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.

AquaMatch Chlorophyll a Data from Water Quality Portal: ~1970-2024 AquaMatch Chlorophyll a Data from Water Quality Portal: ~1970-2024
This dataset, “AquaMatch Chlorophyll a Data from Water Quality Portal ~1970-2024”, is a component of a forthcoming update to AquaSat (Ross et al., 2019), AquaSat version 2 (“v2”). The overarching purpose of AquaSat V2 is to emphasize the individual parts of the AquaSat pipeline that make-up the matchups between satellite and in-situ measurements.
Data and analytical code associated with pinyon jay local-scale density-habitat relationship model (2008 - 2020) in the InterMountain West, USA Data and analytical code associated with pinyon jay local-scale density-habitat relationship model (2008 - 2020) in the InterMountain West, USA
This data release provides pinyon jay (Gymnorhinus cyanocephalus) counts and local-scale vegetation data associated with summertime point count surveys conducted throughout the InterMountain West under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program, 2008 - 2020. We also provide code written in the R programming language to model pinyon jay abundance as a function...
Multilayer perceptron classifier and shoreline extraction routine for Minnesota Point PlanetScope satellite imagery Multilayer perceptron classifier and shoreline extraction routine for Minnesota Point PlanetScope satellite imagery
A site-specific multilayer perceptron model was developed to classify PlanetScope satellite imagery of Minnesota Point, and the classifier was paired with a shoreline delineation routine to extract the position of the land-water interface. Satellite-dervived shorelines were used to measure changes in beach width associated with beach nourishment projects and changing water levels. The...
Data release for toxicity of Antimycin A incorporated management bait for grass carp Data release for toxicity of Antimycin A incorporated management bait for grass carp
The goal of this study was to develop and examine whether a management bait that can be used for selective control of grass carp. Our objectives were to 1) quantify the water-based 24-h LC50 of Antimycin-A for grass carp and rainbow trout, 2) quantify the 96-h LD50 of orally administered Antimycin-A laden bait for grass carp and rainbow trout, 3) quantify the leaching rate of Antimycin-A...
SWAT Model Archive for Simulation of Hydrology, Suspended Sediment and Nutrients in Selected Tributary Watersheds of Lake Erie, New York SWAT Model Archive for Simulation of Hydrology, Suspended Sediment and Nutrients in Selected Tributary Watersheds of Lake Erie, New York
This U.S. Geological Survey (USGS) data release contains model scenario input and output files and nine hydrology and water-quality models developed using the Soil and Water Assessment Tool (SWAT). The models represent nine watersheds in eastern New York that drain to Lake Erie or the Niagara River and were created, calibrated, and validated for hydrology, sediment, and nutrients as...
Surficial geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado Surficial geologic map database for the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado
This data release presents geologic map data for the surficial geology of the Blanca Peak, Walsenburg, Trinidad, and Alamosa 30' x 60' quadrangles, Colorado, and an adjacent area to the north of the Blanca Peak quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains Province, and the Great Plains Province, Raton Section. Geologic...
