Madison River near West Yellowstone, MT (YMAD), Yellowstone National Park Sample Collection: Samples were collected near the USGS stream gage 06037500 (Latitude 44°39'25.46", Longitude 111°04'04.67" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were retained for chemical analyses, including an unacidified (FU) sample for determination of anion concentrations and a nitric acid preserved (FA; 1% volume-to-volume concentrated trace-metal grade nitric acid) sample for cation and trace metal analyses. During sample collection, the water temperature, specific conductance, and pH were often measured. Sample Analyses:...

Summary: Siliceous sinter samples were collected from multiple geysers in the Upper Geyser Basin of Yellowstone National Park in 2018. These silica sinter samples were collected and analyzed as a part of a multi-year research investigation into the age and geochemistry of hydrothermal features in the Upper Geyser Basin. Samples were collected along the stratigraphy of each feature. From these samples, we report 10Be, U-series, and 14C ages. Samples collected from Giant and Castle Geyser were further analyzed for their mineralogy, major and trace element concentrations, water content, and rare earth elements. This research was conducted under Yellowstone Research Permit YELL-2018-SCI-8030 and YELL-2018-SCI-5910....

Old Faithful Geyser in the Upper Geyser Basin of Yellowstone National Park is one of the best studied geysers in the world. Under research permit YELL-SCI-8030, samples from 13 silicified tree remnants were collected adjacent to the Old Faithful Geyser cone in April and November 2019. The silicified wood samples were dated using the radiocarbon (14C) method and were analyzed by scanning electron microscope (SEM) to determine the extent of wood silicification. This study was conducted in order to provide new information on the geyser’s past decadal to centennial eruptive activity. Understanding Old Faithful’s past could provide a baseline for understanding future changes in its eruption intervals.

Sample Analyses: X-ray powder diffraction (XRPD) was carried out on samples UGB-TD-24 through UGB-TD-39 (excluding UGB-TD-38) at the U.S. Geological Survey in Menlo Park, CA. Each sample was powdered using an agate mortar and pestle and packed into a shallow well (0.5 mm) aluminum XRPD mount with the knife edge of a spatula to ensure random orientation. Samples were scanned continuously at room temperature from 3.0° 2θ to 80.0° 2θ with a step size of 0.01° 2θ on a Rigaku Multiflex X-ray diffractometer with Cu-Kα radiation with an accelerating voltage of 40.0 kV and a filament current of 20.0 mA. Database Contents: The data files (UGB-TD-XX.csv; where XX is the respective sample ID) contain the angle and intensity...

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 bioaccumulated form in food webs. This data informs the biogeochemical processes controlling the broad range of mercury and methylmercury concentrations observed in the park. Natural abundance mercury stable isotopes were also collected to determine if mercury sources or cycling processes varied between different hydrothermal sources. Data...
The grizzly bear distribution boundary delineates the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was generated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2000 to 2014.

Understanding evolutionary processes that drive population dynamics is critical in ecology. Measuring the performance-density relationship in long-lived mammalian species demands long-term data, limiting the ability to observe such mechanisms. We tested density-dependent (intrinsic) and density-independent (extrinsic) drivers of body composition of grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem over two decades.

Sample Analyses: Samples were analyzed for their major and trace element chemistry using the Applied Spectra Resolution-SE 193nm ArF excimer laser ablation system at the LA-ICP-MS (Laser Ablation Inductively Coupled Plasma Mass Spectrometry) Laboratory, Colorado School of Mines (CSM), Colorado. A small piece (~5 mm by 5-8 mm) was cut from the wavelength dispersive x-ray fluorescence (WDXRF) pellets and mounted on a one-inch glass puck with 25-30 other samples. Samples were polished down to ~0.5 micron with diamond paste and placed in an ablation chamber that holds several sample pucks, a drift monitor, and 18 fused low dilution glass reference materials (made with common USGS, GSJ, etc. standards). All sample glasses...

Sample Analyses: Four samples of silica sinter from Giant and Castle Geysers composed of opal-A or opal-A/C were analyzed for U-Th isotopes at USGS laboratories in Denver, CO (https://www.usgs.gov/centers/gecsc/science/denver-radiogenic-isotope-lab?qt-science_center_objects=0#qt-science_center_objects). Small fragments, weighing approximately 10 g, were cut and polished to enable microsampling using carbide dental burrs. Sub-samples consisted of small pits or trenches that cut across microfabric elements and integrate material weighing 0.082–0.109 g. Resulting powders were digested using concentrated hydrofluoric acid (HF) after spiking with known amounts of a mixed 229Th-233U-236U tracer solution. After evaporation,...

Sample Collection: Field work was conducted in November 2018 in the Upper Geyser Basin. Three sinter samples were collected from Castle Geyser and one sinter sample was collected from Solitary Geyser. At Castle Geyser, an effort was made to identify stable surfaces associated with the oldest exposed stratigraphic levels of sinter deposition, in order to target material emplaced during early stages of hydrothermal activity in the basin. At Solitary Geyser, material was collected from an exposure on the upper surface of a sinter deposit. All four sinter sample locations were selected to coincide with collection sites for material dated by radiocarbon methods, to enable a cross-comparison of results. Sinter was collected...
