Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

GIS Data for Geologic Map of the Central Pioneer Mountains, Blaine and Custer Counties, Central Idaho GIS Data for Geologic Map of the Central Pioneer Mountains, Blaine and Custer Counties, Central Idaho
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the central Pioneer Mountains, Blaine and Custer counties, central Idaho (Dover, 1983). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS Miscellaneous
Lake Superior Annual Survey Report data: 1978-2025 Lake Superior Annual Survey Report data: 1978-2025
This dataset includes fish community data collected during the annual nearshore and offshore surveys for Lake Superior from 1978-2025. The data includes: the number, weight, number per hectare, and kg per hectare of fish caught at each location from 1978-2025; annual age-1 numerical density estimates for select species in the nearshore region (1978-2025) and offshore region (2011-2025)...
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...
