To address how phytoplankton in the Great Lakes respond to macro- and micronutrients, we conducted a bottle incubation enrichment experiment using water collected from blooming (Maumee Bay and Fox River) and non-blooming sites (Detroit River and Ford River) in Lakes Erie and Michigan, respectively, during late summer. Surface water from these locations was collected and taken to Kent...

Sonic velocity and density well logs in the Eel River area in northern California (Ferndale north Arcata) were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website (https://maps.conservation.ca.gov/doggr/wellfinder/). The data consist of transit times and bulk density measured downhole in...

Acoustic telemetry data (Innovasea, Inc.) were collected on invasive Silver Carp (Hypophthalmichthys molitrix) in the lower reaches of the Tennessee and Cumberland river systems to determine timing and environmental conditions associated with dam passages by Silver Carp during 2016–2019. Data also include water level. dam discharge, and lock use data for three dams within these river...

This dataset contains the accumulated stream survey data collected to identify climate impacts to fish communities and assess stream restoration as a potential climate-change mitigation action across the Great Plains and High Desert of Wyoming and Montana (2021-2024). We also provide data of incidental observations of amphibians, reptiles, crayfishes, and mussels seen while conducting...

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...
