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.

Groundwater-level and groundwater-level change contours for the Lahontan Valley shallow aquifer near Fallon, Nevada, 2012

USGS data release of two geospatial datasets from Lahontan Valley near Fallon, NV: contours representing water levels based on depth-to-groundwater measurements made at 98 wells in July 2012 and contours representing water level change in the shallow aquifer (1992-2012) based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013.

Modeled Streamflow Metrics on Small, Ungaged Stream Reaches in the Upper Colorado River Basin: Data

Modeling streamflow is an important approach for understanding landscape-scale drivers of flow and estimating flows where there are no streamgage records. In this study conducted by the U.S. Geological Survey in cooperation with Colorado State University, the objectives were to model streamflow metrics in the Upper Colorado River Basin and identify streams that are potentially threatened.

National Climate Change Viewer (NCCV)

The National Climate Change Viewer (NCCV) allows users to visualize projected changes in climate (maximum and minimum air temperature and precipitation) and the water balance (snow water equivalent, runoff, soil water storage and evaporative deficit) for any state, county and USGS Hydrologic Units (HUC).

Simulated Climate and Vegetation Data for the Northwest United States and Southwest Canada

The northwest United States and southwest Canada data sets consist of statistically-downscaled historical (1901-2001) CRU TS 2.1 and projected future (2001-2099) CMIP3 A2 and A1B climate data (monthly temperature, precipitation, and sunshine), derived bioclimatic variables (e.g., growing degree days), and LPJ-simulated vegetation data on a 30-second grid.

2015 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem

Identifying the locations and causes of grizzly bear mortality is another key component in understanding the dynamics of this population. Over 80% of all documented bear mortalities are human-caused. Tracking human-caused bear deaths helps define patterns and trends that can direct management programs designed to reduce bear mortality.
