Fish Data Collection on the Canadian River 1995-2015

The use of streamflow simulations from the Vflo model and subsequent calculation of streamflow metrics to investigate flow-ecology relationships may be hindered by our inability to accurately model flow variability and extreme flows of the arid Great Plains. The Canadian River and other rivers in the Great Plains tend to have highly variable flows and harsh environmental conditions. The combination of these environmental conditions makes semi-arid and arid regions difficult to represent with a hydrologic model, especially extreme events. In some cases, overestimating flows may be acceptable to water managers (e.g., vulnerability of infrastructures), but could greatly affect estimates of fish species persistence. To address incidences where poor model performance affected metrics derived from Vflo simulations, we suggest three possible options. 1) Restrict flow-ecology relationships to the mainstem of the Canadian River below Lake Meredith, 2) Restrict assessments to streamflow data aggregated at a monthly time step (although typically, this does not match ecological processes well); 3) Focus on streamflow metrics with a high prediction accuracy (e.g., magnitude, timing and duration at some locations). To maximize the number of potential explanatory variables and survey locations available in the Canadian River basin for the development of flow-ecology response models and minimize bias and uncertainty, a combination of these approaches is likely warranted. To move forward on flow-ecology relationships with valid statistical power, the compiled fish data (see processing steps) is best combined with available gage data to improve the development of ecological relationships.

Processed continuous resistivity profile data collected in Northport Harbor on Long Island, New York on May 13, 2008

An investigation of coastal groundwater systems was performed along the north shore of Long Island, New York during May 2008 to constrain nutrient delivery to Northport Harbor and Manhasset Bay by delineating locations of likely groundwater discharge. The embayments are bounded by steep moraines and are underlain by thick fine-grained sediments deposited in proglacial lakes during the last ice age. Beach sand and gravel overlie the glacial deposits along the coast. The continuous resistivity profiling (CRP) surveys that were conducted indicate the existence of low-salinity groundwater in shore-parallel bands, typically 25 to 50 meters wide, along the shorelines of both bays. Piezometer sampling and seepage meter deployments in intertidal and subtidal areas of the two bays confirmed the presence and discharge of brackish and low-salinity groundwater. The large tidal ranges (up to 3 meters), and the steep onshore topography and hydraulic gradients are important variables controlling coastal groundwater discharge in these areas. For more information on the survey involved in this project, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2008-007-FA.

Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: Hydrologic Landscape Regions

This tabular data set represents the percent of Hydrologic Landscape Regions compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data is the "Hydrologic landscape regions of the United States" produced by the United States Geological Survey (Wolock, 2003). Units are percent. The "Hydrologic landscape regions of the United States" are a 20-class classification scheme of noncontiguous regions (HLRs) built on the basis of similarities in land-surface form, geologic texture, and climate characteristics (Wolock, 2003). Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).

Seismically triggered landslides in the area above the San Fernando Valley

This inventory was originally created by Morton (1971) describing the landslides triggered by a sequence of earthquakes, with the largest being the M 6.6 San Fernando, California earthquake that occurred on 9 February 1971 at 14:00:41 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory includes landslides triggered by a sequence of earthquakes rather than a single mainshock. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use.   With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological Survey (USGS) and thus have not been reviewed for accuracy and completeness by the USGS.  They are presented as part of this data series for convenience of the user only, as part of an effort to make published ground-failure inventories more accessible from a single aggregated site. No warranty, expressed or implied, is made regarding the display or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty.

Burn Severity Assessment of the 2021 Horne Fire at Isle Royale National Park

The 2021 Horne Fire on Isle Royale National Park (ISRO) ignited when lightning struck the island near Duncan Bay on August 10, 2021, during elevated drought conditions. Per the National Park Service, it would continue to burn slowly and spread until a wind event on August 21, 2021 caused significant spread and initiated a control effort to protect historical structures in Tobin Harbor. The fire was 75% contained by September 6, 2021, and allowed to smolder until winter rain and snow finally extinguished the fire. The Horne Fire became the third-largest wildfire in the park’s history, necessitating a detailed assessment of landscape responses to spatial variability in burn severity. These data were created by comparing high-resolution imagery from pre- and post-fire conditions to delineate land cover into burn severity classifications. Such analysis aims to inform management strategies in the aftermath of large-scale wildfires.

High-resolution airborne magnetic and radiometric survey of the Republic Graben, Okanogan and Kettle metamorphic core complexes, Kootenay Arc and surrounding regions, Northeastern Washington

The Republic survey consists of high-resolution aeromagnetic and radiometric data designed to image the subsurface geology and structure of a large portion of northeastern Washington. These data are intended for rigorous modeling and interpretation of the geology and structure in this region and will be used to evaluate the potential for undiscovered resources and will contribute to USGS and Washington DNR-related mineral and geothermal resource assessments of the region. This release includes aeromagnetic and aeroradiometric data collected via low-altitude helicopter flown over northeastern Washington State, centered over the town of Republic, Washington. The data were acquired between September 26, 2022 and August 21, 2023 by Precision Geosurveys, Inc. of Langley, British Columbia and processed by EDCON-PRJ, Inc. of Lakewood, Colorado, contracted by the U.S. Geological Survey and funded through the Earth Mapping Resources Initiative (EarthMRI). The survey includes gridded data from target altitude of 80-100 meters above ground level, subject to aircraft climb and descent limitations. Primary transverse flight lines were flown in the east-west direction and spaced 200 meters apart. Tie lines were flown in the north-south direction and spaced 2000 meters apart. Additionally, the survey includes two transect lines flown down the Similkameen and Okanogan Valleys where local topography was too extreme to maintain an ideal drape surface. A total of 94,506 line kilometers of data were collected over an area of 16,885 square kilometers. Survey procedures are described in detail in the document “WA Republic Mag RAD D22 Project Report_report.pdf” available in this data release. The Republic aeromagnetic and aeroradiometric survey was collected over steep and highly variable terrain, thus the terrain clearance should be considered carefully when modeling and interpreting magnetic and radiometric data. This data release includes .csv file databases for the main survey and transect data collections, derivative magnetic and radiometric data in map view in .grd and .tiff file format, and shapefiles of the transect lines along the Similkameen and Okanogan Valleys.

3D Geologic Framework for use with the U.S. Geological Survey National Crustal Model for Seismic Hazard Studies (ver. 2.0, September 2025)

A three-dimensional (3D) geologic framework of the conterminous United States is presented here as part of the U.S. Geological Survey National Crustal Model for Seismic Hazard Studies. The framework is based on 1:250,000 to 1:1,000,000-scale state and continent-wide geologic maps and depths to multiple subsurface unit boundaries. The geology at or near the Earth’s surface is based on published maps with modifications to remove discontinuities across state and country borders. Extrapolation of rock type and age in the subsurface is achieved by iterative stripping of units of a given age, nearest neighbor interpolation of the remaining units, and constraints on basement geology. The subsurface depth of the interfaces between units is determined by a range of models with varying quantity and quality of constraints. Bedrock depth (assumed to be base of Miocene in many cases) is derived primarily from a proxy model with added geophysical constraint in some areas. The depths to the base of Cenozoic and Phanerozoic sedimentary and extrusive volcanic rocks are constrained by geophysical methods in many areas. Elsewhere, a simple method is used to estimate their subsurface depth based on the distance to the edge of the geologic units constrained by well data. The remaining continental units are evenly distributed above, below, and between depending on age. The oceanic crust is treated as a simpler four-layer model with the added complexity of subduction beneath the North American plate along the Cascadia subduction zone. Refinements to this technique can be accomplished in future versions of the model with more specific information including the location of faults to produce discontinuities in geologic structure and additional information obtained from boreholes and geophysical studies. Further improvements to the geologic framework can be made by incorporating information from more local studies, for example, hydrogeologic studies. The 3D Geologic Framework for use with the U.S. Geological Survey National Crustal Model is provided in this data release as multiple linked netcdf files that describe the spatial grid of the model, a series of stacked elevation surfaces, and attributes of rock type and age within the volume of the Geologic Framework. The netcdf files in this data release contain geologic profiles at locations on a 1-km grid across the conterminous United States. Data structure and use of the netcdf files are described in the README file that is part of this release. This data release updates the geologic framework of the National Crustal Model that was initially released in 2019 and updated in 2020. A version history of updates to the framework model is provided in a text file.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2016 and 2018 Site 0061 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of five land-water products (2005, 2008, 2012, YYYY and 2018).  The resulting matrix has 32 possible classes defined by the combination of land and water categories on those five dates.

Floodplain Forest Canopy Gap Survey Centroid for select gaps in pools of the Upper Mississippi River

These data are a component of a floodplain forest canopy gap dynamics study initiated in 2019 and funded through the US Army Corps of Engineers Upper Mississippi River Restoration, Science Supporting Restoration program. The study included two components: a geospatial component to utilize lidar to identify and map canopy gaps across multiple navigation pools (8, 9, 13, 21, 24, 26 (through Maple Island just south of Lock and Dam 26), and the lower 32 miles of the Illinois River from its confluence with the Mississippi River to Kampsville, IL) within the Upper Mississippi River floodplain and a field component to characterize vegetation in a small subset of the remotely sensed gaps. This layer provides field-collected centroids for the subset of gaps that were selected for field surveys in 2020. Gaps were selected based on a randomly stratified sample of the LiDAR derived gaps, with stratification occurring based on gap size (small (0.0406-0.1012 ha), medium (0.1013-0.3035 ha), large (0.3036-0.8093 ha)) and annual days of flooding within the gap (low (0.1-20 days), moderate (20.1 - 40 days), high (40.1 - 100 days)). The objective of the field study was to determine whether gaps over varying sizes and flood regimes showed variation in vegetation dynamics within the gaps. The geospatial data and scripts used for initial gap identification are available at: https://doi.org/10.5066/P9BLTSTZ. Floodplain inundation rasters that were used to derive the annual inundation rates are available at: https://doi.org/10.5066/F7VD6XRT.

Modified soil adjusted vegetation index of the Sarcobatus Flat area of the Death Valley

The raster-based Modified Soil Adjusted Vegetation Index was
derived from Landsat Thematic Mapper imagery data acquired
during June 1989 for Sarcobatus Flat.  The index has been
shown to increase the dynamic range of the vegetation signal
while further minimizing the soil background influences,
resulting in greater vegetation sensitivity as defined by
a "vegetation signal" to "soil noise" ratio.  The data
set was used in determining phreatophyte boundaries for
a ground-water evapotranspiration study and relative
differences in vegetation density between discharge areas.
