U.S.-Mexico Borderland & vegetation community map U.S.-Mexico Borderland & vegetation community map
People on both sides of the United States-Mexico border need a high-resolution, binational vegetation community map that spans the entire United States-Mexico borderlands. Traditionally, mapping efforts in this region were impeded by complex logistics related to the international border, differing national needs and plans, and resource allocations and priorities. To address this need...

Advancing subsurface investigations beyond the borehole with passive seismic horizontal-to-vertical spectral ratio and electromagnetic geophysical methods at transportation infrastructure sites in New Hampshire Advancing subsurface investigations beyond the borehole with passive seismic horizontal-to-vertical spectral ratio and electromagnetic geophysical methods at transportation infrastructure sites in New Hampshire
The U.S. Geological Survey (USGS), in cooperation with the New Hampshire Department of Transportation (NHDOT), surveyed transportation infrastructure sites using rapidly deployable geophysical methods to assess benefits added to a comprehensive site characterization with traditional geotechnical techniques. Horizontal-to-vertical spectral-ratio (HVSR) passive-seismic and electromagnetic...

Connecting flood-related fluvial erosion and deposition with vulnerable downstream road-stream crossings Connecting flood-related fluvial erosion and deposition with vulnerable downstream road-stream crossings
Fluvial erosion is increasingly responsible for infrastructure and building damages associated with floods as the intensity of extreme rainfalls hit rural and urban rivers in a variety of climate settings across the United States. Extreme floods in 2016 and 2018 caused widespread culvert blockages and road failures, including extensive damage along steep tributaries and ravines in the...

Bedform distributions and dynamics in a large, channelized river: Implications for benthic ecological processes Bedform distributions and dynamics in a large, channelized river: Implications for benthic ecological processes
Sand bedforms are fundamental habitat elements for benthic fish in large, sand-bedded rivers and are hypothesized to provide flow refugia, food transport, and ecological disturbance. We explored bedform distributions and dynamics in the Lower Missouri River, Missouri, with the objective of understanding the implications of these features for benthic fish habitat, particularly for the...

Novel use of antifungal nail lacquer to treat candida bill infections in ducks Novel use of antifungal nail lacquer to treat candida bill infections in ducks
Captive wild ducks in the research colony at the USGS Eastern Ecological Science Center, Laurel, Maryland USA frequently contract Candida infections on the upper and lower bills. Various standard treatments were attempted with mixed success. Several of the Surf Scoters, especially, suffered extreme erosions of the bill leading to euthanasia prior to using this new treatment. For the past...

Assessment of a new GeoAI foundation model for floodinundation mapping Assessment of a new GeoAI foundation model for floodinundation mapping
Vision foundation models are a new frontier in GeoAI research because of their potential to enable powerful image analysis by analyzing and extracting important image features from vast amounts of geospatial data. This paper evaluates the performance of the first-of-its-kind geospatial foundation model, IBM-NASA’s Prithvi, to support a crucial geospatial analysis task: flood inundation...

Hidden system identification: Basin modeling as a tool for examining sedimentary geothermal resource potential Hidden system identification: Basin modeling as a tool for examining sedimentary geothermal resource potential
Three-dimensional (3D) geologic and temperature models have been developed for the onshore U.S. Gulf Coast. The results from these models identify areas of moderate- to high-temperature (90°-150°C and >150°C; respectively) geothermal resources at depths
