Data

Geochemical analysis of carbonate rock samples collected from seep fields on the RB1903 and AT41 research expeditions in the U.S. Mid- and South Atlantic. Samples were collected as a fingerprint to past hydrocarbon seep activity, fluid source, and depositional environment.

Surveys offshore of Point Buchon, California, were conducted to map 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). These data are intended to provide regional bathymetric information in California State...

Five-stage sequential extractions were performed on ultramafic soil from Bosque Susua and Guanica Dry Forest, stream sediment from Rios Loco and Yauco, and nearshore sediment from Guanica Bay in southwest Puerto Rico. Sequential extractions showed partitioning of geologically enriched metals and other elements among five phases: 1) adsorbed and calcium-bound, 2) iron-, manganese...

This data release supersedes version 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5. Versioning details are documented in the accompanying VersionHistory_P99MJ096.txt file. Various water column variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, dissolved inorganic carbon, radio-carbon isotopes were measured in samples collected using...

This dataset archives geochronology and geochemistry measurements from detrital zircons collected from samples taken from the Bering Sea and its major feeder rivers.

This data release supersedes version 1.0, published in March 2021 at https://doi.org/10.5066/P9V7ODDR. Versioning details are documented in the accompanying VersionHistory_P9K2GOAL.txt file. Various water column variables, including salinity, dissolved inorganic nutrients, dissolved inorganic carbon, and radio-carbon isotopes were measured in samples collected using a Niskin-bottle...

This data release supersedes version 1.0, published in August 2020 at https://doi.org/10.5066/P9ZS1JX8. Versioning details are documented in the accompanying VersionHistory_P9JKYWQU.txt file. Various water column variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, dissolved inorganic carbon, were measured in samples collected using a Niskin-bottle rosette...

Hourly time-series of waves at the 20m, 50m, and 100m isobaths, along all U.S. open coasts for the historical (1979-2014) and projected (2020-2050) period: Those data (estimates of historical and long-term future conditions) were developed by running the National Oceanic and Atmospheric Administration's (NOAA) WaveWatch3 wave model forced with winds and sea ice extents from four separate...

CTD (Conductivity Temperature Depth) data were collected October-November 2019 offshore of California and Oregon as part of the ongoing EXPRESS: Expanding Pacific Research and Exploration of Submerged Systems project. The data were collected using an SBE 49 FastCAT V 1.2a CTD profiler attached to the “Yogi” ROV launched from the National Oceanic and Atmospheric Administration’s (NOAA’s)...

In 2008, the U.S. Geological Survey began mapping the main channel and shallow intertidal mudflats between the Dumbarton Bridge and a railroad bridge located 1 km to the south in south San Francisco Bay. This information was collected to document bathymetric change before and after restoration to inform the South Bay Salt Pond Restoration Project (https://www.southbayrestoration.org)...

An extensive set of physics-based XBeach Non-hydrostatic hydrodynamic model simulations (with input files here included) were used to evaluate the influence of shore-normal reef channels on flooding along fringing reef-lined coasts, specifically during extreme wave conditions when the risk for coastal flooding and the resulting impact to coastal communities is greatest. These input files...

Underwater images were collected using a towed-surface vehicle with multiple downward-looking underwater cameras developed by the U.S. Geological Survey (USGS). The system is named the Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with Five Cameras (SQUID-5). The raw images and associated navigation data were collected at Eastern Dry Rocks, a coral reef located...
