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.
Water-level and digital data for the Elkhorn and Loup River Basins groundwater flow model, Phase Three
This updated study focused on a 30,000-square-mile area of the High Plains aquifer and constructed regional groundwater-flow models to evaluate the effects of groundwater withdrawal on stream base flow in the Elkhorn and Loup River Basins, Nebraska.
2018 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.
Shapefile of the flood-inundation maps for the Salamonie River at Portland, Indiana
Digital flood-inundation maps for a 6.5-mile reach of the Salamonie River at Portland, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at https://water.usgs.gov/...
Monitoring Hawaiian Biodiversity: Pilot study to assess changes to Hawaii Island forest birds and their habitat - 2015 vegetation species dataset
The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and...
Electrical Resistivity Tomography Data at Fort Irwin National Training Center, San Bernardino County, California, 2015 and 2017
The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 mi north-northeast of Barstow, California, covers approximately 1,177 square miles, and is comprised of ten groundwater basins, three of which have been subdivided into subbasins on the basis of additional hydrologic testing. Since the early 1990s, the U.S. Geological Survey (USGS) has been studying water resources...
Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889-2012
The dataset includes 492 digitized prints of large-format photographs from 160 viewpoints. A separate metadata file "Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889-2012" describes a comma-delimited file of descriptive information. The viewpoints were first photographed by Stanton in 1889, and then re-photographed in about 1991, 2010 and sometimes other years. This...
Monitoring Hawaiian Biodiversity: Pilot study to assess changes to Hawaii Island forest birds and their habitat - 2015 vegetation structure dataset
The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and...
Experimental infection of Tadarida brasiliensis with the fungus that causes white-nose syndrome: hibernation data
This dataset includes skin temperatures of twelve Tadarida brasiliensis held in environmental chambers maintained at 7.7 (SD 0.9) °C and 91.8 (SD 0.8) % relative humidity to induce and support hibernation for up to 3 months. Bats were randomly assigned to infected and control groups at the start of the experiment and infected with conidia of Pseudogymnoascus destructans or a sham...
Catalogue of Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889-2012
This metadata references a comma-delimited file describing 492 digitized prints of large-format photographs from 160 viewpoints. The photographic images themselves are referenced in a separate metadata file entitled "Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889-2012". The viewpoints were first photographed by Stanton in 1889-1890, and then re-photographed in...
Data on the number of open fruit on individual Hibiscidelphus giffardianus plants in Hawaii Volcanoes National Park in a site with rats removed and control site, October 2016 to August 2017
This study aims to evaluate the effect of rat population control on the ability of Hibiscadelphus giffardianus to successfully establish seedlings. We compared H. giffardianus fruiting and recruitment in a stand treated for rats and a neighboring control stand. The study was conducted in two neighboring kīpuka, Kīpuka Puaulu and Kīpuka Kī, which are patches...
Land-Cover Map for the Island of Maui, Hawaii, 2017 (version 1.2, November 2018)
This dataset describes land cover and vegetation for the island of Maui, Hawaii, 2017, hereinafter the 2017 land-cover map. The 2017 land-cover map is a modified version of the 2010 land-cover map included in the geospatial dataset titled "Mean annual water-budget components for the Island of Maui, Hawaii, for average climate conditions, 1978-2007 rainfall and 2010 land cover (version 2.0)" by...
Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889, 1991, 2010 and other years
The viewpoints were first photographed by Stanton in 1889, and then re-photographed in about 1991, 2010 and sometimes other years. This set of photos focuses on change in riparian vegetation and partially overlaps a larger set of Stanton viewpoints re-photographed by Webb and others and available at http://...
