LANDFIRE 2001 Base Map LANDFIRE 2001 Base Map
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...
USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States
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...
Model Archive Summary for Suspended Sediment Concentration at station 11510700, Klamath River below John C. Boyle Powerplant, near Keno, OR, October 2023 to February 2025 Model Archive Summary for Suspended Sediment Concentration at station 11510700, Klamath River below John C. Boyle Powerplant, near Keno, OR, October 2023 to February 2025
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-quality, bed-sediment, and invertebrate tissue trace-element data for the Clark Fork and tributaries in the upper Clark Fork Basin, Montana, October 2021-September 2022 Water-quality, bed-sediment, and invertebrate tissue trace-element data for the Clark Fork and tributaries in the upper Clark Fork Basin, Montana, October 2021-September 2022
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...
Basin Characteristics for Development of Regression Equations to Estimate Flow Durations, Low-Flow Frequencies, and Mean Flows in Connecticut through Water Year 2022 Basin Characteristics for Development of Regression Equations to Estimate Flow Durations, Low-Flow Frequencies, and Mean Flows in Connecticut through Water Year 2022
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...
Density and magnetic susceptibility measurements on Archean rocks, northwestern Minnesota, 2021 Density and magnetic susceptibility measurements on Archean rocks, northwestern Minnesota, 2021
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...
