During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential sources of drinking or agricultural water. In addition to waters co-produced with hydrocarbons, geothermal development or exploration brings deep formation waters to the surface for possible sampling. This U.S. Geological Survey (USGS) Produced Waters Geochemical Database, which contains geochemical and other information for 114,943 produced water and other deep formation water samples of the United States, is a provisional, updated version of the 2002 USGS Produced Waters Database (Breit and others, 2002). In addition to the major element data presented in the original, the new database ...

The National Geologic Map Database (NGMDB) is a Congressionally mandated national archive of geoscience maps, reports, and stratigraphic information. The Geologic Mapping Act of 1992 and its Reauthorizations calls for the U.S. Geological Survey and the Association of American State Geologists (AASG) to cooperatively build this national archive, according to technical and scientific standards whose development is coordinated by the NGMDB. The NGMDB consists of a comprehensive set of publication citations, stratigraphic nomenclature, downloadable content in raster and vector formats, unpublished source information, and guidance on standards development. The NGMDB contains information on more than 110,000 maps and related geoscience reports published from the early 1800s to the present day, by more than 630 agencies, universities, associations, and private companies.

Distributed archive of standardized geoscience information.

Publications were located using the Web of Science, Google Scholar, and Clearinghouse for Dam Removal Information.

This data release provides the U.S. Geological Survey (USGS) Spectral Library Version 7 and all related documents. The library contains spectra measured with laboratory, field, and airborne spectrometers. The instruments used cover wavelengths from the ultraviolet to the far infrared (0.2 to 200 microns). Laboratory samples of specific minerals, plants, chemical compounds, and man-made materials were measured. In many cases, samples were purified, so that unique spectral features of a material can be related to its chemical structure. These spectro-chemical links are important for interpreting remotely sensed data collected in the field or from an aircraft or spacecraft. This library also contains physically-constructed as well as mathematically-computed mixtures. Measurements of rocks, soils, and natural mixtures of minerals have also been made with laboratory and field spectrometers. Spectra of plant components and vegetation plots, comprising many plant types and species with v ...

From the site: "A cells polygon feature class was created by the U.S. Geological Survey (USGS) to illustrate the degree of exploration, type of production, and distribution of production in the State of Kentucky. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or the type of production of the wells located within the cell is unknown or dry. Data were retrieved from the Kentucky Oil and Gas Well Records database and saved as a shapefile of oil and gas well locations for Kentucky. Cells were developed as a graphic solution to overcome the problem of displaying proprietary well data. No proprietary data are displayed or included in the cell maps. The data are current as of 2005."

The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. This USGS Data Release archives and makes available all measurements from 2016-2021. Water-quality constituent measurements were collected aboard a research vessel. Sensor constituents include salinity, temperature, oxygen, and light attenuation coefficient. From these constituents, three parameters are derived: ratio of chlorophyll-a and pheopigments, oxygen percent saturation, and density as Sigma-t. Water sample constituents collected for later analysis include chlorophyll-a, suspended particulate matter, nitrate, nitrite, ammonium, silicate and phosphate. These discrete water samples were collected at near surface (2m) by a fixed depth pump or at depth using a Niskin water sampler on a depth-marked line. The sampling was conducted monthly at 37 fixed sampling locations along a 145-km transect from lower South San Francisco Bay to the lower Sacramento River. Additional sampling cruises at a subset of stations (South and Central Bay) were conducted 0-3 times a month. All stations are listed in the station _location table (SFBay_TableofStationLocations.csv) and standard stations are shown on the map (sfbaymap.jpg). A prior USGS Data Release contains the 1969-2015 data https://www.sciencebase.gov/catalog/item/5841f97ee4b04fc80e518d9f. The project website contains more details about this research program and data collection https://sfbay.wr.usgs.gov/access/wqdata/. The website includes a public database where data from all program years can be accessed and downloaded https://sfbay.wr.usgs.gov/water-quality-database/ Please see the VersionHistory.txt for a detailed list of the updates from previous versions.

The U.S. Geological Survey maintains national data bases of water-use information. The data are collected and compiled every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. County, state, and national water-use estimates may be downloaded from the National Water Information System Web (NWISWeb) interface, Water Data for the Nation, by selecting the Water Use button or data category pull-down. Data on NWISWeb represent the current best estimates, and may have been revised from previous publications. Data available from the USGS County Water-Use generally reflect the published report, and may have been revised in subsequent analyses. Note: State-level data from 1950-1980 and watershed data are not available on NWISWeb, but they can be downloaded USGS County Water-Use Data link.
