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.

Point Measurements of Surface Mass Balance, Eklutna Glacier, Alaska, 2008-2015
This data set consists of a time-series of direct measurements of glacier surface mass balance, at Eklutna Glacier, Alaska. It includes seasonal measurements of winter snow accumulation and summer snow and ice ablation.
Mechanisms of aquatic species invasions across the South Atlantic Landscape Conservation Cooperative region
Various analyses using modeling techniques and exploratory statistics were performed on the U.S. Geological Survey Nonindigenous Aquatic Species Database with the primary objective of determining the most appropriate use of presence-only data as it relates to invasive species in the South Atlantic Landscape Conservation Cooperative region from southern Virginia to northern Florida.
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, February 2016
Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system
Data compilation of soil respiration, moisture, and temperature measurements from global warming experiments from 1994-2014
This dataset is the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3800 observations representing 27 temperature manipulation studies, spanning nine biomes and nearly two decades of warming experiments. Data for this study were obtained from a combination of unpublished data and published literature values. We find that although warming increa
Tables supporting improved EA-Cr_HTC hydrogen-isotope technique for halogen- and S-bearing organic compounds
Accurate hydrogen isotopic analysis of halogen- and sulfur-bearing organics has not been possible with traditional high-temperature conversion (HTC) because the formation of hydrogen-bearing reaction products other than molecular hydrogen (H2) is responsible for non-quantitative H2-yields and possible hydrogen isotopic fractionation. The elemental analyzerchromium/high temperature conversion react
Irrigation water use in Kansas, 2014
This U.S. Geological Survey (USGS) Data Release represents geospatial and tabular data on irrigation water use in Kansas. The data release was produced in compliance with open data requirements. The dataset consists of 3 separate items with similar attributes aggregated to different geographic extents: 1. Kansas counties; 2. Kansas regional planning areas used in the Kansas Water Plan; and 3.
Airborne Geophysical Surveys over the Eastern Adirondacks, New York State
Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic and radiometric (gamma spectrometry)
Shakemap earthquake scenario: Building Seismic Safety Council 2014 Event Set (BSSC2014)
This is a catalog of earthquake scenarios, represented as ShakeMaps. A ShakeMap is a USGS product that facilitates communication of earthquake effects by portraying a map of the severity of shaking. Maps of shaking severity are provided in terms of macroseismic intensity, peak ground acceleration, peak ground velocity, and spectral accelerations (at 0.3, 1.0 and 3 sec oscillator periods).
Winter-spring streamflow volume and timing data for 75 Hydroclimatic Data Network-2009 basins in the conterminous United States 1920-2014
This dataset contains gage information for 75 Hydroclimatic Data Network-2009 basins in the conterminous United States and associated annual runoff volume, winter-spring runoff volume, and winter-spring runoff timing data 1920-2014, as well as trend results for WSCVD and WSV for periods 1920-2014, 1940-2014, and 1960-2014.
Low-pathogenic avian influenza viruses in wild migratory waterfowl in a region of high poultry production, Delmarva, Maryland
Migratory waterfowl are natural reservoirs for low pathogenic avian influenza viruses (LPAIV) and may contribute to the long-distance dispersal of these diseases as well as spillover into domestic bird populations. Surveillance for AIVs is critical to assessing risks for potential spread of these diseases among wild and domestic bird populations. The Delmarva Peninsula on the east coast of the U.S
Inorganic and organic concentration data collected from 38 streams in the United States, 2012-2014, with supporting data, as part of the Chemical Mixtures and Environmental Effects Pilot Study
This USGS data release contains station and laboratory method information and geospatial information, as well as concentration results for inorganic and organic compounds and bioluminescent yeast estrogen screen and transgenic zebrafish embryo estrogren bioassay, analyzed at 38 sites in 25 states as part of the Chemical Mixtures and Environmental Effects Pilot Study, 2012-2014.
Inventory of rock avalanches in western Glacier Bay National Park and Preserve, Alaska, 1984-2016: a baseline data set for evaluating the impact of climate change on avalanche magnitude, mobility, and frequency
The effects of climate change have the potential to impact slope stability. Negative impacts are expected to be greatest at high northerly latitudes where degradation of permafrost in rock and soil, debuttressing of slopes as a result of glacial retreat, and changes in ocean ice-cover are likely to increase the susceptibility of slopes to landslides. In the United States, the greatest increases in
