Published Data Sets

Continuous Data

Link to web page with access to continuous data in the USGS National Water Information System (NWIS) database for all stations with sensors at the Bemidji site. Types of data include: groundwater levels, groundwater temperatures, groundwater specific conductance, unsaturated zone volumetric water content, unsaturated zone temperature, unsaturated zone carbon dioxide concentrations, unsaturated zone oxygen concentrations, precipitation, and lake levels.

Other available data sets

Map interface for viewing and downloading discrete water-level data for most wells at the Bemidji site on a site-by-site basis. This portal is produced through USGS Groundwater Watch for the 'Minnesota Bemidji Toxics Oil Spill Research Site Network'. Water-level data and basic statistics about the entire water-level record for each specific well are provided, if the well was measured at least once during the last 13 months. Water-level data can only be retrieved on a site-by-site basis.

Data Sets from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA (ver. 3.0, April 2020) This USGS Data Release contains many historical data sets, including water, oil, and sediment chemistry data, water- and oil-level data, sediment grain size distribution, and others. The complete 1983-present water- and oil-level data sets are available here.

Sampling site information, well construction details, and data dictionaries for data sets associated with the National Crude Oil Spill Fate and Natural Attenuation Site near Bemidji, Minnesota (ver. 3.0, April 2020) This data release contains all of the current hole construction information and definitions of codes used in the historical data set data release above.

Bemidji ScienceBase Community Page All USGS-authored manuscripts published after 2016 require publication of data. Data sets associated with these manuscripts are available through this ScienceBase community page.

BemidjiQW.zip Zip file with discrete water quality and (eventually) unsaturated zone gas data for the Bemidji Site. The zip file contains data files and associated metadata for water quality data and unsaturated zone gas data collected at the Bemidji site from the 1980s through the current field session (2019 at time of publication). The data contained in this file are from a download from the USGS National Water Information System (NWIS). The water-quality data are primarily field parameter measurements (dissolved oxygen, pH, temperature, and specific conductance) from groundwater wells at the research site from 1998 through the present, though occasional other data are included such as BTEX (benzene, toluene, ethylbenzene, and xylene) and oxygen and dueterium isotopes. The unsaturated zone gas data are from vapor wells installed at the site.

Citing Data Sets

The Site Information data release should be cited whenever you publish data from cores or wells collected at the Bemidji site because it is the definitive location and construction record. This includes publication of site maps with well and core locations (because site locations are in the site construction data release). The full citation is available at the data release landing page.

The Data Sets... data release should be cited whenever you publish the data available through it (for example, water and oil levels). The full citation is available at the data release landing page.

If you use the KML or ArcGIS layers available on the Bemidji spatial data page to publish a figure showing oil body locations, plume extents, 1979 rupture site, or other site infrastructure, cite as [substitute your applicable information in brackets]:

U.S. Geological Survey, [YYYY], U.S. Geological Survey Bemidji Project Web Page, accessed [INSERT DATE], at https://mn.water.usgs.gov/projects/bemidji/spatial/index.html.

If you publish water quality or unsaturated zone gas data available through the BemidjiQW.zip file above, or if you do your own retrieval of discrete or continuous data from the USGS National Water information System (NWIS) database, your publication is required to have the following:

In text citation: (U.S. Geological Survey, YYYY), where YYYY is the year you retrieved the data.

Full citation [substitute your applicable information in brackets]: U.S. Geological Survey, [YYYY], National Water Information System data available on the World Wide Web (USGS Water Data for the Nation), accessed [INSERT DATE], at [https://waterdata.usgs.gov/nwis/ OR MORE SPECIFC URL], doi:10.5066/F7P55KJN.

A table or list of the 15-digit USGS station numbers for which you retrieved data, the date range of data included in the publication, and the 5-character USGS parameter code(s) included in the publication. The 15-digit USGS station numbers are in columns titled "USGS_siteno" and the 5-character parameter codes are in columns titled "parm_cd". Including these details ensures your audience can replicate your data retrieval.
