Modeled Pacific salmon escapement biomass and nutrient and contaminant concentrations across western North America, 1976-2015 (version 2.0, October 2024) Modeled Pacific salmon escapement biomass and nutrient and contaminant concentrations across western North America, 1976-2015 (version 2.0, October 2024)
The data contain yearly modeled estimates of Pacific salmon escapement (in annual metric tons of wet mass) from 1976 to 2015 across four regions of western North America. A second data file contains modeled estimates of contaminant or nutrient concentrations in Pacific Salmon. The modeled estimates were derived from Bayesian generalized linear models (contaminant or nutrient...
Individual assignments and microsatellite genotypes for Atlantic Sturgeon from 2021 (ver. 4.0, September 2025) Individual assignments and microsatellite genotypes for Atlantic Sturgeon from 2021 (ver. 4.0, September 2025)
This dataset includes genotypes and individual-based assignment tests for 1394 Atlantic Sturgeon selected for assignment by the National Marine Fisheries Service to meet management requirements under the Endangered Species Act.
Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023 Bathymetric and Topographic Surveys at Select Alaska Highway Bridges, 2023
In July 2023, the U.S. Geological Survey Alaska Science Center (USGS ASC) and the USGS Idaho Water Science Center (IDWSC), in cooperation with Alaska Department of Transportation and Public Facilities (AKDOT & PF), completed bathymetric and topographic surveys at four highway bridge structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR). The National...
DSWE_GEE v1.0.0 DSWE_GEE v1.0.0
Code for implementation of the Dynamic Surface Water Extent algorithm in Google Earth Engine. Multiple scripts allow the creation of single-scene or composited Dynamic Surface Water Extent (DSWE) images from Landsat and MODIS data. All code is written for use in the JavaScript API.
High-resolution seismic imaging data acquired in 2021 across a trace of the San Andreas Fault at Mee Ranch, Monterey County, California High-resolution seismic imaging data acquired in 2021 across a trace of the San Andreas Fault at Mee Ranch, Monterey County, California
In April of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Mee Ranch in Monterey County, California. Both passive- and active-source seismic data were acquired using DTCC SmartSolo 3-component nodal seismograph systems ("nodes"), which continuously recorded data at rates up to 2000 samples per second. For passive-source acquisition, a 6x5 grid of nodes was...
High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California High-resolution seismic imaging data acquired in 2021 across the West Winters Fault, Great Valley Fault System at Bigelow Hills, Yolo County, California
In June of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Winters, California. Seismic data were acquired using a DTCC SmartSolo 3-component nodal seismograph system ("node"), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart from west-southwest to east-northeast to create an approximately 800-m-long linear profile...
