Observation Data of Migratory Birds during Spring and Fall Migration and their use of Habitats in the Yakutat Foreland of Alaska Observation Data of Migratory Birds during Spring and Fall Migration and their use of Habitats in the Yakutat Foreland of Alaska
This data package presents raw legacy data collected during 1980 on the Yakutat Forelands of southeast Alaska. The data were collected to identify and understand the occurrence and distribution of birds and mammals in the ocean and wetlands near Yakutat. Migration "sea watches", aerial surveys, and ground plot surveys were conducted in the foreland area of Yakutat in spring (April - May)...
Airborne magnetic and radiometric survey, Munsungun region in northern Maine, 2021 Airborne magnetic and radiometric survey, Munsungun region in northern Maine, 2021
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of northern Maine. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding volcanogenic massive sulfide mineral deposits, sediment hosted manganese deposits, and...
Digital database of the previously published Geologic Map of the Lamar Quadrangle, Colorado and Kansas Digital database of the previously published Geologic Map of the Lamar Quadrangle, Colorado and Kansas
This digital data release contains geospatial geologic data compiled for the Lamar 250k quadrangle, a region in eastern Colorado and western Kansas, which is predominantly covered by Quaternary deposits that overlay Cretaceous bedrock. Geologic data, compiled from published sources, include the location and characteristics of geologic contacts and faults, mapped geologic polygons, and...
S-NPP 375-m eVIIRS Remote Sensing Phenology Metrics - across the conterminous U.S. (ver. 3.0, August 2025) S-NPP 375-m eVIIRS Remote Sensing Phenology Metrics - across the conterminous U.S. (ver. 3.0, August 2025)
Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. Researchers at the U.S. Geological Survey (USGS), Earth Resources Observation and Science (EROS) Center have developed methods for documenting the seasonal dynamics of vegetation in an operational...
Spatially-Explicit Predictive Maps of Greater Sage-Grouse Brood Selection Integrated with Brood Survival in Nevada and Northeastern California, USA Spatially-Explicit Predictive Maps of Greater Sage-Grouse Brood Selection Integrated with Brood Survival in Nevada and Northeastern California, USA
We used a hierarchical Bayesian modeling framework to estimate resource selection functions and survival for early and late brood-rearing stages of sage-grouse in relation to a broad suite of habitat characteristics evaluated at multiple spatial scales within the Great Basin from 2009 to 2019. Sage-grouse selected for greater perennial grass cover, higher relative elevations, and areas...
Ecological Data Mapper Ecological Data Mapper
This application was created to visualize and interact with the ecological data from the ongoing monitoring effort on two previously restored streams in Reston, Virginia - Snakeden Branch and The Glade. The “Reston monitoring program” includes the measurement of hydrologic, water-quality, and ecological data and evaluations of changes in these measurements over time. For more information...
