This dataset includes GPS locations of free-roaming donkeys (Equus asinus; also called burros) in southern California, USA, within Fort Irwin National Training Center and Death Valley National Park between 2020 and 2022, as well as data on the disease status of donkeys in these same areas. Data were collected by placing GPS collars on donkeys and tracking their movements. Collars...

Rocks were collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 aboard the R/V Thomas G. Thompson. Rocks were subsampled into Bulk and Rind samples at USGS and then sent to Activation Laboratories and Intertek for major and trace element geochemistry analysis.

We conducted a study to evaluate the movements and habitat use of juvenile salmonids, including Chinook salmon, in the lower Columbia River Estuary near dredge spoil deposition sites. Fish tagged with JSATS 416.7 kHz acoustic transmitters for upriver dam passage and survival studies were monitored using strategically placed hydrophones throughout the navigation channel, Woody Island...

Ceratomyxosis, characterized by enteritis, enteronecrosis,and abdominal distension, is caused by the myxozoan parasite Ceratonova shasta. Ceratonova shasta is capable of infecting a range of salmonids, including Chinook salmon, often resulting in increased morbidity and mortality in infected populations. Ceratonova shasta is endemic in the Pacific Northwest, however there is limited data...

We conducted a study to examine the use of off-channel and dredge spoil habitats by migrating juvenile salmonids in the Columbia River Estuary. In addition to the equipment deployed to detect transmitters implanted in juvenile salmonids for this study, a subset of the deployed gear included 69 kHz acoustic telemetry receivers. These receivers opportunistically monitored movements of...

This dataset contains the Mann-Kendall p value, Theil - Sen slope estimate, summary statistics for eleven modelled water budget components simulated by the following modeling applications: the National Hydrologic Model Precipitation-Runoff Modeling System (NHM-PRMS) version 1.1 (Markstrom and others, 2024), the Weather Research and Forecasting hydrological modeling application (WRF-Hydro

This data set includes information on macroinvertebrate community composition collected along with benthic algae and dreissenid mussels from May to October of 2024. Stations are located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. Macroinvertebrates were identified from benthic samples collected by scuba divers. Macroinvertebrates, algae, and dreissenids were...

These digital elevation models of difference (DEMs of Difference, or DoDs) display topographic change from the targeted stream channel at a controlled watershed #4 and study watershed #1 within the larger Los Planes Watershed.The DoDs are computed from a very-high resolution drone DEM surveyed in 2024 and aerial lidar DEM from 2021.Several processing steps were taken to align DEMs and...

The dataset includes processing scripts and 42 raster files of predicted change (delta) in annual vegetation phenology under future climate scenarios in the U.S. Southwest, using different combinations of phenology metrics, time periods, and emissions scenarios. Delta values are median projected changes across 10 global climate models and are relative to a reference period of 1981-2010

We assessed the performance of the real-time quaking-induced conversion (RT-QuIC) assay under different soil textures. We combined sand, silt and clay in different proportions to create experimental soils representative of southwest Wisconsin, USA. Experimental soils were spiked with a brain homogenate from a chronic wasting disease positive white-tailed deer (to test assay sensitivity)...

This is the primary repository for Geodetic Centroid (gCent) Catalog earthquake information, interferograms, and pixel tracking maps. This repository will be updated with new events as time permits and may not reflect the most up to date composition of the gCent catalog. Results included in this catalog, such as ShakeMap polygons, may differ from the operational products used and...

This data release provides access to magnetics data collected by the AUV Sentry during the TN403 cruise in the Escanaba Trough (USGS Field Activity 2022-621-FA).
