Data

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 to climate

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 influence. S

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 water year

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.

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 storms account

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

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-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

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

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

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
