Data Releases

The data release contains programmed pyrolysis data generated in the Petroleum Geochemistry Research Laboratory that was used to determine the precision and accuracy of daily operating standards for the Petroleum Geochemistry Research Laboratory Programmed Pyrolysis Method.

An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at Lone Tree Point, Kiket Bay, Washington on June 5, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive a high-resolution digital surface model (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of the suba

An unmanned aerial system (UAS) was used to acquire high-resolution imagery of the intertidal zone at West Whidbey Island, Washington on June 4, 2019. This imagery was processed using structure-from-motion (SfM) photogrammetric techniques to derive a high-resolution digital surface model (DSM), orthomosaic imagery, and topographic point clouds. In order to maximize the extent of the subaerially

This data release contains calculated metrics which summarize various biodiversity and functional/life history trait information about fish communities sampled across the Chesapeake Bay Watershed as well as ancillary data related to time/place of sampling and sampling methodology. The fish sampling data used to compute these metrics were compiled from various fish sampling programs conducted by st

Various water column variables, including salinity, dissolved inorganic nutrients, pH, total alkalinity, dissolved inorganic carbon, radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from sites offshore of California and Oregon from October to November 2018 during NOAA cruise SH-18-12 on the R/V Bell M. Shimada (USGS field activity 2018-663-F

This product provides spatial variations in wave thrust along shorelines in Massachusetts and Rhode Island. Natural features of relevance along the State coast are salt marshes. In recent times, marshes have been eroding primarily through lateral erosion. Wave thrust represents a metric of wave attack acting on marsh edges. The wave thrust is calculated as the vertical integral of the dynamic pres

This product provides spatial variations in wave thrust along shorelines in the Chesapeake Bay. Natural features of relevance along the Bay coast are salt marshes. In recent times, marshes have been eroding primarily through lateral erosion. Wave thrust represents a metric of wave attack acting on marsh edges. The wave thrust is calculated as the vertical integral of the dynamic pressure of waves.

The National Assessment of Coastal Change Hazards project exists to understand and predict storm impacts to our nation's coastlines. This data release defines the alongshore extent of overwash deposits, determined from aerial photograph analysis, attributed to coastal processes during storm events. Note: This data release was versioned on June 11, 2024. Please see the Suggested Citation section f

The U.S. Geological Survey's SPAtially Referenced Regression On Watershed attributes (SPARROW) for the Southeastern United States was used to simulate changes in total nitrogen, total phosphorus and suspended sediment load in streams under two scenarios: (1) where all forests are urbanized and (2) where all forests are urbanized and runoff is adjusted based on a non-forested landscape. This data r

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS - SPCSMC), conducted a single-beam bathymetry survey within Grand Bay and Point Aux Chenes Bay, Mississippi/Alabama, from March 3-6, 2021. Efforts were supported by the Estuarine and MaRsh Geology project (EMRG), and the data described will provide baseline bathymetric infor

The Trans-Pecos region of West Texas and Southern New Mexico contains a series of rare earth element (REE) enriched ~ 34-36 Ma intrusive rhyolites and syenites. One such intrusive in the Sierra Blanca Mountains, Texas, hosts the Round Top REE deposit which is one of the few REE deposits in the U.S. with an economic evaluation and is scheduled to go into production in 2025. In addition, Alkaline ig

Synthetic aperture radar (SAR) data for 2015 through 2018 from the European Space Agency's (ESA) Sentinel-1A satellite were acquired from the Alaskan Satellite Facility and used to generate spatially detailed land-surface deformation maps (interferograms) for the Pajaro Valley using conventional Interferometric Synthetic Aperture Radar (InSAR) workflows.
