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.

Concentrations of pesticides associated with streambed sediment and biofilm in California streams, 2017 Concentrations of pesticides associated with streambed sediment and biofilm in California streams, 2017
Hydrophobic (sediment-associated) pesticides were measured in sediment samples collected from 82 wadeable streams and in biofilm in 54 of those streams in the Central California Foothills and Coastal Mountains ecoregion.115 current-use and 3 legacy pesticides were measured in stream sediment; 93 of the current-use pesticides and the same 3 legacy pesticides were measured in biofilm. On...
Gas emission and ground temperature measurements at Puhimau thermal area, Kilauea Volcano, Hawaii Gas emission and ground temperature measurements at Puhimau thermal area, Kilauea Volcano, Hawaii
Puhimau thermal area, located in the upper East Rift Zone of K?lauea Volcano, Hawai`i formed around 1936 when heat and gases migrated to the surface following a magma intrusion. As of April 2020, the area is about 0.2 km2 in size with regions of steaming ground. The site may be valuable for monitoring changes in gas and heat emissions related to movement of magma down the rift zone. On...
Topographic and Sediment Size Data from Fountain Creek between Colorado Springs and the Confluence with the Arkansas River, Colorado, 2019 Topographic and Sediment Size Data from Fountain Creek between Colorado Springs and the Confluence with the Arkansas River, Colorado, 2019
In 2012, the U.S. Geological Survey (USGS) in cooperation with Colorado Springs Utilities selected 10 study areas along Fountain Creek between Colorado Springs, Colorado and the confluence of Fountain Creek with the Arkansas River for annual geomorphic monitoring. The purpose of this data release is to present topographic survey data, rasters , and sediment size data collected in 2019 as...
Fecal samples collected in May, August, and October 2014 from Little Book Cliffs Herd Management Area, Colorado, for determination of diet, persistence of DNA in the environment, individual identity, and seed germination. Fecal samples collected in May, August, and October 2014 from Little Book Cliffs Herd Management Area, Colorado, for determination of diet, persistence of DNA in the environment, individual identity, and seed germination.
These data were collected in May, August, and October in west central Colorado from a Bureau of Land Management wild horse herd management area (HMA). Samples were already on the ground, not fresh from the horse. The Diet dataset includes proportion of plant species found in fecal samples using two different lab techniques -- plant DNA bar-coding,and microhistology. Results of both...
Vegetation measurements of production and offtake in cottonwood communities of the Great Sand Dunes ecosystem, Colorado, 2005-2009. Vegetation measurements of production and offtake in cottonwood communities of the Great Sand Dunes ecosystem, Colorado, 2005-2009.
These data provide measurements of cottonwood production and herbaceous production in cottonwood communities of the Great Sand Dunes National Park ecosystem in the San Luis Valley of Colorado, from 2005-2009. These data also include cottonwood browsing rates. The study area was stratified into 2 ungulate strata: areas with elk and bison herbivory, and areas with just elk herbivory (bison...
Body condition score of horses wearing radio collars, weekly behavior data of treatments and controls, and monthly descriptive data of collar and radio tag effects, 2015-2016, Oklahoma, USA Body condition score of horses wearing radio collars, weekly behavior data of treatments and controls, and monthly descriptive data of collar and radio tag effects, 2015-2016, Oklahoma, USA
These data are from a study of wild horses and burros wearing radio collars in a captive facility in Oklahoma, USA, for one year. We also evaluated radio transmitter tags (braided into the mane and tails of horses but not burros). We recorded behavior, body condition score, and effects of collars on the necks of horses and burros wearing radio collars and of horses and burros not wearing...
Petrophysical data collected on outcrops and rock samples from the eastern Adirondack Highlands, New York Petrophysical data collected on outcrops and rock samples from the eastern Adirondack Highlands, New York
Petrophysical data were collected in the eastern Adirondack Highlands during several field campaigns in 2016-2017. This data release provides magnetic susceptibility, gamma spectrometry, and density measurements on rock outcrops, hand samples, and during walking surveys. Rock types for the outcrops and samples were identified using standard field methods. Locations of the outcrops or...
Regional scale magnetotelluric data from the Rio Grande Rift and southern Rocky Mountains Regional scale magnetotelluric data from the Rio Grande Rift and southern Rocky Mountains
This dataset consists of 102 magnetotelluric (MT) stations collected in 2012-2014 in the Rio Grande Rift and southern Rocky Mountains. The U.S. Geological Survey acquired these data to improve regional conductivity models of the western United States. This work is in support of studies of the effect of lithospheric modification on electrical resistivity structure and tectonic evolution...
Drought conditions during NHD topographic surveys and other streamflow observations in the Pacific Northwest, USA Drought conditions during NHD topographic surveys and other streamflow observations in the Pacific Northwest, USA
This dataset adds attributes describing the self-calibrated Palmer Drought Severity Index (PDSI) during the observation year of wet/dry streamflow observations collected in the Pacific Northwest, USA. Streamflow observation locations are linked to the nearest National Hydrography Dataset high-resolution (NHD-HR) stream segment to obtain stream order and stream permanence (perennial/non...
Soil sample locations for chronic wasting disease prion surveillance in Grand Teton National Park and National Elk Refuge 2019 Soil sample locations for chronic wasting disease prion surveillance in Grand Teton National Park and National Elk Refuge 2019
A total of 200 soil samples were collected in the Greater Yellowstone Ecosystem in Grand Teton National Park and the National Elk Refuge in July 2019 for chronic wasting disease (CWD) monitoring purposes. To collect samples from locations where ungulates are most likely to be shedding or encountering CWD, we targeted elk collar data locations, known migration routes of mule deer and elk...
Topobathymetric Model of Puget Sound, Washington, 1887 to 2017 Topobathymetric Model of Puget Sound, Washington, 1887 to 2017
To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puget Sound. Puget Sound is located along the northwestern coast of Washington and is part of the Salish Sea. Puget Sound is the third largest estuary in the United States. High...
