Data

This data release includes outputs that were created using Monte Carlo simulations with the aim to reduce elevation overestimation in coastal wetlands at Grand Bay, MS. We evaluated the performance of coastal wetland elevation refinement by using bare earth digital elevation models (DEMs) and DEMs created from the last return from the light detection and ranging (lidar) point cloud...

These data are outputs from a mallard (Anas platyrhynchos) reproduction model that accounts for breeding ground arrival time and the body mass of individuals. Specifically, adult female mallards that arrive late or with lower body mass have the potential for lower clutch sizes and are less likely to renest if a nest fails. The model is based on an existing mallard reproduction model that...

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazard, and erosion and sedimentation pattern. These are generated using a suite of numerical models driven by outputs from...

Three studies were conducted in Shasta Reservoir in California to evaluate downstream migration and behavior of juvenile late-fall run Chinook salmon (Oncorhynchus tshawutscha) released in the McCloud River upstream of Shasta Dam in Spring 2017, Fall 2017, and Fall 2024. The goal of this study was to collect data beneficial for citing a juvenile salmon collection system for downstream...

Ecological restoration is essential to meet global biodiversity conservation goals. Given limited conservation budgets, deciding where to restore habitat is a key challenge for the coming decade. This dataset includes optimal restoration sites selected from multiple restoration model scenarios. We developed a modeling approach to maximize conservation benefit/restoration cost ratios to...

The LANDFIRE (LF) 2001 (version 1.0.5) Refresh of the LF National Base Map enhanced the layers of the LF National data set to provide a foundation upon which to build an updated geospatial data set. The enhancements were developed to facilitate comparative analyses, evaluate trends, and potentially monitor changes over time. In particular, LF 2001 enhancements addressed: incomplete data...

Land applied waste byproducts were collected by USGS from 34 sites across the United States. Materials included waste byproducts from treatment of municipal sewage (biosolids), production of food (bovine, poultry, and swine wastes), and drilling of oil and gas wells (spent oil- and water-based drilling fluids). The samples represent 10 municipal wastewater treatment plants, 11 animal...

This model archive summary (MAS) and associated model calibration data contains two model evaluations: 1) a model validation of the prior-published sediment surrogate model at this site for WY 2019-2023, and 2) a new log-transformed turbidity-suspended sediment (SSC) regression model computing SSC from 01/17/2024 to 2/27/2025 following the drawdown of the John C. Boyle reservoir and...

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor...

The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Energy and Environmental Protection and the Connecticut Department of Transportation, compiled a series of raster datasets for use by the USGS StreamStats application for the State of Connecticut and adjacent states. The raster datasets were used to compute basin characteristics that were used in...

Rock physical property measurements were collected on core samples to help understand the causative sources of gravity and magnetic survey anomalies in northwestern Minnesota. A total of 410 measurements of magnetic susceptibility and density on Archean core samples from 20 boreholes have been conducted. The measurements aid in interpretation of gravity and airborne magnetic data that...
