Modeled surface waves from winds in South San Francisco Bay Modeled surface waves from winds in South San Francisco Bay
A model application using the phase-averaged wave model SWAN (in Delft3D) was developed to simulate wind waves in South San Francisco Bay, California, between 30 May 2021 and 19 May 2022. This data release describes the development of the model application, provides input files, and includes output from the model simulations in netCDF format. Model Application The model application...
Nearshore wave time-series along the coast of Alaska computed with a numerical wave model Nearshore wave time-series along the coast of Alaska computed with a numerical wave model
Alaska's Arctic coast has some of the highest erosion rates in the world. Erosion in the Arctic is primarily driven by permafrost thaw and wave activity. The warming climate decreases sea ice coverage, resulting in an increase in wave energy. To overcome the lack of available observational wave data in the nearshore, waves were downscaled with a numerical wave model (SWAN) utilizing...
Projected coastal flooding extents and depths for 1-, 20-, and 100-year return interval storms and 0.00, +0.25, +0.50, +1.00, +1.50, +2.00, and +3.00 meter sea-level rise scenarios in the Hawaiian, Mariana, and American Samoan Islands (ver. 2.0, September Projected coastal flooding extents and depths for 1-, 20-, and 100-year return interval storms and 0.00, +0.25, +0.50, +1.00, +1.50, +2.00, and +3.00 meter sea-level rise scenarios in the Hawaiian, Mariana, and American Samoan Islands (ver. 2.0, September
This data release provides flooding extent polygons and flood depth rasters (geotiffs) based on sea-level rise and wave-driven total water levels for the coast of the most populated Hawaiian, Mariana, and American Samoan Islands. Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding due...
Sediment grain size at river outlets along the California coast Sediment grain size at river outlets along the California coast
Fluvial sediment samples were collected from the lowermost reaches of 21 coastal watersheds in California, in order to characterize surficial grain size of river sediment from deposits that appeared to be recent based on field context. Samples were collected using a trowel to sample the uppermost 10 cm of sediment. Sampled locations included river-deposited sediment, upstream of tidal...
Salish Sea Hydrodynamic Model Salish Sea Hydrodynamic Model
A two-dimensional hydrodynamic model of the Salish Sea was constructed using the Delft3D Flexible Mesh Suite (Deltares, 2020) to simulate still water levels in the past and future and evaluate extreme recurrence water level events accounting for sea level rise and climate change. Three sets of model simulations were performed following Grossman and others (2023). The first simulated the...
Wave observations from bottom-mounted pressure sensors along the West side of Whidbey Island, Washington from Dec 2018 to Jan 2020 Wave observations from bottom-mounted pressure sensors along the West side of Whidbey Island, Washington from Dec 2018 to Jan 2020
Continuous water level measurements were made at 8 sites along a gradient in wave exposure on west Whidbey Island, Western Washington to characterize the wave climate and validate models of wave propagation.
Coastal hazards assessment associated with sea level rise and storms along the Whatcom County, Northwest Washington State coast Coastal hazards assessment associated with sea level rise and storms along the Whatcom County, Northwest Washington State coast
This product contains several datasets that map exposure to future forecasted hazards related to coastal flooding and extreme wave heights accounting for sea level rise (SLR) and climate change along the Whatcom County coast of northwestern Washington State in the Salish Sea. The SLR scenarios encompass a plausible range of projections by 2100 based on the best available science and...
Bathymetry, backscatter intensity, seismic reflection, and benthic habitat data offshore of Eureka, California Bathymetry, backscatter intensity, seismic reflection, and benthic habitat data offshore of Eureka, 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...
Prospective regions for marine minerals on the Alaska Outer Continental Shelf 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...
Chirp sub-bottom data collected in Lake Crescent, Washington during USGS field activity 2019-622-FA 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...
