Data Releases
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.

Remotely sensed fine-fuel data for Buenos Aires National Wildlife Refuge (BANWR) from 2015 to 2020 Remotely sensed fine-fuel data for Buenos Aires National Wildlife Refuge (BANWR) from 2015 to 2020
These data were compiled to estimate fine-fuel abundance and distribution across the Buenos Aires National Wildlife Refuge in southern Arizona, USA. The objectives of the study were to develop and validate annual estimates of fine fuel (biomass of herbaceous vegetation) for the refuge and to assess changes in fine fuels through time in response to wildfire and prescribed fire. These data...
Soil family particle size class map for Colorado River Basin above Lake Mead Soil family particle size class map for Colorado River Basin above Lake Mead
These data were compiled to support analysis of remote sensing data using the Disturbance Automated Reference Toolset (Nauman et al., 2017). The objective of our study was to assess results of pinyon and juniper land treatments. These data represent major soil types as defined primarily by soil texture and depth, but also geology, parent material, and geomorphology for relevant features...
Data and software code from two long-term experiments (1996-2011 and 2005-2018) at three sites on the Colorado Plateau of North America Data and software code from two long-term experiments (1996-2011 and 2005-2018) at three sites on the Colorado Plateau of North America
These data were compiled to examine how climate change affects biocrust recovery from both physical and climate-induced disturbance. Objective(s) of our study were to uncover the trajectory of biological soil crust communities and soil stability following distrubance and under warming. These data represent biological soil crust surveys under 5 treatments at three sites. These data were...
Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020 Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020
A potentiometric-surface map for spring 2020 was created for the Mississippi River Valley alluvial aquifer (MRVA), which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. The location and water-level altitude in feet for these wells and streamgages in...
Arthropod Abundance Data from the Colville River Delta, Alaska Arthropod Abundance Data from the Colville River Delta, Alaska
This data release contains information on the seasonal diversity and abundance of arthropods collected at the Colville River Delta, Alaska, 2011-2012 and 2014-2107. Researchers with the US Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers concurrently collected arthropods at 3-day intervals...
Environmental Data from the Colville River Delta, Alaska Environmental Data from the Colville River Delta, Alaska
This data release contains two tables with information on seasonal values for temperature, wind, and snow cover collected at the Colville River Delta, Alaska, 2011-2018. Researchers with the U.S. Geological Survey used an on-site weather station to automatically record the temperature and speed and direction of the wind across the duration of their field season. Researchers also...
Avian Demographic Data from the Colville River Delta, Alaska Avian Demographic Data from the Colville River Delta, Alaska
This data release contains multiple tables with information on avian demographics collected at the Colville River Delta, Alaska, 2011-2018. Researchers with the U.S. Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers monitored the nests of geese, shorebirds, and landbirds at this study site
Data on barium, strontium, cobalt, and nickel plumes formed during microbial iron-reduction on sediments and in water from a crude-oil-contaminated aquifer, Bemidji, Minnesota (2009-2019) Data on barium, strontium, cobalt, and nickel plumes formed during microbial iron-reduction on sediments and in water from a crude-oil-contaminated aquifer, Bemidji, Minnesota (2009-2019)
This U.S. Geological Survey (USGS) Data Release provides concentrations from groundwater and soil extracts for iron (Fe), barium (Ba), strontium (Sr), cobalt (Co), and nickel (Ni). Groundwater analyses for pH and alkalinity are also included. Samples were collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site, near Bemidji MN (USA) between 2009-2019. The...
Impacts of extreme environmental disturbances on survival of piping plovers breeding in the Great Plains, and wintering along the Gulf of Mexico and Atlantic Coasts, 2012-2019 Impacts of extreme environmental disturbances on survival of piping plovers breeding in the Great Plains, and wintering along the Gulf of Mexico and Atlantic Coasts, 2012-2019
We present one tabular data file to evaluate piping plover (Charadrius melodus) seasonal (breeding and nonbreeding) adult survival. These data were part of a study to examine adult (n = 3474) survival during 2012-2019 at breeding regions within the Northern Great Plains and nonbreeding regions in the Gulf and southern Atlantic Coasts of North America. This file includes USGS-funded data...
Airborne Volcanic Gas Measurements at Iliamna Volcano, Alaska 2004-2017 Airborne Volcanic Gas Measurements at Iliamna Volcano, Alaska 2004-2017
This release presents data collected during airborne volcanic gas monitoring flights at Iliamna Volcano, Alaska, that were completed between 2004-2017. Instrumented fixed-wing aircraft were used to collect in situ trace gas measurements of volcanic carbon dioxide (CO2), sulfur dioxide (SO2), and hydrogen sulfide (H2S). The sensor payload also included an upward-looking correlation...
Locations of Dams and Basins in South Carolina, derived from U.S. Army Corps Engineers National Inventory of Dams Locations of Dams and Basins in South Carolina, derived from U.S. Army Corps Engineers National Inventory of Dams
Reliable peak-streamflow information is critical for proper design of stream-related infrastructure, such as bridges, and StreamStats is a Web-based Geographic Information Systems (GIS) application that provides a user-friendly interface to estimate peak flows (https://streamstats.usgs.gov/ss/). StreamStats develops these peak-flow estimates using basin characteristics for the entire...
Occupied Range of the Yellowstone Grizzly Bear 2006-2020 Occupied Range of the Yellowstone Grizzly Bear 2006-2020
The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2006-2020. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation.The boundary was delineated...
