The U.S. Geological Survey (USGS) created geospatial datasets of potential culvert locations along with flowlines connected toLake Huron as part of the Saginaw Bay Restoration Assessment (SBRA). The Degree Flowlines and Culverts datasets represent the flowline network and culverts in the SBRA study area. Both datasets will be served in the Great Lakes Wetlands Restoration Area mapping...

This dataset contains all the layers associated with U.S. Geological Survey (USGS) Great Lakes Coastal Wetland Restoration Assessment (GLCWRA) initiative for the Saginaw Bay Restoration Assessment (SBRA) which aims to identify and rank coastal areas with the greatest potential for wetland habitat restoration. Each layer has a unique contribution to the identification of restorable...

This dataset represenst the location of dikes within the Saginaw Bay Restoration Assessment (SBRA) study area. An ArcGIS model identified dikes as having a difference in elevation and slope above a certain threshold. If the elevation difference was below a certain threshold, the area was not considered a dike. However, if the difference in elevation between two points was significantly...

This dataset contains observations of the distribution of end-of-summer snow cover on approximately 3000 glaciers across Alaska and Northwest Canada. The data are provided as: (1) GeoTIFF rasters indicating the spatial extent of end-of-summer snow cover on each glacier's surface in each year (one raster per glacier per year), and (2) yearly tables with the equilibrium line altitude and...

This dataset includes processed ground-motion records and horizontal pseudospectral accelerations (5-percent-damped) from magnitude 3.0-6.8 earthquakes occurring in the vicinity of Portland, Oregon, between 2005 and 2022. The dataset includes 347 records from 134 earthquakes and 69 stations. Spectral values are provided at 21 periods (0.01-10 s). It also includes the basin depth models...

This dataset includes processed ground-motion records and horizontal pseudospectral accelerations (5-percent-damped) from magnitude 3.0-6.0 earthquakes occurring in the vicinity of Reno, Nevada, between 2008 and 2022. The dataset includes 592 records from 104 earthquakes and 42 stations. Spectral values are provided at 21 periods (0.01-10 s). Local basin depths as given by Z1.0 and Z2.5...

This dataset includes processed ground-motion records and horizontal pseudospectral accelerations (5-percent-damped) from magnitude 3.5-7.1 earthquakes occurring in the vicinity of the Great Valley, California, between 2000 and 2022. The dataset includes 12,044 records from 564 earthquakes and 254 stations. Spectral values are provided at 21 periods (0.01-10 s). It also includes the...

This data release contains a dataset that depicts fault scarps along the Zapata and Blanca sections of the Sangre de Cristo fault zone located in the San Luis basin of southern Colorado. The Zapata and Blanca sections extend from the Great Sand Dunes National Park and Preserve to the Blanca Peak massif and are differentiated by a sharp change in fault zone orientation from north-south to...

The University of Wyoming Stream Species Dataset is a species presence dataset containing presence locations for 116 freshwater fish species in Wyoming, Montana, and the surrounding states. It contains data from 40,490 unique sample events (location, month, year). Data was derived from multiple sources (Table 1) and limited to fish occurrences in rivers and streams.

This data release is a compilation of a literature search of published core X-ray diffraction (XRD) data for the Permian Basin Barnett and Woodford Shales, and includes data from: the Reliance Triple Crown 1 (RTC 1) well of Pecos County, Texas; Fasken Fee BM SWD 1 well of Andrews County, Texas; the M G Nevill well of Culberson County, Texas; the Mesquite 1 well of Hamilton County, Texas...

The U.S. Geological Survey (USGS) collected rock magnetic susceptibility and density measurements to understand the causative sources of airborne magnetic and ground gravity survey anomalies in the Wet Mountains, Colorado. A total of 609 magnetic susceptibility and 86 density measurements were collected from outcrops and hand samples, respectively, from July 2022 to June 2023. These...

This data set is an amalgamation of records of marine and coastal species occurrence in the Boston Harbor. Taxon include marine mammals, shorebirds, fish, marine invertebrates, and marine macro algae. The earliest record acquired was from 1861. Records span through 2020. We curated records from federal and state agencies, peer reviewed and gray literature, and scientific grade research
