The U.S. Geological Survey (USGS) collected field survey data and developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models for selected stream crossing sites in the Squannacook River Basin, north-central Massachusetts. A Geographic Information System (GIS) was developed to derive model input data from Light Detection and Ranging (lidar) Digital Elevation Models (DEM) at each stream crossing location. Hydraulic models were built for existing culvert designs as well as preliminary culvert designs for a 3-sided box, 3-sided arch, and a pipe culvert using field survey and GIS data. The preliminary culvert models were designed to convey...

Data includes fish abundance and habitat data collected at ten sites in the Sandusky River, OH. Fish were collected using two 3.67 m long hoop nets with an initial hoop diameter of 0.91 m. Nets were set perpendicular to the current, opening toward the shoreline. Nets were set for approximately 24 hours and catch rates for each set were defined as the number of fish caught in the two hoop nets per 24-hour sampling period. Fish were identified to species, measured for total length (mm), and released. Water quality was taken daily at each site at approximately the same time of day with a YSI Exo2 multiparameter sonde. Physical habitat data was recorded at the start of each trial. Vegetation coverage was characterized...

From 2010-2018 we investigated the occurrence of avian influenza antibody in wild birds in Iceland. A total of 2453 serum samples were collected from wild birds. We tested all samples by enzyme-linked immunosorbent assay (ELISA) for evidence of previous exposure to avian influenza virus with 1302 testing positive.

This Data Release accompanies the publication "State of stress in areas of active unconventional oil and gas development in North America" by J.-E. Lund Snee (now J.-E. Lundstern) and M.D. Zoback (2022) in the AAPG Bulletin. This dataset provides maximum horizontal stress (SHmax) orientation and relative stress magnitude (faulting regime) information that comprise a new-generation crustal stress map for North America. Relative stress magnitudes are presented using the Aϕ (A_phi) parameter, a single scalar that represents the ratio of the three principal stress magnitudes. Data were collected between 2015 and 2022. Data points for SHmax orientations, relative stress magnitudes, and the earthquake focal mechanisms...

Provided here is a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. This dataset contains more than 23,908 earthquakes in 346 well distributed clusters. Currently there are more than 4M arrival times with the majority being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully...

The final inverted resistivity models within the “Airborne electromagnetic surveys of the Mississippi Alluvial Plain and Chicot Aquifer System, March 2018 and May - August 2021: Resistivity Models” child item are broken up according to the three main objectives of these surveys: River surveys along the thalweg of major rivers with the MAP and the Chicot Aquifer extents; Levee surveys along the Mississippi and Arkansas rivers from Cairo, IL to Baton Rouge, LA and northwest from the confluence of the Mississippi and Arkansas rivers to Pine Bluff, AR; and gridded products mainly focused on gravel bars within the Mississippi River from Helena, MS to the confluence with the Arkansas River. The data in this child item...

The dataset consists of two csv files one for home range and net displacement analysis for adult snakes with at least 20 locations collected during the study period and one for the analysis of movement metrics for all adult snakes in the study. The home range data contains the calculated 100 percent and 95 percent minimum convex polygons (MCP) and 95 percent adaptive local convex hull (a-LoCoH) home range estimates, 3 measures of net displacement from the release location of the snake as well as other pertinent information about individual snakes (year included in study, id, treatment group, site, snout to vent length (SVL)). The movement data contains calculations of the following movement metrics: sinuosity, start-to-end...

This is a dataset containing aggregated non-native plant occurrence and abundance data for the contiguous United States. We used these data to develop habitat suitability models for species found in the Eastern United States using locations with 5% cover or greater. We adapted the INHABIT modeling workflow (Young et al. 2020), using a consistent set of climatic predictors that were important in the INHABIT models. We developed models using five algorithms with VisTrails: Software for Assisted Habitat Modeling [SAHM 2.2.2]. We accounted for sampling bias by using the target background approach, and constructed model ensembles using the five models for each species for three different thresholds (conservative to targeted;1st...

This shapefile includes strike and dip information for the area of the Stillwater Complex, located in southwestern Montana. This dataset was created from pre-existing digital strike and dip information and from digitizing strike and dip locations from georeferenced map images. The data includes information about the strike and dip locations; the geologic unit and rock type the measurement was taken on; information about the source map, such as map title and scale; and other miscellaneous information. Version 2.0 includes additional strike and dip measurements and updated locations for many points resulting from maps that were re-georeferenced using high resolution lidar. For access to the previous version of this...
