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.

2017 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.

DATA RELEASE - Water Classification of The Colorado River Corridor, Grand Canyon, Arizona, 2013—Data

These data are classified maps of water in the Colorado River at a discharge of approximately 227 meters squared/second in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona. The data are derived from interpretation of multispectral high resolution airborne imagery that was acquired in May 2013.

DATA RELEASE - Southwest Exotic Mapping Program (SWEMP) Database, 2007

The Southwest Exotic Plant Mapping Program (SWEMP) is a collaborative effort to compile and distribute regional data on the occurrence of non-native invasive plants in the southwestern U.S. The database represents the known sites of non-native invasive plant infestations within AZ and NM, and adjacent portions of CA, CO, NV and UT. These data were collected from 1911to 2006.

Climate Impact Meteorological Stations (CLIM-MET) Data and Repeat Photography

Meteorological data and repeat photography captured at Climate Impact Meteorological (CLIM-MET) stations located in the Canyonlands National Park and Mojave National Preserve. Data from ecologically sensitive sites in the Southwest help determine the distribution and types of surficial deposits and the processes responsible for the deposits, and contribute to understanding vegetation distribution.

Dust Event Detection

A catalog of dust events in the southwestern United States since 2009. Dust emission from sources in the southwestern United States is important on local and regional scales because of its effects on air quality, human health and safety, snow melt timing and water management, and on ecosystem function through the depletion and (or) addition of soil nutrients.
