This multi-layer GeoPackage contains the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey design transects from 2007 to present. The original transects were created as shapefiles and imported to this SQLite database. Transects were saved as individual polylines named according to the year they were created (e.g., “main.ACP_2007_Trans,” “main.ACP_2008_Trans,” “main.ACP_2009_Trans,” etc.). These aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. The current four-year rotating...

An ASD FieldSpec 4 Hi-Res NG Spectroradiometer was used to collect the reflectance properties of soil and rock in Prince William Sound (Figure 1). Reflectance is a property of the material being observed, being the ratio of the amount of light leaving a target to the amount of light striking the target. Reflectance is a unitless value from 0 to 1, where a value of 0 indicates that the material absorbs all energy and 1 indicates total reflectance. The ASD FieldSpec 4 Hi-Res NG is a point spectrometer that has a spectral range of 350 to 2500 nm, covering the visible and near-infrared (VNIR) and short-wave infrared (SWIR) portions of the electromagnetic spectrum. The spectral resolution is 3 nm at 700 nm and 6 nm at...

The U.S. Geological Survey (USGS) developed models to estimate plant-level thermoelectric water use based on linked heat-and-water budgets to provide a consistent method for water-use estimation across the fleet of U.S. thermoelectric plants. In addition to calculating a thermodynamic “best” estimate for each powerplant, the models also calculate plausible ranges of minimum and maximum withdrawal and consumption. Historically, there have been two federal sources for thermoelectric water use information. The Department of Energy's Energy Information Administration (EIA) publishes annual thermoelectric water withdrawal and consumption data based on plant operator-reported surveys. The USGS has published water-use...

Note: this data release is currently being revised and is temporarily unavailable. An extensive archive, estimated to contain more than 3,500 historical (1925–2020) geophysical logs collected in conjunction with past studies conducted by various entities, and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) located in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 6,058 of these records in Portable Document Format (PDF) along with a public Microsoft Access database and comma-separated values (CSV) text file containing...

Minnesota Geological Survey is working with partners to build a statewide, consistent, standardized, and documented geochemical database, due to the convergence of: 1) systematic sampling & analysis of soils and stream sediments by the USGS & the MGS; 2) completion of a statewide till geochemical survey by MGS in cooperation with industry, and 3) renewed efforts by Minnesota Pollution Control Agency (MPCA) to ensure optimal usability of their state ground-water chemistry data. The soil/sediment data are distributed statewide, were collected over a short period of time, and samples from each project were analyzed by the individual labs following consistent and documented protocols, while the MPCA water analyses were...
