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...
Time-series measurements of oceanographic and seabed response data collected in Cape Cod Bay, Barnstable, MA, March 10 to April 7, 2021 Time-series measurements of oceanographic and seabed response data collected in Cape Cod Bay, Barnstable, MA, March 10 to April 7, 2021
To assess cross-shore sediment transport prediction techniques in coastal models for a wave-dominated sandy coast, the U.S. Geological Survey Woods Hole Coastal and Marine Science Center collected data to measure wave-induced and mean current water velocities near the seabed and the response of the seabed to these forces. A four-legged bottom landing frame (quadpod) containing...
Merged topography and bathymetry, Glacier Bay and Icy Strait, Alaska Merged topography and bathymetry, Glacier Bay and Icy Strait, Alaska
This work integrated multiple topographic and bathymetric data sources to generate a merged topobathymetric map of Glacier Bay, Alaska (AK) and vicinity, including Icy Strait and parts of Lynn Canal. Earlier topobathymetric sources covering the Glacier Bay region were originally developed by the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental...
