Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>There are over 10,000 hydrothermal features in Yellowstone National Park (YNP), where waters have pH values ranging from about 1 to 10 and surface temperatures up to 95 °C. Active geothermal areas in YNP provide insight into a variety of processes occurring at depth, such as water-rock and oxidation-reduction (redox) reactions, the formation of alteration minerals, and microbial (thermophile) metabolism in extreme environments. Investigations into the water chemistry of YNP hot springs, geysers, fumaroles, mud pots, streams, and rivers have been conducted by the U.S. Geological Survey (USGS) and other earth-science organizations and academic institutions since 1888 (Gooch and Whitfield, 1888). More recently, USGS researchers have sampled hydrothermal features in YNP at least annually since 1994 (McCleskey and others, 2014, and references within). </SPAN></P><P><SPAN>In this Data Release, the analyses of 751 water samples are reported for numerous thermal and non-thermal features in YNP. These samples were collected beginning in 2009. This report combines water chemistry data presented in McCleskey and others (2014) with newer data collected after 2014. These water samples were collected and analyzed as part of research investigations in YNP on arsenic, iron, nitrogen, and sulfur redox species in hot springs and overflow drainages; the occurrence and distribution of dissolved mercury and arsenic; and general hydrogeochemistry of hot springs throughout YNP. For most samples, data includes water temperature, pH, specific conductance, dissolved oxygen, and concentrations of major cations, anions, trace metals, alkalinity, sulfur redox species (hydrogen sulfide and thiosulfate), nutrients, silica, arsenic and iron redox species, acidity, dissolved organic carbon, and hydrogen and oxygen isotope ratios. For select samples, tritium (3H) and stable carbon isotopes of the dissolved inorganic carbon are presented. In addition, chemical data for river and stream waters were obtained to determine geothermal solute flux from thermal areas throughout YNP. </SPAN></P><P><SPAN>References Cited</SPAN></P><P><SPAN>Gooch, F.A., and Whitfield, J.E., 1888, Analyses of waters of the Yellowstone National Park with an account of the methods of analysis employed: Bulletin 47, p. 84.</SPAN></P><P><SPAN>McCleskey, R.B., Chiu, R.B., Nordstrom, D.K., Campbell, K.M., Roth, D.A., Ball, J.W., and Plowman, T.I., 2014, Water-Chemistry Data for Selected Springs, Geysers, and Streams in Yellowstone National Park, Wyoming, Beginning 2009: doi:10.5066/F7M043FS.</SPAN></P><P><SPAN>Data were downloaded and minimally modified by the Wyoming State Geological Survey (WSGS) in February, 2023 for simplified display on the interactive Geology of Yellowstone Map.

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This database was prepared using a combination of materials that include aerial photographs, topographic maps (1:24,000 and 1:250,000), field notes, and a sample catalog. Our goal was to translate sample collection site locations at Yellowstone National Park and surrounding areas into a GIS database. This was achieved by transferring site locations from aerial photographs and topographic maps into layers in ArcMap. Each field site is located based on field notes describing where a sample was collected. Locations were marked on the photograph or topographic map by a pinhole or dot, respectively, with the corresponding station or site numbers. Station and site numbers were then referenced in the notes to determine the appropriate prefix for the station. Each point on the aerial photograph or topographic map was relocated on the screen in ArcMap, on a digital topographic map, or an aerial photograph. Several samples are present in the field notes and in the catalog but do not correspond to an aerial photograph or could not be found on the topographic maps. These samples are marked with “No” under the LocationFound field and do not have a corresponding point in the SampleSites feature class. Each point represents a field station or collection site with information that was entered into an attributes table (explained in detail in the entity and attribute metadata sections). Tabular information on hand samples, thin sections, and mineral separates were entered by hand. The Samples table includes everything transferred from the paper records and relates to the other tables using the SampleID and to the SampleSites feature class using the SampleSite field.</SPAN></P><P><SPAN>Data were minimally modified by the Wyoming State Geological Survey (WSGS) in March, 2022 for simplified display on the interactive Geology of Yellowstone Map. The SampleSites feature class was joined to the Samples nonspatial table by the SampleSite field. Records where LocationFound = "No" were deleted because these records lack spatial data. The SampleSites feature class was then joined to the HandSamples, ThinSections, and MineralSeparates nonspatial tables by the SampleID field. Records from these three nonspatial tables that are populated (in other words, where the data exist), were assigned a "Yes" value in the "Hand sample?", "Thin section?", and "Mineral separates?" fields respectively; all other records were assigned "No" values in these fields. The joined table was exported to the final feature class, and some fields were added, given different aliases, or had their visibility turned off for simplified display on the interactive Geology of Yellowstone Map. The WSGS has not formally reviewed or quality-controlled these data; users are encouraged to consult the original data source.</SPAN></P></DIV></DIV></DIV>
