Topographic datasets compiled for the Lower Roanoke River corridor in 2003, 2014, and 2020

This data release contains topographic information compiled for the Lower Roanoke River corridor located in eastern North Carolina. The Lower Roanoke River corridor includes the mainstem of the Roanoke River from Roanoke Rapids, NC (below the Roanoke Rapids dam) to the mouth of the Roanoke River at its confluence with the Albemarle Sound, and the associated floodplains and wetland areas surrounding the river. All datasets were derived from publicly available airborne light detection and radar (lidar) data collected in years 2003, 2014, and 2020. Data are organized into four categories: Digital Elevation Models (DEMs), Slopes, Digital Elevation Models of Difference (DoDs) in numeric format, and one DoD in categoric format. The DEM and Slope datasets represent static topographic conditions in 2003, 2014, or 2020. The DoD datasets reflect changes to topographic conditions between the years of 2003 and 2014, 2014 and 2020, and 2003 and 2020. These datasets can be used to support future examination of geomorphologic changes in the Lower Roanoke River basin. Due to the Lower Roanoke River corridor's extensive low-lying floodplain network, the lidar data and subsequent estimations of ground elevations (DEMs) were sensitive to differences in river stages across airborne lidar flight dates. Dense canopy cover and changes to lidar collection and processing techniques across the data acquisition years may also have affected the quality of data contained in this release.
This data release contains four .zip files:
(1) "DEM_3m.zip" contains three digital elevation model raster datasets in GeoTIFF format representing bare earth ground elevations in the years 2003, 2014, and 2020 and one metadata file in .xml format that describes the three digital elevation models.
(2) "Slope_3m.zip" contains three slope raster datasets in GeoTIFF format representing bare earth ground slopes in the years 2003, 2014, and 2020 and one metadata file in .xml format that describes the three slope rasters.
(3) "DoD_numeric_3m.zip" contains three digital elevation difference model raster datasets in GeoTIFF format representing bare earth ground elevation changes between the years 2003 and 2014, 2014 and 2020, and 2003 and 2020 and one metadata file in .xml format that describes the three digital elevation difference models. 
(4) "DoD_categoric_3m.zip" contains one digital elevation class difference raster dataset in GeoTIFF format representing bare earth ground class changes between the years 2003 and 2014, 2014 and 2020, and 2003 and 2020 and one metadata file in .xml format that describes the digital elevation class change models.

Unfiltered surface water chemistry from the San Juan River watershed, 2021-2022, Four Corners USA

Elevated concentrations of metals including aluminum, arsenic, and lead were identified by Navajo Nation Environmental Protection Agency staff in the San Juan River from below the Navajo Dam, through the Navajo Nation to Mexican Hat, Utah in the Four Corners Region of the United States (Colorado, Arizona, New Mexico, Utah).  An interdisciplinary team applied approaches and principles of geology, geochemistry, geomorphology, hydrology, and statistics to gain a better understanding of the tributaries supplying the source(s) of metals to the San Juan River. 15 sites along the San Juan River were sampled by the equal width increment method and composited in a churn during a baseflow synoptic sampling campaign in February 2021 (USGS, 2018).  Unfiltered water samples were collected in single-siphon samples and by grab sample at 59 ephemeral and perennial tributaries to the San Juan River in 2021 and 2022.  Eighteen surface water sites along the San Juan River were sampled as grab samples in 2021 and 2022.  The samples were analyzed for major and trace cations by inductively coupled plasma emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) at the US Geological Survey Analytical Chemistry Laboratory in Denver, Colorado. A total of 765 unfiltered samples were analyzed.

Code and data from Castro-Santos et al.: Sprinting performance and behavior of shortnose sturgeon

This data release includes the raw data and code used in Castro-Santos et al. (2024): Sprinting performance and behavior of adult shortnose sturgeon (Acipenser brevirostrum).  Notably, the code includes several processes used to differentiate among attempts, quantify attempt rate, distance traversed, and endurance of shortnose sturgeon ascending a telemetered flume.  The code can be readily adapted to other forms of telemetry analysis, in particulary with respect to processes associated with fish passage at barriers.  Additional code is provided that quantifies kinematics variables recorded for the sturgeon as they swam at high speeds in the flume.  The kinematics code was modified from Goerig et al (2021): https://doi.org/10.5061/dryad.bg79cnp9x

Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) and Other Chemical Constituents for Groundwater and Surface Water Samples on Western Cape Cod, Massachusetts, 2014-2019 (ver. 1.1, November 2025)

Groundwater, surface water, and associated quality assurance samples were collected downgradient of an abandoned fire training area and wastewater infiltration beds on western Cape Cod, Massachusetts and analyzed for per- and polyfluoroalkyl substances (PFAS) from 2014-2019.  Water-quality properties measured at the time of sample collection include pH, specific conductance, temperature, and dissolved oxygen. Samples were also analyzed for other chemical constituents including major and selected minor inorganic constituents, nutrients, and UV absorbance. Although selected results have been previously published in several data releases, this data release includes the entire suite of field and chemical constituents. PFAS concentration data tables were derived from multiple data sources: Barber and others, 2017; Ruyle and others, 2021; and Tokranov and others, 2021a and 2021b. Other field and chemical data were derived from those sources as well as from Hull and others, 2021 and Repert and others, 2023. PFAS data from different sources were converted to a uniform format.

Vulnerability of Groundwater Influenced Ecosystems in the Northeastern United States

Groundwater influenced ecosystems (GIEs) are increasingly vulnerable due to groundwater extraction, land use practices, and climate change. These ecosystems receive groundwater inflow, which can maintain water levels, water temperature, and chemistry necessary to sustain the biodiversity that they support. Many aquatic systems receive groundwater as a portion of their baseflow or water budget, and in some systems (e.g., springs, seeps, fens) this connection with groundwater is central to the system’s integrity and persistence. Groundwater management decisions for human use often do not consider the ecological effects of those actions on GIEs. This disparity can be attributed, in part, to a lack of information regarding the physical relationships these systems have with the surrounding landscape and climate, which may influence the environmental conditions and associated biodiversity. We estimate the vulnerability of GIEs in the Atlantic Highlands and Mixed Wood Plains EPA Level II Ecoregions in the northeastern United States. We represent vulnerability with variables describing adaptive capacity (topographic wetness index, hydric soil, physiographic diversity), exposure (climatic niche), and sensitivity (aquatic barriers, developed or agriculture areas).

Bedrock geochemistry, Dickinson County, Michigan

The southern margin of the Archean Superior Province in the central Upper Peninsula of Michigan records Paleoproterozoic tectonic events involved in the ~2.1 Ga rifting of the proposed Archean supercraton Superia and the subsequent assembly of Laurentia. Within a small area of Dickinson County, Michigan, there are many distinctive geologic units with confounding structural and stratigraphic relationships that are key to understanding the geologic and tectonic evolution of the region. The samples included in this data release were collected for geochemistry to complement recent geochronological (Vallini and others, 2006; Ayuso and others, 2018) and geophysical research (Drenth and others, 2021) in the region. The geochemical data encompass the diverse geologic units that crop out mainly in Dickinson County. These eighteen samples include rocks from the Dickinson Group (Solberg schist, Six Mile amphibolite, and East Branch arkose), as well as samples of the Bell Creek gneiss, Hardwood gneiss, porphyritic red granite, gray gneiss, and several of the mafic dikes that cut through the region. Samples were analyzed by ActLabs for major and trace elements.

Groundwater-Level Altitudes and Long-Term Groundwater-Level Changes in the Chicot and Evangeline (undifferentiated) and Jasper aquifers, greater Houston area, Texas, 2024

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated), and Jasper aquifer in the greater Houston area, Texas. This dataset shows current‐year (2024) groundwater‐level altitudes for each aquifer as well as 1–year (2023–24), and 5‐year (2019–24) groundwater‐level changes for each aquifer, long‐term (1990–2024 and 1977–2024) groundwater‐level changes for the Chicot and Evangeline aquifers (undifferentiated), and long‐term (2000–2024) groundwater‐level changes for the Jasper aquifer. The groundwater‐level measurements from which the dataset was built are stored in the USGS National Water Information System (NWIS), a publicly available, searchable, online database of water information (USGS, 2024).
In 2024, measured groundwater-level-altitudes for the Chicot and Evangeline aquifers (undifferentiated) ranged from about 320 feet (ft) below to about 205 ft above the North American Vertical Datum of 1988 (NAVD 88). Measured groundwater-level-altitudes for the Jasper aquifer ranged from about 266 ft below datum to about 234 ft above NAVD 88.

National Assessment of Oil and Gas Tuscaloosa and Woodbine Downdip Gas Assessment Units

The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources.  The Assessment Unit is defined within the context of the higher-level Total Petroleum System.  The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologists responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type.  The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies.  The only exceptions to this are Assessment Units that border the Federal-State water boundary.  In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary.
