Kolmakof Mine is the only inactive mine in the study area that contains mercury deposits and recorded contamination.
Locational data was derived from the Alaska Department of Environmental Conservation (DEC) Contaminated Sites Database and cross referenced to the DEC Contaminated Sites with Mercury report (http://dec.alaska.gov/eh/mercury/contaminatedSites.html) in order to identify sites that were active and contaminated with mercury. The attribute Hg_Cont was added to identify and sort these sites (1=mercury contaminated)
This dataset was developed for the BLM Rapid Ecoregional Assessment for the Central Yukon and contains a database of descriptions of historic (inactive and closed) mines based on the Alaska Resource Data File (ARDF).

This dataset was developed for the BLM Rapid Ecoregional Assessment for the Central Yukon and contains a database of descriptions of active mines based on the Alaska Resource Data File (ARDF).
This dataset includes field hydrologic measurements and laboratory analyses of surface and pore waters, sediments, benthic plants/biofilms, and biota along the Middle Snake River upgradient of the Hells Canyon Complex. The study region for this work focuses on a section of the Snake River heavily utilized for agriculture, with complex systems of irrigation diversion and return drainage, spanning 164 km above the Hells Canyon Complex (Idaho, Oregon). The goal of this study was to identify potential loading sources of methylmercury from the upgradient Snake River into the reservoir complex, with a focus on the tributaries, irrigation return drains, and riparian zones adjacent to agricultural lands along the river....
This data release contains the U.S. salient statistics and world production data extracted from the MERCURY data sheet of the USGS Mineral Commodity Summaries 2023.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geospatial data set represents about 2,500 locations of boreholes, shafts, tunnels, and drifts on and around the Nevada Test Site (NTS) where rock-samples have been collected. Information from the rock-samples is summarized for each hole and includes lithologic descriptions, physical and mechanical properties, fracture characteristics, and hydraulic properties where holes were completed below the water table. The digital data...
Mariner 10 data include complete photographic coverage of the quadrangle at a resolution of about 2 km. In addition, twelve stereopairs cover scattered areas in the quadrangle (Davies and others, 1978, p. 114-115); these photographs were used to supplement the geologic interpretation. About 10° of longitude of the H-13 quadrangle (Solitudo Persephones Province) adjacent to the west is included in the map area because not enough Mariner 10 data were acquired of this quadrangle to justify the production of another map.

This dataset includes shallow surface sediment (top 0–2 cm interval) constituent concentration data (primarily) and microbial methylmercury production potential rate data (limited) collected from the Cache Creek Settling Basin (CCSB), Yolo County, California, between April 2010 and July 2017. The dataset includes up to 706 observations (including field replicates) per sediment parameter, reflecting 93 unique sampling locations, with each location having been sampled from 1 to 28 times (excluding field replicates) over this 8-year period. There were four spatially intensive field campaigns conducted (February–March 2013, May 2013, October–November 2014, and January–March 2015), during which at least 90 sites were...
This dataset includes the field measurements and laboratory analyses of surface water, seston, and sediment collected from Lake Powell, within Glen Canyon National Recreation area (GLCA), during high flow (May-June 2014) and low flow (August 2015) conditions. The study area includes 12-13 sampling sites that follow a transect spanning the entire length of the reservoir from the Colorado River inflow to the Glen Canyon dam, as well as the San Juan River arm, the Escalante River arm and West Canyon. Bed sediment samples were analyzed for mercury speciation, methylmercury production and degradation rates, total reduced sulfur, iron speciation, organic content, and 16S rRNA gene templates as a proxy for microbial abundances....
This dataset includes mercury and other constituent concentration and physical properties data for surface sediment, pore water and surface water collected as part of the South San Francisco Bay Salt Pond Restoration Phase 1 (2010 to 2018) studies. The overarching focus of these studies was to monitor mercury (Hg) biogeochemistry in both sediment and water in response to management actions associated with the conversion of former salt producing ponds to contemporary wetland habitat. The two primary management actions included the breaching of Pond A6 during December 2010, and the construction and operation of an adjustable tidal control structure (TCS) associated with the Pond A5/A7/A8 Complex beginning in June...

As part of the Triangle Area Water Supply Monitoring Program, the U.S. Geological Survey conducted a study to evaluate the occurrence and distribution of mercury in 14 streams and 15 reservoirs in the Triangle area of North Carolina. This Data Release contains the associated data described in the Scientific Investigations Report, "Occurrence and Distribution of Mercury in Streams and Reservoirs in the Triangle Area of North Carolina, July 2007 – June 2009". Water samples were collected seasonally between July 2007 and June 2009 for laboratory analysis of mercury, organic carbon, chlorophyll a, sulfate, and suspended sediment. Field measurements of dissolved oxygen, pH, water temperature, and specific conductance...

The U.S. Geological Survey (USGS) has undertaken a mineral resources assessment for tungsten for a portion of the Great Basin in parts of western Nevada and east-central California. This data release provides the Great Basin Tungsten Database: the geospatial and geologic data, and results of chemical analyses for 46,955 samples collected in the assessment area, extracted from the USGS National Geochemical Database. These rock records were collected as part of various programs and projects at the USGS and analyzed from 1963 to 2015. The database represents rock records, each comprising one best value chemical determination for each analyzed chemical species, that include skarns, carbonate lithologies (for example,...
