Salinity levels in streams and tributaries of the Colorado River Basin have been a major concern for years. Recently, the United States Geological Survey’s (USGS) Next Generation Water Observing System (NGWOS) program expanded stream monitoring networks including the number of sites where continuous (15-minute) specific conductance is measured in the Colorado River Headwaters and...

This release contains data collected to study surface-groundwater interactions during flood events in the floodplain of a restored reach of Underwood Creek in Wauwatosa, WI. Continuous floodplain sediment temperature data was collected at 6 sites from May 2018 to October 2021. Temperature data was used in conjunction with soil thermal property measurements and published groundwater...

This dataset consists of Structure-from-Motion derived point clouds and detailed orthomosaic images of four exposures covering the Williamsport Sandstone and the Bloomsburg Formation in eastern West Virginia and south-central Pennsylvania. For each roadcut exposure, two datasets are published: an orthomosaic raster image and a point cloud. The orthomosaic raster image is a vertical...

This dataset consists of Structure-from-Motion (SfM) - derived point clouds and highly detailed orthomosaic images of two exposures covering the the Rose Hill Formation, Keefer Sandstone, McKenzie Formation, Williamsport Sandstone, Bloomsburg Formation, Tonoloway Limestone, and the Keyser Limestone. For each railway exposure, two datasets are published: an orthomosaic raster image and a...

The products provided here include four georectified mosaics of historic aerial photographs for the Parker Valley region within western Arizona and southeastern California. There are three individual mosaics from 1930, 1938, and 1947 covering different geographic areas. The fourth georectified mosaic is a composite of the three and covers the entire area of interest. These datasets were...

This data release includes the results (and some input data) of a spatial conservation prioritization intended to guide management of sagebrush ecosystems in northwest Colorado. Stemming the loss and degradation of sagebrush ecosystems requires science-based tools to balance diverse habitat requirements of species and guide management actions to where they are most likely to successfully...

While the timing and composition of the Yellowstone Plateau volcanic field’s caldera-forming tuffs and rhyolite flows are well-characterized, the chronology of smaller-volume mafic eruptions is poorly known, thereby limiting our understanding of how mafic magmatism drives rhyolite volcanism, particularly Yellowstone’s large caldera-forming eruptions. To address this gap in knowledge, we...

This dataset includes rock magnetic susceptibility and gamma ray spectrometer measurements from 243 outcrops in southwest Montana during 2023-2024. The measurements were collected to understand the causative sources of airborne magnetic and radiometric survey anomalies in the Idaho-Montana porphyry belt. Sixteen magnetic susceptibility measurements were collected at each analyzed site...

Porphyry copper deposits are the world's primary source of copper and can also host a variety of secondary commodities identified as critical by the U.S. Geological Survey (U.S. Geological Survey, 2022). These deposits occur primarily along convergent plate margins, and their metal association and geochemical characteristics are reflective of whether the deposit formed in continental...

This data publication contains information collected as part of a field and laboratory effort to determine prevalence of avian malaria (Plasmodium relictum) and pox-like lesions (Avipoxvirus spp.) in native and non-native forest birds on the northern, high elevation (>1500 m) slopes of Haleakala volcano on Maui during the last decade of the 20th century. Forest bird banding data and...

At least 28 rhyolitic lava flows, domes, and tuffs erupted within Yellowstone caldera following its formation 631 ka. Understanding the timing of intracaldera eruptions is essential for characterizing natural hazards posed by Yellowstone volcano. We present 40Ar/39Ar eruption ages for the Mallard Lake Member and Central Plateau Member of the Plateau Rhyolite, which comprise products from...

Data collected to facilitate research and development activities pertaining to Annual NLCD algorithm development used as a benchmark for algorithm improvement iterations. The primary goal of these preliminary data was to offer preliminary insight into algorithm performance and guidance for algorithm improvement through error analysis.
