All Data

Data presented are results of surveys and monitoring for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. These data were collected to assess Cactus Wren population status following 3 years of drought and determine the relationships between specific elements of habitat quality, food availability, and Cactus Wren productivity and survival. Surveys were...

This dataset contains annual flow metrics quantifying drought and low streamflows for USGS GAGES-2 gages in the contiguous U.S. satisfying data completeness checks for the periods 1921-2020, 1951-2020, and 1981-2020. The dataset also contains annual climate variables from the USGS Monthly Water Balance Model (MWBM). The dataset provides trend analysis outputs for annual drought and low...

Images of subsurface electrical conductivity are useful for locating fluids and other electrically conductive phases at depth in the Earth. This data release presents electrical conductance maps estimated from a 3D model of the Great Basin, USA, at five different depth ranges, spanning 2 to 200 km depth. Electrical conductance is the integration of electrical conductivity in a depth...

The COAWST modeling system has been used to simulate ocean and wave processes along the of US East Coast and Gulf of Mexico. The grid has a horizontal resolution of approximately 5km and is resolved with 16 vertical terrain following levels. The model has been executed on a daily basis since 2010 with outputs written every hour. Data access is available through a Globus access portal...

This release contains geospatial data digitized from the Map Showing Geology, Structure, and Oil and Gas Fields in the Sterling 1x2 Degree Quadrangle, Colorado, Nebraska, and Kansas (Scott, 1978) and was compiled as part of the National Geologic Synthesis project. The geospatial data depicts the geology of this quadrangle, which is dominated by Quaternary alluvial and aeolian deposits...

The U.S. Department of Agriculture Natural Resources Conservation Service (NRCS) provides funding and technical assistance for the implementation of practices that enable people to conserve, maintain, or improve soil, water, and related natural resources. NRCS conservation practices, or best management practices, relate the conservation practices to conservation practice physical effects...

This table contains geochemical data collected for whole-rock samples from the Columbia River Basalt Group in the western Columbia River Gorge in Oregon and Washington. Most samples were collected by Russell C. Evarts and Richard M. Conrey from 2002 to 2014. Samples were collected during traverses along roads, streams, ridgecrests, and other areas as part of ongoing geologic mapping...

These data were compiled as a part of a landscape conservation design effort for the sagebrush biome, and are the result of applying a spatially explicit model that assessed geographic patterns in sagebrush ecological integrity and used these results to identify Core Sagebrush Areas (CSAs), Growth Opportunity Areas (GOAs), and Other Rangeland Areas (ORAs). Our overall objective in this...

This dataset was produced by the US Geological Survey (USGS) as a supporting dataset to be used for the purpose of calculating stream gage basin characteristics in preparation for the South Carolina StreamStats application. This integer raster dataset represents runoff curve numbers for combinations of hydrologic soils groups and land cover classes within the South Carolina StreamStats...

Illegal logging is one of the leading causes of deforestation today. Sadly, tree species indigenous to regions critical to maintaining Earth?s ecological diversity also possess properties (i.e. appearance, aroma, etc.) desirable to humans, which often leads to exploitation. In 1992, due to illegal logging, Brazilian rosewood (Dalbergia nigra) became the first ever tree species to be...

Ice core from Greenland was melted, filtered, and homogenized. Its stable hydrogen (δ2H) and oxygen (δ18O) isotopic compositions were adjusted to approximately match those of USGS46 ice core water (δ2H = ?235.8 ? and δ18O = ?29.80 ?). This isotopic reference water, USGS46a, was loaded into glass ampules, sealed, autoclaved to eliminate biological activity, and calibrated by dual-inlet...

This data release includes a table of Sr concentrations and 87Sr/86Sr data used to evaluate primary seawater isotope compositions of marine invertebrate shell material used to estimate the Sr-chronostratigraphic age of sediments hosting early Miocene sirenian fossils on Santa Rosa Island of the Channel Island National Park, Ventura County, California
