Prospective regions for marine minerals on the Alaska Outer Continental Shelf

This shapefile is of prospective regional outlines of where marine minerals may occur on the Alaska Outer Continental Shelf (OCS). Polygons were hand digitized based on a U.S. Geological Survey (USGS) data review that considers the state of knowledge regarding marine mineral occurrences within the Alaska OCS. This data release is a companion to the USGS Professional Paper, Gartman and others, 2022

Chirp sub-bottom data collected in Lake Crescent, Washington during USGS field activity 2019-622-FA

Chirp sub-botttom data were acquired during USGS field activity 2019-622-FA in August of 2019. The survey was conducted in Lake Crescent, Washington. Geophysical mapping was conducted to investigate earthquake triggered mass transport deposits as part of the Cascaadia Earthquake recurrence project. These data and information are intended for science researchers, students, policy makers, and the ge

Computed tomography (CT) scans, photographs, X-ray fluorescence (XRF) scans, geochemistry, X-ray diffraction (XRD), and gamma-ray bulk density data of push cores from Loki's Castle and Favne vent fields, Mohns Ridge

This data release contains computed tomography (CT) scans, photographs, X-ray fluorescence (XRF) scans, geochemical data, X-ray diffractograms (XRD), and gamma-ray bulk density of push cores and sediment subsamples from those cores collected in 2018 and 2019 from Loki’s and Favne Vent Fields, Mohns Ridge, part of the Arctic Mid-Atlantic Ridge. For the geochemical section of the release, data inclu

Lead, Radium, Cesium, and Thorium isotope activity in sediment samples from Los Padres reservoir, Carmel River watershed, California

Sediment samples were collected from Los Padres reservoir in the Carmel River watershed, central California coast, between July 11 and 17, 2017, using a CME-45 barge-mounted drill rig, to characterize sedimentary properties in the reservoir deposits following the Soberanes Fire of 2016 and high river flows in winter 2017. Borehole samples were recovered using direct push coring with an Osterberg p

Composite multibeam bathymetry surface and data sources of the central Cascadia Margin offshore Oregon

In 2018 and 2019 the NOAA ships Rainier and Fairweather collected multibeam bathymetry data in 4 areas along the central Cascadia Margin offshore Oregon as part of a cooperative project between the U.S. Geological Survey, Pacific Coastal and Marine Science Center and NOAA. These regions were combined with other publicly available multibeam bathymetry data. The surface was generated to assist resea

Bathymetry, backscatter intensity, and benthic habitat offshore of Cape Mendocino, California

Survey data collected for this data release were used to create maps of surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). Funding was provided by the California Ocean Protection Council. These data are intended to provide

Swath bathymetry and acoustic-backscatter data collected in 2013 offshore Maui and Kaho`olawe, Hawaii, during field activity A-01-13-HW

Bathymetry and acoustic-backscatter data were collected during a February 2013 SWATHPlus survey offshore of the Hawaiian islands of Maui and Kaho`olawe (field activity number A-01-13-HW). The data are provided as 1-meter resolution GeoTIFF files.

Reprocessed single channel sparker seismic reflection data offshore central California from USGS field activities S-6-08-SC and S-6-09-SC

The U.S. Geological Survey collected high-resolution single channel minisparker data between Point Sal and Piedras Blancas in 2008 and 2009 with support from the Pacific Gas and Electric (PG&E) CRADA and the USGS Coastal and Marine Geology program. Reprocessing of this data in 2018 improved vertical resolution of the stratigraphy and structural deformation of the original data and was funded by an

Topographic survey data and digital elevation model of Oxbow Reservoir, Placer County, California, October 2022

This data release presents topographic survey data and a digital elevation model (DEM) of Oxbow Reservoir, in Placer County, California. The U.S. Geological Survey (USGS) conducted a topographic survey of accessible regions of the reservoir sediment on 26 October 2022, when the reservoir was partially de-watered to allow repairs to the dam infrastructure following the Mosquito Fire. The survey was

Radiocarbon age dating of biological material from cores collected off central California in 1999, 2006, and 2019

Results of radiocarbon age dating of planktic and benthic foraminifera collected from cores obtained in 1999, 2006, and 2019 offshore central California in the vicinity of Morro Bay.

Minisparker and chirp seismic reflection data acquired offshore San Francisco and Pacifica during USGS field activity S-16-10-NC

Chirp sub-bottom and single-channel minisparker seismic reflection data were collected by the U.S. Geological Survey in August 2010, offshore San Mateo County, California. Data were collected aboard the R/V Snavely during field activity S-16-10-NC. This work was funded by the USGS Coastal and Marine Geology Program's Coastal and Marine Catastrophic Hazards project. The high-resolution seismic-refl

Bathymetry, backscatter intensity, and benthic habitat offshore of the Eel River, California

Survey data collected for this data release were used to create maps of surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA).
