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.

Data Release: Evaluation of Bayluscide 20% suspension concentrate formulation field performance (Indian River, Schoolcraft County, MI) Data Release: Evaluation of Bayluscide 20% suspension concentrate formulation field performance (Indian River, Schoolcraft County, MI)
The sea lamprey, Petromyzon marinus, is a parasitic, invasive fish of the Laurentian Great Lakes. Since the late 1950s, the Great Lakes Fishery Commission has administered a Sea Lamprey Control Program (SLCP) that is executed collaboratively by the United States Fish and Wildlife Service and Fisheries and Oceans Canada. This program relies on two lampricides, TFM (4-nitro-3-...
Waterfowl Census Data during Fall Migration at Nanvak Bay, Togiak National Wildlife Refuge, Alaska, 1992 Waterfowl Census Data during Fall Migration at Nanvak Bay, Togiak National Wildlife Refuge, Alaska, 1992
Waterfowl were observed staging at Nanvak Bay, Togiak National Wildlife Refuge in southwest Alaska between 31 August and 27 September 1992. This data release contains five tables including 1) aerial surveys, 2) band resights for Black Brant (Branta bernicla nigricans), 3) Black Brant age ratios, 4) bird migration observations, and 5) taxonomy table for observed birds.
Field measurements of water depth and remotely sensed data from the Mulchatna River, Alaska, collected July 12-August 14, 2024 Field measurements of water depth and remotely sensed data from the Mulchatna River, Alaska, collected July 12-August 14, 2024
This data release provides field measurements of water depth and aerial and satellite images from the Mulchatna River in Alaska. These data were used to assess the feasibility of mapping the bathymetry of this remote, proglacial river, located in Lake Clark National Park and Preserve, using several depth retrieval algorithms. This approach could facilitate geomorphic and habitat...
MITRE WaterSHEDs PFAS vulnerability model output for Upper Colorado River Basin at 1 km, 9 km, and 100 km hexagonal tessellations MITRE WaterSHEDs PFAS vulnerability model output for Upper Colorado River Basin at 1 km, 9 km, and 100 km hexagonal tessellations
Per- and polyfluoroalkyl substances (PFAS) in the aquatic environment present a water resource management challenge, in part due to the geospatial distribution of presumptive sources and their connections to the hydrological network. MITRE developed a geospatial model called Water Sensing and Hydrology for Environmental Decision Support (WaterSHEDS) that assigns stream-vulnerability...
GeoFlight: Airborne magnetic and radiometric surveys of the Salton Trough, Southern California GeoFlight: Airborne magnetic and radiometric surveys of the Salton Trough, Southern California
The U.S. Geological Survey (USGS) and the Department of Energy (DOE) have collaborated to acquire high-resolution airborne magnetic and radiometric data, over the Salton Trough in southern California, to support geologic and geophysical mapping and modeling that will assist geothermal and critical mineral studies. The surveys, referred to as GeoFlight spans an area that contains some of...
Laboratory-based optical measurements for water samples collected from Clear Lake, California Laboratory-based optical measurements for water samples collected from Clear Lake, California
Clear Lake, located within the Coast Range west of California's Central Valley, is the largest natural freshwater lake contained fully within the state. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower region to the southeast (Lower Arm), and the smallest and narrowest region to the east (Oaks Arm). Water quality in Clear Lake is...
