The U.S. Geological Survey (USGS) installed and operated several flood and debris flow warning gages within or downstream from the Spring Creek burn scar, Colorado, U.S.A. The warning gages were operated during several years post fire (2019-21) in cooperation with the Colorado Department of Transportation (CDOT). The USGS warning gages were part of a larger post-wildfire...

A process-driven biogeochemistry model, Wetland Carbon Assessment Tool - DeNitrification-DeComposition model (WCAT-DNDC) was validated and applied to examine the responses of daily net ecosystem exchange (NEE), net primary productivity (NPP), ecosystem respiration (ER), methane (CH4) and nitrous oxide (N2O) emissions in the Lake Maurepas swamp forests under dry (2011), normal (2019), and...

This dataset provides a predictive ecological state map for the Southwest Sandy and Loamy Uplands Ecological Site Group (ESG). We developed a machine learning approach to predict ecological states by training vegetation cover data from three remotely sensed datasets—Rangeland Analysis Platform (RAP), Rangeland Condition Monitoring Assessment and Projection (RCMAP), and Landscape Cover...

Reports of negative interactions between humans and bears in Maryland have increased steadily since the 1990s, requiring substantial investments of time and resources for their management. While managers typically possess a strong understanding of the spatial distribution of current and historical interactions, they lack the quantitative tools necessary to predict where future...

This dataset provides posterior mean predicted rasters of the distribution of trace elements important to vertebrate health (cobalt, copper, iron, manganese, selenium, and zinc) in the soil across the conterminous United States. Rasters were generated using a Bayesian modeling framework implemented in R with the R-INLA framework (Integrated Nested Laplace Approximation) and the...

This data set includes mortality data from acute toxicity tests with aquatic larvae of the mayfly, Neocloeon triangulifer, exposed to sodium chloride. Two separate tests were conducted and fed diatom diets that were either 7-days-old or 13-days-old.

This geospatial dataset compiles, in digital form, geologic and geophysical data for the Portola 30’x 60’ quadrangle, located in the northern Sierra Nevada, California. This geologic map of the Portola 30’x 60’ quadrangle integrates decades of published and unpublished mapping in the northern Sierra Nevada. In conjunction with geophysical data, including more than 1000 new gravity...

A terrain-based map of a large area of Franciscan Complex delineates varied areas of erosionally resistant topography and contrasting subdued topography distinguished using differences in the detailed shapes of individual topographic elements that in these rocks indicate relatively intact rock or mélange. Most of the line work in the map is based on interpretation of small-scale aerial...

A previously unmapped fault forms a low scarp on a terrace along North Meadow Creek, a drainage on the east flank of the Tobacco Root Mountains, in SW Montana. The fault extends ~7.5 km between points where it disappears beneath alluvium of Madison Valley, on the SE, and glacial moraines on the NW. It appears on neither the Geologic Map of Montana nor the Quaternary Fault and Fold...

Data collected to facilitate research and development activities pertaining to Annual NLCD algorithm development used as a benchmark for algorithm improvement iterations. The primary goal of these preliminary data was to offer preliminary insight into algorithm performance and guidance for algorithm improvement through error analysis.

This data release includes relative landslide hazard estimate maps for the southern Appa­lachian Mountains affected by Hurricane Helene (September 26-27, 2024) and the heavy rainfall that preceded it (September 23-26, 2024). The two modeling approaches used were adapted from existing models and were run in early October 2024 using initial precipitation estimates to produce rapid event...

We present a preliminary point inventory of landslides triggered by Hurricane Helene, which impacted southern Appalachia between September 25 and 27, 2024. This inventory is a result of a rapid response mapping effort led by the U.S. Geological Survey’s Landslide Assessments, Situational Awareness, and Event Response Research (LASER) project. LASER collaborated with state surveys and...
