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.

Body Mass of Dabbling and Diving Ducks Harvested in California Body Mass of Dabbling and Diving Ducks Harvested in California
Body mass data (measured in grams) of dabbling and diving ducks harvested in three regions of California: Sacramento Valley, Suisun Marsh, and San Joaquin Valley during the 2014/2015, 2015/2016, 2016/2017, 2018/2019, and 2019/2020 hunting seasons. In addition to mass, the flattened length of right wing, species, sex, age, and date of harvest were also recorded. These data support the...
Metabarcoding of environmental DNA samples collected below Jackson Lake Dam (Wyoming) and Palisades Reservoir (Idaho) in 2021-2022 (ver. 2.0, November 2024) Metabarcoding of environmental DNA samples collected below Jackson Lake Dam (Wyoming) and Palisades Reservoir (Idaho) in 2021-2022 (ver. 2.0, November 2024)
These metadata contain links to the original sequences on GenBank. These data show the final OTU and metadata tables for each environmental sample collected. Additionally, we included OTU tables resulting from bioinformatic decontamination steps (using microDecon) in R.
Wyoming road age and traffic volume estimated with machine learning and graph theory Wyoming road age and traffic volume estimated with machine learning and graph theory
We provide a roads dataset that includes the spatial location of roads, the estimated age of each road, and the predicted traffic volume of each road between 1986 and 2020 in Wyoming, USA. Our annual estimates of traffic volume are available for each road and include estimates for all vehicles and truck only traffic. Moreover, we provide the estimated age of each road, where a minimum...
The Extended Global Lake area, Climate, and Population Dataset (GLCP) The Extended Global Lake area, Climate, and Population Dataset (GLCP)
A changing climate and increasing human population necessitate understanding global freshwater availability and temporal variability. To examine lake freshwater availability from local-to-global and monthly-to-decadal scales, we created the Global Lake area, Climate, and Population (GLCP) dataset, which contains annual lake surface area for 1.42 million lakes with paired annual basin...
Thin section images, automated mineralogy scans, lithogeochemistry, and Nd-Sr-Pb isotopic analysis of samples from a mostly buried layered mafic intrusion, Wet Mountains, Colorado 2022-2024 Thin section images, automated mineralogy scans, lithogeochemistry, and Nd-Sr-Pb isotopic analysis of samples from a mostly buried layered mafic intrusion, Wet Mountains, Colorado 2022-2024
This dataset includes thin section images, automated mineralogy mineral maps, whole-rock geochemical data, and whole-rock Nd-Sr-Pb isotopic analysis of samples collected from nine mafic-ultramafic outcrops in the Wet Mountains, southern Colorado, during the summer of 2022. These data will accompany an upcoming journal publication and are intended to supplement recently collected airborne...
Eelgrass (Zostera marina) Maps from 2016 and 2020, Izembek Lagoon, Alaska Eelgrass (Zostera marina) Maps from 2016 and 2020, Izembek Lagoon, Alaska
This data package includes 40 geospatial rasters (maps) depicting various metrics about eelgrass (Zostera marina) coverage at Izembek Lagoon, Alaska, during 2016 and 2020. Two maps were produced from two Sentinel-2 satellite images collected on July 1, 2016, and August 14, 2020. Spectral classes derived from each satellite image were annotated and mapped based on data collected in the...
