Simulated coastal fine-grained sediment plumes from beach nourishment near Santa Barbara, California Simulated coastal fine-grained sediment plumes from beach nourishment near Santa Barbara, California
A coupled hydrodynamic and sediment transport model was developed to simulate the dispersal of fine-grained sediment from beach nourishment projects near Santa Barbara, California. The model simulations were used to quantify the size and extent of sediment plumes resulting from nourishment projects and evaluate the potential impacts of beneficial use of fluvial sediment captured in...
Aeolian sediment-trap data from the Colorado River corridor in Grand Canyon National Park, Arizona Aeolian sediment-trap data from the Colorado River corridor in Grand Canyon National Park, Arizona
Samples of aeolian (wind-transported) sediment were collected between 2003 and 2010 at multiple locations along the Colorado River corridor within Grand Canyon National Park, Arizona. At each site, sediment being actively transported by wind were collected using a set of four vertically stacked passive samplers (Big Spring Number Eight [BSNE] sand traps). Sediment samples were collected...
Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui Benthic habitat map of the geomorphological structure, biological cover, and geologic zonation of Olowalu reef, Maui
This shapefile contains habitat polygons identifying the dominant and major geomorphological structure, biological type and percent cover, and geologic zone for 11 square kilometers of Olowalu reef off west-central Maui at a minimum mapping unit of 100 square meters. Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2)...
Multibeam line files from Cross Sound, Alaska collected during USGS field activity 2015-629-FA Multibeam line files from Cross Sound, Alaska collected during USGS field activity 2015-629-FA
In 2015 the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) in cooperation with the Alaska Department of Fish and Game (ADFG) collected bathymetry and acoustic backscatter data offshore Cross Sound in southeast Alaska using an Reson 7111 multibeam echosounder mounded to the ADFG R/V Solstice. The survey was conducted to map the offshore expression of the...
Satellite-derived shorelines for the U.S. states of Oregon and Washington for the period 1984-2023, obtained using CoastSat Satellite-derived shorelines for the U.S. states of Oregon and Washington for the period 1984-2023, obtained using CoastSat
This dataset contains shoreline positions derived from available Landsat satellite imagery for two states (Oregon, and Washington) along the U.S. Pacific coast for the time period 1984 to 2023. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are presented in...
Detailed Aeromagnetic Survey of the Trinidad Area, California Detailed Aeromagnetic Survey of the Trinidad Area, California
This data release provides access to a low-altitude, aeromagnetic survey of a part of northwestern California. These data were acquired to support earthquake and tsunami hazard investigations and geologic mapping of the greater Trinidad area of northwestern California. Magnetic data are provided as a database and the residual magnetic intensity is provided as a grid.
Sediment core data from offshore Cascadia during field activity 2022-653-FA Sediment core data from offshore Cascadia during field activity 2022-653-FA
This data release contains sediment core data including X-ray Computed Tomography (CT) scans, photos, and multi-sensor core logger (MSCL) data. Sediment cores were collected along the Cascadia Subduction Zone (offshore northern California, Oregon and Washington) during U.S. Geological Survey cruise 2022-653-FA aboard the M/V Bold-Horizon. The cores were collected to evaluate potential...
Labeled satellite imagery for training machine learning semantic segmentation models of coastal shorelines Labeled satellite imagery for training machine learning semantic segmentation models of coastal shorelines
A collection of data releases containing labeled satellite imagery for the purpose of training Machine Learning models to automate the task of shoreline extraction from satellite imagery. Shoreline mapping from satellite imagery, known as Satellite-Derived Shorelines or SDS, has the potential to transform coastal shoreline mapping for erosion hazard mapping and coastal resource...

This data release contains computed tomography (CT) scans, photographs, geochemistry, grain-size and total carbon analysis, X-ray fluorescence (XRF) scans, X-ray diffraction (XRD), magnetic susceptibility, and gamma-ray bulk density data of gravity cores, push cores, and sediment subsamples from those cores collected in 2022 from the Escanaba Trough vent field, Gorda Ridge, in the...
Properties of sediment collected from channels in northern San Francisco Bay, California, 2024 Properties of sediment collected from channels in northern San Francisco Bay, California, 2024
Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top...
