientist surveys GPS Ground Control Point locations on North Topsail Beach and within the Camp Lejeune Marine Corps Base, North Carolina. These data are used to validate previously surveyed aerial imagery and aid in Structure from Motion (SFM) processing. Specifically, this scientist was collecting data to look at coastal change due to Hurricane Florence.

USGS researchers have been monitoring changes in a breach in the island that occurred during Hurricane Sandy (modified from  Hapke et al., 2017). 
 

The CMHRP has been conducting scientific investigations at Fire Island in order to protect natural and cultural resources.

The PCMSC research vessel R/V Parke Snavely heads out of the Vallejo Marina on June 11, 2019 to deploy instrument frames in Grizzly Bay for the ERO19 study.

Lukas Winkler-Prins checks on the frame setup on June 10, 2019.  This tripod has an RBR CTD, an RBR bursting pressure sensor, an RBR optical backscatter sensor, a LISST-200X, an altimeter, and two Nortek ADVs + Seapoint optical backscatter sensors, which will reveal information about water temperature and salinity, wave height and period, total s

USGS studies the growth rates of corals at a network of coral growth assessment stations throughout Buck Island National Monument in St. Croix, U.S. Virgin Islands. These data provide resource managers with information needed to understand how coral populations are doing in the park.

The USGS Pacific and Coastal Marine Science Center collected data to investigate sediment dynamics in the shallows of San Pablo Bay in two deployments: February to March 2011 (ITX11) and May to June 2012 (ITX12). This data release includes time-series data and grain-size distributions from sediment grabs collected during the deployments.

The U.S. Geological Survey is conducting research to guide the recovery of the threatened Elkhorn coral, Acropora palmata, in Dry Tortugas National Park and throughout the western Atlantic.

In the aftermath of the 2018 Carr Fire, northern California, sediment has eroded from burned hillslopes and accumulated in some areas of Whiskeytown Lake. A recent sediment deposit is shown here in the Whiskey Creek section of the lake.

Jessica Rodysill (Reston) and Hunter Wilcox (SPCMSC) deploying a corer in Lake Enriquillo. The scientists will use the cores to construct precipitation changes in Dominican Republic over the late Holocene (~5000 years ago to present) time period.

Lauren Toth (Research Physical Scientist, SPCMSC) and collaborator Mike Colella (Florida Fish and Wildlife Conservation Commission) collect measurements of reef erosion at Molasses reef off Key Largo, FL.

SPMSC scientist Lauren Toth conducts a photographic survey of Porter Patch reef off Key Largo, one of the sites that has been surveyed as part of FWRI’s Coral Reef Ecosystem Monitoring project since 1996.

On March 25th, 2019, ocean engineer Rob Wyland of the Pacific Coastal and Marine Science Center gave a tour and demonstration to roughly a dozen students from the engineering class he teaches at Cabrillo College, a local community college.

Computer images showing the coastal cliff area of Mud Creek on the Big Sur coastline, central California, where on May 20, 2017 a catastrophic landslide destroyed over 400 meters of scenic California State Highway 1. These illustrations show the changes to the digital surface models of Mud Creek during the three primary phases of the landslide: (

USGS photographs taken from a contracted small airplane are used to build three-dimensional representations of the hillslopes of Big Sur, California, as shown here for the Mud Creek landslide site in 2017.  Blue symbols show the locations of individual photos obtained on the flight, and the gray area shows the hillslope landscape created from the photos using S

Map showing the surficial geology from this study and Baldwin and others (2016) with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.

Aerial photographs were collected from a small, fixed-wing aircraft over the coast of Barter Island, Alaska on July 01 2014, September 07 2014. Precise aircraft position information and structure-from-motion photogrammetric methods were combined to derive a high-resolution orthophotomosaic.
