To advance the USGS 3D National Topography Model (3DNTM) including the next generation of the 3D Elevation Program (3DEP) and the 3D Hydrography Program, USGS is producing a new one-meter resolution seamless digital elevation model (DEM) product. The project is funded by the Inflation Reduction Act. This dataset is a 1-m seamless DEM prototype that was created from several different 3D Elevation Program (3DEP) Original Product Resolution source DEMs. The DEM covers the spatial extent of the Lower Androscoggin River Watershed 8-digit hydrologic unit (01040002), as delineated in the USGS Watershed Boundary Dataset. This prototype data is being released as a precursor to the new product that will be seamless across...

This data release includes field spectra collected from a boat during a tracer experiment performed on the Missouri River near Lexington, Missouri, on May 11, 2024. One of the primary goals of this study was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) in a large, highly turbid natural river channel using data from a Uncrewed Aircraft Systems (UAS)-based hyperspectral imaging system. Previous research on remote sensing of tracer dye concentrations demonstrated the ability to obtain moderately precise concentration estimates from standard red-green-blue (RGB) video and orthophotos and this experiment allowed us to evaluate the hypothesis that more detailed spectral information...

This dataset consists of 2-dimensional (2D) XBeach model input files used for Coastal Storm Modeling System (CoSMoS) tier 3 simulations. These sub-regional simulations cover portions of the Northern California open-coast region; boundary conditions are derived from sub-regional tier 2 simulations. These simulations are run for several storm events (covering a range of no storm, 1-year, 20-year, and 100-year coastal storm conditions) and sea-level rise (SLR) scenarios.

In 2012, Hurricane Sandy struck the Northeastern US causing devastation among coastal ecosystems. Post-hurricane marsh restoration efforts have included sediment deposition, planting of vegetation, and restoring tidal hydrology. The work presented here is part of a larger project funded by the National Fish and Wildlife Foundation (NFWF) to monitor the post-restoration ecological resilience of coastal ecosystems in the wake of Hurricane Sandy. The U.S. Geological Survey Woods Hole Coastal and Marine Science Center made in-situ observations during 2018-2019 and 2022-2023 at two sites: Thompsons Beach, NJ and Stone Harbor, NJ. Marsh creek hydrodynamics and water quality including currents, waves, water levels, water...

Environmental Sensitivity Index (ESI) maps provide a concise summary of coastal resources that are at risk if an oil or chemical spill occurs nearby. Examples of at-risk resources include biological resources (such as shorebirds and mussel beds), sensitive shorelines (such as marshes and coastal wetlands), and human-use resources (such as public beaches and parks, as well as areas that could be used for access and staging in a spill response). Environmental Sensitivity Index maps are used by incident response managers from a wide range of federal and state agencies to guide decisions about where and how to prioritize emergency response and restoration activities after an oil or chemical spill. The National Oceanic...

Climate change threatens plants and animals across the US, making it important to have tools that can efficiently assess species’ vulnerabilities. In this project, CASC scientists and NatureServe are collaborating to update a popular Climate Change Vulnerability Index to include the latest scientific data, improved metrics, and new user-friendly technology. The tool will help state biologists and scientists prioritize conservation efforts, and in time for preparing updates to State Wildlife Action Plans that are due by 2025. Climate change is impacting our nation’s plants and animals. To take preventative actions, public land managers need to know which species are most threatened, and how. In other words, biologists...

Recent catastrophic droughts and wildfires have killed almost 20% of mature giant sequoia trees across California, and it is uncertain whether natural seedling regeneration will be enough to restore these forests, especially in severely burned areas. Researchers supported by this Southwest CASC project will assess whether soil conditions, such as moisture and soil microbial communities can increase sequoia seedling survival. Findings from this project will help land managers identify the most effective replanting strategies and determine which areas are more or less likely to support successful sequoia seedling regeneration. Ancient groves of giant sequoia trees inspire people all over the world. Recently, however,...

This study examines potential drivers of American kestrel (*Falco sparverius*; hereafter kestrel) population declines in North America and uses decision analysis to formally identify future research priorities that are most likely to result in corrective management actions. The study objectives are to (1) develop a continental-scale integrated population model to quantify the relative influence of survival and fecundity on population trends, (2) generate hypotheses relevant to causes of kestrel population declines and prioritize future monitoring and research activities as well as conservation actions, and (3) develop regional-scale models to test how specific drivers of decline may vary across the kestrel’s US...

This data release includes digital orthophotos acquired during a tracer experiment performed on the Missouri River near Lexington, Missouri, on May 11, 2024. The orthophotos were acquired from a fixed-wing crewed aircraft and are provided as background images. One of the primary goals of this study was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) in a large, highly turbid natural river channel using data from a Uncrewed Aircraft Systems (UAS)-based hyperspectral imaging system. Previous research on remote sensing of tracer dye concentrations demonstrated the ability to obtain moderately precise concentration estimates from standard red-green-blue (RGB) video and orthophotos...
