Science Datasets
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.
Basin Characterization Model (BCMv8) monthly recharge and runoff for the Anza-Cahuilla Groundwater Basin, California
This dataset provides monthly and average annual long-term estimates (water years 1981-2010) of gridded recharge and runoff from water years 1896-2018 for the Anza-Cahuilla Groundwater Basin in southern California. Gridded data are available in flat ASCII files (*.asc) in the NAD83 California Teale Albers projection.
San Gorgonio Pass Wind Resource Area Repower Data (2018-2019)
Variation in avian and bat mortality as a function of turbine size was investigated in the San Gorgonio Pass Wind Resource Area near Palm Springs, CA. Five sites were monitored for carcasses by dog-handler teams every 3 days from May 2018 to April 2019.
Astragalus species complex genetic data from southeast Utah (Grand County and San Juan County), USA
These data were compiled to investigate the evolutionary history of Astragalus iselyi, A. sabulosus var. sabulosus, and A. sabulosus var. vehiculus. The data release consists of six text files. One file is a bash script (astragalus_MLE_msms.sh) for generating simulated genetic data.
Northern tamarisk beetle impact and classification maps, Grand Canyon National Park, Arizona
These data are satellite image-derived, classification maps of tamarisk (Tamarisk spp.) along the Colorado River in Grand Canyon National Park from river km 315 to 363, approximately from Parashant Canyon to Diamond Creek tributaries.
Humpback chub spring and fall capture histories in the Little Colorado River, 2009-2019
These data were compiled to examine rates of skipped migration in adult humpback chub that spawn in the Little Colorado River (LCR). These data include mark-recapture information from the lower 13.56 kilometers of the LCR and from the Colorado River, from river kilometer 105.5-145.7 downstream of Glen Canyon Dam.
Mercury Concentrations and Stable Isotopes in Riparian Songbirds and Invertebrates from the Willamette River, Oregon, 2013
This dataset includes bird species, invertebrate order and family, sample identification codes, collection date, latitude, longitude, site name, bird age, invertebrate life stage, invertebrate trophic group, carbon and nitrogen stable isotopes in birds and invertebrates, total mercury concentrations in bird blood, and methylmercury concentrations in composite invertebrates.
Ground Control Point Data from the Outer Banks, North Carolina, post-Hurricane Dorian, September 2019
The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project surveyed 34 features visible from the air to be used as ground control points (GCP) on the Outer Banks, North Carolina, on September 24 and 25, 2019, after the passing of Hurricane Dorian (U.S. landfall on September 6, 2019).
Argon data for Hugub Area, Kesem-Kebena-Dulecha, Ethiopia
Tephra samples were collected by Leah Morgan (now at the U.S. Geological Survey (USGS)) from the Hugub Area, Kesem-Kebena-Dulecha, Afar, Ethiopia. Sanidine grains were separated from the bulk sample and analyzed by argon geochronology at the Scottish Universities Environmental Research Centre, Scotland.
Hydrodynamic model of the lower Columbia River, Washington and Oregon, 2017-2020
A three-dimensional hydrodynamic model of the lower Columbia River (LCR) was constructed using the Delft3D Flexible Mesh (DFM) modeling suite to simulate water levels, flow, and seabed stresses between January 1, 2017, and April 20, 2020.
Elements in elk tissues harvested in pre-uranium mining and non-mining areas, 2019
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.) in elk tissue samples (livers and muscle) collected from tribal hunting grounds (pre-uranium mining site) and an elk farm in Wisconsin (non-mining site) in calendar year 2019.
Elements in Kemp's ridley turtle egg contents collected from failed eggs laid by radio-tagged females along the Texas Gulf coast in 2010-2013
These data are comprised of measurements of elements (i.e., aluminum, iron, vanadium, chromium, cobalt, nickel, copper, zinc, arsenic, selenium, cadmium, tin, antimony, barium, thallium, lead, mercury, sodium, magnesium, potassium, calcium, manganese, and strontium) in Kemp's ridley sea turtle (Lepidochelys kempii) egg contents.
Genomic Data of North American Sea Ducks
This data set describes accession numbers for nucleotide sequence data derived from whole mitochondrial genome and double digest restriction-site associated DNA (ddRAD).
