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.

Bathymetry and topography data from the Elwha River delta, Washington, September 2010
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
Carbonate geochemistry dataset of the soil and an underlying cave in the Ozark Plateaus, central United States
The nature of carbon (C) cycling in the vadose zone where groundwater is in contact with abundant gas-filled voids is poorly understood. The objective of this study was to trace C cycling in a karst landscape using stable-C isotopes, with emphasis on a shallow groundwater flow path through the soil, to an underlying cave, and to the spring outlet of a cave stream in the Ozark Plateaus of northwest
Data from Mercury Intrusion Porosimetry conducted on samples of a mudstone underlying the Naval Air Warfare Center, West Trenton, NJ
This data set presents the results of conducting Mercury Intrusion Porosimetry on core samples of the mudstone underlying the Naval Air Warfare Center, West Trenton, NJ. The core samples were selected from the continuous core collected from boreholes 83BR-89BR.
Survey of velocity and bathymetery in Hoover Reservoir, ADCP source data, Columbus, OH (August, 2015)
These data were collected using a 600 kHz Rio Grande ADCP (acoustic Doppler current profiler) in mode 12 from a moving boat. The data were georeferenced with a Hemisphere A101 Smart Antenna differential GPS. These data were processed with Teledyne RD Instruments' software, WinRiver II. These data were collected concurrently with several water quality parameters that were collected by an autonomous
Lithologic characterization of cores from boreholes 83BR-89BR collected from the mudstone aquifer underlying the Naval Air Warfare Center, West Trenton, NJ
This data set presents the lithologic interpretation of rock cores from boreholes 83BR-89BR collected from the mudstone aquifer underlying the Naval Air Warfare Center (NAWC), West Trenton, NJ. Continuous core from these boreholes was collected and visually interpreted to identify characteristics of the depositional environment of the mudstone. Three types of mudstone were identified: a black-fis
Database of earthquake ground motions from 3-D simulations on the Salt Lake City of the Wasatch fault zone, Utah
This dataset consists of the processed ground motions from 96 earthquake rupture scenarios for M7 earthquakes on the Salt Lake City segment of the Wasatch fault. Details about the simulation method, ground motion variability and sensitivity of the ground motions to the kinematic rupture parameters are described in the accompanying manuscript. Simulated data is distributed as 5-percent damped respo
Sensor and Location data from Ear Tag PTTs Deployed on Polar Bears in the Southern Beaufort Sea 2009 to 2011
These are data collected from Wildlife Computers ear tag platform transmitter terminals (PTT) deployed on polar bears in the southern Beaufort Sea during the months of March, April, August, September, and October between 2009 and 2011. Purpose is to examine the performance and retention of ear tag satellite transmitters attached to polar bears.
Data associated with Sofaer and Jarnevich 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants'
These data were analyzed for the publication 'Accounting for sampling patterns reverses the relative importance of trade and climate for the global sharing of exotic plants': Aim: Exotic species distributions reflect patterns of human-mediated dispersal, species climatic tolerances, and a suite of other biotic and abiotic factors. The relative importance of each of these factors will shape how the
Datasets from maps of water-level changes in the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, predevelopment (about 1950) to 2015
Dataset of wells used to create map and raster of map of water-level changes in the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming, predevelopment (about 1950) to 2015 and 2013 to 2015.
The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota dataset
The data set consists of data collected in 1995, 1996, and 1997 in wetlands in the Prairie Pothole Region of North Dakota and South Dakota. The data were summarized and used in the analysis for a U.S. Geological Survey Open File Report entitled: The influence of local- and landscape-level factors on wetland breeding birds in the Prairie Pothole Region of North and South Dakota. The data consist of
Plant functional traits, Colorado River, Grand Canyon, 2012-2014Data
These data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data was collected forspecific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon/nitrogen ratio. Seed mass and plant height data were c
The role of alluvial aquifer sediments in attenuating a dissolved arsenic plume data release
In a crude-oil-contaminated sandy aquifer at the Bemidji site in northern Minnesota, biodegradation of petroleum hydrocarbons has resulted in release of naturally occurring As to groundwater under Fe-reducing conditions. This data set was collected for a study that used chemical extractions of aquifer sediments collected in 1993 and 2011-2014 to evaluate the relationship between Fe and As in diffe
