Donkey location data and disease exposure data in southern California between 2020 and 2022 Donkey location data and disease exposure data in southern California between 2020 and 2022
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...
Geochemistry and x-ray diffraction data of rock samples from the Escanaba Trough (Gorda Ridge) Geochemistry and x-ray diffraction data of rock samples from the Escanaba Trough (Gorda Ridge)
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.
Juvenile Salmon Outmigration JSATS Telemetry Detections in the Columbia River Estuary Juvenile Salmon Outmigration JSATS Telemetry Detections in the Columbia River Estuary
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...
Field surveillance and sentinel exposures to detect Ceratonova shasta in Chinook Salmon from the Lake Washington watershed Field surveillance and sentinel exposures to detect Ceratonova shasta in Chinook Salmon from the Lake Washington watershed
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...
2025 Columbia River Estuary 69 kHz Telemetry Detections 2025 Columbia River Estuary 69 kHz Telemetry Detections
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...
Monotonic Trends in Modelled Water Supply for Select Outputs from NHM-PRMS, WRF-Hydro, and CONUS404-BA, 1983-2021 and 2000-2020 Monotonic Trends in Modelled Water Supply for Select Outputs from NHM-PRMS, WRF-Hydro, and CONUS404-BA, 1983-2021 and 2000-2020
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
