California shorelines and shoreline change data, 1998-2016 California shorelines and shoreline change data, 1998-2016
This data release contains mean high water (MHW) shorelines along the coast of California for the years 1998/2002, 2015, and 2016, extracted from Light Detection and Ranging (LiDAR) digital elevation models using ArcGIS. The Digital Shoreline Analysis System (DSAS) was used to calculate net shoreline movement (NSM) between the pre-El Nino (2015) and post-El Nino (2016) shorelines, as a...
Hydrodynamic and sediment transport data from San Pablo Bay and Grizzly Bay, California, 2019 Hydrodynamic and sediment transport data from San Pablo Bay and Grizzly Bay, California, 2019
The U.S. Geological Survey Pacific Coastal and Marine Science Center collected hydrodynamic and sediment-transport data at shallow water sites in San Pablo Bay and Grizzly Bay, in northern San Francisco Bay between June and November 2019. The data were collected to determine hydrodynamic forcing, bed roughness, suspended-sediment concentration, and physical properties of the sediment bed...
Near-bed velocity measurements in Monterey Bay during arrival of the 2010 Chile Tsunami Near-bed velocity measurements in Monterey Bay during arrival of the 2010 Chile Tsunami
On February 27, 2010, a tsunami originating near Chile arrived in Monterey Bay, California. This data release comprises two hours of pressure and near-bed velocity data spanning the largest tsunami waves. At the time, the U.S. Geological Survey Pacific Coastal and Marine Science Center had a remotely-controlled instrumented platform deployed adjacent to the Santa Cruz Municipal Wharf...
Pilot study on bathymetric change analyses in the Sacramento-San Joaquin Delta, California Pilot study on bathymetric change analyses in the Sacramento-San Joaquin Delta, California
The bathymetry of the Sacramento-San Joaquin Delta affects the flow of water and sediment throughout the system and is a basic control on levee stability, habitat distribution, and water quality. Delta bathymetry is dynamic, responding to both natural forces and human activities. Assessment of future Delta conditions is aided by understanding how its bathymetry has changed in the past...
Geochemistry of fine-grained sediment in Bellingham Bay, Nooksack River, and small creeks from June 2017 to September 2019 Geochemistry of fine-grained sediment in Bellingham Bay, Nooksack River, and small creeks from June 2017 to September 2019
Elemental compositions are reported for the fine fraction of surface sediments from Bellingham Bay (June 2017 and March 2019) and in the fine fraction of streambank sediment from the Nooksack River (September 2017, March 2019, September 2019), Squalicum Creek (March and September 2019), Whatcom Creek (March and September 2019), and Padden Creek (March and September 2019). Major oxide...
A GIS compilation of vector shorelines and coastal bluff edge positions, and associated rate-of-change data for Barter Island, Alaska A GIS compilation of vector shorelines and coastal bluff edge positions, and associated rate-of-change data for Barter Island, Alaska
This dataset consists of rate-of-change statistics for the coastal bluffs and shorelines at Barter Island, Alaska, for the time period 1947 to 2020. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. A reference baseline was used as the originating point for the...
Bathymetry and acoustic-backscatter data collected in 2016 offshore the Elwha River mouth, Washington, during USGS Field Activity 2016-605-FA Bathymetry and acoustic-backscatter data collected in 2016 offshore the Elwha River mouth, Washington, during USGS Field Activity 2016-605-FA
This data release provides bathymetry and acoustic-backscatter data collected during a 2016 SWATHPlus-M survey offshore the Elwha River mouth, Strait of Juan de Fuca, Washington. Data were collected and processed by the U.S. Geological Survey, Pacific Coastal and Marine Science Center during field activity 2016-605-FA. This survey, along with two other surveys (Cochrane and others, 2008...
Bathymetry and acoustic backscatter data collected in 2008 offshore Tijuana River Estuary, California during USGS Field Activity S-5-08-SC Bathymetry and acoustic backscatter data collected in 2008 offshore Tijuana River Estuary, California during USGS Field Activity S-5-08-SC
In 2008 the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) collected bathymetry and acoustic-backscatter data offshore the Tijuana River Estuary, California. Mapping was conducted as part of the Tijuana Estuary Fine Sediment Fate and Transport Demonstration Project, which was developed by a number of State of California, federal, and private industry...
Radiocarbon dating of deep-sea black corals collected off the southeastern United States Radiocarbon dating of deep-sea black corals collected off the southeastern United States
Results of radiocarbon dating of deep-sea (500 m to 700 m) black corals are presented. These corals were collected off the southeastern United States as part of the Southeastern United States Deep-Sea Corals (SEADESC) Initiative.
Measurements of zinc, oxygen, and pH, from sphalerite and ZnS oxidation in seawater Measurements of zinc, oxygen, and pH, from sphalerite and ZnS oxidation in seawater
This data release presents the concentration of zinc, oxygen, pH, temperature, and the time point at which measurements were taken for experimental oxidation work regarding zinc and copper sulfide minerals. These data accompany the following publication: Gartman, A., Whisman, S.P., and Hein, J.R., 2020, Interactive oxidation of sphalerite and covellite in seawater: implications for...
Modeled 21st century storm surge, waves, and coastal flood hazards and supporting oceanographic and geological field data (2010 and 2011) for Arey and Barter Islands, Alaska and vicinity Modeled 21st century storm surge, waves, and coastal flood hazards and supporting oceanographic and geological field data (2010 and 2011) for Arey and Barter Islands, Alaska and vicinity
Changes in Arctic coastal ecosystems in response to global warming may be some of the most severe on the planet. A better understanding and analysis of the rates at which these changes are expected to occur over the coming decades is crucial in order to delineate high-priority areas that are likely to be affected by climate changes. The data provided in this release are part of a study...
Database to model three-dimensional flow over coral reef spur-and-groove morphology Database to model three-dimensional flow over coral reef spur-and-groove morphology
This data set consists of physics-based Delft3D-FLOW and SWAN hydrodynamic models input files used to study the wave-induced 3D flow over spur-and-groove (SAG) formations. SAG are a common and impressive characteristic of coral reefs. They are composed of a series of submerged shore-normal coral ridges (spurs) separated by shore-normal patches of sediment (grooves) on the fore reef of...
