Yellowstone Thermal Feature Mercury and Methylmercury Characterization Yellowstone Thermal Feature Mercury and Methylmercury Characterization
Data in this data release were obtained from water samples collected under Yellowstone National Park (YNP) Research Permit YELL-05194 in 2017, 2019, and 2020 through the Integrated Yellowstone Studies Project funded by the Mineral Resources Program. These samples were used to assess mercury cycling within YNP. Water samples were analyzed for total mercury and methylmercury, the...
U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2019 – 2020 U.S. Geological Survey Precipitation Chemistry Quality Assurance Project Data 2019 – 2020
The USGS Precipitation Chemistry Quality Assurance Project (PCQA) operates QA programs to challenge and test the National Atmospheric Deposition Program (NADP) data-collection processes for both the National Trends Network (NTN) and Mercury Deposition Network (MDN). PCQA data are available in separate tables for each quality-assurance program: (1) NTN Interlaboratory-comparison, (2) MDN
Apatite and zircon U/Pb and fission track geochronologic and thermochronologic data along the Fall Line of the southeastern United States Apatite and zircon U/Pb and fission track geochronologic and thermochronologic data along the Fall Line of the southeastern United States
This data release contains apatite and zircon U/Pb and fission track data for six samples collected along the Fall Line of the southeastern United States, from Virginia to the Georgia-South Carolina border. The data resolve phases of rapid exhumational cooling in the Permo-Triassic, additional cooling in the Jurassic-Early Cretaceous and slower cooling since the middle of the Cretaceous...
Geochemical reanalysis of rock and sediment samples from the Lower Middle Fork of the Salmon River collected as part of the Idaho Primitive Area Studies in the 1960's through 1980's Geochemical reanalysis of rock and sediment samples from the Lower Middle Fork of the Salmon River collected as part of the Idaho Primitive Area Studies in the 1960's through 1980's
This is a geochemical data set from the reanalysis of 44 rock samples collected between 1966 and 1970, and 107 sediment samples collected in 1966 and 1967. These samples were collected by the U.S. Geological Survey for a study investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the Lower Middle Fork of the Salmon River, including the
