Alaska Fault Trace Mapping, 2021 Alaska Fault Trace Mapping, 2021
This dataset provides a detailed (1:10,000) digital map of fault and fold traces in Alaska, USA based on features identified in the freely available ArcticDEM 3.0. The fault traces represented in this dataset either revise the location and accuracy of known active faults or folds archived in the USGS Quaternary Fault and Fold Database, or represent the surface traces of active structures...
Model Inputs and Outputs for Simulating and Predicting the Effects of Climate and Land-Use Changes on Thermal Springs Recharge: A System-Based Coupled Surface-water and Groundwater Model for Hot Springs National Park, Arkansas Model Inputs and Outputs for Simulating and Predicting the Effects of Climate and Land-Use Changes on Thermal Springs Recharge: A System-Based Coupled Surface-water and Groundwater Model for Hot Springs National Park, Arkansas
This data release contains model input and output files for simulating and predicting thermal spring flows at Hot Springs National Park (HOSP), Hot Springs, Arkansas. A three-dimensional hydrogeologic framework of the Hot Springs anticlinorium beneath Hot Springs National Park was constructed to represent the complex hydrogeology of HOSP and surrounding areas to depths exceeding 9,000...
Grain-Size Analysis Data From Sediment Samples in Support of Oceanographic and Water-Quality Measurements in the Nearshore Zone of Matanzas Inlet, Florida, 2018 Grain-Size Analysis Data From Sediment Samples in Support of Oceanographic and Water-Quality Measurements in the Nearshore Zone of Matanzas Inlet, Florida, 2018
The interactions of waves and currents near an inlet influence sediment and alter sea-floor bedforms, especially during winter storms. As part of the Cross-Shore and Inlets Processes project to improve our understanding of cross-shore processes that control sediment budgets, the U.S. Geological Survey deployed instrumented platforms at two sites near Matanzas Inlet between January 24 and...
The Louisiana Amphibian Monitoring Program from 1997 to 2017: Data The Louisiana Amphibian Monitoring Program from 1997 to 2017: Data
Call observation data from the Louisiana Amphibian Monitoring Program (LAMP). Each route has 10 stops. The routes are in one of 3 Louisiana regions (north, south and Florida parishes). Routes are identified by number and name. Call observations are categorical number 0 (not heard) through 3 (full chorus with overlapping calls). Each route has 10 stops. A full description of data...
Combined results and derivative products of hydrogeologic structure and properties from airborne electromagnetic surveys in the Mississippi Alluvial Plain (ver. 2.0, July 2024) Combined results and derivative products of hydrogeologic structure and properties from airborne electromagnetic surveys in the Mississippi Alluvial Plain (ver. 2.0, July 2024)
Electrical resistivity results from two regional airborne electromagnetic (AEM) surveys (Minsley et al. 2021 and Burton et al. 2021) over the Mississippi Alluvial Plain (MAP) were combined by the U.S. Geological Survey to produce three-dimensional (3D) gridded models and derivative hydrogeologic products. Grids were discretized in the horizontal dimension to align with the 1 kilometer...
Measured sections and paleocurrent data from fluvial deposits of the Upper Cretaceous-Paleogene Raton and Poison Canyon Formations, Raton Basin, Colorado-New Mexico, USA Measured sections and paleocurrent data from fluvial deposits of the Upper Cretaceous-Paleogene Raton and Poison Canyon Formations, Raton Basin, Colorado-New Mexico, USA
This document provides two data sets that characterize outcrops of fluvial deposits of the Upper Cretaceous-Paleogene Raton and Poison Canyon Formations of the Raton Basin of Colorado-New Mexico, USA. First, the dataset includes stratigraphic sections measured through fluvial deposits of the Raton and Poison Canyon Formations (ten unique .tif files), currently exposed in roadside...
WRTDS annual concentrations, loads and statistical trend likelihoods for sites in the Spokane River watershed, water years 1990-2018 WRTDS annual concentrations, loads and statistical trend likelihoods for sites in the Spokane River watershed, water years 1990-2018
A long history of mining and widespread metals contamination in the Spokane River watershed have led to the area's designation as a Superfund site and extensive, ongoing remedial actions. Long-term (water years 1990 to 2018) water-quality data from twelve sites were used to develop Weighted Regressions on Time, Discharge and Season (WRTDS) and WRTDS with Kalman filtering (WRTDS_K) models...
Chemical characterization of water and suspended sediment of the Snake River and Hells Canyon Complex (Idaho, Oregon) (ver. 3.0, November 2023) Chemical characterization of water and suspended sediment of the Snake River and Hells Canyon Complex (Idaho, Oregon) (ver. 3.0, November 2023)
This dataset includes laboratory analyses of surface water samples and sediment trap material collected from (1) locations upstream, downstream, and within the Hells Canyon Complex (Idaho, Oregon) of the Snake River, (2) tributaries of the Snake River, and (3) two reservoirs near Boise, Idaho, from 2014 to 2021. The study area spans approximately 232 river miles of the Snake River and...
WildAgg: an R package to estimate and visualize wildlife aggregation data WildAgg: an R package to estimate and visualize wildlife aggregation data
This package is designed to estimate, summarize, and visualize wildlife aggregation metrics using location information like GPS collar data. The motivation for the development of this package began with two research efforts studying the aggregation and density of elk on the National Elk Refuge, Wyoming (Janousek et al.2021; and Graves et al. 2021). The primary goal of the WildAgg package...
Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18 Geospatial Data for Bridge Scour Countermeasure Assessments at Select Bridges in the United States, 2016-18
In 2009, the Federal Highway Administration published Hydraulic Engineering Circular No. 23 (HEC-23) to provide specific design and implementation guidelines for bridge scour and stream instability countermeasures. However, the effectiveness of countermeasures implemented over the past decade following those guidelines has not been evaluated. Therefore, in 2013, the U.S. Geological...
