Bathymetry, backscatter intensity, and benthic habitat offshore of the Eel River, California 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). Funding was provided by the California Ocean Protection Council.These data are intended...
Radiocarbon measurements, census counts of benthic foraminifera, diatoms, and palynomorphs, and geochemistry from core 721-1 obtained in 2002 off San Francisquito Creek in South San Francisco Bay Radiocarbon measurements, census counts of benthic foraminifera, diatoms, and palynomorphs, and geochemistry from core 721-1 obtained in 2002 off San Francisquito Creek in South San Francisco Bay
The urbanized area of downtown Menlo Park is subject to persistent flooding and sediment deposition by San Francisquito Creek in South San Francisco Bay. To mitigate these events, a suite of cores was collected in 2002 at the mouth of the creek to determine sediment depositional rates on the delta. One of those cores (721-1) was selected for microbiological (pollen, diatoms, and...
Digital maps of submarine landslides and mass wasting features offshore of southern California Digital maps of submarine landslides and mass wasting features offshore of southern California
This data release provides the locations and certain key metrics of landslide features offshore southern California, including landslide perimeters, scarps, evacuation zones, debris aprons, and slide-prone areas in geographic information system (GIS) shapefile format. The offshore region of southern California is a tectonically active area that includes more than 20 fault-bounded basins...
Sediment grain-size data from the Klamath estuary, California Sediment grain-size data from the Klamath estuary, California
Note: this data release has been deprecated. Find the updated version here: https://doi.org/10.5066/P13E57T8 This data release includes grain-size measurements of sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath estuary, northern California. Samples were collected using a BMH-60 bed-material sampler deployed from a boat, or by...
Grain-size data for sediment samples collected in Whiskeytown Lake, northern California, in 2018 and 2019 Grain-size data for sediment samples collected in Whiskeytown Lake, northern California, in 2018 and 2019
This data release supersedes version 1.0, published in July 2021 at https://doi.org/10.5066/P9BHOPEP. Versioning details are documented in the accompanying Whiskeytown_VersionHistory.txt file The Carr Fire ignited in northern California in July 2018, and ultimately burned almost 300,000 acres (approximately half on federal lands), resulting in a federal major-disaster declaration (DR...
Model input and projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State Model input and projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State
Model input and computed flood depths associated with the combined influence of sea level position, tides, storm surge, and streamflow under existing conditions and projected future higher sea level and peak stream runoff are provided for the lower (Reach 1) of the Nooksack River and delta in Whatcom County, western Washington State. The flood-depth projection data are provided in a...
Rain measurements in and near the Dolan Fire Area, Los Padres National Forest, California, 2022 to 2023 Rain measurements in and near the Dolan Fire Area, Los Padres National Forest, California, 2022 to 2023
Rainfall measurements were collected in and near the Dolan Fire burn area, Los Padres National Forest, California. The CZU Fire ignited in Los Padres National Forest, California, on August 18, 2020. By the time of full containment on December 31, 2020, the fire had burned 518 km2 (128,050 acres) in Monterey County. The U.S. Geological Survey (USGS) installed seven rain gages in and near...
Eelgrass and substrate characteristics in Bellingham Bay, Washington, July 2019 and July-August 2020 Eelgrass and substrate characteristics in Bellingham Bay, Washington, July 2019 and July-August 2020
Eelgrass (Zostera marina) characteristics, sediment grain size distributions, sediment total organic carbon contents (TOC), carbon isotope ratios of sediment organic matter, and total carbon to total nitrogen ratios were measured at four lower intertidal sites in Bellingham Bay, Washington, July 2-5, 2019, and three subtidal sites (grain-size and TOC only) on July 11, 2019.
Grain size, bulk density, and carbon content of sediment collected from Whale's Tail South marsh and adjacent bay floor, South San Francisco Bay, California, 2021-2022 (ver. 2.0, March 2025) Grain size, bulk density, and carbon content of sediment collected from Whale's Tail South marsh and adjacent bay floor, South San Francisco Bay, California, 2021-2022 (ver. 2.0, March 2025)
Sediment samples were collected on and adjacent to the Whale's Tail South marsh. Short push-cores of bed sediment were collected in South San Francisco Bay adjacent to Whale's Tail South marsh on five days from June through August 2021 and 3 days from November 2021 to January 2022. Additional samples were taken from ceramic tiles placed on the marsh to measure sediment deposition and...
High-resolution multichannel sparker seismic-reflection and chirp sub-bottom data acquired along the Cascadia margin during USGS field activity 2019-024-FA High-resolution multichannel sparker seismic-reflection and chirp sub-bottom data acquired along the Cascadia margin during USGS field activity 2019-024-FA
High-resolution multichannel sparker seismic (MCS) data and chirp sub-bottom data were collected by the U.S. Geological Survey in collaboration with the University of Washington (UW) in the summer of 2019 along the Cascadia submarine forearc offshore Oregon and Washington. Data were acquired to characterize quaternary deformation and sediment dynamics along the central and northern...
Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC
Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in 1990 in the California Continental Borderland (USGS field activity L490SC). In 2021, these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin. MCS data were acquired to support the Southern California Earthquake...
