Data and Tools

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.

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.

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.
