Data Releases

This data release from the U.S. Geological Survey (USGS) presents the results of radiometric analyses conducted on sediment samples collected in 2016 and 2019 from Pahranagat Wash, behind Arrow Canyon Dam in northern Clark County, Nevada. In 2016, core samples were collected from two well sites: USGS 364453114483401 (ACWEST) and USGS 364448114481001 (ACEAST). Additionally, a shallow...

This data release comprises geospatial data of historical shoreline positions and long-term (greater than 60 years) and short-term (less than 40 years) rate of change statistics from the west coast of Alaska from Cape Prince of Wales to Kotlik River for the years 1949 to 2015.

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...

This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Cowardin, et al., (1979) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland...

The US Geological Survey has collected daily streamflow data at more than 20,000 locations within the conterminous United States (CONUS). Although these data are publicly available, there is little to no information about the environmental setting under which the data were collected. Specifically, users of the data have no readily available means to determine whether the observed...

This data release provides vector flight-line (point) and raster data for a high-resolution airborne magnetic and radiometric survey over a part of the eastern Great Basin, Nevada. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating...

This data release presents portable X-ray fluorescence (pXRF) data and physical properties (grain density, saturated bulk density, dry bulk density, and magnetic susceptibility) of 30 rock samples collected from an Earth MRI survey area in northeastern Washington, USA. Rock type information (age and lithology) are also included. The rock samples were initially collected for low...

This data release provides information on lake trout (Salvelinus namaycush) collected from 10 lakes located in Alaska's national parks. The data are in two tables: (1) capture information, (2) morphometric measurements and mercury (Hg) concentrations, and a folder of individual photographs of captured lake trout. Lake trout were collected between September of 2020 and August of 2023 from...

This data release contains data used within the PRMS CONUS Futures Portal including descriptions of data layers in the Uncertainty Analysis section, reference model performance at stream gage locations, and model performance metrics for climate model based simulations. 1) The description of variables available in the Uncertainty Analysis tab include variable short name, variable long...

A collaborative effort with US Fish and Wildlife Services is underway with the goal of reducing the spread of flea contracted plague in prairie dog (Cynomys spp.) colonies across the US. One method of flea reduction being studied involves spreading bait pellets containing insecticides commonly used for flea control around prairie dog habitats. To better understand the effectiveness of...

This data release contains the spatial raster outputs, R code, and lookup table from a synthesis of U.S. Forest Service Activity Tracking System (FACTS) vegetation management activities hypothesized to influence bat habitat. The included raster data cover the continental United States and represent the number of years that have passed since a given management action was implemented...
