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.

Geochemical data for stream water and stream sediment samples from the northeast part of the Tanacross quadrangle, Alaska Geochemical data for stream water and stream sediment samples from the northeast part of the Tanacross quadrangle, Alaska
This data release is part of a study designed to test geochemical methods that best delineate known mineral deposits in the northeast part of the Tanacross 1 x 3 quadrangle, within the Yukon-Tanana Upland region, Alaska. The total area sampled is about 3,200 km2. Extensive tundra cover and patchy spruce/alder vegetation and very limited outcrop exposure characterize the area. Soils and...
Bathymetry and topography, video observation, and derived benthic habitat data offshore of Seattle, Washington Bathymetry and topography, video observation, and derived benthic habitat data offshore of Seattle, Washington
In 2010, the U.S. Environmental Protection Agency, Region 10, initiated the Puget Sound Scientific Studies and Technical Investigations Assistance Program, which was designed to support research for implementing the Puget Sound Action Agenda. The Action Agenda was created because Puget Sound was designated as one of 28 estuaries of National Significance under section 320 of the Clean...
Whole rock geochemical data from the eastern part of the Yukon-Tanana Upland region, Alaska, USA Whole rock geochemical data from the eastern part of the Yukon-Tanana Upland region, Alaska, USA
This data release is part of a 2016-2019 study on the geology, geochemistry and geochronology of ore systems in the eastern Yukon-Tanana Upland region, Alaska. Whole rock chemistry was conducted on 185 samples, mostly from Au prospects, with lesser samples from porphyry Cu prospects. Geographically, most samples are from gold prospects near the Pogo Au mine and east to Black Mountain in...

National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources - data release National assessment of carbon dioxide enhanced oil recovery and associated carbon dioxide retention resources - data release
In 2020, the U.S. Geological Survey (USGS) completed a probabilistic assessment of the volume of technically recoverable oil resources available if current carbon dioxide enhanced oil recovery (CO2-EOR) technologies were applied in amenable oil reservoirs underlying the onshore and State waters area of the conterminous United States. The assessment also includes estimates of the...
Airborne electromagnetic and magnetic survey data and inverted resistivity models, Cedar Rapids, Iowa, May 2017 Airborne electromagnetic and magnetic survey data and inverted resistivity models, Cedar Rapids, Iowa, May 2017
Airborne electromagnetic (AEM) and magnetic survey data were collected in collaboration with the Iowa Water Science Center for the City of Cedar Rapids to the west of Cedar Rapids, Iowa. The survey was flown between May 4 and May 5, 2017 along 347 line kilometers. Electromagnetic data were acquired using RESOLVE frequency-domain helicopter-borne electromagnetic system. Magnetic data were...
