Soil Biogeochemical Data from a Marine Terrace Soil Climo-Chronosequence Comparison Soil Biogeochemical Data from a Marine Terrace Soil Climo-Chronosequence Comparison
The storage and persistence of soil organic matter (SOM) is of critical importance to soil health, and to the terrestrial carbon cycle with implications for long-term climate change. To better understand the spatio-temporal controls on SOM, we have developed a new dataset spanning two previously described marine terrace soil chronosequences from northern, CA, USA: the Santa Cruz and the...
Concentrations of chlorinated volatile organic compounds and per- and polyfluoroalkyl substances in groundwater and surface water, former Naval Air Warfare Center, West Trenton, New Jersey Concentrations of chlorinated volatile organic compounds and per- and polyfluoroalkyl substances in groundwater and surface water, former Naval Air Warfare Center, West Trenton, New Jersey
This dataset contains a compilation of concentrations of chlorinated volatile organic compounds (VOCs) and per- and polyfluoroalkyl substances (PFAS) in groundwater and surface water sampled at the former Naval Air Warfare Center, West Trenton, New Jersey. Measured VOCs include trichloroethene (TCE), cis- 1,2-dichloroethene (cisDCE), and vinyl chloride (VC). Semi-volatile organic...
Data Release of Basin Characteristics, Generalized Skew Map, and Peak-Streamflow Frequency Estimates in Oklahoma, 2017 (ver. 1.1, September 2020) Data Release of Basin Characteristics, Generalized Skew Map, and Peak-Streamflow Frequency Estimates in Oklahoma, 2017 (ver. 1.1, September 2020)
The U.S. Geological Survey (USGS) Oklahoma-Texas Water Science Center, in cooperation with the Oklahoma Department of Transportation, updated basin-characteristic data for Oklahoma streams with drainage areas of less than 2,510 square miles. Basin characteristics were updated or created for 248 streamgages. The previously published Oklahoma generalized skew map, a necessary element in...
Measurements of Discharge in Small, Low-Flowing Streams Using Multiple Techniques Measurements of Discharge in Small, Low-Flowing Streams Using Multiple Techniques
The accompanying datasets include all field measurements collected as part of a study to evaluate multiple streamflow measurement techniques in small streams throughout the United States. Each individual dataset is paired with a metadata record describing the contents and purpose of that dataset.

The data set contains information on potential population, economic, land cover, and infrastructure groundwater inundation exposure for San Francisco Bay and coastal communities of the state of California, USA. The type of information includes U.S. Census data on the number and types of residents, Data Axle data on numbers and types of employees, county parcel values, HAZUS building...
Qualitative Mineral Potential Map of Tungsten Skarn in the Yukon-Tanana Uplands, Eastern Alaska, USA, 2021 Qualitative Mineral Potential Map of Tungsten Skarn in the Yukon-Tanana Uplands, Eastern Alaska, USA, 2021
The data release includes GIS data that map potential for tungsten skarn mineralization in permissive tracts in the Yukon-Tanana Uplands, Eastern Alaska, along with tables listing keywords and procedures used to produce the permissive tracts and score them for mineral potential.The GIS data are encapsulated in a file geodatabase called "AK_Wskarn_tract.gdb" and are also available in the...
